Why no spark plugs in diesel engine? A diesel engine has no spark plugs. … A spark plug has no use with diesel fuel because there is no need to ‘light’ the diesel fuel. Instead, the glow plug only heats the combustion chamber.” In combination with the piston design, and the heated chamber from the glow plugs, the diesel fuel becomes atomized into a mist.
Why do diesel engines not need spark plugs? Diesel engines, unlike gasoline engines, do not use spark plugs to induce combustion. Instead, they rely solely on compression to raise the temperature of the air to a point where the diesel combusts spontaneously when introduced to the hot, high pressure air. … The glow plug solves this.
Does a diesel engine have spark plugs? Both spark plugs and glow plugs are the ignition source in a combustion engine. So, what’s the difference? The short answer is the type of engine they’re found in. Spark plugs are only found in gasoline engines and glow plugs are in diesel ones.
Did old diesels have spark plugs? Diesels have never had spark plugs – they ignite the fuel by high compression pressures, which result in very high temperatures. Ignition is initiated by injecting a fine mist of fuel into the combustion chamber when the ignition point is reached.

Can you do work on a heat engine?
In thermodynamics and engineering, a heat engine is a system that converts heat to mechanical energy, which can then be used to do mechanical work. It does this by bringing a working substance from a higher state temperature to a lower state temperature. … Also, some energy is unusable because of friction and drag.
Why diesel engines having high compression ratio?
Diesel engines use higher compression ratios than petrol engines, because the lack of a spark plug means that the compression ratio must increase the temperature of the air in the cylinder sufficiently to ignite the diesel using compression ignition.

Why are 2 stroke engines unreliable?
There are four main reasons: Two-stroke engines don’t last nearly as long as four-stroke engines. … Two-stroke engines do not use fuel efficiently, so you would get fewer miles per gallon.
