How many miles per gallon from a 1500cc diesel engine?
i would guess 32 to 45
This obviously will depend on the mileage per gallon that the engine will consume. Take cars for example. A Bugatti Veyron at full speed covers 3.5 miles per gallon what would give you an autonomy of about 63 miles with an 18 gallon tank. Smart (Mercedes micro car) with Diesel engine makes 48 mpg what would give 864 miles with the 18 ga tank.
Diesel can give much better fuel economy (miles per gallon or kilometers per liter) than petrol but the downside is that diesel engines cost more to manufacture than petrol engines. So a petrol-engined vehicle usually costs less money to buy than a similar make and model that has a diesel engine. The design of a petrol-burning engine is different from that of a diesel engine: a petrol engine burns petrol (called gasoline in the US)…
A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition. Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.
Diesel engines are generally more efficient than gas engines. A Diesel Pickup truck will normally get far more miles per gallon than a gas one and still have equal or greater power available. Plus diesel engines tend to last much longer than gas engines easily running well over 300k miles with little to no issue.
