Yamaha GTS1000 The Yamaha GTS1000 is a sport-touring motorcycle introduced by Yamaha in 1993, sold until 1994 in the United States, and sold elsewhere until 1999. It is notable for its forkless front suspension, specifically a RADD, Inc., front suspension designed by James Parker. This suspension provided improved stability under braking, but the improvement did not justify the additional cost for the consumer, and the bike was not commercially successful. The GTS1000 also had advanced technologies not normally found on motorcycles at the time, such as electronic fuel injection, ABS brakes, and a catalytic converter. The engine was taken from

Etsuo Matsuki and his team developed another interesting feature to increase TDM engine torque and power: A variable intake duct effectively brings out the full potential of the new injection system. The air cleaner box will automatically adjust the air intake volume in accordance with engine rpm. Below 4000rpm the duct closes down about one-third of the intake area. The result is amazing: when suddenly opening the throttle, the new 900 twin pulls stronger than ever without any hesitation.

1970s. Open-loop fuel injection systems had already improved cylinder-to-cylinder fuel distribution and engine operation over a wide temperature range, but did not offer further scope to sufficiently control fuel/air mixtures, in order to further reduce exhaust emissions. Later closed-loop fuel injection systems improved the air–fuel mixture control with an exhaust gas oxygen sensor. Although not part of the injection control, a catalytic converter further reduces exhaust emissions. Fuel injection was phased in through the latter 1970s and 80s at an accelerating rate, with the German, French, and U.S. markets leading and the UK and Commonwealth markets lagging somewhat.

in addition to trucks that compete in NASCAR's Camping World Truck Series. During the 1957 NASCAR Grand National season, president of NASCAR, Bill France, Sr., immediately banned fuel injection from NASCAR. This ruling was in result to the dominance of the 1957 Chevrolet. General Motors did not offer many 1957 Chevrolet stock productions with mechanical fuel injection. However, enough were produced to allow it into NASCAR competition due to homologation rules. This ban on fuel injection would continue into the 21st century. Initially, NASCAR indicated that it would transition to fuel injection midway through the 2011 season. They ultimately decided

governments imposed increasingly strict exhaust emission regulations. During that time period, the vast majority of gasoline-fueled automobile and light truck engines did not use fuel injection. To comply with the new regulations, automobile manufacturers often made extensive and complex modifications to the engine carburetor(s). While a simple carburetor system is cheaper to manufacture than a fuel injection system, the more complex carburetor systems installed on many engines in the 1970s were much more costly than the earlier simple carburetors. To more easily comply with emissions regulations, automobile manufacturers began installing fuel injection systems in more gasoline engines during the late

to operate under a variety of different conditions (such as when starting, the engine’s speed and load, atmospheric and engine temperatures, altitude, ignition timing, etc.) electronic fuel injection (EFI) systems were developed that relied on numerous sensors and controls. When working together, these electronic components can sense variations and the main system computes the appropriate amount of fuel needed to achieve better engine performance based on a stored "map" of optimal settings for given requirements. in 1953, the Bendix Corporation began exploring the idea of an electronic fuel injection system as a way eliminate the well known problems of traditional

Efficient Dynamics EfficientDynamics is a set of technologies that are defined by BMW in its products to maximise performance, reduce CO2 emissions and reduce fuel consumption. BMW's common rail injection involves managing the fuel injection at every stage from pre injection to delivery with one common rail. This improves fuel delivery and power delivery. The stop-start feature will automatically switch off the engine when the car is idling at a complete stop. This reduces fuel consumption while idling for extended periods.

Depending on the system design, the timing of when injector opens is either relative each individual cylinder (for a sequential fuel injection (SFI) system), or injectors for multiple cylinders may be signalled to open at the same time (in a batch fire system). The relative proportions of air and fuel vary according to the type of fuel used and the performance requirements (i.e. power, fuel economy, or exhaust emissions).

Fuel injection Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. All diesel engines use fuel injection by design. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. On petrol engines, fuel injection replaced carburetors from the 1980s onward. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies

In Australia, the summer heat caused petrol in the electric fuel pump to vapourise, resulting in frequent malfunctions. Although the injection system had proven itself in international competition, it lacked altitude compensation to adjust the fuel mixture at altitudes greater than above sea level. The Lucas system proved unpopular: Lucas did not want to develop it further, and Standard-Triumph dealers were reluctant to attend the associated factory and field-based training courses.

