1. Gasoline parking heater: Gasoline engines generally inject gasoline into the intake pipe and mix it with air to form a combustible mixture, which then enters the cylinder, and is ignited by the spark plug to burn and expand to do work. People usually call it an ignition engine. Diesel engines generally spray diesel directly into the engine cylinder through fuel injection pumps and fuel injection nozzles, and evenly mix with the compressed air in the cylinder, spontaneously ignite under high temperature and high pressure, and push the piston to do work. This type of engine is commonly referred to as a compression ignition engine.
2. Diesel parking heater: The characteristics of traditional diesel engines: better thermal efficiency and economy. Diesel engines use compressed air to increase the air temperature so that the air temperature exceeds the self-ignition point of diesel. Then inject diesel or diesel spray It ignites and burns by itself while mixing with air. Therefore, a diesel engine does not require an ignition system. At the same time, the oil supply system of the diesel engine is relatively simple, so the reliability of the diesel engine is better than that of the gasoline engine.
1) The advantages of diesel engines are large torque and good economic performance. Each working cycle of a diesel engine also goes through four strokes of intake, compression, power, and exhaust. However, since the fuel used in the diesel engine is diesel oil, its viscosity is higher than that of gasoline, it is not easy to evaporate, and its auto-ignition temperature is lower than that of gasoline, so the formation and ignition of combustible mixtures are different from those of gasoline engines.
2) Due to the high working pressure of the diesel engine, the relevant parts are required to have high structural strength and rigidity, so the diesel engine is relatively heavy and bulky; the fuel injection pump and nozzle of the diesel engine require high manufacturing precision, so the cost is high; In addition, the diesel engine works Rough, loud vibration and noise; Diesel oil is not easy to evaporate, it is difficult to start when the car is cold in winter. Due to the above characteristics, diesel engines were generally used in large and medium-sized trucks in the past.
There are many classifications of parking heaters, we need to choose one that suits our model, otherwise it will damage the life of the car. If it is inaccurate, please feel free to contact us, we will help you choose.
