Abstract: A power supply system and method includes a power grid input unit and a diesel generator input unit, separately used for supplying an alternating current to a power supply unit. An automatic transfer switch unit is connected to the power grid input unit and the power supply unit or connected to the diesel generator input unit and the power supply unit, which is used for converting the received alternating current into a direct current. A control unit, which is used for monitoring a current load current and current diesel generator power, determines when to turn off a preset number of power supply loads according to a magnitude relationship between the current diesel generator power and the current load power, as well as according to priority levels of current loads. The power supply system is a flexible power supply system and includes the oil engine and a plurality of loads.

Abstract: A hydraulic system of a transmission having a controller and a variable displacement pump. The pump includes an inlet and outlet and is adapted to be driven by a torque-generating mechanism. The system also includes a lube circuit fluidly coupled to the pump. A lube regulator valve is disposed in the lube circuit, such that the lube regulator valve is configured to move between at least a regulated position and an unregulated position. The regulated position corresponds to a regulated pressure in the lube circuit. A pressure switch is fluidly coupled to the lube regulator valve and configured to move between a first position and a second position, where the switch is disposed in electrical communication with the controller. A solenoid is disposed in electrical communication with the controller and is controllably coupled to the pump to alter the displacement of the pump.

Abstract: A lubricating configuration in a two-stroke cycle, opposed-piston engine for a piston wristpin minimizes losses in oil pressure at the wristpin as the piston approaches bottom center and reduces the required oil supply pressure to the engine. The wristpin is constructed to absorb and store oil pressure energy when oil pressure at the wristpin is high, and to release that stored energy to pressurize the oil at the wristpin when connecting rod oil pressure is low.
