Diesel engines only: Replace the fuel pump If the culprit of white smoke from the exhaust is because the timing of the injector pump is off, you might simply need to reprogram the computer. If that doesn’t solve the issue, you will most likely have to replace the pump entirely....
If gas going stale in a Toyota PHEV caused problems, it would have come to my notice like the EGR, head gasket, and coolant leak issues. This is not something to worry about. #30 Trollbait, Aug 20, 2023 MyPriusMarvin likes this. ...
There are three main emissions produced by car engines: nitrogen gas (N2), carbon dioxide (CO2) and water vapour (H2O). The catalytic converter however is mostly used to tackle the smaller, more-harmful products that are produced due to the naturally-imperfect combustion process of the IC eng...
Don’t attempt to give the same solution that has seemingly failed to an error code that keeps coming on. There are modern vehicle engines and onboard control systems that can only be easily understood by a professional who understands it. So unless you have the right tools and training to ...
Therefore the last and maximum weighting applied for the five feasible indicators (assets, revenue, greenhouse gas (GHG) emissions, employment, and women participating in management) is 15%, cumulating to a value of 75% of fixed weighting within all indicators; in other words, the individual ...

In some diesels notably those with an EGR Exhaust Gas Recirculation you will often still see a throttle body used. This creates a pressure differential in the intake allowing the exhaust gases to flow better. Diesel engines are made to run lean due to their high compression ratios. The higher...
In engine evolution, EGR technique was firstly adopted in diesel engines in order to limit thermal NO X formation rate by reducing combustion chamber temperature thanks to the dilution of fresh charge with a certain amount of exhaust gas recycled at engine in- ...
废气再循环系统(exhaust gas recirculation,EGR)中冷 器旁通,进气中冷旁通,增压器旁通,排气管优化等 技术 [37].最终 NOx 后处理系统如图 3 所示,采用了双 催化还原催化器 (SCR) 双喷射系统,在常规 SCR 之外, 还采用了一个紧耦合的低起燃温度 SCR(ccLO-SCR). 在 ccLO-SCR 上游不再采用柴油氧化催化器 (...
用汽油机的主流趋势.但是,采用涡轮 增压技术也存在一些问题 [5].由于进气压力和温度的 增加,会导致压缩终了缸内温度升高和压力增加,以 及发动机热负荷增加,使发动机爆震倾向增大.一般 可通过进气中冷,提高燃油辛烷值,降低压缩比,推 迟点火角,加浓混合气,废气再循环(exhaust gas recir- culation, EGR)等技术手段...
