Abstract: An engine includes a housing having a combustion chamber. The engine may also include a fuel injector for supplying fuel directly or indirectly to the combustion chamber. Additionally, the engine may include an engine-lubricant-supply system operable to discharge engine lubricant onto the fuel injector.

Abstract: A control system for controlling a device, the device having at least two functional elements, each functional element being controlled by a control signal, is disclosed in the present disclosure. The control system may include detecting means operatively connected to the device and configured to monitor the operation of the device, and to generate a signal indicative of an operating condition of the device. The control system may also include a control module operatively connected to the at least two functional elements and the detecting means, and configured to switch the two control signals applied to the respective functional elements in response to the signal generated by the detecting means.

Abstract: A high pressure pump for a common rail fuel system avoids torque reversals in its cam shaft by applying a cyclic parasitic load. As the high pressure pump pistons transition from a pumping stroke to a retraction stroke, the cyclic parasitic loading device is loaded to avoid torque reversals in the cam shaft. The cyclic parasitic load device may include a medium pressure pump, such as for supplying medium pressure fuel to a particle trap regeneration device associated with the exhaust after treatment system.

Abstract: A fuel system for an engine is disclosed. The fuel system has a common source of pressurized fuel, at least one injection device, an exhaust treatment device, and a regeneration device. The at least one injection device is configured to inject fuel from the common source into a combustion chamber of the engine. The exhaust treatment device is configured to remove particulate matter from an exhaust flow of the engine. The regeneration device is configured to inject fuel from the common source into at least one of the exhaust treatment device and the exhaust flow.

Abstract: A fluid system for an engine is disclosed. The fluid system has a manifold with a plurality ports, and a retention device configured to constrain the manifold relative to the engine in only a single translational direction. The fluid system also has a plurality of tubes configured to communicate fluid from the ports with the engine and to constrain the manifold in the remaining translational directions.

Abstract: A fuel injector adapter consists of a block defining a pressure communication passage therethrough and an actuation fluid passage. The actuation fluid passage includes three separate branches that open through an outer surface of the block at three separate locations.
