Definitions
- Modern internal combustion engines are regulated and controlled using an ECU (Electronic Control Unit). If the injection valves for engines are operated electrically by the ECU, then it is necessary to determine the phase position at the start of the internal combustion engine. With a 4-stroke petrol engine, phase detection indicates whether the piston is in the
- Figure 1 Overview of the overall system 1: cylinder
- the present method is illustrated in FIG. 1 using an exemplary embodiment. It uses the agent 3 of the
- Means 2 is observed. Means 2 usually serve to start the combustion process 1.
- Detection of an ignition spark can be used to determine the phase.
- Combustion chamber compressed after every 720 ° KW. This
- This adjustment may span 10 iterations. It is possible that some cylinders are currently in a compressed state. In this case the necessary energy level is incorrectly determined. At least half of the cylinders are in a sufficiently uncompressed state
- phase detection and ignition control is carried out continuously on all cylinders with the help of the ion current measuring circuit. After the ignition has been issued, the determined characteristic value is replaced by the
- ECU is recorded if necessary and it is classified into ignition or no ignition. If an ignition misfire is detected, several firings can be evaluated in the period of sweeping over a piston of the compression TDC if the ignition repetition frequency is sufficient, so that a stable statement regarding the cylinder removed by 360 ° KW results. This means that the ignition does not occur in the case of a cylinder and the cylinder which is removed at 360 ° KW the spark remains. From now on the phase is known.
- the right cylinder After one revolution at the latest, after the reference mark on the crankshaft sensor wheel has passed, the right cylinder can be injected.
- the switch-off current (the energy introduced into the coil) is kept constant. If necessary, the battery voltage must be detected by the ECU and the closing time / closing angle corrected. Feature formation (as an example on the inductive ignition system)
- the ion current measuring device can definitely detect part of the spark current, and as a rule is fully controlled thereby. If an attempt is made to ignite according to the adjusted energy level, the ion current is integrated during the duration of an ignition spark, the result is recorded by a sample and hold and made available to the ECU.
- the measured signal is low-pass filtered and observed with a peak value detection.
- the peak value is supplied to the ECU, this peak value is then compared with a threshold.
- FIG. 3 shows an example of the signals occurring on the inductive ignition system. A distinction is made between “no ignition” and “ignition”. The following are shown: the secondary current which flows in L 2 (see FIG. 2); the ion current which is measured with the ion current measuring device and, for example, the low-pass signal of the measured ion current, which is intended to show the formation of features. How an inductive ignition system works is assumed to be sufficiently known. First, the ignition energy is introduced into the ignition coil via the primary side by closing the transistor. At time T 0 , the ignition transistor T is switched to high resistance and the energy in the coil now drives a current in the primary and
- the current in the secondary winding is called i sec and can be seen in the first diagram.
- the entire arrangement behaves like an LC resonant circuit with one coil each on the primary and secondary side.
- the capacities are determined by spreading and
- the low-pass filtered ion current signal TP ⁇ i ion ⁇ reaches a significantly higher level than the signal when the ignition has not occurred.
- the two cases are easy to distinguish from the ECU.
- FIG. 4 The flow diagram described in FIG. 4 applies to all or correspondingly selected cylinders that are to be observed for phase detection. With a high-cylinder engine, you will probably not need all cylinders for phase detection. This exemplary flow chart is intended to provide a quick overview of the process. Core and advantages of the invention
- the core of the invention is the use of the ion current measurement for ignition spark observation and the phase detection derived therefrom. If an ion current measurement is available on a vehicle, phase detection can be installed with little additional technical effort.
