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.
Claims10
A method of starting an engine of a vehicle comprising:
- sensing a proximity of a battery key to the vehicle using an electric field sensed by a proximity module;
- determining a battery temperature of the battery key when the battery key is proximate the vehicle in response to sensing;
- when the battery temperature is below a predetermined temperature, powering a battery heater;
- coupling the battery key to a controller of the vehicle, said battery key comprising a key identifier, said battery key comprising a battery cell disposed therein;
- communicating a key identifier from the battery key to a controller of the vehicle, said controller having a stored identifier;
- comparing the stored identifier and the key identifier;
- and
- in response to comparing, providing power from the battery cell of the battery key to an actuator to rotate a crankshaft of the engine.
A system for starting an engine of a vehicle comprising:
- a proximity module sensing a proximity of a battery key to the vehicle using an electric field sensed by a proximity module of the vehicle;
- a temperature sensor sensing a battery temperature of the battery key and generating a battery temperature signal when the battery key is proximate the vehicle in response to sensing;
- a heater controlled in response to the battery temperature signal;
- a controller disposed within the vehicle;
- the battery key coupled to the controller of the vehicle, said battery key communicating a key identifier to the controller of the vehicle, said battery key comprising a battery cell disposed therein;
- said controller having a stored identifier therein, said controller comparing the stored identifier and the key identifier;
- and
- said controller, in response to comparing, providing power from the battery cell of the battery key to an actuator to rotate a crankshaft of the engine.
