Definitions
- the invention relates to a fuel injection system according to the preamble of the main claim.
- Heating device for heating the fuel at its outlet end as described as such in DE 196 29 589 Al.
- the power loss of the current-carrying solenoid is used to heat the fuel, on the other hand is provided as a heat exchange section acting as a heat pump Peltier element comprising the valve needle and the fuel therein.
- An advantage of the invention is that the heating concept of the fuel injection system according to the invention is independent of the control unit platform and the type of fuel injector used, since the heatable adapter can be introduced into both a direct injection fuel injector and a fuel injection valve for port injection.
- Another advantage of the invention is the increase in starting safety, especially at
- Another advantage of the fuel injection valve according to the invention is that in the cold state, the idle quality of the engine is improved by heating the fuel by means of the fuel injection system according to the invention. Furthermore, it is advantageous that the fuel can be heated independently of the start of the engine or by the operation of the ignition.
- the fuel injection system described in the invention is simple, robust and flexible, so that also a cost-optimizing effect in production is achieved.
- Fig. 1 shows an inventive fuel injection system 1 with at least one
- a thermal switch 2 is provided, which is connected to an external contact-making device 3 and with the heatable adapter Ib.
- the thermal switch 2 has a thermal sensor, which triggers a switching operation of the thermal switch 2 at a temperature of the fuel rail Ic located in the fuel 8, which is below a predetermined threshold temperature.
- the thermal switch 2 itself can be designed either as a bimetallic strip or as a thermistor.
- electrical heating elements 5 are provided which heat the fuel 8, which flows from the fuel rail Ic into the corresponding fuel injection valve Ia. A heating of the fuel 8 is advantageous if the finely atomized fuel 8 would condense due to a cooled combustion chamber on the cold combustion chamber wall.
- the thermal switch 2 has at least two electrical terminals 7, 7a, wherein an electrical terminal 7a is connected to the external contact producing device 3.
- a closed switch position 9 of the device 3 is at least a prerequisite for the operation of the thermal switch 2 and thus for the heating of the fuel eighth
- the external device 3 may, for. B. be a door contact switch, a remote control, a seat sensor o. ⁇ ., By which it is possible, even before starting the internal combustion engine (eg., 10 to 30 s) to set the heating of the fuel 8 in motion.
- the internal combustion engine eg. 10 to 30 s
- the electrical heating elements 5 are arranged in the heatable adapters Ib and are connected, on the one hand, to a contact 7 of the thermal switch 2 and, on the other hand, to a circuit ground 10.
- the invention is not limited to the illustrated embodiments and is applicable, for example, to direct injection fuel injectors and to fuel injectors that inject into a draft tube.
