Abstract
PURPOSE: To improve ignition performance, by firstly injecting light oil into a combustion chamber near the top dead center of compression stroke to ignite the light oil and then injecting a large quantity of ethanol into the light oil ignition area to cause the diesel combustion of the ethanol.
CONSTITUTION: At the stroke of compression, a piston 1 goes up, the temperature of spontaneous ignition falls and the temperature of air rises. When the temperature of a previous combustion chamber 6 exceeds the that of spontaneous ignition near the end of the dead center of the compression stroke, a small quantity of light oil is injected into the chamber 6 through an injection valve 10 to ignite a mixture of medium concentration between excessive thickness and excessive thinness. A large quantity of ethanol is injected from an ethanol injection nozzle 12 toward the combustion flame of the light oil and right then burned. The pressure of the previous combustion chamber 6 sharply rises due to the flame of the thanol and exceeds that of a main combustion chamber 4. The nucleus of the flame in the previous combustion chamber 6 rushes together with unburned constituents and an excessively thick mixture into the main combustion chamber 4 through an injection port 5. The exces sively thick mixture is mixed with an excessively thin mixture in the chamber 4 so that the excessively thick mixture is diluted.
