Abstract
Present embodiments relate to an electronic fuel injection throttle body assembly for an internal combustion engine. More specifically, but without limitation, present embodiments relate to an improved electronic fuel injection (EFI) throttle body which has a remote communication capability as well as improved throttle position sensing.
Claims7
An electronic fuel injection throttle body, comprising:
- a throttle body having a first bore formed therethrough and including a throttle valve disposed in said first bore, and a second bore formed therethrough and including a second throttle valve disposed in said second bore;
- a first fuel injector extending into said throttle body and a second fuel injector extending into said throttle body;
- a channel disposed in each of said first bore and said second bore, said channel in fluid communication with a corresponding of said first fuel injector or said second fuel injector;
- and
- a plurality of openings in fluid communication with each said channel, whereby fuel is injected from said first or said second fuel injector into said first or said second bore through said plurality of openings;
- a remote short range communications module configured for, providing and receiving data remotely from said electronic fuel injection throttle body;
- an electronic control unit mounted to a side of said throttle body and communicatively coupled to said remote short range communications module;
- and
- a non-transitory, processor-readable storage medium in communication with the electronic control unit, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the electronic control unit to:
- transmit and receive a plurality of data through the remote short range communications module to an external computing device;
- receive inputs from the remote short range communications module in response to the plurality of data;
- and
- output control signals to the electronic fuel injection throttle body to change an operating condition of a combustion engine.

An electronic fuel injection throttle body, comprising:
- a throttle body having an upper inlet and an lower outlet;
- a first bore and a second bore extending through said throttle body between said upper inlet and said lower outlet;
- a throttle valve disposed in each said first bore and said second bore;
- at least one first fuel injector extending into said throttle body on a first side toward said first bore;
- at least one second fuel injector extending into said throttle body on a second side toward said second bore;
- a first throttle shaft extending through said first bore and a second throttle shaft extending through said second bore, at least one said throttle valve mounted on each said throttle shaft;
- a throttle lever assembly disposed on one side of said throttle body, said first throttle shaft and said second throttle shaft connected to said throttle lever assembly to rotate with movement of said throttle lever assembly;
- and
- an electronic control unit disposed on an opposite side of said throttle body from said throttle lever assembly, said electronic control unit having a recess which receives an end of one of said first throttle shaft or said second throttle shaft, wherein said end having a magnet to determine a throttle position of said one of said first throttle shaft or said second throttle shaft and wherein said electronic control unit receiving said end of said first throttle shaft or second shaft, said electronic control unit having the other of said magnet;
- and
- a non-transitory, processor-readable storage medium in communication with the electronic control unit, the non-transitory, processor-readable storage medium comprising one or more programming instructions that, when executed, cause the electronic control unit to:
- determine a position of the magnet to determine the throttle position of the one of said first throttle shaft or said second throttle shaft;
- transmit and receive a plurality of data through a remote short range communications module to an external computing device;
- receive inputs from the remote short range communications module in response to the plurality of data;
- and
- in response to the determination of an undesirable position of the magnet, execute at least one of an idle algorithm or a wide-open throttle algorithm to change an operation of the electronic fuel injection throttle body.
