Abstract:
A system for controlling an internal combustion engine has an in-cylinder pressure sensor, a crank angle sensor and a controller coupled to receive inputs from the pressure sensor and crank angle sensor. The controller is configured to convert the cylinder pressure input into a combustion metric indicative of the combustion occurring in the measured cylinder and control fuel input and timing into the engine based on the combustion metric. The controller samples the in-cylinder pressure sensor at a high frequency during critical combustion events and at a lower frequency during the non-critical cylinder conditions.

Claim (Index 1):
An apparatus for controlling operation of an internal combustion engine, comprising:\n an in-cylinder pressure sensor configured to measure pressure in a cylinder of the engine and generate a corresponding pressure signal; a crank angle sensor configured to measure the crank angle of the engine and generate a corresponding crank angle signal; and an engine control unit couplable to the pressure sensor and the crank angle sensor, the engine control unit configured to: (a) sample the pressure signal and the crank angle signal at a specified frequency, the specified frequency in a first range of the crank angle that includes a piston top-dead-center being greater than the specified frequency in a second range of the crank angle, (b) calculate a combustion metric indicative of the combustion occurring in the cylinder as a function of the pressure signal and the crank angle signal, and (c) determine fuel input signal, throttle position signal, and an ignition timing signal for the engine based on the combustion metric.
