Abstract
A number of embodiments of combustion controls for two-cycle internal combustion engines wherein a sensor chamber is provided in which a combustion condition sensor is located. The sensor chamber communicates with the combustion chamber in such a way that only combustion products can flow from the combustion chamber into the sensor chamber. Various valving and control arrangements for achieving this purpose are disclosed.
