【 摘 要 】

The purpose of the research is to evaluate the operational and ecological parameters of an engine fed by various types of fuel. The test stand constructed for this purpose was prepared to evaluate the engine work indicators for eight different types of motor gasolines from different manufacturers and with different octane number. The tests were performed on a Fiat 170A1 engine. Parameters that were measured directly in the test were: rotational speed, torque, fuel consumption, exhaust gas temperature, run of indicated pressure. The conducted research and comparative analysis of the obtained results confirmed that the type of fuel used does not significantly affect the obtained values of ecological and operating parameters. The higher fuel octane number with the compression ratio used in the research engine did not affect the higher values of the measured parameters.
