It’s a very tricky question as there is no straightforward answer. One has to account for several factors to end the confusion between diesel vs petrol cars. However, knowing the key differences between petrol and diesel cars will make your job easier in selecting the right vehicle for your requirements. And that’s what we are going to address in the video.
By virtue of the combustion process and the overall engine concept, a diesel engine can be up to 40% more efficient than a spark-ignited petrol engine with the same power output, ceteris paribus, particularly with new ‘low’ compression diesels.
The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre). Accounting for the difference in energy density, the overall efficiency of the diesel engine is still some 20% greater than the petrol engine, despite the diesel engine also being heavier.
