Definitions

  • US 4944271 discloses a manner of correcting the pressure measurement by an offset of the pressure sensing means, which is determined by comparing the pressure in the cylinder, as detected by the pressure sensing means at the time when the crank is at the top dead center position as detected by the crank angle sensor, with the product of the compression ratio of the engine and the manifold pressure as detected by the manifold pressure sensor. An additional procedure for compensating the effects of temperature is also disclosed.
