Abstract

The present invention relates to an engine control unit (16) of an internal combustion engine which is especially operated by diesel fuel, heavy fuel, or gas. The internal combustion engine has a fuel supply system, and specifically a common rail fuel supply system including solenoid actuators. The engine control unit (16) includes means (17, 18, 19) in order to automatically detect and evaluate an actual value of at least one magnetic variable of at least one solenoid actuator (15) in case the fuel supply system is depressurized during a stoppage of the internal combustion engine. When each actual value deviates from a corresponding target value by a predetermined amount or less, the engine control unit (16) automatically estimates a properly operating solenoid actuator. When each actual value deviates from a corresponding target value by a predetermined amount or more, the engine control unit (16) automatically estimates an improperly operating solenoid actuator.

Description

Engine controller
Technical field
The present invention relates to a kind of engine controller of preamble according to claim 1.
Background technique
Fig. 1 shows the essential structure of the common rail fuel supply equipment known by prior art of internal-combustion engine.This structure is known by file DE 101 57 135 B4.So, the common rail fuel supply equipment of Fig. 1 comprises at least one sparger 1 respectively for each cylinder of internal-combustion engine.Via sparger 1, fuel is during can to spray in the cylinder of internal-combustion engine each.In addition, common rail fuel supply equipment comprises the pump-unit 3 with at least one low pressure pump 5, at least one high-pressure service pump 2 and high-pressure service pump storage 8, fuel is transported to its high-pressure area 6 from the area of low pressure 4 of common rail fuel supply equipment, wherein, in high-pressure area 6, between pump-unit 3 and sparger 1, be provided with the pressure storage system 7 be in lastingly under high pressure.This lasting place pressure storage system 7 (it is also referred to as common rail) under high pressure has multiple storage unit 9.Storage unit 9 is with pump-unit 3 and be connected via the pressure duct 10 be in lastingly under high pressure to each other.In addition, pressure storage system 7, i.e. storage unit 9 are connected with sparger 1 via the pressure duct 11 be temporarily under high pressure according to injection beat.Be associated with switch valve 12 according to the pressure duct 11 (it connects sparger 1 and storage unit 9) that injection beat is temporarily under high pressure, it supplies fuel according to injection beat to sparger 1.An associated limit pressure valve 13 in the storage unit 9 of pressure storage system 7 and scavenging air valve 14.
In such common rail fuel supply equipment, use magnetic actuator more and more as final controlling element.Fig. 1 like this demonstrates, and the sparger 1 of fuel facility manipulates via magnetic actuator 15.In addition, such magnetic actuator can be installed in the region of low pressure pump 5, high-pressure service pump 2 and in the region of valve 12,13 and 14.Engine controlling unit 16 is in operation and manipulates magnetic actuator 15.
Do not exist so far and be arranged on the possibility checking magnetic actuator in internal-combustion engine place or the state in fuel facility.And in order to check that such magnetic actuator must come close to fuel facility like this, is connected to magnetic actuator place by special measuring device, to make it stand functional check.But this only so just may when anyway wanting putting maintenance into practice to work at internal-combustion engine place.Therefore there is this risk, the magnetic actuator be namely in operation outside the regular service intervals of internal-combustion engine malfunctioning and therefore cause the less desirable shutdown of internal-combustion engine and and then cause its cost concentrate downtime.
Summary of the invention
Set out thus, the object of the invention is to provide a kind of novel engine controller.This object is realized by one engine controller according to claim 1.According to the present invention, this engine controller comprises device, automatically to measure the actual value of at least one magnetic characteristic parameter of at least one magnetic actuator when internal-combustion engine stops and assessing like this in the stress-free situation of fuel facility, if namely corresponding actual value and corresponding rating value depart from and are less than predetermined amount, so engine controller infers the magnetic actuator of normal work automatically, if instead corresponding actual value and corresponding rating value depart from more than predetermined amount, so engine controller infers the magnetic actuator of malfunction automatically.
Utilize the present invention to propose first, device is integrated in the engine controller of internal-combustion engine, automatically to implement the functional check of the magnetic actuator of fuel facility in the stress-free situation of fuel facility when internal-combustion engine stops.To this, engine controller automatically measures the actual value of at least one magnetic characteristic parameter of at least one magnetic actuator and automatically assesses this actual value like this, if namely corresponding actual value and corresponding rating value depart from and be less than predetermined amount, so automatically infer the magnetic actuator of normal work.If instead corresponding actual value and corresponding rating value depart from more than predetermined amount, so engine controller automatically infers the magnetic actuator of malfunction.
Utilize the present invention may outside the periodic maintenance work at internal-combustion engine place and therefore when the external internal-combustion engine of regular service intervals stops in the stress-free situation of fuel facility automatically without manually closely and nothing makes the magnetic actuator of fuel facility automatically stand functional check at fuel facility place or in the place of working about this at internal-combustion engine place.The magnetic actuator worked with having fault may be inferred in time thus and arrange in time its other safeguard or change, to avoid thus due to the malfunctioning unexpected shutdown of magnetic actuator.
Preferably, this engine controller has: interface, so as to manipulate magnetic actuator and with its exchange data; Have equally for automatically measure magnetic actuator should or each magnetic characteristic parameter actual value hardware aspect assembly and for automatic evaluation magnetic actuator should or the assembly of software aspect of actual value of each magnetic characteristic parameter.
Such design proposal of engine controller is preferred and allows the full-automatic functional check of the magnetic actuator of fuel facility.
