Description

technical field [0001] The invention relates to the technical field of an engine, in particular to a novel internal combustion engine. Background technique [0002] As the main power of transportation tools or power generation equipment, engines are widely used in people's daily life and industrial and mining enterprises. The working medium of the current internal combustion engine is mostly the combustion mixture product, that is, the combustible mixture gas is ignited, combusted and exploded in the cylinder to push the piston to do work. And its working process is basically that when the piston moves to the top dead center position, it ignites, the combustible mixture burns and expands, and pushes the engine piston to drive the crankshaft to perform work. At this time, the space volume of the combustion mixture product gas in the engine cylinder is the smallest, only The space of the combustion chamber, so the inside of the engine cylinder has the maximum working pressure...

Problems solved by technology

And its working process is basically that when the piston moves to the top dead center position, it ignites, the combustible mixture burns and expands, and pushes the engine piston to drive the crankshaft to perform work. At this time, the space volume of the combustion mixture product gas in the engine cylinder is the smallest, only The space of the combustion chamber, so the inside of the engine cylinder has the maximum working pressure, and also has the highest temperature, which can reach a high temperature above 2000 degrees Celsius; but when the piston works and moves down for a certain distance, the top of the piston in the engine cylinder The volume of the combustion mixture product also increases due to the downward movement of the piston, which leads to a decrease in the pressure used for work in the engine cylinder. When the piston moves down to the bottom dead center, the pressure of the combustion mixture product in the engine cylinder drops greatly , at this time, the engine discharges the high-temperature exhaust gas produced by burning the combustible mixture, taking away a lot of heat

The engine follows the working principle of the ideal heat engine in the working cycle, and the heat power conversion rate depends on its compression ratio, but from its actual work, their working efficiency is lower than that of the ideal heat engine, because the combustion mixture The expansion rate of the product is limited by the compression ratio produced by the mechanical compression of different engines, so the thermal power conversion rate value is not very high (45% for diesel engine and 35% for gasoline engine), which affects the efficiency of the engine to a certain extent. increased energy consumption

And when the engine is ignited, in addition to the work pressure, it will inevitably produce heat loss. Because the actual working cycle is not an ideal adiabatic cycle, what is used in the internal combustion engine is only the pressure generated by the combustion and expansion of the combustible mixture. , while the lost heat energy is not effectively utilized, a large part of the heat energy is absorbed and dissipated by the cylinder head, cylinder wall, piston and other heat-contacting parts, and the exhaust gas produced by combustion is discharged out of the engine body, which not only increases the energy of the engine Ineffective consumption, but also pollute the environment
