Abstract
Some embodiments relate to an internal combustion engine that includes a combustion chamber and a rotating component. The internal combustion engine further includes a sensing system that detects an angular position of the rotating component. A controller calculates a ratio between air and fuel in the combustion chamber based on the detected position of the rotating component. As an example, the rotating component may be a crankshaft where the controller calculates a speed of the crankshaft and an acceleration of the crankshaft based on the detected position of the crankshaft.
Claims17
An internal combustion engine comprising:
- a combustion chamber;
- a rotating component;
- a sensing system that detects an angular position of the rotating component;
- and
- a controller that calculates a ratio between air and fuel in the combustion chamber based on the detected position of the rotating component.
A method comprising:
- receiving data indicating a volume of a combustion chamber;
- and
- calculating, with a processor, a ratio between air and fuel in the combustion chamber based on the volume of the combustion chamber.
