<p>The invention discloses a method of powering in super expansion rate and exhausting in low temperature for internal combustion engine and a reciprocating internal combustion engine. The characteristic of the method is that: the compression value of the pressurized intake volume is in the range of 2.5Mpa to 5Mpa for achieving the requested power, hence the combustion temperature and the pressure are improved. The working volume of the cylinder is designed by the super expansion rate depending to the effective pressure for working. By means of the heat energy of combustion gas produced in constant volume power stroke, the super expansion rate is reached in constant volume power stroke, the super expansion rate is reached in thermal insulation condition. The characteristic of the engine is that: a reciprocating cycle of piston is a working cycle. In theory, a working cycle includes an intake-combustion stroke from top dead center to bottom dead center and an exhausting stroke from bottom dead center to top dead center. Therefore, in the engine of the invention, the heat efficiency is remarkably improved, the fuel is economized and the emission is depressed.</p> |
