Performance, Fuel Economy, and Emissions Optimization for a 2.2L Multipoint Fuel Injection Gasoline Engine 2002-01-2845
Future boundary conditions for vehicle engine development will be very complex since they are “functions” of parameters that are difficult to predict: increasingly stringent legislation, changing consumer demand, and availability of resources. The main development goals for passenger cars today are the enhancement of performance and reduction of fuel consumption and cost while facing future emission standards. In China for example, drastic changes in emission regulation have forced the automotive industry to speed up the development processes and shorten the product life cycles.
In this respect, the Mianyang Xinchen Engine Co. Ltd, part of Brilliance Group, Mianyang China and FEV Motorentechnik, Aachen Germany conducted a joint project to study Mianyang's 2.2L, 2-valve, multipoint fuel injection (MPI) gasoline engine. The purpose of the project was to enhance the performance of the engine with minimum changes to existing engine hardware, yet maintain low fuel consumption and exhaust emissions. Extensive experimental studies and theoretical analyses were applied. This paper describes the development targets, the steps to get there, and the tools applied in order to reduce development time.
