Abstract: Customized hardware provides a generator sizing interface to the user for selecting individual loads that may be present at a particular facility of building. The hardware and/or generator sizing interface receives one or more load selections from the user and, in response, generates a single line diagram or a one line diagram for power flow analysis based on the load selections. The hardware and/or generator sizing interface accesses a database for power requirements for the load selections of the diagram. A List of potential generators or an optimal generator is identified based at least in part on the power requirement of the load selections.

Abstract: A multi cylinder homogeneous charge compression ignition engine includes actuators and an engine controller configured to reduce variations in combustion phasing and/or combustion energy release among the different engine cylinders. By sensing both the phasing and magnitude of the combustion energy release, the engine controller generates control signals to combustion phase controllers and combustion energy release controllers for the engine cylinders. The control signals may be different from one another to reduce variations across the group of engine cylinders. A combustion energy release controller may be a direct injection fuel injector, and the combustion phase controller may be a variable intake valve actuator. Reducing variations in these aspects of the combustion events, allows the engine to operate at higher speeds and loads.

Abstract: A homogenous charge compression ignition engine is operated by compressing a charge mixture of air, exhaust and fuel in a combustion chamber to an autoignition condition of the fuel. The engine may facilitate a transition from a first combination of speed and load to a second combination of speed and load by changing the charge mixture and compression ratio. This may be accomplished in a consecutive engine cycle by adjusting both a fuel injector control signal and a variable valve control signal away from a nominal variable valve control signal. Thereafter in one or more subsequent engine cycles, more sluggish adjustments are made to at least one of a geometric compression ratio control signal and an exhaust gas recirculation control signal to allow the variable valve control signal to be readjusted back toward its nominal variable valve control signal setting.

Abstract: A method of initially operating an internal combustion engine including operating the engine in a start-up mode is provided. The start-up mode includes injecting at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots. An engine is provided including an electronic controller with a computer readable medium having a control algorithm recorded thereon, the control algorithm including means for commanding injection of a main fuel shot and at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots.

Abstract: A method for detecting and controlling the position of a valve actuator is provided. The method includes applying a plurality of signals of different duration and/or magnitude to the valve actuator and measuring a signal from the valve actuator. This signal from the valve actuator is indicative of valve movement for each of the plurality of applied signals. The method further includes adjusting an injection signal to the valve actuator based at least from the measured signals from the valve actuator. This disclosure also applies this method to a solenoid actuator of a fuel injector.
