heavily ribbed sump body is installed. The sump body also helps to reduce engine noise. The engine uses a Bosch high pressure direct injection fuel system with fuel pressure provided by two, cam driven high pressure pumps which are driven by a dedicated camshaft. The high pressure pumps supply the fuel rails which in turn supply the three injectors for that bank with fuel at a controlled pressure. The four camshafts incorporate VCT (variable camshaft timing). VCT allows the timing of the intake and exhaust valves to be adjusted independently of each other. The VCT system is controlled by the Bosch ECM (engine control module) using information from CMP (camshaft position) sensors. The crankshaft features offset journals and a counterweight in place of the deleted pistons and rods. The supercharger is located in the 'vee' of the engine and is driven from the crankshaft by a dedicated secondary drive belt. The engine meets EU5 emission regulations in Europe and Rest of World (ROW) and ULEV 70 emission regulations in North American Specification (NAS) markets. The direct fuel injection system, advanced piston and combustion chamber design and the supercharger provide improved fuel consumption and emissions. Jaguar will be replacing the AJ-126 with an all new Ingenium turbocharged inline-6 engine. 2013–present Jaguar F-Type V6 / V6 S / 400 Sport / R-Dynamic 2013–2019 Jaguar XJ Portfolio 2013–2015 Jaguar XF Portfolio 2015–2020 Jaguar XF 35t / S 2017–2020 Jaguar XF Sportbrake S 2015–2019 Jaguar XE 35t / S 2014–2019 Range Rover (L405) 2014–2019 Range Rover Sport (L494) 2014–2016 Land Rover Discovery 4 / LR4 (L319) 2017–2020 Land Rover Discovery Si6 (L462) 2016–2020 Jaguar F-Pace 35t / S 2018–2020 Range Rover Velar P340 / P380 See also Jaguar AJ6 engine Jaguar AJ-V6 engine Jaguar V12 engine References AJ-V8 Gasoline engines by model V8 engines
