How Does a Diesel Engine Work?

Step 1: Air Intake

The process begins with air intake. Air is drawn through the air filter into the engine's cylinders. Diesel engines differ from gasoline engines in that they do not use spark plugs for ignition.

Step 2: Compression

After air enters the cylinders, the piston compresses it to a much higher pressure than in gasoline engines. This high compression ratio is a critical difference between diesel and gasoline engines.

Step 3: Fuel Injection

During compression, fuel is injected into the cylinder. The high pressure of the compressed air causes the fuel to atomize and mix with the air, which is then ignited by the heat generated from the compressed air.

Step 4: Power Stroke

The ignition of the fuel-air mixture leads to an explosion that forces the piston downward. This downward motion generates the power in a diesel engine, ultimately driving the vehicle.

Step 5: Exhaust

After the power stroke, the exhaust valves open, allowing burned gases to be expelled from the cylinder. This step clears the way for fresh air to be drawn in for the next cycle of compression.

Conclusion

In summary, a diesel engine operates through a series of steps including air intake, compression, fuel injection, power stroke, and exhaust. Unlike gasoline engines that rely on spark plugs, diesel engines utilize compression to ignite the fuel. This method makes diesel engines more fuel-efficient and powerful compared to their gasoline counterparts.
