The analysis of speed governor´s performance and design of fuel corrector of single cylinder diesel engine for mobile using

According to the requirements of national standards for mobile use diesel engine, this paper analyzed the characteristics of speed governor of the second-generation 186FA single-cylinder direct injection diesel engine. Using Pro/E software to establish the three-dimensional model of speed governor ball, the force of the speed governor was analyzed and calculated, and the force diagram of the diesel engine´s governor was obtained. In order to calculate the speed governing rate of the diesel engine, it showed a method to determine the position of governor speed control lever by loop fuel supply of the maximum speed non-load condition, which was calculated by mechanical loss. On this basis, it showed the design and calculation method for single-cylinder diesel engine oil corrector. By using this method it can accurately draw the value of correction stroke, starting enriched stroke, the maximum force of correcting spring, the pre-tightening force of starting spring.
