A great number of dynamometer experiments are carried out to investigate the effects of structure characteristics of the injector, configuration of combustion chamber, design of the bypass valve and fuel injection phasing on the performance, emission, fuel consumption of the engine during light load operating conditions. After a final optimization and other practical considerations, the control MAPs for the two-stroke DISI prototype engine are obtained. The torque performance, fuel consumption and emission economy of the engine is tested and compared with those of the original carbureted engine.
