Problems solved by technology

[0002] The working principle of the exhaust gas turbocharger is to use the exhaust gas emitted by the engine to drive the exhaust gas turbine to rotate, and then the exhaust gas turbine drives the coaxially connected compressor turbine to rotate, and then pressurizes the air and sends it into the engine; but when the engine speed is relatively high When it is low, the displacement is small, and it cannot push the exhaust gas turbine to reach the working speed, so the turbocharger cannot work when the engine speed is low

Abstract

The invention discloses a method for assisting engine air intake by recovering braking force. When the driver brakes the brake pedal, the hydraulic brake mechanism 11 is driven to work, and the brake disc 111 will drive the driving shaft 122 to rotate. Since the hydraulic drive cylinder 123 The oil circuit of the hydraulic brake mechanism 11 is connected in series, so that the oil inlet and outlet of the hydraulic drive cylinder 123 are synchronized with the oil inlet and outlet of the hydraulic brake mechanism 11. When braking, the oil will push The hydraulic brake mechanism 11 performs the braking action, and the hydraulic drive cylinder 123 also presses the driven shaft 124 and the drive shaft 122 to achieve power connection. When the brake is released, the oil circuit of the hydraulic drive cylinder and the oil of the hydraulic brake mechanism The road is connected in series; the invention can make the turbocharger intervene in the work when the engine speed is low, improve the output power of the engine, and reduce the turbo hysteresis phenomenon of the turbocharger.

Description

technical field [0001] The present invention relates to a method for assisting engine air intake with regenerative braking force. Background technique [0002] The working principle of the exhaust gas turbocharger is to use the exhaust gas emitted by the engine to drive the exhaust gas turbine to rotate, and then the exhaust gas turbine drives the coaxially connected compressor turbine to rotate, and then pressurizes the air and sends it into the engine; but when the engine speed is relatively high When it is low, the displacement is small, and the exhaust gas turbine cannot be driven to reach the working speed, so the turbocharger cannot work when the engine speed is low. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages mentioned above, and provide a method for assisting engine air intake by recovering braking force. [0004] To achieve the above object, the specific scheme of the present invention is as follows: ...
