Abstract

The invention provides a sequential supercharged diesel engine hydraulic device based on waste gas utilization and a control method. The sequential supercharged diesel engine hydraulic device comprises a fuel feed pump, a hydraulic pump, a speed reducing mechanism, a controlling supercharger, a controlled supercharger, a first hydraulic motor, a second hydraulic motor and a diesel engine. The fuel feed pump communicates with the hydraulic pump; the hydraulic pump and the speed reducing mechanism are connected and then mounted on the controlling supercharger; the first hydraulic motor is disposed on the controlled supercharger; the second hydraulic motor is mounted at the front end of an auxiliary propulsion force crankshaft of the diesel engine; a first bypass valve and a second bypass valve are arranged in the position of the first hydraulic motor and the position of the second hydraulic motor in a parallel connection mode correspondingly; a control unit is further disposed on a fuel pipe between the hydraulic pump and the first hydraulic motor; and the second hydraulic motor and the second bypass valve are connected in parallel and then connected with the control unit and the hydraulic pump sequentially through pipelines. By means of the sequential supercharged diesel engine hydraulic device based on waste gas utilization and the control method, auxiliary propulsion force can be provided for the diesel engine, and the utilization ratio of waste gas energy is further increased.

Description

technical field [0001] The present invention relates to a hydraulic device, in particular to a sequential supercharging diesel engine hydraulic device and control method based on exhaust gas utilization, especially suitable for the controlled supercharger switching process of a sequential supercharging diesel engine and diesel engine 2TC (two turbochargers working ) working condition. Background technique [0002] The Sequential Turbo Charging (STC) system is referred to as the STC system. It consists of two or more turbochargers connected in parallel to form a supercharging system. With the increase of the auxiliary propulsive speed and load of the supercharged diesel engine, they are put into operation sequentially. When the speed or load is lower than a certain set value, cut off the exhaust gas of one or several turbocharger turbines and the air supply of the compressor, so that the exhaust gas flows through the working turbocharger turbines concentratedly, increasing th...
