摘要:
Disclosed herein are methods of cranking and/or operating an engine that eliminates the need for use of a cam sensor. The methods implemented with internal combustion engine comprising a plurality of cylinders whose firing sequence occurs over two revolutions of a crankshaft with a first set of cylinders comprising a power stroke during the first crankshaft revolution and a second set of cylinders comprising the power stroke of a second crankshaft revolution. The methods involve manipulating fuel injection command signals to occur out of their proper sequence, monitoring and engine indicator responsive to firing and non-firing of cylinders, and identifying correct engine phase based on fluctuations in the engine indicator. Also disclosed herein are software product embodiments comprising program code modules that cause a engine control unit to manipulate the generation of fuel injection command signals to take place outside their correct sequence.
