Do Diesel Cars Have Spark Plugs?
No, diesel cars do not require spark plugs, but instead use glow plugs. Diesel cars don’t use spark plugs because of the way the combustion system works in the engine. Glow plugs preheat the cylinders in a diesel engine before fuel compression, ensuring that the energy from the fuel is used for movement rather than just heating the cylinders.

Clean the plugs with a wire brush and carburettor cleaner, scrubbing off carbon deposits. Rinse with water and dry thoroughly with a cloth. Reinstall the spark plugs, ensuring they are tightened securely.
