First of all, we must first understand the difference between a diesel engine and a gasoline engine. First of all, the fuel used by diesel engines is diesel, while the fuel used by gasoline engines is gasoline.
Secondly, since the ignition point of diesel is roughly 220 degrees Celsius, the ignition point of gasoline is above 420 degrees Celsius. Therefore, the diesel engine can use compressed air to increase the temperature of the air. Through the movement of the piston, the diesel and the high-temperature and high-pressure air are mixed together to achieve the effect of spontaneous combustion. However, gasoline cannot be ignited by compressed air. It must be ignited by an additional spark plug to allow the gas to ignite. This situation also indirectly causes diesel engines to be more efficient than gasoline engines. Since the combustion of diesel is controlled by the injectors, if you are worried about the heat generated by too much diesel in the cylinder and the degree of air vibration is too intense, we can completely reduce the injection rate. The injection time or injection volume of the nozzle is less worried about knocking.
Not only from an economic point of view, but from a use point of view, we will still choose diesel engines as the power machinery for ships. This is because the safety, maintenance cost, and power system of diesel engines are better and cheaper than gasoline engines.
First of all, most of the failures of diesel engines are mechanical failures, which are easy to observe and judge, and also convenient to handle; gasoline engines have an additional system that ignites gasoline through electric sparks, which generally involve electrical failures, which are difficult to obtain through direct observation. As a result, it is sometimes more complicated and requires detailed inspection. Secondly, diesel engines have better power than gasoline engines, with lower speed and greater torque. However, diesel engines are noisier and are generally used in heavy construction machinery. The gasoline engine has a relatively high speed. Due to the limitation of the engine's efficiency, its noise will be smaller accordingly, and it is widely used in urban traffic. In addition, although from the outside, gasoline engines tend to be cleaner than diesel engines, but diesel engines have a longer life and are more durable. In contrast, they are more cost-effective. The speed of a diesel engine is lower than that of a gasoline engine, and related parts are not prone to ageing. Compared with a gasoline engine, the degree of wear of the parts will be greatly reduced. Since the engine has no ignition system and few auxiliary electrical appliances, diesel engines are less prone to breakdowns than gasoline engines, which can save us a lot of maintenance costs invisibly.
In terms of safety, diesel is less volatile than gasoline. The ignition point is also 220 degrees Celsius, which is much higher than the usual normal temperature. There will be no fire or safety accidents due to some accidents. Therefore, a diesel engine using diesel is more stable and safer than a gasoline engine using gasoline.
In addition, the diesel engine can have a relatively high torque when the speed is low. In some cases where strong power is required, the performance of the gasoline engine is better. It's just that on flat ground like highways, diesel cars do not perform as well as gasoline cars in terms of speeding up and driving at high speeds.
