摘要： A method of reducing carbonaceous deposits on a fuel injector is provided in which a first fuel composition is supplied to the fuel injector in a dual fuel engine, the first fuel composition comprising natural gas fuel and a first percentage of diesel fuel; and a second fuel composition is supplied to the fuel injector in a dual fuel engine, the second fuel composition comprising a second percentage of diesel fuel that is greater than the first percentage of diesel fuel to cause cavitation to occur within the fuel injector, thereby reducing carbonaceous deposits.

摘要： A controller for controlling flow of coolant to one or more components of a vehicle is disclosed. The controller determines respective amounts of heat expected to be rejected by the one or more components of the vehicle in a steady state of operation at current operating conditions of the one or more components, and generates a feedforward flow control signal based at least in part on the determined amounts of heat and a target temperature for the one or more components. The controller generates a controller output signal based at least in part on the feedforward control signal, and provides the controller output signal to the cooling system to control flow of coolant to the one or more components of the vehicle from the cooling system in accordance with the determined amounts of heat expected to be rejected by the one or more components of the vehicle.

摘要： Examples of hybrid powertrain systems are provided herein. The system includes: an engine; a motor/generator (“MG”); a clutch coupled to the engine and the MG; a transmission coupled to the MG; an energy storage system connected to the MG; and a controller coupled to the engine, the MG, the clutch, the transmission and the energy storage system. The controller is configured to initiate an engine stop, allow engine torque and MG torque to reduce to zero or near zero, shift the transmission to a neutral gear, cause the MG to operate in a generator mode, thereby loading the engine to recover kinetic energy from the engine, disengage the clutch to decouple the MG from the engine, increase the speed of the MG to a target speed, and shift the transmission into gear in response to the MG reaching the target speed.

摘要： In a system having a hybrid powertrain having a piston internal combustion engine, and a motor/generator, and the motor generator being coupleable to a clutch and thereby to a gearbox, the engine further being equipped with a valvetrain control system operable to change the engine valve operation between a first mode in which the engine can operate in a conventional internal combustion mode and a second mode in which pumping losses are reduced when the engine is not operating in a conventional internal combustion mode. This allows it to be rotated without generating power, in a hybrid mode, with minimal losses.
