摘要： A system for controlling power in a machine includes an interface and a controller configured to receive a signal indicative of a requested hydraulic operation of a hydraulic actuator corresponding to a requested hydraulic power level. The controller is further configured to receive a signal indicative of a requested electric operation of the electric actuator corresponding to a requested electric power level. The controller is also configured to provide a signal for supplying electric power to the electric actuator less than the requested electric power level based on an electric power output ratio, and provide a signal for supplying hydraulic power to the hydraulic actuator less than the requested hydraulic power level based on a hydraulic power output ratio. At least one of the electric power output ratio and the hydraulic power output ratio is adjustable via the interface.

摘要： A system for controlling power in a machine includes a controller. The controller is configured to receive request signals indicative of requested operation of at least one of an electric device and a hydraulic device. The controller is further configured to determine a requested level of power required to meet the requested operation and determine an ability of the engine to supply the requested level of power. The controller is further configured to provide control signals to the at least one device to either supply power to the engine or receive power from the engine based on the ability of the engine to supply the requested level of power. The controller is also configured to provide control signals to the engine to control speed and output of the engine, wherein the control signals provided to the engine and the at least one device result in operation of the engine within a speed range of a target engine speed.

摘要： A method of operating a combustion engine including causing an intake stroke in a first cylinder, causing a compression stroke in the first cylinder thereby creating pressurized fluid and releasing pressurized fluid from the first cylinder. The method further includes cooling the released fluid, directing the cooled fluid into a second cylinder over a first period of time and injecting fuel into the second cylinder over a second period of time whereby the first and second periods of time at least partially overlap.
