Improved re-starting of internal combustion engine by detection of relative position of a component linked to crankshaft position, uses counting of displacements to maintain record of engine position to guide control of fuel and ignition

摘要

The relative position of crankshaft (35) or pistons is determined (31a,31b) by incremental counting of its displacements, and the control of the engine re-starting is determined by either the last detected position of the engine component or a position defined by the engine control computer (15) independently of the detected positions.