fuel is sprayed down towards the burner by the single orifice injector nozzle. At this time the technology did not exist to manufacture nozzles with multiple orifices and diesels used high pressure air to spray the fuel directly into the cylinder. L'Orange also discovered that indirect injection diesel engines ran more smoothly and quietly than direct injection engines. Use of a precombustion chamber also reduced stress on the engine's structure, so that it could be made less heavy than a direct injection engine. However, indirect injection engines require higher compression ratios, about 20:1, to compensate for the greater surface to

advantages over gasoline-powered engines: Diesel's original engine injected fuel with the assistance of compressed air, which atomized the fuel and forced it into the engine through a nozzle (a similar principle to an aerosol spray). The nozzle opening was closed by a pin valve lifted by the camshaft to initiate the fuel injection before top dead centre (TDC). This is called an air-blast injection. Driving the compressor used some power but the efficiency was better than the efficiency of any other combustion engine at that time. Also, air-blast injection made engines very clunky and heavy and did not allow for

The fuel injection systems of the Daimler-Benz DB 605 aircraft engine (as used in the Messerschmitt Bf 109 WW2 fighter and manufactured postwar under licence by Svenska Flygmotor) were equipped with L'Orange fuel injectors fed by a Bosch injection pump. Prosper L'Orange Prosper L'Orange (born 1 February 1876, Beirut; died 30 July 1939, Stuttgart) was a German engineer and inventor who pioneered the precombustion chamber (or prechamber), which made possible high-speed diesel engines that did not require an air compressor,

The engines did not start as well on distillate, so typically a small auxiliary gasoline tank was used for cold starting, and the fuel valves were adjusted several minutes later, after warm-up, to switch to distillate. Engine accessories such as vaporizers and radiator shrouds were also used, both with the aim of capturing heat, because when such an engine was run on distillate, it ran better when both it and the air it inhaled were warmer rather than at ambient temperature.

The 190 E (E for Einspritzung, or Fuel Injection) model uses the Bosch KE-Jetronic Multi-Point Fuel Injection to meter fuel instead of the carburetor of 190 models. Thanks to their fuel injection system, 190 E models made more power and were more fuel efficient when compared to non-fuel injected 190 models. In 1982, the first available models were the 190 and 190 E. Each was fitted with an M102 inline-4 engine.

Indirect injection Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. In the last decade, gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection. However, certain manufacturers such as Volkswagen and Toyota have developed a 'dual injection' system, combining direct injectors with port (indirect) injectors, combining the benefits of both types of fuel injection. Direct injection allows the fuel to be precisely metered into the combustion chamber under

Gasoline direct injection Gasoline direct injection (GDI) (also known as petrol direct injection, direct petrol injection, spark-ignited direct injection (SIDI) and fuel-stratified injection (FSI)), is a form of fuel injection employed in modern two-stroke and four-stroke gasoline engines. The gasoline is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multipoint fuel injection that injects fuel into the intake tract or cylinder port. Directly injecting fuel into the combustion chamber requires high-pressure injection, whereas low pressure is used injecting into the intake tract or cylinder port. In

from around the outside of the exhaust. The system was often used with computerised carburettors or "throttle body injection" systems but is typically not used with multi-point fuel injection, as the problem of fuel falling out of suspension does not occur when the fuel injectors are located close to the inlet valves. There are exceptions to this however. Some vehicles, such as the 1992 and 1993 Fox body Mustangs, do use such as a system even though they have multi-port fuel injection, presumably to help the air-fuel mixture burn at the proper rate in cold weather, as even though the

Many military aircraft engines of the 1940s utilized a pressure carburetor, a type of fuel metering system similar to a throttle body injection system. In a water-injected engine, the pressure carburetor features a mechanical "derichment valve" that makes the system nearly automatic. When the pilot turns on the water injection pump, water pressure moves the derichment valve to restrict fuel flow to lean the mixture while at the same time mixing the water/methanol fluid into the system. When the system runs out of fluid the derichment valve shuts

The reason behind this is that NASCAR didn't take advantage of fuel injection when fuel injected vehicles started to almost completely replace carburetor-powered vehicles during the late 1980s. Outside the NASCAR racing circuit, the American automobile manufacturers would make the final two models to run on carburetors: the 1990 Oldsmobile Custom Cruiser and the 1990 Buick Estate Wagon.

Diesel engines have always used fuel injection system because the timing of the injection initiates and controls the combustion. Autogas engines use either fuel injection systems or open- or closed-loop carburetors. Most internal combustion engines now require a fuel pump. Diesel engines use an all-mechanical precision pump system that delivers a timed injection direct into the combustion chamber, hence requiring a high delivery pressure to overcome the pressure of the combustion chamber.

