Diesel engines as well as gasoline engines are types of engines that have different ways of working. In Indonesia, most of the passenger cars have a gasoline engine, while commercial vehicles have a diesel engine. All of them have their own advantages and disadvantages. Then, what are the advantages and disadvantages of a diesel engine?
This time we will discuss about this diesel engine, especially regarding its advantages and disadvantages compared to cars that use gasoline engines. The most basic difference from a car that uses a diesel engine and a gasoline engine is the trigger component in the combustion chamber. If the gasoline engine has a trigger combination of spark plugs, air, and fuel. So for cars that use diesel engines this is not the case.
To trigger a diesel engine is to use air pressure. That is, the air enters through the piston and is compressed so that it gets pressure at a certain temperature. And at the same time, fuel is injected into the combustion chamber. The meeting between compressed air and fuel is what triggers the explosion of diesel particles. And in the end can move other components.
Advantages and Disadvantages of Diesel Engines
Thus, the most visible difference between diesel engines and gasoline engines is that diesel engines do not have spark plugs as found in gasoline engines. Here are the advantages and disadvantages of a diesel engine that you can see below:
Advantages of Diesel Engines
Diesel engines are generally produced using stronger materials because diesel engines have higher compression than gasoline engines. The air temperature in the combustion chamber is much hotter.
Diesel engines can produce better torque at lower rpm. As an illustration, a four-cylinder diesel engine produces the same torque as a six-cylinder petrol engine.
Diesel cars use less fuel than gasoline engines. This is because diesel engines have a much higher compression ratio than gasoline engines. And also for the fuel price is relatively cheaper.
Disadvantages of Diesel Engines
His voice is noisy
The sound from the diesel engine itself is very noisy compared to the gasoline engine. This is because most of the sound on a gasoline engine comes from the exhaust system. Meanwhile, the diesel engine comes from the engine itself.
