积炭 [
jī tàn]
carbon deposit
carbon build-up
- 它具有良好的氧化稳定性,不容易生成积炭,使用寿命超过8000个小时。
The excellent oxidative stability and low deposit formation tendency allows for service lives in excess of 8000 hours. - 因混合气过浓、点火系统有故障、发动机内压力损失、冷机等导致的不正常燃烧都会形成气门积炭。
Improper combustion, due to a rich mixture, defective ignition system, loss of compression in the engine, a cold engine, and so forth, will result in carbon deposits on the exhaust valves. - 该试验装置通过对喷油器强化加热、控制喷油器的喷油间隔时间,强化了喷油器结焦积炭的形成条件,缩短了试验时间。
By enhanced heating and controlling the injection interval of the port fuel injector, the formation of carbon deposits (on the )port fuel injector was accelerated and the test time was shortened.
