微型车怠速不稳原因与控制措施

微型车怠速不稳与控制措施是本课题研究的重要话题,怠速不稳是常见的故障之一,它有多种表现形式。怠速工况的控制性能反应了一部车的技术性,稳定性,动力性,经济性,排放性等各种技术指标,汽油机的怠速性能主要体现在三个方面:怠速稳定性、怠速排放和怠速油耗。因此探讨怠速不稳与控制措施是一项长期要做的工作,而本文重点讲解了电喷发动机故障诊断与维修的新知识,新技术,具有可借鉴性。对于微型车怠速维修方面具有现实的指导意义。

Abstract： Mini idle instability and control measures are the important topic this subject research, idle instabihty is one o! the com- mon fault. Idling process control performance reflects a car, stability, the technical performance, economy, various technical indexes of e- missions, gasoline engines idling performance mainly in three aspects： idle speed stability, idle emissions and idle oil consumption. Probe into the idle instability and control measures is a long-term of work to do, and this paper emphasized the eft engine fault diagnosis and maintenance of the new knowledge, new technology, with advanced. Idle maintenance for mini realistic guidance significance.
