A fuel metering system for an internal combustion engine having a fuel injection timing unit to indicate a timepoint during one or more engine strokes, a fuel metering element have a predetermined full stroke volume for metering fuel into an air-fuel mixing location during one or more of the engine strokes, and a fuel metering element controller to control the delivery of fuel by causing the fuel metering element to deliver one of a full stroke volume and a fraction of a full stroke volume to achieve a desired AFR. In some embodiments, power generator circuitry is provided to harvest power from the ICE to power at least one of the fuel injection timing unit, the fuel metering element, and the fuel metering controller.

Methods are provided for engines. In one example, method, at higher engine load, cool compressed air is drawn into an engine via an air intake passage, and at lower engine load, ambient air is drawn into the engine via a duct while retaining cooled compressed air in the air intake passage. The compressed air may be released from the air intake passage based on heat transferred to the compressed air during the lower engine load, in at least one example.

An object of the present invention is to provide an electronically controlled throttle device having a structure in which a resin cover is separated into a cover body portion and a connector portion, and has improved watertightness without increasing the size of the device. The electronically controlled throttle device of the present invention includes a motor 2, a throttle valve 4, a chassis 1, a resin cover 12, and a circuit board 104. The resin cover 12 has a first cover portion 12-1, a second cover portion 12-2, and a conductive wire 22 provided at a connection portion between the first cover portion 12-1 and the second cover portion 12-2. The connection portion is joined by forming a molten portion 23 around the conductive wire 22.

The inhibition device includes a micro-controller configured with a triggering condition including a number of intervals and, for each interval, a corresponding duration and a corresponding threshold. Each interval is a range specifying how much the vehicle's acceleration pedal has changed its position in terms of percentages of a pedal stroke. Each duration specifies the fastest time duration allowable for the acceleration pedal to attain a corresponding interval of pedal position change. The micro-controller converts progress signals of the acceleration pedal to corresponding percentages, obtains a difference DEF between the successive percentages, records a time duration RES between successive progress signals, and calculates DEF/RES=X. When X is greater than or equal to a threshold of a corresponding interval, the micro-controller sends an idle signal to the vehicle's engine control unit or intercepts the progress signals to prevent them from reaching the engine control unit.

A throttle operating device includes: a fixing member which is fixed to a vicinity of a grip formed at a tip of a handlebar of a vehicle; a throttle lever which is attached by extending from the fixing member and configured to be pivoted while the grip is gripped; and a detection sensor configured to detect a rotational operation angle of the throttle lever. A drive source of a vehicle is controlled based on the rotational operation angle of the throttle lever detected by the detection sensor, and a cover member is provided to cover an opening of the fixing member, and the cover member is formed with an accommodation portion capable of accommodating the detection sensor at a predetermined position.

A throttle operating device includes a fixing member, a throttle lever, and a detection sensor. A drive source of the transport is configured to be controlled based on the rotational operation angle of the throttle lever detected by the detection sensor. The throttle lever is configured to be rotated in a forward direction and a reverse direction. When the throttle lever is rotated in the forward direction, the drive source of the transport can be controlled. When the throttle lever is rotated in the reverse direction, a predetermined device mounted on the transport can be operated or an operation of the predetermined device can be stopped.

A throttle operating device includes a fixing member, a throttle lever, the throttle lever, a magnet which is configured to rotate in response to a rotational operation of the throttle lever, and a detection sensor. A drive source of the vehicle is configured to be controlled based on the rotational operation angle of the throttle lever detected by the detection sensor. A magnetic shielding unit is disposed in the fixing member and configured to cover a periphery of the magnet and the detection sensor to shield magnetism from the outside.

One or more techniques and/or systems are disclosed for automatically obtaining a profile for a set of accelerator pedal position sensors in a target vehicle. The profile can comprise a correlation of the position of the pedal to an output signal for one or more sensor in the set of sensors. A pedal position sensor signal reader can be used to automatically detect signals from one or more pedal position sensor in the target vehicle's accelerator pedal, while the pedal is released, depressed, and moving between the released and depressed positions. A pedal profile can be automatically generated using the output signals and corresponding pedal positions. Obtained data can be used to program a speed control device for the target vehicle. Correlated output can be used to adjust the speed of the vehicle by sending an emulated signal to the ECM, which may adjust the speed control system.

A general engine throttle apparatus includes a throttle body 12, a throttle valve 13, a throttle shaft 14, a driven gear 24, an electrically driven motor 15, and a detected body block 26. The throttle valve 13 opens and closes an intake air introduction hole 11. The throttle shaft 14 holds the throttle valve 13 and is rotatably supported by a holding hole 16 of the throttle body 12. The electrically driven motor 15 transmits a rotation operation force to the driven gear 24. The detected body block 26 is attached to another end part in an axial direction of the throttle shaft 14, and a state of the throttle shaft 14 is detected by a sensor. The driven gear 24 is integrally formed on one end side in the axial direction of the throttle shaft 14. The detected body block 26 is formed to have a maximum outer diameter that is smaller than a minimum inner diameter of the holding hole 16.
