Air compressor booster intake can meet the needs of heavy-duty vehicles
Advantages of air compressor booster air intake: When the air compressor adopts natural air intake, the gas pressure at the inlet of the cylinder head is negative, and the air compressor air intake is insufficient, which makes the charging efficiency low, generally the best In the case of only about 60% (exhaust pressure 0.8MPa); when the air compressor uses pressurized intake air, the pressure at the inlet of the cylinder head is positive, which increases the air intake of the air compressor, and its charging efficiency Significantly improved, up to 80%. From this point of view, the air compressor adopts the supercharged air intake to be superior to the natural intake air. Under the condition that the air compressor stroke volume is constant, the exhaust air volume can be increased a lot to meet the needs of the heavy-duty vehicle. Disadvantages of air compressor booster air intake: Air compressors have obvious advantages in using supercharged air intake, but there are also disadvantages that need to be overcome. Because the gas temperature of the turbocharger is higher (especially the engine without medium cooling), that is, the gas entering the air compressor is higher than the natural air intake, and the air compressor is compressed and the exhaust temperature is higher. This has a great impact on the life of the air compressor itself and even the performance of the engine. The following analysis is based on the different unloading modes of the air compressor. The unloading of the air compressor means that when the pressure in the car storage tank reaches the set value, the air compressor should stop inflating to the gas storage tank, and the air compressor operates at an empty load. At present, the unloading mode of the vehicle air compressor is generally divided into two types: an air intake unloading type and an exhaust unloading type. The air intake unloading means that a feedback pipeline is arranged in parallel with the exhaust pipe of the air compressor. One end of the pipeline is connected to the gas storage tank, and the other end is connected with a loose pressure valve disposed on the cylinder head of the air compressor. The mechanism is connected, with a pressure regulator in the middle. When the gas pressure in the gas storage tank reaches the set value, the pressure regulator does not pass, and the air compressor inflates into the gas storage tank.
