基于金属片积碳试验的汽油清洁剂性能测试

为研究汽油清洁剂对发动机喷油器头部积碳的影响规律,以聚醚胺、聚异丁烯胺和曼尼希碱3种汽油清洁剂为研究对象,在金属片积碳试验台架上试验研究其对汽油积碳的影响.对3种汽油清洁剂进行热重测试,在试验台架上对无清洁剂汽油和聚醚胺、聚异丁烯胺、曼尼希碱的质量分数分别为0.5‰和1.0‰的清洁剂汽油进行9个温度条件下的积碳试验,并...

Performance test of gasoline cleaner based on metal sheet deposition test bench

In order to study the influence of gasoline cleaners on the carbon deposit in the engine injector head,three gasoline cleaners,polyether amine,polyisobutylene amine and Mannich base,are used as the research objects and tested on a metal sheet carbon deposit test bench to study their effect on deposits.The thermogravimetric test is carried out on the three gasoline cleaners,and gasoline without additives and gasolines with 3 different gasoline cleaners added in 2 different mass concentrations are tested for deposition under 9 temperature conditions on the test bench.The results show that thermal stability has an important influence on the cleaning effect of gasoline cleaners;the inhibitory effect of polyether amine,polyisobutylene amine and Mannich base on gasoline deposition is closely related to temperature;the concentration of the gasoline cleaners has a great impact on the cleaning performance,when the temperature exceeds 180℃,adding high concentration of polyether amine or polyisobutylene amine will increase the deposit on the metal sheet.
