WAYS TO IMPROVE OF THE COMBINED METHOD POWER REGULATION OF A SPARK

ABSTRACT

Richok S. Ways to improve of the combined method of power control of a spark ignition engine. // Visnyk of National Transport University. Series «Technical sciences». Scientific and Technical Collection. – Kyiv: National Transport University, 2021. – Issue 3 (50).

The article considers the problem of spark ignition engines low efficiency in low-load and idling modes, as well as one of the ways to solve it by improving the combined method of power control.

The object of research is the influence of the power control method of spark ignition engine on fuel efficiency.

The purpose of research is to improve the combined method of power control of a spark ignition engine.

As a result of familiarization with the previous works which were conducted in this direction, it is established that by deactivating a group of cylinder when engine is idling or at low loads a fuel economy is improving. However, previous works has not considered a possibility of performance improving of engine with electronic control system by filling the deactivated cylinders with exhaust gases of working cylinders, heated air, or a mixture of exhaust gases and air.

KEY WORDS: CYLINDER DISCONNECTION, FUEL ECONOMY, POWER ADJUSTMENT.
