2. The Tractor Engine

What is a Tractor Engine?

A tractor engine is usually a diesel engine, designed to provide high torque and power at low speeds, which is ideal for heavy agricultural work.

How It Works — Step by Step

  1. Air Intake:
    The engine draws in air through an air filter, which cleans dust and dirt particles from the air.

  2. Fuel Injection:
    Diesel fuel is injected directly into the combustion chamber under high pressure.

  3. Compression:
    The piston compresses the air inside the cylinder, heating it up to a very high temperature (diesel engines rely on this heat).

  4. Ignition & Combustion:
    When fuel is injected, it spontaneously ignites because of the hot compressed air, causing combustion.

  5. Power Stroke:
    The explosion pushes the piston down, turning the crankshaft and producing power.

  6. Exhaust Stroke:
    The piston moves back up, pushing out the burnt gases through the exhaust valve.

  7. Cooling & Lubrication:
    The engine is cooled by a radiator system and lubricated by oil to prevent overheating and reduce friction.

Key Points Specific to Tractor Engines

  • High Torque at Low RPM:
    Tractors need a lot of pulling power rather than high speed, so their engines deliver strong torque at low revolutions per minute (RPM).

  • Turbocharging:
    Many tractor engines have turbochargers that force more air into the cylinders, improving power and efficiency.

  • Durability:
    They are built to be rugged and operate for long hours under tough conditions.
