Top 10 Questions for Diesel Tractor Engine Mechanic Interview

1. What are the main components of a diesel tractor engine?

The main components of a diesel tractor engine are:

• Engine block
• Cylinder head
• Pistons
• Connecting rods
• Crankshaft
• Camshaft
• Valves
• Fuel system
• Air intake system
• Exhaust system
• Cooling system
• Lubrication system

2. How does a diesel tractor engine operate?

Combustion Cycle

• Intake stroke: The intake valve opens, and the piston moves down, drawing air into the cylinder.
• Compression stroke: The intake valve closes, and the piston moves up, compressing the air.
• Injection stroke: The fuel injector sprays diesel fuel into the compressed air.
• Power stroke: The fuel ignites, and the expanding gases drive the piston down.
• Exhaust stroke: The exhaust valve opens, and the piston moves up, pushing the exhaust gases out of the cylinder.

Mechanical Operation

• The crankshaft converts the linear motion of the pistons into rotary motion.
• The camshaft operates the valves.
• The fuel system delivers fuel to the injectors.
• The air intake system supplies air to the cylinders.
• The exhaust system removes exhaust gases from the cylinders.
• The cooling system prevents the engine from overheating.
• The lubrication system reduces friction between moving parts.
