Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor. But just opening or closing the throttle valve by sending a new signal to the electric motor is an open loop condition and leads to inaccurate control.
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.
The Yamaha TX500 is a two-cylinder standard motorcycle built by Yamaha and sold in 1973 and 1974. Early models closely resembled the Triumph Bonneville in style. In 1975 the bike was renamed XS500 and then continued to be updated until 1978 when sales ended in the USA.
Historically, the throttle pedal or lever acts via a direct mechanical linkage. The butterfly valve of the throttle is operated by means of an arm piece, loaded by a spring. This arm is usually directly linked to the accelerator cable, and operates in accordance with the driver action.
Therefore, an accelerator pump is often used to briefly provide extra fuel as the throttle is opened. [12] When the driver presses the throttle pedal, a small piston or diaphragm pump injects extra fuel directly into the carburetor throat. [13] The accelerator pump can also be used to "prime" an engine with extra fuel prior to attempting a cold ...
A Bowden cable (/ ˈ b oʊ d ən / BOH-dən) [1] is a type of flexible cable used to transmit mechanical force or energy by the movement of an inner cable relative to a hollow outer cable housing. The housing is generally of composite construction, consisting of an inner lining, a longitudinally incompressible layer such as a helical winding or ...
It was a simple two button, three axis joystick. It featured a trigger button, a thumb button and a throttle wheel on left side of the base. In addition it had two additional dials on the base for adjustment of the stick itself, one above stick and the other to the right of the stick. It used a gameport connector to interface with the computer.
The TU250x had a twin valve, single cylinder engine with a closed-loop [8] Electronic Fuel Injection (EFI) system (marketed as Suzuki Dual Throttle Valve) and a 32-bit ECU, [8] oxygen sensor, catalytic converter, integral cold-start system, [8] 32mm throttle body [8] 10-nozzle injector and a proprietary air injection system (marketed as Suzuki ...
