摘　　要：以186FA柴油机油量校正器设计为例,分析油量校正器工作原理,指出现有文献资料中油量校正器设计计算存在的缺陷,阐明各设计参数与柴油机速度特性、喷油泵速度特性上性能指标的关系,给出单缸柴油机油量校正器的设计计算方法,使用此方法能准确地得出油量校正行程、起动加浓行程、校正弹簧最大作用力、起动弹簧预紧力的计算值。所研制的带油量校正和起动加浓功能的油量校正器试验表明,186FA柴油机速度特性上的性能指标能完全满足国家标准的相关考核要求,产品已大量生产,为移动用途第二代单缸柴油机研发提供技术保证。Take the oil corrector design of a 186FA diesel engine for example,the working principle of oil corrector is analyzed,and the calculation and design defects in the existing literature are pointed out,meanwhile the relationship between design parameters and performance of speed characteristics for diesel engine is illustrated,and the design and calculation method for single-cylinder diesel engine oil corrector is given.By using this method,the values of correction stroke,starting oil enrichment stroke,the maximum force of correcting spring,and the pre-tightening force of starting spring can be accurately obtained.The test of the developed oil corrector provided with oil correction and starting enrichment shows that the performance of speed characteristics on 186FA diesel engine fully meets the relevant assessment requirements of national standards,and the products are already mass produced,thus providing technical assurance for the development of second-generation single-cylinder diesel engine for mobile application.
