Definitions
- a control device such as Eccentric device
- the object of the invention is a method and a device for injecting fuel into a combustion chamber to create a diesel engine with the harmful Exhaust emissions in a simple manner at predetermined Load conditions of the engine are herabsetzbar.
- the injection timing in the direction of "early" achievable is, that is, when the start of delivery and the injection time is done before a TDC position, is a so-called soot formation at partial and light load avoided.
- This is done with an adjustment of the pump piston in the injection pump at partial load and low load achieved high injection pressure at the injector, the in a range of about minus 20 ° to minus 10 ° of the piston angle before TDC of the engine piston and in a range of Speed of the pump piston from about 2.5 to 3.5 m / s lies.
- the high injection pressure at a crank angle of about minus 14 ° before TDC of the engine piston and at a Speed of about 3 m / s of the pump piston is.
- the early start of delivery and injection time will be achieved by the pump piston of the injection pump with its control edge via a control rod in a conveying position in the direction of "late” is rotatable and this Twisting movement "late” an axial positioning movement to corresponding injection start in the direction of "early” on with the Pump piston operatively connected control device, such as a Eccentric, is superimposed.
- the Pump piston operatively connected control device such as a Eccentric
- the axial adjustment of the pump piston takes place in dependence from the piston position of the engine and this points the eccentric held on an eccentric Rocking lever on, with its free end by means of a roller between the pump piston and a camshaft is arranged and over the eccentric to the camshaft in an injection position in the direction of "early” adjustable is.
- This eccentric adjustment makes it easier Way by adjusting the eccentric a start of delivery in Direction "early” or “late”, that is, the Roller can be adjusted according to the cam of the camshaft be so that according to the invention at part load or Low load, the adjustment in the direction of "early” is selectable and then, for example, at full load below again an adjustment towards “late” or otherwise can be made.
- an internal combustion engine 1 for example a diesel engine, takes place by means of a fuel-conveying pump unit 2, via a pressure line 3 with an injection nozzle 4 is connected.
- the injection pump 2 has an adjustable pump piston 5 with a control edge. 6 and a long groove 7.
- the end of funding is determined by the position the control edge 6 after a rotation of the piston. 5 determined, which formed according to the objective is. Determining for the promotion are also the Zulaufbohronne 8, which are significantly contributing to the Delivery stroke and the delivery rate.
- the axial increase of the pump piston 5 via a arranged on a rocker arm 9 roller 10, in operative connection with a cam 11 of a camshaft 16 is.
- the adjustable according to the setting "early” or “late” is.
- the position of the roller 10 changes to the cam 11 and the injection timing is variable, that is, the injection timing may be in accordance with Load condition of the engine to be changed, resulting in interaction with the promotion of the fuel over the position the control edge in the injection pump 2 takes place.
- Fig. 2 in more detail with reference to the diagram, is the "early" injection time E1 before the "late” injection time E in a range of minus 20 ° to minus 10 ° of the crank angle K provided before the TDC and the injection occurs at a speed V of the pump piston 5 in a range of 2.5 to 3.5 M / s.
- the injection timing is advanced by 14 ° crank angle K. and this at an increased piston speed V of 3 m / s of the injection pump 2.
- the advance of the injection timing takes place at the shown embodiment by about 14 ° crank angle from E to E2, wherein the start of delivery of the fuel in particular by achieved the adjustment of the eccentric 12 on the pivot lever 9 and the shift of fuel production from approx. 1.8 m / s to 3.5 m / s by appropriate rotation of the Pump piston 5 to E1. Both measures allow a transfer of the start of delivery and the injection point in the direction of "early”.
