A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.

Electronic fuel injection system and method for engines

Engine systems which are easier starting and more resistant to degradation and discharge of their batteries are desirable in a wide range of equipment markets. The present engine systems utilize a selection module which selective switches from a first state when the battery is adequately charged to a second state which enables the use of auxiliary components such as special starting stators and regulators which can power the engine control module even when the battery is too discharged to power the engine control module directly.

Engine system, and method of starting the engine

An integrated ignition and electronic auto-choke module for an internal combustion engine and an internal combustion engine including the same. In one aspect, the module includes a housing that is configured to be mounted to an engine block of an internal combustion engine. The housing may contain at least a portion of a first temperature sensor that measures a first temperature indicative of an engine temperature. The housing may also contain a controller and at least a portion of an ignition circuit. The controller may be coupled to the first temperature sensor and configured to determine a starting position of a choke valve based on the first temperature and operate an actuator to move the choke valve into the starting position accordingly.

A system for tracking oil health of an engine includes an electronic fuel injection system which includes an electronic governor control unit. The electronic governor control unit is programmed to track engine parameters, calculate oil health based on the tracked engine parameters and on engine type, and display an indication of oil health.

A multiple-keyed crankshaft and flywheel provides for different ignition timing options for an internal combustion engine. The crankshaft of the engine includes multiple keyways set at designated angular displacements of the crankshaft that correspond with keyways on a flywheel for providing different timing options for the engine. The flywheel may be mounted to the crankshaft by aligning one of the keyways of the flywheel to one of the keyways of the crankshaft related to a particular ignition timing selection.

Multiple-keyed flywheel and engine crankshaft

An electronic device for the ignition system of an engine, which may incorporate circuitry for voltage amplification via transformer action, while also containing circuitry for sensing operational parameters, circuitry for calculation of derived values from the sensed data or operational parameters, circuitry for storage of the data and derived values, circuitry for engine system control, and circuitry for the wireless communication of data and derived values.

Ignition module for internal combustion engine with integrated communication device

Systems and methods for electronically controlling the fuel-to-air ratio of a fuel mixture supplied to an internal combustion engines are disclosed. In one aspect, electronic control systems and methods are provided that determine and automatically move a choke valve in accordance with a first ramp having a first characteristic that is dependent on engine temperature and ambient air temperature. In another aspect, an integrated ignition and electronic auto-choke module is provided. In yet another aspect, electronic control systems and methods are provided that dynamically control a movement characteristic of a choke valve using a feedback loop.

Systems and methods for electronically controlling fuel-to-air ratio for an internal combustion engine

An electrical system for use with an alternator that supplies electrical power, an internal combustion engine including such an electrical system, and related methods of operation are disclosed. In one example embodiment, such an electrical system includes a first circuit portion configured to govern whether the power is communicated from the alternator system to a terminal associated with a battery and/or a load, and a second circuit portion configured to determine whether a voltage is elevated above a predetermined threshold and to provide a first signal upon determining that the voltage is so elevated. The electrical system also includes a third circuit portion coupled at least indirectly to the other two circuit portions. The third circuit portion is configured to provide a second signal upon receiving the first signal, the second signal being configured to cause the first circuit portion to cease allowing communication of the power to the terminal.

Overvoltage protection system and method

The alternator on an engine has a set of stator coils which are connected to supply current to power accessories and current for a battery charger when the engine is running. When the ignition is turned off, a braking switch is closed which short circuits the stator coils. The resulting high current in the stator coils produces a braking torque on the engine shaft that brings it and any attached implement to a rapid halt.
