摘要： A fuel injection control apparatus of an engine, which can inhibit a learning time from lengthening, is provided. With the fuel injection control apparatus, learning control over one of a first fuel injection valve and a second fuel injection valve is exercised in an operating region of the engine where fuel is injected from each of the first fuel injection valve and the second fuel injection valve, and the change rate of a learning value by the learning control is altered in accordance with an injection ratio between the first fuel injection valve and the second fuel injection valve.

摘要： In a fuel system for delivering pressurized fuel both to an internal combustion engine and to an exhaust installation, the fuel system includes two separate branches for delivering fuel to the internal combustion engine and to the exhaust installation, and includes a primary fuel pump delivering fuel to both branches of the fuel supply circuit. The primary fuel pump output is controllable independently of the engine speed. The pump output may be controlled such that the pressure of fuel in the fuel supply circuit depends on whether fuel is to be delivered to the exhaust installation. The fuel system may include a hydraulically controlled shut-off valve arrangement which is forced to switch depending on the pressure in the fuel supply circuit.

摘要： An engine controller controls a direct fuel-injection engine including a fuel injection valve for directly injecting a fuel into a cylinder and a valve overlap period adjusting mechanism for adjusting a valve overlap period between an open period of an intake valve and an open period of an exhaust valve. The engine controller is provided with an acceleration request sensor for detecting an acceleration request of a driver, and when the acceleration request occurs and a top surface temperature of a piston in the cylinder is lower than a predetermined temperature, the engine controller extends the valve overlap period between the open period of the intake valve and the open period of the exhaust valve, ranging before and after an exhaust top dead center.

摘要： A method of protecting a direct injection fuel injector in a multi-fuel engine, the method includes selectively operating the multi-fuel engine with a directly injected fuel introduced through the direct injection fuel injector and a second fuel; when fuelling the multi-fuel engine with the second fuel, selectively commanding a fuel system protection technique when determining that the direct injection fuel injector requires cooling, an age of directly injected fuel is above a predetermined value, transmission status has changed, an engine shutdown event has occurred and a global positioning system signal indicates an engine shutdown event will occur; wherein the fuel system protection technique includes commanding that the directly injected fuel be a portion of total fuel consumed and reducing quantities of the second fuel that is injected so that total fuel consumed equals a desired amount of fuel measured on an energy basis.

摘要： A fuel injection control system for an internal combustion engine includes a plurality of first energy storage elements each for supplying a high voltage to a fuel injection solenoid valve, boosting circuits each for boosting a battery voltage and electrically charging one of the first energy storage elements, a second energy storage element for accumulating electrical energy of the battery voltage, and a switching circuit for transferring the electrical energy between the plurality of first energy storage elements via the second energy storage element. This configuration enables the fuel injection control system for an internal combustion engine to implement stabilized supply of a fuel by obtaining within a short time the high voltage needed to operate the fuel injector both accurately and reliably, and to contribute to cost reduction by, for example, alleviating capability requirements and part performance requirements of the individual boosting circuits.
