Internal cooling of internal combustion engine

Abstract

The invention relates to internal cooling, which is a cooling method adopted by an adiabatic internal combustion engine and an opaque and adiabatic internal combustion engine. The internal cooling method aims to solve the technical problem that the adiabatic internal combustion engine cannot be normally used due to over high temperature. The internal cooling method adopts the technical scheme that water mist is sprayed into an air inlet manifold and fully mixed with air, so as to form mixed gas; the mixed gas passes through four strokes of an internal combustion engine and can cool and reduce the working temperature and the air exhaust temperature; and the water content of the mixed gas cannot exceed a certain range, and the normal combustion of fuel oil cannot be influenced within the range.

Description

Technical field: [0001] internal combustion engine. Background technique: [0002] The thermal efficiency of the internal combustion engine is low, such as the thermal efficiency of a gasoline internal combustion engine is 15-25%, and the thermal efficiency of a diesel internal combustion engine is 25-40%. By doubling the thermal efficiency of internal combustion engines on average, the world will greatly reduce fuel consumption and power costs, save a lot of energy, reduce global warming, and reduce carbon dioxide emissions and air pollution. To double the thermal efficiency, two measures must be taken at the same time. One is to use high-coefficient thermal and optical insulation materials to minimize heat transfer losses, and the other is to use internal cooling methods to reduce the operating temperature to within the normal range. Invention content: [0003] The technical problem to be solved by the present invention is: reduce the working temperature of the adiabati...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: reduce the working temperature of the adiabatic internal combustion engine and the adiabatic and light-insulated internal combustion engine, and reduce the working temperature to be lower than the temperature resistance limit of the manufacturing material. At present, the current adiabatic internal combustion engine can be used normally only when the internal cooling lowers the working temperature ;Reduce the suction temperature of the adiabatic internal combustion engine, thereby increasing the cylinder charge to increase the power; reduce the working stroke temperature of the adiabatic internal combustion engine, thereby reducing the rapid loss of the piston at super high temperature; reduce the exhaust temperature of the adiabatic internal combustion engine, thereby improving thermal efficiency and reducing heat loss
