Abstract: A method of determining the nature of a fault in the operation of a hydraulic fuel injector includes sending an actuation pulse to an actuator of the injector, the actuation pulse being above the minimum drive pulse of the injector. The method also includes analyzing a signal from an accelerometer of the injector to determine if there is a high frequency vibration component subsequent to the end of the activation pulse. The method also includes determining the functionality of a needle control valve of the injector dependent on the outcome of analyzing the signal from the accelerometer.

Abstract: A regulating method for a charged internal combustion engine, wherein an operating point of the compressor is adjusted in a compressor map by a compressor position regulator based on a throttle valve regulation deviation in that both a first manipulated variable for actuating the compressor bypass valve as well as a second manipulated variable for actuating the turbine bypass valve are calculated by the compressor position regulator. The operating point of the compressor is corrected by a correction regulator on the basis of an air mass regulation deviation in that both a first correction variable for correcting the first manipulated variable as well as a second correction variable for correcting the second manipulated variable are calculated by the correction regulator.

Abstract: A cylinder for an internal combustion opposed-piston engine includes a bore, either as part of the cylinder directly or of a liner. The bore has a surface for guiding a pair of pistons disposed for opposing movement in the cylinder. The cylinder bore has three zones of surface finishes: an inner zone extending between and including exhaust and intake ports, where only piston compression rings travel on the bore surface; two instances of an outer zone where only piston oil control rings travel on the bore surface; and two instances of a port zone where both types of rings travel on overlapping paths in the same bore surface portion. Each zone may have a particular surface finish that is tailored to specific requirements including oil control, ring wear, and scuff resistance relevant to the zone.

Abstract: A first switch designates one of energization instruction signals to designate a valve closing detection cylinder. A valve closing detection unit monitors downstream voltages of the fuel injection valves to detect occurrence of an inflection point in change of the downstream voltages and detects valve closing. A second switch designates one of the downstream voltages and designates the valve closing detection cylinder. A stage number designation unit designates a valve closing detection stage number. A valve closing time measuring unit measures a valve closing time, which is from a switching timing at which the energization instruction signal is switched from ON to OFF to a valve closing detection timing of the valve closing, for injection of the valve closing detection stage number of the valve closing detection cylinder. A valve closing time learning unit learns the valve closing time measured by the valve closing time measuring unit.

Abstract: Systems and methods for controlling fuel factions delivered to different cylinders are provided. In one example, a controller is configured to, during a single engine cycle and responsive to a first condition, deliver a lower fraction of a first fuel into a donor cylinder in comparison to a fraction of the first fuel being injected into a non-donor cylinder and deliver a higher fraction of a second fuel into the donor cylinder in comparison to a fraction of the second fuel being injected into the non-donor cylinder.

Abstract: An engine is disclosed having a water cooling system allowing efficient cooling of the exhaust valves to prevent temperature gradients from building in the engine.