Branded repair shops and Bosch services became overloaded, and many cars were converted to carburetor. These two-stroke engines were soon superseded by four-strokes. The 1955 Mercedes-Benz 300SL, the first production sports car to use fuel injection, used direct injection.

heavily laden fighters could take off from shorter runways, climb faster, and quickly reach high altitudes to intercept enemy bomber formations. Some fighter aircraft also used water injection for a boost in short bursts during dogfights. As a general rule, the fuel mixture is set at full rich on an aircraft engine when running it at high power settings (such as during takeoff). The extra fuel does not burn; its only purpose is to evaporate to absorb heat. This uses fuel faster and also decreases the efficiency of the combustion process.

Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine, but when information from oxygen sensors is coupled with information from other sources, it can be used to indirectly determine the air–fuel ratio.

Chevrolet introduced a mechanical fuel injection option, made by General Motors' Rochester Products Division, for its 283 V8 engine in 1956 (1957 U.S. model year). This system directed the inducted engine air across a "spoon shaped" plunger that moved in proportion to the air volume. The plunger connected to the fuel metering system that mechanically dispensed fuel to the cylinders via distribution tubes. This system was not a "pulse" or intermittent injection, but rather a constant flow system, metering fuel to all cylinders simultaneously

is then sent through tubing to the injectors, which inject it into the combustion chamber. The header has a high pressure relief valve to maintain the pressure in the header and return the excess fuel to the fuel tank. The fuel is sprayed with the help of a nozzle that is opened and closed with a needle valve, operated with a solenoid. When the solenoid is not activated, the spring forces the needle valve into the nozzle passage and prevents the injection of fuel into the cylinder. The solenoid lifts the needle valve from the valve seat, and fuel under

Multipoint fuel injection (also called PFI, port fuel injection) injects fuel into the intake ports just upstream of each cylinder's intake valve, rather than at a central point within an intake manifold. MPI systems can be sequential, in which injection is timed to coincide with each cylinder's intake stroke; batched, in which fuel is injected to the cylinders in groups, without precise synchronization to any particular cylinder's intake stroke; or

Instead, they provide a precisely controlled air-fuel mixture that quickly and continually cycles between lean and rich combustion. Oxygen sensors monitor the exhaust oxygen content before and after the catalytic converter, and the engine control unit uses this information to adjust the fuel injection so as to prevent the first ( reduction) catalyst from becoming oxygen-loaded, while simultaneously ensuring the second (HC and CO oxidation) catalyst is sufficiently oxygen-saturated.

In a continuous injection system, fuel flows at all times from the fuel injectors, but at a variable flow rate. This is in contrast to most fuel injection systems, which provide fuel during short pulses of varying duration, with a constant rate of flow during each pulse. Continuous injection systems can be multi-point or single-point, but not direct. The most common automotive continuous injection system is Bosch's K-Jetronic, introduced in 1974. K-Jetronic

In fact, most aircraft that use the TCM fuel injection system feature a fuel flow gauge that is actually a pressure gauge calibrated in "gallons per hour" or "pounds per hour" of fuel. From 1992 to 1996 General Motors implemented a system called Central Port Injection or Central Port Fuel Injection.

All share the central task of supplying fuel to the combustion process, but it is a design decision how a particular system is optimized. There are several competing objectives such as: Modern digital electronic fuel injection systems optimize these competing objectives more effectively and consistently than earlier fuel delivery systems (such as carburetors). Carburetors have the potential to atomize fuel better (see Pogue and Allen Caggiano patents). Benefits of fuel injection include smoother

same power output (when cylinder-to-cylinder distribution varies significantly, some cylinders receive excess fuel as a side effect of ensuring that all cylinders receive "sufficient" fuel). Exhaust emissions are cleaner because the more precise and accurate fuel metering reduces the concentration of toxic combustion byproducts leaving the engine. The more consistent and predictable composition of the exhaust makes emissions control devices such as catalytic converters more effective and easier to design. Herbert Akroyd Stuart developed the first device with a design similar to modern fuel injection, using a 'jerk pump' to meter out fuel oil at high pressure to an injector.

Applications: For 1992, the 2.2 received multi-port fuel injection (MPFI) replacing the TBI version in the J-body cars increasing power to and torque to . In the L-body cars it was converted straight to Sequential Fuel injection. In 1994, all 2.2 L engines were updated to sequential multi-port fuel injection and power increased to with

simultaneous, in which fuel is injected at the same time to all the cylinders. The intake is only slightly wet, and typical fuel pressure runs between 40-60 psi. Many modern EFI systems use sequential MPI; however, in newer gasoline engines, direct injection systems are beginning to replace sequential ones. In a direct injection engine, fuel is injected into the combustion chamber as opposed to injection before the intake valve (petrol engine) or a separate pre-combustion chamber (diesel engine). In a common rail system, the fuel from the fuel tank is supplied to the common header (called the accumulator). This fuel
