Abstract:
An engine comprising an engine body having at least one variable volume combustion chamber, at least one intake port opening into the chamber, an induction system communicating with the intake port, an intake valve being moveable to regulate communication between the induction system and the combustion chamber through the port, a camshaft driving the intake valve, at least one fuel injector, a fuel injector control module configured to drive the at least one fuel injector, a variable valve timing mechanism configured to vary a position of the camshaft to vary a timing of actuation of the intake valve, a sensor configured to sense a position of a camshaft and to generate a signal indicative of the camshaft position, a variable valve timing mechanism control module communicating with the sensor and being configured to determine a first camshaft timing and to control the variable valve timing mechanism to at least approximate the first camshaft timing, the fuel injection control module being configured to read a first fuel injection amount from a fuel injection map and to adjust the first fuel injection amount based on a deviation of the signal and the first camshaft timing, the fuel injector configured to supply the first adjusted fuel injection amount for combustion in the combustion chamber.
