Oil feeder of single-cylinder air-cooling diesel engine

Abstract

The invention discloses an oil feeder of a single-cylinder air-cooling diesel engine, which comprises an oil injection pump and an oil feed cam matched with the oil injection pump, wherein the oil injection pump comprises a plunger, a plunger matching part, an oil outlet valve matching part, an oil outlet valve core, an oil control sleeve, a plunger spring and a tappet body; the plunger is communicated with an oil inlet pipe, the tappet body is a roller type tappet body, and the oil feed cam is a compound function cam. The oil feeder of the single-cylinder air-cooling diesel engine increases the maximum oil feed rate of the oil feeder, greatly shortens the oil feed duration than before, has the advantages of simple structure and easy implementation, enhances the burning effect of the diesel engine, reduces the oil consumption, decreases the discharge amount of hydrocarbon and carbon monoxide and optimizes the emission index.

Description

technical field [0001] The invention relates to an oil supply device for a single-cylinder air-cooled diesel engine. Background technique [0002] In recent years, with the improvement of the domestic industrial level, the manufacturing quality of diesel engine parts has made great progress, but with the continuous improvement of emission standards and the reduction of oil resources, countries around the world have formulated increasingly stringent targets. Diesel engine emission standards and requirements for economical engines, a large number of studies have shown that in order to fundamentally improve the engine's emission performance and economic performance, it is necessary to improve the combustion process of the engine. There are two main effective measures: one is to increase the fuel injection pressure; the other is to shorten the duration of fuel injection. Due to the limitation of the structure of the engine itself, it is not suitable to improve the combustion pro...

[0002] In recent years, with the improvement of the domestic industrial level, the manufacturing quality of diesel engines has made great progress. However, with the continuous improvement of emission standards and the reduction of oil resources, countries around the world have formulated increasingly stringent targets. Diesel engine emission standards and requirements for economical engines, a large number of studies have shown that in order to fundamentally improve the engine's emission performance and economic performance, it is necessary to improve the combustion process of the engine. There are two main effective measures: one is to increase the fuel injection pressure; the other is to shorten the duration of fuel injection. Due to the limitation of the structure of the engine itself, it is not suitable to improve the combustion process by increasing the fuel injection pressure. The fuel injection duration of traditional engines Longer, the combustion effect of the diesel engine is poor, the fuel consumption is higher, and the emissions of hydrocarbons and carbon monoxide are higher
