A diesel engine is an internal combustion engine, just like a gasoline engine, but the fuel is delivered differently. Fuel is injected directly into the cylinders and mixed with air in a diesel engine. Since the diesel injectors are located in the combustion area of ​​the machine, it is much more complex than the gasoline version.

The most significant advantages of diesel appliances are their high torque and excellent economic performance. The working process of diesel motor has many similarities with gasoline engines, and each working cycle also experiences four strokes of intake, compression, power, and exhaust. 

What Makes Diesel Engines Most Suitable?

Diesel engines have a high compression ratio due to the freedom from deflagration and the need for spontaneous diesel combustion. The thermal efficiency and economy are better than those of the gasoline engine. At the same time, under the same power, the diesel appliances have ample torque and low speed at the maximum capacity, which is suitable for the use of trucks and heavy load vehicles. 

Due to the above characteristics, diesel motors are generally used in large and medium-sized trucks. Traditionally, cars seldom favor diesel apparatus due to their heavyweight vehicles, lower power per liter index than gasoline engines (lower speed), higher noise and vibration, and severe soot and particulate emissions. 

Especially with the new development of small high-speed diesel appliances, several advanced technologies, such as electronically controlled direct injection, common rail, turbocharging, inter-cooling, and other technologies, have been applied to the small diesel motor, so the shortcomings of the original diesel combustion engine have been improved. 

It is a better solution, and the advantages of diesel apparatus in terms of energy-saving and CO2 emissions cannot be replaced by all heat engines, including gasoline engines, and become “green engines.”

Use Of Compression-Ignition Engines In Various Industries

Diesel engines are widely used and occupy a relatively core position in the industry chain to which they belong. 

Diesel apparatus are significantly used as supporting parts in manufacturing large vehicles and the heavy transport industry. For example, high-power and high-speed Ignition Engines are mainly used for heavy-duty vehicles, large passenger cars, construction machinery, ships, and generator sets. Therefore, the development of the diesel appliances industry depends primarily on the market conditions of the relevant end products.

The global agricultural ignition engine market has shown rapid growth. Regarding aero-engine, the engine industry is the core sub-industry of the aviation industry, and the future development prospects are extensive. Based on the above analysis of various fields, we believe that the Ignition Engines will maintain a steady development rate.

Difference Between Diesel Engines And Gasoline Engines

Diesel EnginesGasoline Engines
The diesel motor generally injects diesel directly into the engine cylinder through the fuel injection pump and fuel injection nozzle. It evenly mixes with the compressed air in the cylinder, spontaneously ignites under high temperature and high pressure, and pushes the piston to do work. Each working cycle also undergoes four steps intake, compression, power, and exhaust. This type of engine is usually referred to as a compression ignition engine.The gasoline engine generally injects gasoline into the intake pipe. It mixes it with the air to form an explosive mixture, which enters the cylinder and is ignited by the spark plug to burn and expand to do work
Due to the high compression ratio of diesel motor vehicles, the average fuel consumption is about 30% lower than gasoline engine vehicles, so the fuel economy is better. A 1.7-liter diesel car can save 2 liters of fuel per 100 kilometers compared to a 1.6-liter gasoline car. The weakness of diesel appliances is that the speed is lower than that of gasoline engines (generally, the maximum speed is about 2500-3000 rpm), the quality is large, and the manufacturing and maintenance costs are high (because the fuel injection pump and injector have high processing accuracy). 
Gasoline engine vehicles have the characteristics of high speed (the speed of gasoline engine for cars can be as high as 5000-6000 rpm, and the gasoline engine for trucks can reach about 4000 rpm), lightweight, low noise during operation, easy starting, and low manufacturing and maintenance costs. The disadvantage is that the fuel consumption is higher, and thus the fuel economy is poor.
Its application range is expanding to medium and light trucks. Its application range is from small cars to medium cars and small trucks.
