Diesel air intake and glow plugs

What is the primary function of glow plugs in a diesel engine?

• To ignite the fuel-air mixture.

• To pre-heat the combustion chamber for cold starts.

• To regulate fuel pressure.

• To reduce emissions.

Glow plugs are typically used in:

• Petrol engines.

• Diesel engines.

• Both petrol and diesel engines.

• Neither petrol nor diesel engines.

Where are glow plugs typically located?

• In the intake manifold.

• In the cylinder head, near the combustion chamber.

• In the exhaust manifold.

• In the fuel tank.

What is the purpose of a turbocharger?

• To cool the engine.

• To increase the power output of the engine by forcing more air into the cylinders.

• To reduce emissions.

• To improve fuel economy.

A turbocharger is powered by:

• The engine's crankshaft.

• Exhaust gases.

• The battery.

• The fuel pump.

What is an intercooler used for in a turbocharged engine?

• To cool the engine oil.

• To cool the compressed air from the turbocharger before it enters the engine.

• To reduce exhaust gas temperature.

• To filter impurities from the air.

What is the primary function of a fuel filter?

• To remove contaminants from the fuel.

• To regulate fuel pressure.

• To inject fuel into the cylinders.

• To pump fuel from the tank.

What is the purpose of a sedimenter in a diesel fuel system?

• To separate water and other heavy contaminants from the fuel.

• To filter fine particles from the fuel.

• To regulate fuel flow.

• To pre-heat the fuel.

Where is a sedimenter typically located?

• In the fuel tank.

• Before the fuel filter.

• After the fuel filter.

• In the fuel injection pump.

Why is correct injection pump timing crucial in a diesel engine?

• It ensures proper combustion and optimal engine performance.

• It regulates fuel pressure.

• It controls the glow plugs.

• It reduces emissions.
