What is used to ignite the fuel in diesel engine?

Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark. In a diesel engine, fuel is introduced as the piston approaches the top dead centre of its stroke.

Do spark plugs ignite the fuel?

The spark plug has two primary functions: To ignite the air/fuel mixture. Electrical energy is transmitted through the spark plug, jumping the gap in the plugs firing end if the voltage supplied to the plug is high enough. This electrical spark ignites the gasoline/air mixture in the combustion chamber.

Does a diesel motor 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.

What happens when we use spark plug in diesel engine?

Instead, diesels have a compression ignition and glow plugs that heat the combustion chamber to aid ignition if a diesel engine is cold. 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.”

What ignites the diesel fuel in the combustion chamber of a diesel engine?

air
The diesel internal combustion engine differs from the gasoline powered Otto cycle by using highly compressed hot air to ignite the fuel rather than using a spark plug (compression ignition rather than spark ignition). In the diesel engine, only air is initially introduced into the combustion chamber.

Which of the following ignites diesel fuel in a warm diesel engine glow plugs heat of compression spark plugs a distributor less ignition?

Answer of MCQ 01:- The correct answer is b) Heat of compression. Explanation:- 1) i) Diesel engines work by compressing only the air. ii) This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously.
