Abstract: A system and method for operating an engine comprises an engine speed sensor generating an engine speed signal, a throttle position sensor generating a throttle position signal, a sensor module comprising at least one of a fuel pressure sensor generating a fuel pressure signal corresponding to a fuel pressure and a fuel temperature sensor generating a fuel temperature signal corresponding to a fuel temperature into the engine. A controller is coupled to the fuel injector, the engine speed sensor and the sensor module. The controller determines a pulse width duration for the fuel injector based on engine speed and throttle position, determining a pulse width correction factor as a function of at least one of the fuel temperature signal and the fuel pressure signal, determining a second pulse width duration based on the first pulse width, and operating the fuel injector with the second pulse width duration.

Abstract: A system for starting an engine of a vehicle has a fuel injector injecting fuel into a closed intake port to form an air fuel mixture. The system also includes an actuator rotating a crankshaft in a first direction to open the intake port by moving a piston within a cylinder coupled to the crankshaft. A combustion chamber defines between the cylinder and the port receiving the air fuel mixture through the intake port. The actuator rotates the crankshaft in a second direction to close the intake port. A spark plug ignites the air fuel mixture to start the engine. The engine also includes many other disclosed features.

Abstract: A method and system for operating an engine includes operating the engine with a first plurality of parameters associated with a first fuel type, comparing a detonation signal a first to a first voltage threshold, forming a plurality of vectors by storing detonation signal values that exceed the first voltage threshold, in vectors as vector values wherein later in time vectors include previous vector values, summing vector values for each vector to form a plurality of sum values and when one of the plurality of sums values exceeds a sum threshold, changing an engine controller to operate with a second plurality of parameters associated with a second fuel type.
