How Does the YANMAR 4LHA STP Work?

Understanding how the YANMAR 4LHA STP works can be simplified into a few key steps:

1. Air and Fuel Intake: The engine draws in air and mixes it with diesel fuel. This mixture is essential for the engine to create power.

2. Combustion: Inside the engine, the air-fuel mixture is compressed and ignited. This creates a small explosion that pushes the engine's pistons down.

3. Power Generation: As the pistons move, they turn the crankshaft, which is connected to the boat's propeller. This movement generates thrust, propelling the boat forward.

4. Exhaust: After the combustion process, the engine expels leftover gases through the exhaust system, allowing the engine to continue running efficiently.
