Auto Air Compressor Energy-Saving Booster Control System

Abstract

The invention discloses an energy-saving pressurization control system of an automobile air compressor. The energy-saving pressurization control system of the automobile air compressor comprises an air compressor pressurizer, an intercooler, a turbocharger, an air compressor, an air dyer and an exhaust brake valve, wherein the air outlet of the intercooler is connected with an engine intake manifold; the engine intake manifold is connected with the exhaust brake valve; the exhaust brake valve is connected with the air inlet of the air compressor through an air tank; the air outlet of the air compressor pressurizer is connected with the air inlet of the air compressor; the natural air inlet of the air compressor pressurizer is connected with an air filter; another air outlet branch of the intercooler is connected with a pressurization air inlet of the air compressor pressurizer; the air inlet of the intercooler is connected with the air outlet of the turbocharger; one control port of the air compressor pressurizer is connected with the air inlet of the air dryer; another control port of the air compressor pressurizer is connected with the air inlet of the exhaust brake valve; the exhaust brake valve is connected with the air tank through a switching valve; and the air outlet of the air dryer is connected with the air inlet of the air tank. When the exhaust brake valve is closed, control pressure from the air dryer is automatically cut off. No matter inflation or unloading, air is fetched from the rear of the air filter by the air compressor, therefore, the hidden danger that the air compressor is inflated not enough is avoided.

Description

technical field [0001] The invention relates to a gas booster device, in particular to an energy-saving booster control system for an air compressor for automobiles, and belongs to the technical field of air compressors for automobiles. Background technique [0002] With the development of automobile technology and the increasing safety requirements of users, the braking system has become more and more perfect, the structure has become more and more complex, and the proportion of tractors and engineering vehicles with huge gas consumption has increased significantly. Moreover, the wide application of comfort devices such as air-suspended axles, air-suspended cabs and seats has also greatly increased the amount of air used. As a result, the air supply volume of traditional air compressors is far from meeting the air demand, resulting in a load rate that seriously exceeds the design requirements, a significant increase in failure rate, serious wear and tear, and a shortened se...

Problems solved by technology

Moreover, the wide application of comfort devices such as air-suspension axles, air-suspension cabs and seats has also greatly increased the amount of air used

As a result, the air supply volume of traditional air compressors is far from meeting the air demand, resulting in a load rate that seriously exceeds the design requirements, a sharp increase in failure rates, severe wear, and reduced service life.

The resulting oil leakage and carbon deposits have a serious impact on the safety and service life of the brake system

[0003] In order to solve the above problems, some engine manufacturers switch to double-cylinder air compressors to increase the air output, but problems also follow: 1. Increased costs; 2. Increased energy consumption; 3. Installation problems: switch to double-cylinder air compressors The overall design of the engine must be changed to re-match the transmission power, etc.

4. The phenomenon of oil leakage still exists

[0005] Although the air compressor device for the engine can provide a large displacement of air without enlarging the bore of the piston or increasing the rotating speed, it cannot flexibly adjust whether to supply supercharged intake air between zero load and full load. The compressor has been consuming the compressed air provided by the turbocharger to the engine, reducing engine power and increasing fuel consumption
