The idea to monitor the combustion in an internal combustion engine and using the obtained data to control combustion in the engine has been around for sometime now. There are two well-known methods, although in the capacity of lab epxeriments which had been developed under this principle. One features the analysis of combustion pressure and the other features the analysis of ionic currents detected in the combustion gas. Although highly precise analysis can be achieved by the former, there are problems in the installation of sensors for detecting combustion pressure, also in the durability and cost of such sensors. As for the latter, there are also problems in installing sensors for detecting the ionic currents and the reliability of obtained data from such sensors is still questionable. For these reasons, no internal combustion engine control systems have been practicalized that use these methods, i.e. for continuously monitoring all cylinders in an internal combustion engine of a car.
