Abstract
An apparatus for detecting the in-cylinder pressure of an internal combustion engine having a plurality of cylinders and for providing in-cylinder pressure parameters is described which comprises a plurality of pressure sensors for detecting the pressures in the respective cylinders, a signal selector, a microcomputer and a crank angle sensor. The signal selector sequentially selects the pressure signals from the pressure sensors to be transfer to the computer and the computer computes the pressure parameters in accordance with the received signals for each of the cylinders. The operation of the apparatus is executed by referring to the crank angle signal from the crank angle sensor.
