Technical note: Analytical study to minimise the heat losses From a propane powered 4-stroke spark ignition engine

摘要

The alarming rate at which the Earth's atmosphere is getting polluted, the increased impact of global warming on the weather conditions on Earth and the stringent anti-pollution laws imposed in certain countries are among the main reasons for the search for alternatives to gasoline. Liquefied Petroleum Gas (LPG) (mainly propane) is among the many alternatives proposed to replace gasoline in the short term due to its excellent characteristics as a fuel for spark ignition (SI) engines. This paper presents a discussion on the parameters that affect the engine's heat losses mainly during power stroke, with suggestions to minimise it.
