Abstract
An internal combustion engine is analyzed by an apparatus having a data processing capability. The engine has a plurality of cylinders and a battery operative to power a starter motor. The apparatus measures a time dependence of voltage level or current draw at the battery while the engine is being cranked by the starter motor. The apparatus also measures a respective time dependence of pressure at each of one or more locations in the engine. From the measured time dependence of voltage level or current draw, the apparatus determines a respective value indicative of a compression for each of the plurality of cylinders. Furthermore, the apparatus determines the presence or absence of one or more defects in the engine from the one or more measured time dependences of pressure.
