Problems solved by technology

[0002] When the existing single-cylinder diesel engine is accelerating freely, that is, when accelerating from idle speed to the rated speed, because the speed control lever is in rigid contact with the fuel supply rack of the fuel injection pump, the fuel injection volume suddenly exceeds the air intake volume, causing the fuel mixture to lose balance. Lead to imperfect combustion and black smoke, thus affecting the comprehensive indicators of diesel engine smoke and economy

Abstract

This invention relates to a single-cylinder diesel engine speed adjusting mechanism and single-cylinder diesel engine with the speed adjusting mechanism. The mechanism has speed adjusting level and elastic buffer mechanism, they are fixed connected, the level is elastic connected to oil supply gear rack of oil supply pump through the elastic buffer mechanism. Elastic buffer is used in the speed adjusting mechanism in this invention. Injection pump can provides uniform oil when the diesel engine freely accelerates through the new design of existing single-cylinder diesel engine speed adjusting level, the mixing ratio of fuel and air is compatible. The burning of fuel of the single-cylinder is full, limit of smoke and economical efficiency can be improved effectively when the diesel engine at freely accelerating stage.

Description

technical field [0001] The invention relates to the technical field of single-cylinder diesel engines, in particular to a single-cylinder diesel engine speed regulating mechanism and a single-cylinder diesel engine equipped with the speed regulating mechanism. Background technique [0002] When the existing single-cylinder diesel engine is accelerating freely, that is, when accelerating from idle speed to the rated speed, because the speed control lever is in rigid contact with the fuel supply rack of the fuel injection pump, the fuel injection volume suddenly exceeds the air intake volume, causing the fuel mixture to lose balance. It leads to imperfect combustion and black smoke, which affects the comprehensive indicators such as the smoke degree and economy of the diesel engine. Contents of the invention [0003] In order to overcome the deficiencies of the existing single-cylinder diesel engine speed control mechanism, the purpose of the present invention is to provide ...
