Summary:

The emission of light during combustion is investigated onstandard production engines. For this purpose, a light pipe isintegrated into the center electrode of the spark plug. Theemerging radiation is measured and converted using simple siliconphotocells.The emission of light during combustion has a similar time curveto that of pressure. The start of light emission correlates withthe start of mass burn. The position of maximum radiation coincideswith the position of maximum combustion pressure.From the curve of light emission received, one can drawconclusions concerning combustion. From the position of the lightemission over the crank angle, one can read whether the mixture hasbeen ignited at the correct time or not. Cyclic fluctuations giveinformation on the smooth combustion of the engine. Any knockingwhich occurs can be detected with an appropriate filter.The measuring spark plugs which have been developed allow lightto pass through for a considerable period of time when used withunleaded fuel
