Why is Diesel More Economical than Petrol?
Did you know that diesel fuel is far more efficient than gasoline? In petrol engines, only 20% of the fuel actually does the work of moving the vehicle and the rest is lost in overcoming friction, noise pollution and in other necessary engine functions. However, diesel engines can reach up to a whopping 40% efficiency or more which makes it super easy to conveniently move heavier vehicles without a lot of fuel consumption. High Compression Ratio Of Diesel Diesel has a higher compression ratio and combustion efficiency which means more power to the vehicle with less fuel consumption and fewer exhaust gases. These make diesel-powered engines quite fuel-efficient as compared to the petrol motors. Why Diesel Engines Are Considered More Economical Than The Petrol Ones? Though diesel and petrol originate from the same source, that is, crude oil yet they have characteristics different from each other. Diesel is denser than petrol and accommodates about more than 15 per cent energy by volume. Therefore, litre for litre, you get more for the same amount spent on diesel.
