  • Patent number: 10442284
    Abstract: An electro-hydraulic hybrid-power driving system, comprising an engine, a first motor, a second motor, a first planetary gear set, a second planetary gear set, and a hydraulic control shift set that is connected to the engine. The first motor is axially connected to the engine, the second motor is axially connected to the first planetary gear set and the second planetary gear set, and the first planetary gear set is coaxially connected to the second planetary gear set. The hydraulic control shift set includes a first gear and a second gear, a dual wet clutch is disposed between the first gear and the second gear, and the first gear, the second gear, and the dual wet clutch are coaxially connected to the engine. The present invention by disposing a specific electro-hydraulic hybrid-power driving system, different working modes can be implemented according to different requirements.

  • Patent number: 9279352
    Abstract: The invention discloses an integrated SCR metering injection system. The integrated SCR metering injection system includes a metering injection unit and a water heating unit for heating the metering injection unit. The metering injection unit includes a pump body, a membrane pump and a metering valve. The water heating unit includes a water inlet joint, a water inlet pipe, a water outlet pipe and a multi-section water circulation pipe communicated with each other. The water heating unit is used for heating the metering injection unit by heated engine cooling water, so that the heated engine cooling water passes by the metering injection unit directly to improve the recycling rate of energy.
