Abstract: A system and method for injecting fuel into an engine is provided where a low-pressure fuel pump is connected in fluid communication with at least one port fuel injector and a high-pressure fuel pump is connected in fluid communication with at least one direct fuel injector. The port fuel injector is disposed along an intake path of the engine and the direct fuel injector is disposed adjacent a cylinder of the engine. A lost motion lifter selectively couples the high-pressure fuel pump and the engine. A pump deactivation module switches the lost motion lifter to selectively deactivate the high-pressure fuel pump from the engine in response to partial load operation of the engine. The pump deactivation module may additionally switch the port fuel injector to an activated state and the direct fuel injector to a deactivated state.

Abstract: A fuel supply system includes a sub fuel tank, a booster pump, a fuel pipe, a fuel pressure sensor and a controller. The sub fuel tank stores a fuel supplied thereto from a main fuel tank. The booster pump is disposed inside the sub fuel tank. The fuel pipe has a returnless structure and supplies the fuel with a pressure increased by the booster pump to a fuel injection device of an engine. The fuel pressure sensor detects the pressure of the fuel inside the fuel pipe. The controller is configured or programmed to perform a feedback control of the booster pump based on a value of the pressure of the fuel detected by the fuel pressure sensor such that the pressure of the fuel inside the fuel pipe becomes greater than or equal to a first threshold.

Abstract: First and second recessed portions are respectively formed on first and second wall surfaces of a cam chamber, in order that a plunger head and a coil spring would not come in touch with the first and second wall surfaces even in such a virtual situation. In the virtual situation, it is supposed that the plunger head would be separated from a plunger, the plunger head remains in contact with a contact surface of a cam ring so that the plunger head would not move relative to the contact surface, and a cam member would be continuously rotated.

Abstract: In a method for operating an internal combustion engine (10) equipped with a piston pump as a high-pressure pump (18), which is driven by a drive shaft (28) of the engine (10), in which the high-pressure pump (18) delivers fuel from a low-pressure region (16) to a high-pressure side (38) and a quantity control valve (44) sets the quantity of fuel delivered by the high-pressure pump (18), the acoustic emission of the high-pressure pump is reduced by virtue of the fact that the high-pressure pump (18) functions in a two-point operation, alternating between full delivery for individual or successive piston strokes and idle delivery for individual or successive piston strokes and, when the pressure falls below a lower pressure threshold, the full delivery is activated until an upper pressure threshold is reached.

Abstract: In an internal combustion engine, in particular with direct injection, a first fuel pump delivers fuel from a fuel tank to a second fuel pump. This second fuel pump delivers the fuel to a fuel accumulation line. A metering unit is triggered by a control and/or regulating unit and meters the fuel quantity traveling into the inlet of the second fuel pump. In order to simplify the design of the engine and to reduce its cost, the invention proposes that during normal operation, the metering unit is closed when it is without power and that when the control and/or regulating unit is “dead”, the metering unit is without power and the fuel delivery to the metering unit is cut off.

Abstract: An engine has an improved fuel injection control apparatus the pressure boosting and method that prevents misfire and prevents unburned fuel from entering the exhaust system. The fuel injection system has two pumps, a primary pump and a booster pump. When an abnormality occurs in the booster pump, it is stopped, and fuel injection is performed by the primary pump. When the booster pump is stopped, a fuel injection valve or an air intake device is regulated such that the air/fuel mixture formed in the combustion chambers will not misfire, and unburned fuel will not remain and enter the exhaust system.

Abstract: A fuel injection pump for internal combustion engines having a supply quantity adjusting device, in which a full-load stop for the quantity adjustment can be varied by the imposition of a stepping motor, and in which idling rpm governing is possible. The adjusting device has a tensed drag lever group, which acts as the stop lever for the stepping motor. If the stepping motor should fail in the idling position, emergency operation is possible by overpressing the drag lever.

Abstract: A fuel leakage prevention system for preventing undesired leakage of fuel into the combustion chambers of an internal combustion engine equipped with a pressure/time, cam actuated unit fuel injection system. The system includes a main housing containing an evacuatable chamber adapted to be connected by a first fluid conduit to a source of sub-atmospheric pressure by a check valve and manual shut off valve. The evacuatable chamber is also adapted to be fluidically connected to a common rail supplying fuel to the injectors by a solenoid controlled valve which is open during engine shutdown and closed during engine operation whereby fuel is withdrawn from the injectors by the vacuum upon engine shutdown.
