摘要:
A fuel injector-spark plug combination includes a fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine, and a spark plug for igniting the fuel injected into the combustion chamber, and has a spark-plug insulator including a first electrode, and includes a second electrode. The fuel injector and the spark-plug insulator of the spark plug are each disposed in a recess of a cylinder head of the internal combustion engine. The fuel injector and the spark-plug insulator of the spark plug are fixedly held in place in a shared connecting member arranged outside of the cylinder head.

The invention is directed to an arrangement for detecting the position of an accelerator pedal and/or a power-determining element of an internal combustion engine of a motor vehicle. The arrangement has at least two measuring devices as well as monitoring means which check the function of these measuring devices on the basis of the measuring signals thereof. In addition, a further measuring device in the form of a switch element is provided which likewise generates a signal representative of the position of an accelerator pedal and/or power-determining element of an internal combustion engine of a motor vehicle. A microcomputer selects on the basis of all three measuring signals at least one of the measuring signals for controlling the drive power of the engine in a motor vehicle. The switching element is a Hall switch.

An engine control device proposed for transmitting a control motion of an accelerator to an actuator of an engine, which includes mechanical transmission means and electrical transmission means with two clearances related to the accelerator. The two clearances are at the beginning and end of the mechanical transmission means so that the accelerator during normal driving can be actuated with particularly small forces, and at the same time reliable restoration of the accelerator is assured. The engine control device is particularly suitable for motor vehicles having traction control as well as travel speed control.

A fuel injection valve (1) having an integrated sparkplug for direct injection of fuel into the combustion chamber of an internal combustion engine and for igniting the fuel injected into the combustion chamber has a valve body (7) which, together with a valve closing body (10) operated by a valve needle (9), forms a seal seat. The valve body (7) and to some extent the valve needle (9) are surrounded radially by an insulating body (6). The insulating body (6) is in turn surrounded radially at least in part by a housing body (2). Ignition electrodes (15, 16) are provided on the valve body (7) and the housing body (2). The valve needle (9) has a first metal guide section (9a) guided in a swirl insert (14), a second metal guide section (9b) guided in the insulating body (6) and an insulating section (9c) arranged between the guide sections (9a, 9b). The guide sections (9a, 9b) are connected in a positive manner to the insulating section (9c).
摘要:
The invention is directed to an arrangement for detecting a changing operating parameter of an internal combustion engine and/or of a motor vehicle especially for measuring angle. The arrangement has at least two measuring devices detecting the particular operating parameter and these measuring devices have pregiven characteristics for generating signal values representing the operating parameter. The characteristics have respectively different forms and are linear over the value range of the operating parameter and the characteristic of at least one of the measuring devices has a slope which deviates from that of the other measuring device. Irregularities in the area of the common voltage supply of the measuring devices can be detected by correlating the signal values generated by the measuring devices having characteristics deviating from each other.
