What RPM should a diesel cruise at?

How can I get more horsepower out of my Detroit Diesel Series 60?

Install a high flow muffler to allow air to flow out of the engine freely. A ported exhaust manifold can increase the horsepower that your engine achieves by up to 35 percent. Invest in performance fluids for your engine.

Is it OK to rev a diesel engine?

You should therefore allow your engine to rev to the redline at least once every few hundred miles – but only when the oil is warm and you’re on a quiet road. Diesel cars may also have problems with clogged diesel particulate filters (DPFs), which are designed to trap harmful exhaust emissions.

Why does a diesel knock?

Knocking is more or less unavoidable in diesel engines, where fuel is injected into highly compressed air towards the end of the compression stroke. This sudden increase in pressure and temperature causes the distinctive diesel ‘knock’ or ‘clatter’, some of which must be allowed for in the engine design.

Should you drive a diesel hard?

Driving a diesel engine hard will produce less soot per kWh of useful work. Period. Forget about the momentary puff of black smoke you sometimes see as the turbo spools up. It is the net effect that matters.

Why can’t diesels rev high?

Diesel engines never rev as high as petrol engines due to the fact that the piston has to travel further for its full rotation, while a petrol engine uses its shorter stroke to move the piston in quicker bursts, meaning the engine speed can be faster.

Why do diesels 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.

Although it sounds like a drastic measure, the policy may not actually have a very dramatic impact on the industry.

Is it OK to drive a diesel short distances?

Diesel Rule 3: Don’t buy diesels for low mileage or inner city life. Also known as “diesel car city driving”, you want to avoid doing this. Driving at low speeds and short distances clogs up your Diesel Particulate Filter (DPF) quickly.
