| Research Abstract |
The developement of alternative fuels for internal combustion engines especially for automotive engines is an urgent need at present. Methanol, which is reported as one of very promising fuels for the car is being tested in many countries such as USA, West Germany, Canada, China, Japan and so forth. Zhejiang University, China, has studied IC engine with alchohol and hydrogen through many years. Gifu University has worked on combustion and temperature measurement of burnt gases with infrared-ray. These experiences of two universities enabled this cooperative research project.
A constant volume combustion chamber is used for the fundamental investigation of the mechanism of combustion of methanol because most of the works in the past were carried out with actual engines. The histories of temperature and pressure which have great influences on knock and exhaust emission were measured at many points in the chamber with variety of conditions.
The peak temperature with methanol whose adiabatic temperature is about 50K or so lower than propane showed no appreciable difference in experiments. This will be caused by the higher flame speed of methanol which resulted in less heat losses during the combustion, though actual engines have turbulence which is different from the one in a constant volume combustion chamber. This also will bring about great difference upon exhaust emission which is left as the future task. It is found that a strong hydrogen flame jet generated by a sub-chamber with volume ratio of less than 1% is very effective to reduce the duration of combustion down to 59.5%.
The investigation of fundamental problems of combustion opened the way to advance the research works on the utilization of methanol and hydrogen as alternative fuels.
