due to the lack of balance shafts but with presumably equal strength as the turbo blocks with balance shafts. B205 and B235 The B205 and B235 engines are an evolution of the B204 and B234 engines. They were introduced in the 1998 Saab 9-5 giving reduced fuel consumption and emissions with improved refinement. The changes included lightweight internal components:lighter valves, softer valve springs, lighter pistons, and lower-drag oil pump. Another development was the introduction of the Trionic 7 torque demand type engine management system. Trionic 7 equipped engines have the black direct ignition casing on top of the engine rather than the red of the Trionic 5. BAIC BAIC offers the Saab H engine in various configurations on several of its models. The B205RGA and B235RGA, 2.0 and 2.3 litre turbo engines are available similar to those used in Saabs. Further BAIC offers a smaller 1.8 litre displacement version named B185RGA. This version was developed to meet requirement for government vehicle with maximum displacement of 1.8 litres. BAIC continued the development of the Saab H engine. In 2015, a B236R prototype was unveiled at the Shanghai Autoshow. This engine design incorporates variable valve timing and an EGR system which allows the engine to comply with Euro 6 emission standards. The BAIC BJ40L is available with a engine named B201R and a engine named B231R. A engine named B205EFA is offered in the Senova X65. The BAIC BJ80 is also available with the B231R engine variant. The B201R and B231R models do not use Saab's Trionic engine management system and direct ignition cassette. Successor to the Saab H-Engine The H-engine ended production with the 1st Generation Saab 9-5 in 2009 when the intellectual property was transferred to BAIC. Starting in 2003 with the 9-3 Sport Sedan, Saab began utilizing the L850 engine Ecotec. Beginning in 2010 with the 2nd generation 9-5, all Saabs utilized the Ecotec. There were some technologies carried over into the Ecotec line from the Saab H-engine, but for the most part there is very little similarity between the two engine families. Saab continued to use its Trionic engine management system with the Ecotec. See also Saab Variable Compression engine Saab V8 References External links Matthew Phenix. "Liquor Does It Quicker".
