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.
What is used in place of spark plug in diesel engine?
While compression ignition means that diesels don’t require spark plugs, they can come fitted with components called glow plugs. While glow plugs don’t ignite the fuel, they are useful when an engine, or the environment the vehicle is in, is very cold.
How does a diesel engine work without 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.
What is used instead of spark plugs?
Glow plugs are used in diesel-powered internal combustion engines. While spark plugs ignite the engine’s air-fuel mixture whenever the vehicle is running, glow plugs act as a starting aid to get the engine going.
What is the diesel equivalent of spark plugs? – Related Questions
Do all diesel engines have glow plugs?
