Analysis of the impact of using additional injectors in the intake manifold on utility and ecological parameters enforced ignition engine

The article presents the results of comparative research on the utility and ecological parameters of the FSO 1.6 GSi engine, which are the effect of using additional injectors in the intake manifold. In the future, these injectors will be responsible for supplying the engine with alternative fuels. Engine parameters such as: cylinder filling factor, torque, unit fuel consumption and exhaust composition were analyzed. The tests were carried out with both standard and modified collector, in which additional injectors were installed.
