Compression Ratio in Automobile Engines: Definition, Formula, Advantages and Applications
How does the compression ratio matter in your vehicle engine? It depends on which engine your vehicles have whether it is Diesel or Petrol Engine. During compression stroke how much air-fuel mixture in Gasoline/Petrol Engine or only air in Diesel Engine, mixture or air molecules compressed in the engine cylinder combustion chamber. Normally the Compression Ratio (CR) of diesel engines has much higher than that of petrol engines. Those vehicles engines higher compression ratio can improve both power and efficiency. Higher compression ratios contribute to the more proper burns of air-fuel, it also increases combustion temperature. The more compressed the mixture the better it burns or ignites, which gets more power and is more efficient, but one drawback is that the engine produced more nitrogen oxide (Nox) emissions. In the simple term to understand, higher combustion temperature and higher compression ratio lead to creates more Nox exhausts emissions produced. In generally ...
