The invention relates to a waste-heat-recovery-assisting efficient internal combustion engine, belonging to waste heat utilization devices for internal combustion engines. The waste-heat-recovery-assisting efficient internal combustion engine comprises a circulating heat-absorbing water pipe which is coiled around a cylinder sleeve of the internal combustion engine fully; an exhaust pipe is arranged at one side of the internal combustion engine and is communicated with a hot air circulation chamber; one end of the circulating heat-absorbing water pipe is connected with a circulating pump through a connecting pipeline; an evaporation chamber is communicated with the outlet of the connecting pipeline; and an impeller is arranged on a crank shaft in an impeller chamber, in which a connecting pipe, a cooling water tank and the circulating pump are communicated with one another. According to the waste-heat-recovery-assisting efficient internal combustion engine provided by the invention, the design is scientific and reasonable, and a high-temperature waste-heat-recovery-assisting device is adopted, so that the utilization ratio of heat energy is greatly increased, the oil consumption is greatly reduced, the exhaust gases and the harmful substances are greatly reduced, and the pollution to the environment is accordingly reduced.
Description
technical field [0001] The invention relates to a waste heat utilization device of an internal combustion engine, in particular to a waste heat recovery boosting high-efficiency internal combustion engine. Background technique [0002] The internal combustion engine is a heat engine that uses the combustion substance generated by fuel combustion as a working medium. It is a power machine that directly converts the heat generated by the combustion of fuel in the cylinder into mechanical energy. From the perspective of the work process of the internal combustion engine, it is the process of converting the high-pressure potential energy generated by fuel combustion into low-pressure potential energy, and the combustion of fuel is finally released in the form of heat. The exhaust gas temperature at the exhaust port is as high as more than 500 degrees, and the exhaust gas is discharged in vain. , From this point of view, the thermal energy utilization rate of the internal combust...
