摘要:
A fuel injection system for internal combustion engines in which a high pressure fuel reservoir is provided, from which fuel is supplied to injection valves in an electrically controlled manner. In order to reduce damage which occurs when there are leaks from the high pressure reservoir, the high pressure reservoir is enclosed by a sheath that can capture the emerging leakage fuel.
摘要:
A method and a device for monitoring a fuel-metering system, in particular a common-rail system for a diesel fuel engine. A defect is recognized on the basis of an output signal from a structure-borne noise sensor.
摘要:
In a method and device for controlling an internal combustion engine, particularly a diesel engine, when the internal combustion engine is started up, a power-regulating, controlling mechanism is triggered in a first step so as to allow it to assume a starting position. A starter is triggered in a subsequent step. An interrupting device, which is operatively connected to the power-regulating, controlling mechanism, is released only after a safety condition is fulfilled.
摘要:
A fuel injection valve which is provided for high pressure injection in self-igniting internal combustion engines and has a solenoid valve for controlling the injection. To trigger this solenoid valve, a control circuit is provided which is subdivided into a first circuit part and a second circuit part. The second circuit part is separate from the first circuit part, which jointly serves to control a number of injection valves, and are disposed on each individual injection valve. The housing is clipped onto the fuel injection valve and fuel flows through its interior for cooling purposes.
摘要:
A fuel injection device for internal combustion engines with a high-pressure fuel pump which pumps fuel out of a low-pressure space into a high-pressure collecting space which is connected by high-pressure lines to injection valves projecting into the combustion space of the internal combustion engines to be supplied, wherein the high-pressure collecting space is formed by a distributor rail resistant to high pressures which is integrated into the wall of a cylinder-head cover arranged on the internal combustion engine.
摘要:
A method for sensing the temperature of the air supplied to the combustion chambers of an internal combustion engine for the purpose of detecting air mass. Air temperature can be measured using an inexpensive detector having a transfer function exhibiting a delayed response. Dynamic performance is improved by applying to the detected temperature a temperature correction value that is obtained by applying a transfer function that is substantially the inverse of the transfer function of the temperature detector.
摘要:
A method and apparatus reduces the amount of residual injection fluid within an injection pump. When an associated internal combustion engine is shut off, a stop valve in the injection pump is closed and an injection timing mechanism is shifted into an early position after a predetermined waiting time has expired. The length of the waiting time is selected in order to enable the injection fluid already supplied to the pump at the instant that the stop valve is closed, to enter the interior of the pump while the injection timing mechanism is in an existing working position.
