NEW METHOD OF CYLINDER GAS SAMPLING CYCLE BY CYCLE USING MICROPROCESSOR

Describes a new gas sampling method which makes it possible to sample cylinder gas in individual cycles fast and successively, and obtain the other combustion variables from the engine at the same time. Two microprocessors were introduced in the system, one for control and the other for data processing. They were operated in parallel on-line real time depending on the engine speed. It was proved that the gas sampling in the cylinder could be achieved in 16 successive engine cycles. At the same time, the indicated mean effective pressure was calculated easily by either adding or exchanging the programs of the microprocessor. In addition, the value of each air-fuel ratio in 16 successive engine cycles was calculated from the gas concentrations of the sampled burnt gas in the cylinder.
