The engine parts used in tractors and other farm machinery should operate in unison to avoid the notice of worried farmers. Most farmers use tractors with four-cycle diesel engines that are fuel efficient and capable of heavy-duty work. An understanding of the four cycles of a typical tractor engine aids in repairing parts in the field.
The first cycle in a functioning tractor engine is the intake stroke. This function involves the opening of the intake valve to collect air for combustion. The insertion of air into the cylinder decreases air pressure and allows the piston to sink in preparation for compression.
The compression stroke in a four-cycle diesel engine involves the movement of the piston upward. The motion of this engine part increases pressure in the cylinder and compresses air. The rising pressure in the cylinder increases air temperature to facilitate combustion needed to run tractors.
Most people are familiar with the essential process of combustion in a diesel engine. The piston continues its rise to the top of the cylinder as the fuel injector sprays fuel. The heated air inside of the engine cylinder and the power of the piston's movement ignite the diesel fuel to keep the engine moving.
The final step in the four-cycle diesel engine is the exhaust stroke. The aforementioned piston moves to the top of the cylinder and pushes noxious fumes out of the engine to the exhaust valve. A repair kit may be necessary to fix the exhaust valve to avoid breakdowns while plowing fields.
