    摘要: A method of transmitting information making it possible to monitor the operation of an internal combustion engine, includes the steps of: measuring the angular position of a crankshaft via an absolute position sensor provided with a digital output, and transmitting at a frequency f1 to an engine control unit the measured angular position information, encoded in a data string containing N1 bits, transmitting at a frequency f2 of the measured angular position information, encoded in a data string containing N2 bits, the number N2 of bits being greater than the number N1, the frequency f2 being less than or equal to the frequency f1. The encoding in N1 bits allows transmission of angular position information at low resolution, whereas the encoding in N2 bits allows the transmission of high resolution information, able to detect misfirings.

    摘要: The invention relates to a method and device for determining a phase position between a crankshaft and a camshaft of an internal combustion engine. An internal combustion engine is provided with a crankshaft, a camshaft, at least one cylinder and an intake tract to which gas inlet valves are assigned that control the gas supply from the intake tract to the one or more cylinders and that are driven via the camshaft. The intake tract is associated with a pressure sensor that detects an intake tube pressure in a manifold of the intake tract. The phase position is determined depending on the intake tube pressure detected. The inventive method and device allows to determine the phase position in a simple manner and without any additional sensor system.
