On-Cylinder Combustion Sensor

摘要

The invention relates to an internal combustion engine having at least one engine component (2) mounted on an engine block and at least one combustion chamber, whereby a knock sensor (3), which generates a signal as a result of the combustion process in at least one of the combustion chambers, is mounted to the engine block. It is an object of the invention to provide an internal combustion engine comprising of a knock sensor to affect an improved signal-to-noise ratio and reduced cross-coupling between the cylinders. Inventional the knock sensor (3) is mounted directly over the combustion chamber such that a signal resulting from the combustion process transmitted through the engine block and via the knock sensor (3) is generated, so that the combustion in the at least one combustion chamber is measured indirectly.
