Diversion three-dimensional cooling device of single-cylinder vertical air-cooling diesel engine

Abstract

The invention discloses a diversion three-dimensional cooling device of a single-cylinder vertical air-cooling diesel engine. The diversion three-dimensional cooling device is provided with a unique forced air cooling system which can be used for conducting forced air cooling on an air cylinder sleeve, an air cylinder cover, engine oil, an engine body shell and a silencer of the vertical air-cooling diesel engine and improve the overall heat dissipating performance of the diesel engine. Compared with the prior art, a cooling system of the diversion three-dimensional cooling device can make the temperature of the engine oil of the diesel engine to be reduced by 24-29 DEG C under the same environment temperature condition, and a technical effect which cannot be foreseen by technicians in the field can be achieved on the cooling effect of the diesel engine.

Description

Technical field: [0001] The invention relates to a vertical single-cylinder air-cooled diesel engine, in particular to a cooling system for a vertical single-cylinder air-cooled diesel engine. Background technique: [0002] The air-cooled diesel engine cooling system directly affects the working temperature of the diesel engine, and the level of engine temperature directly affects the technical performance indicators of the diesel engine. It is necessary to give full play to the efficiency of the diesel engine, prolong the service life of the engine, reduce the fuel consumption rate, reduce emissions, and increase power. output is extremely important. [0003] The diesel engine is operated at a very high working cycle temperature. The temperature at the end of combustion can reach 1700-2000°C, or even higher. The temperature of the cylinder wall is 200-300°C, and the temperature of the inner wall of the cylinder head and the top of the piston is 300-400°C. °C, the temperatu...

Problems solved by technology

[0009] ③Sealing effect: there is a certain gap between the cylinder and the piston of the engine, the piston ring and the ring groove, the valve and the valve seat, so as to ensure that the movement between the fittings will not be stuck, but these gaps are easy to cause the combustion chamber The mixed gas escapes into the crankcase, which not only accelerates the deterioration of the lubricating oil, but also reduces the cylinder pressure and the output power of the engine.

Too high or too low oil pressure will cause poor lubrication and cooling of matching parts, such as main bearing bushes, connecting rod bushes, bearings and copper sleeves, resulting in severe wear, even burnout and more serious accidents.
