Why Do Diesels Make More Torque?
There are several reasons as to why a diesel engine produces more torque than a gasoline (petrol) engine. The compression ratio of normal diesel engines is higher than that of its gasoline counterparts. It adds to the development of higher peak pressure inside the combustion chamber and, hence, on the crankshaft.

.

Keeping this in view, what makes diesel engines stronger?

A diesel engine uses a much higher compression ratio within the cylinder to heat the air inside. Because the air is so compressed, the engine gets greater efficiency from the fuel. This means a diesel engine is generally 20 per cent more efficient than an equivalent petrol engine.

Similarly, why do inline 6 make more torque? A stroker engine makes more torque by having the expansion of the combustion gases acting on the crankshaft for a longer period of time, due to the longer moment arm of the crank.

Secondly, why do diesels have low horsepower?

A diesel engine usually generates more torque than a petrol engine for a given displacement. This phenomenon is because of higher compression ratio. As air in its pure form needs a high pressure and temperature for its compression, so the horsepower of a diesel engine is low.

Why does a diesel engine last longer?

Diesel engines do last longer than petrol ones. Diesel is a light oil and when burned and used as fuel by the vehicle it lubricates the parts of the engine. This prolongs the life of the engine. This is partly because of the intricate fuel pump which is expensive to repair or replace.

What is the average life of a diesel engine?

The engine life can last between 300-400k miles. Passenger diesel vehicles are not built to the same standard as heavy vehicles!!! :) While no engine will last forever, diesel engines have a distinct advantage in longevity over their gasoline counterparts.

How many miles can a diesel engine last?

A gasoline powered truck can run for 200,000 miles. Conversely, a diesel truck has a longer lifespan and can run for at least 500,000 and as much as 800,000 miles.
