Cylinder identifying apparatus for a multi-cylinder internal combustion engine |
摘要 |
A cylinder identifying apparatus for a multi-cylinder internal combustion engine can generate an exact reference position signal at an earliest possible time during engine start-up operation, thereby making it possible to identify predetermined reference positions of each cylinder in a highly accurate manner. A first signal generator 1 is provided on a camshaft for generating a cylinder identifying signal SC in synchronization with the rotation of the camshaft. A second signal generator 4 is provided on a crankshaft for generating, in synchronization with the rotation of the crankshaft, a pulse signal P containing a series of pulses each corresponding to predetermined first and second crank positions of each cylinder. A reference position signal generating circuit 2 generates, based on the output signals from the first and second signal generators, a reference position signal ST containing a series of pulses each exactly indicating the predetermined crank position of each cylinder and a cylinder identifying information signal indicative of the cylinder corresponding to each pulse of the reference position signal.
