Lets Talk About the Differences Between Diesel and Gas Engines – Car Talk Podcast


Both petrol engines and diesel engines use different ignition techniques. Diesel engines do not have spark plugs, so the temperature as well as the compression of the oil determine the rate of combustion. Diesel engines are more fuel-efficient due to this characteristic because petrol engines don’t make air and fumes compress enough to cause combustion. Instead, they use spark plugs.

This difference is not applicable to diesel and petrol engines. But, the throttle body on diesel engines could be an issue. If you press the throttle with greater force it will supply the fuel needed to generate performance. Contrarily, a gasoline engine requires A throttle body that allows more air into the engine to produce more energy.


Braking is an additional area of which diesel and petrol engines are different. In petrol engines, braking takes place by taking the foot off the accelerator. Diesel engines brake during compression stroke. Professionals at diesel engine repair service are usually familiar with the differences.
