How Diesel Engine Works

How 4 Stroke Diesel Engine Works – In the process of energy formation, actually 4 engines are not both diesel and gasoline engines have the same working principle. That lies in the performance of each component in carrying out its duties.

Diesel engines are motors that are often used as drives and have an internal combustion (combustion engine), which utilizes compression pressure and high temperatures to burn a mixture of air and diesel.

The compression produced in diesel engines is the performance of the compound named piston and its completeness. While the fuel pressure is the result of pumping bosh pump in collaboration with nozzle.

Before learning how diesel engine works, it may be better to know in advance the characteristics possessed by diesel engines, including:

  • Diesel engines use diesel fuel, biosolar, pertadex, and super shells to power them
  • Has a compression ratio greater than gasoline engines, which is about 15:1 to 22:1
  • Does not require spark plugs to perform combustion
  • Torque and power can be achieved at lower rpm than gasoline engines
  • The peak torque produced by diesel engines is higher than that of gasoline engines
  • The sound and vibration in diesel engines is greater than in gasoline engines
  • Diesel engine manufacturing materials are stronger and more robust

How 4 Stroke Diesel Engine Works

As explained above, that diesel engine 4 does not have the same way of working with gasoline engines. Some of the working steps include suction steps, compression steps, combustion and disposal steps. Here’s the explanation.

1. Suction Steps

A suction step is a step of piston movement from the upper dead point (TMA) to the lower dead point (TMB). In this step, the suction valve in the diesel engine will open and suck the air from the outside through the intake (suction channel) into the combustion chamber (cylinder block). While the exhaust valve will close to prevent air from coming out of the sewer (exhouse).

2. Compression Steps

A compression step is a step of piston movement from the bottom dead point (TMB) to the upper dead point (TMA). At this step, the suction valve and exhaust valve will close. Thus, the room temperature on the cylinder block will turn into hot and high pressure.

3. Combustion Process

Before a few seconds of piston step reaches the upper dead point (TMA), the nozzle will emit fuel. Thus, there is a meeting between high-pressure hot air and particles of diesel fuel. And when the piston step is at the top of the upper dead point (TMA), there is combustion that generates power and pushes the piston towards the lower dead point (TMB).

4. Disposal Steps

The exhaust step is the movement of the piston moving from the bottom dead point (TMB) to the upper dead point (TMA). At this exhaust step the suction valve closes, while the exhaust valve will open discarding the remaining combustion gas towards the exhaust channel (exhouse).

Well, that’s the explanation of how the 4 diesel engine doesn’t work. Please also note that the advantages of diesel engines are that the fuel price is cheap, the engine is tough and more durable. While the drawback is that the purchase price is more expensive than gasoline engines, using a large-capacity battery when starting, the sound and vibration produced by the engine is larger, and prone to damage if it runs out of fuel.

Such is the discussion of how the 4 stroke diesel engine works. Hopefully useful.
