When looking for a car that requires high performance, durability and fuel efficiency, diesel engines are often the answer. The question is, why is this so? Especially in Thailand, where the use of diesel-powered pickup trucks is ranked among the most popular in the world. What are the advantages of diesel engines?And if you want to get a diesel engine, which model is the best choice?

What is a diesel engine? How does it work?

A diesel engine, or officially known as a “compression ignition engine” (Compression-Ignition Engine) is an internal combustion engine that uses the principle of compressing air inside the cylinder until it becomes high heat, which is enough to ignite diesel fuel injected into the cylinder without using a spark plug like a gasoline engine. The heat from this compression causes the fuel to ignite itself, resulting in rapid expansion until there is pressure to drive the piston.

This process makesDiesel carshave higher combustion efficiency than gasoline engines because they make full use of the energy in the fuel, resulting in more torque from low rpm. Helps start or load heavy things easier and smoother.

Advantages of diesel engines

Diesel engines not only have different operating principles, but also have many advantages that make them suitable for use in pickup trucks, especially for rugged use. We can summarizeAdvantages of diesel enginesIt is as follows:

Higher combustion efficiency

Diesel enginesuse the process of compressing air until it becomes very hot to ignite the fuel. As a result, more energy can be extracted from the fuel and the car can be driven further with the same amount of fuel.

High torque from low RPM

Another highlight of diesel engines is the “Torque” that can be released from low RPM, allowing heavy loads or towing efficiently without having to accelerate too high. Unlike gasoline engines that tend to have higher torque at higher revs,

Longer lifespan

Diesel engines are often built with stronger parts and require less maintenance than gasoline engines, such as using a high-pressure fuel pump and improved cooling systems, allowing them to withstand heavy use for longer periods of time. This results in a much longer lifespan for diesel engines.

Fuel Safety

Diesel fuel is safer than gasoline because it has a higher flash point, meaning that diesel fuel must be at a higher temperature to ignite easily.

Cheaper fuel prices

When talking aboutthe advantages of diesel engineswe can't not mention this point. Because in many countries, including Thailand, diesel fuel is cheaper than gasoline. Therefore, using diesel engines in the long term can greatly reduce fuel costs. And when combined with higher combustion efficiency, it makesdiesel carsMore value

Heavy duty durability

Since diesel engines are designed to support heavy duty applications such as carrying heavy loads or operating on rough and harsh road conditions, they can perform well even in challenging environments.
