Why are diesel engines more expensive than petrol?

It takes less refining to create diesel which explains its slightly lower cost. Also it is more oily and heavy than petrol for which it evaporates slowly (in fact diesel���s boiling point is higher than water). This coupled with efficient engines gives diesel cars the tag of being more fuel efficient.

Why are diesel engines so expensive?

Generally speaking, it is more complex to shift a diesel engine to newer, stricter emission norms compared to a petrol engine. More pieces of equipment are required in a diesel engine to make the exhaust gases relatively cleaner and hence it is comparatively an expensive shift.

Which is costlier petrol or diesel?

When it comes to cost while buying the car, a diesel variant is relatively more expensive than the petrol variant consisting of the same specifications. The cost difference can range from 50,000 to 1 lakh.

Why diesel is cheaper than petrol Quora?

Diesel contains MORE energy than gasoline and is CHEAPER to manufacture and even handle. It doesn’t vaporize like gasoline. If you took away all the governmental nonsense… diesel is CHEAPER.

Is diesel engine better than petrol?

Diesels are more fuel efficient than petrol engines and emit less CO2, which makes them better for the environment. Diesels produce considerably more torque (pulling power) than their petrol counterparts, which makes them good engines for towing or carrying heavy loads – ie: seven occupants – on a regular basis.

Why diesel is not used in bikes?

Due to the high compression ratio, the diesel engine produces more vibration and noise as compared to the petrol engine. It is not possible for a light vehicle to handle this high vibration and noise. That’s why diesel engines are not used in a motorcycle.

Why are diesel cars cheaper?

So why are diesel cars more expensive to buy? A key factor is that diesel engines usually require extra hardware that petrol ones don’t. To reduce emissions and comply with stricter EU laws, devices such as AdBlue-reliant selective catalytic reduction (SCR) systems often have to be fitted. And these cost money!
