Operating a diesel engine at a low speed will cause two times the wear on the internal components compared to operating at a normal load. This will raise maintenance costs and shorten engine life.

How much fuel does a semi burn while idling?

Why do truckers stretch their trucks?

This increased radius improves the ability to maximize your weight allowance on the steering axle. The extra frame rail length also allows room to mount generators or tool boxes. For the most part, I've also found a longer wheelbase generally improves resale value as the truck is more versatile in most cases.

What is a truck supposed to idle at?

Typically, engines idle at about 600-800 rpm. Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it's sufficiently warmed up, you might have a problem. High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well.

Why do drivers keep diesel trucks running?

Diesel trucks need a period of time to warm up before they head out on the road pulling several tons of cargo down the interstate at 60+ MPH. Therefore, many truckers will keep the trucks running to keep them warm and to keep oil and coolant circulating the motor.

What happens if you let a diesel idle too long?

Unnecessary idling wastes fuel, causes air pollution and increases engine wear. An idling diesel engine produces much higher emissions than it would while using the same amount of fuel under load. Extended idling causes a build-up of soot inside the engine and results in a puff of black smoke when the engine revs.

Should diesels be driven hard?

A hard driven diesel burns the soot that both hard & soft driving generate but which only hard driving will burn up leaving it to cause damage in a gently driven car. 3. It is about turbo boost. An small engine with lots of boost produces more soot than a bigger less boosted engine producing the same power.
