1. Different ignition methods: Diesel engines use a compression stroke to compress the mixture of fuel and air, and the temperature rises to the combustion point for combustion, while gasoline engines use an electronic igniter in the injector to ignite gasoline.
2. Different fuel consumption: Diesel has lower fuel consumption than gasoline. Because the diesel engine has high power, relatively high ignition point and is not easy to volatilize, the fuel consumption of diesel is lower under the same conditions.
3. Different acceleration: The acceleration of a gasoline engine is much faster than that of a diesel engine. This is mainly because the diesel engine does not ignite directly, but needs to compress the mixed gas to reach the ignition point before it can spontaneously ignite. This process will be slower. It also takes a certain amount of time to convert energy, so overall the acceleration will be much slower than that of a gasoline engine.
4. Noise is different: The amount of noise generated by diesel engines and gasoline engines is different during use. The ignition method of diesel engines is different from that of gasoline engines. The special compression ignition ignition method of diesel engines requires A certain amount of power, so the noise is louder than that of a gasoline engine. In addition, during actual driving, the noise produced by diesel engines is greater than that of gasoline engines.
5. Different applicable scope：Diesel is commonly used in high-power machinery such as tractors, heavy-duty trucks, and cargo ships. However, For the engine of the model cars and aircraft, fuel with higher energy and response speed is crucial. Therefore, diesel is generally not used as a conventional fuel for model engines, while gasoline and methanol can be very good choices.
