Reducing Diesel Knock by Means of Exhaust Gas Recirculation 790268
The different impacts on Diesel knock were investigated. The main parameters were fuel quality, ambient and engine temperature, quantity of fuel injected, compression ratio, and injection timing. One of the most reasonable methods to decrease cold knock is exhaust gas recirculation (EGR). The mechanism of the EGR effect was explained and the limitations of Diesel application of EGR was estimated.
