ANALYSIS OF FUEL VAPORIZATION IN S.I. ENGINE CYLINDER DURING LOW TEMPERATURE CRANKING
In order to improve the starting of a spark ignition engine under low ambient temperatures, several factors influencing starting were studied from the viewpoint of mixture formation in the cylinder during engine cranking. The amount of vaporized fuel in the cylinder was estimated from the cylinder pressure difference between a neat-air cycle and fuel-air cycle under the same cranking conditions. Spark ignition energy was not supplied. Five single-component, three dual-component, and five full boiling range fuels were used in the experiments. Factors influencing mixture temperature in the cylinder, i.e., cranking speed and ignition timing were also studied. As a result, it was confirmed that the occurrence of first fire depends heavily on mixture strength, that is, the amount of fuel vaporized in the cylinder. In addition, an approach to improving cold engine starting with low volatility fuels was discovered.
