engine controller

Abstract

The invention relates to an engine controller, an engine controller (16) for an internal combustion engine, in particular an internal combustion engine operated on diesel or heavy oil or on gas, wherein the internal combustion engine has a fuel supply with a magnetic actuator, in particular a common rail fuel supply device, wherein the engine controller (16) includes means (17, 18, 19) to automatically determine at least one magnetic The actual value of the characteristic parameter is evaluated in such a way that if the corresponding actual value deviates from the corresponding nominal value by less than a predetermined amount, then the engine controller (16) automatically deduces that the magnetic actuator is working normally, otherwise if the corresponding actual If the value deviates from the corresponding nominal value by more than a predetermined amount, the engine controller (16) automatically infers a malfunctioning magnetic actuator.

Description

Technical field [0001] The invention relates to an engine controller according to the preamble of claim 1. Background technique [0002] figure 1 The basic structure of a common rail fuel supply device known from the prior art of an internal combustion engine is shown. This construction is known from DE 101 57 135 B4. in this way, figure 1 The common rail fuel supply equipment includes at least one injector 1 for each cylinder of the internal combustion engine. Via the injector 1, fuel can be injected into each of the cylinders of the internal combustion engine. In addition, the common rail fuel supply equipment includes a pump device 3 having at least one low-pressure pump 5, at least one high-pressure pump 2 and a high-pressure pump storage 8 in order to deliver fuel from the low-pressure area 4 of the common-rail fuel supply equipment to its high-pressure area 6 , Wherein a pressure storage system 7 permanently under high pressure is provided in the high pressure region 6...

Problems solved by technology

However, this is only possible if maintenance work is to be carried out on the internal combustion engine anyway

There is therefore the risk that the magnetic actuator fails during operation outside regular maintenance intervals of the internal combustion engine and thus leads to an undesired shutdown of the internal combustion engine and thus to its cost-intensive downtime.
