现代车用燃料以汽油和柴油为主,它们在燃烧过程中的生成物主要是二氧化碳、水、碳氢化合物及一氧化碳。当发动机的工作不正常时,其所排气体的颜色及温度就会发生变化。笔者通过实践,摸索了一些根据这些变化推断故障原因及相应的对策措施。 排气烟色分析及对策 排气出现白色烟雾 汽、柴油车起动后排气呈白色烟雾,多为燃 Modern car fuel to gasoline and diesel-based, their products generated in the combustion process is mainly carbon dioxide, water, hydrocarbons and carbon monoxide. When the engine is not working properly, the color and temperature of the exhaust gas will change. Through practice, I have explored some of the causes of inference based on these changes and the corresponding countermeasures. Exhaust smoke color analysis and countermeasures Exhaust white smoke vapor, diesel car exhaust was white smoke, mostly burning
