throttle

1. any device that controls the quantity of fuel or fuel and air mixture entering an engine
2. an informal or dialect word for throat

Throttle

 

a device whose cross section is considerably smaller than that of the pipeline leading to it. A throttle regulates the flow rate and changes other parameters (temperature, humidity, and superheating) of a working body flowing in a closed channel.

Throttles are mounted in front of a steam turbine to control loading by throttling the steam; in high-pressure steam lines they are used to reduce pressure at the point where the steam enters a low-pressure steam line (for example, in heating systems). They are also used in compressors and blowers to decrease the pressure of the gas at the intake and in refrigerators to expand the compressed gas in order to cool it. One type of throttle is an accelerator, which controls the supply of the fuel mixture to the cylinders of internal-combustion engines.

throttle

The control in an aircraft engine that regulates the power or thrust the pilot desires the engine to develop. It is basically a control unit, which controls the amount of fuel or the fuel-air mixture that can enter the engine. It is controlled by a throttle lever in the cockpit. This lever is referred to colloquially as a throttle. Also called a power lever or a thrust lever. See throttle friction nut.

throttle

To cause something to slow down or speed up. When automobiles first emerged at the turn of the 20th century up until the 1940s, they used to have a throttle. It was a lever that increased the engine speed as it was pulled out. See CPU throttling, throttled transfer and bandwidth throttling.

Next, a simplified nonlinear model for the throttle dynamics will be presented.
All investigations have been conducted in idling operation as this can be considered the worst case situation for fast throttle transients because of the low engine speed and therefore the low kinetic energy of the crank train.

The air intake throttle valve and EGR valve are connected through a highly flexible coupling (cam-link mechanism), allowing the new unit to be applied to various engine parameters, including displacement and output, merely by changing the shape of the connection between the two valves (cam profile).
The earliest internal combustion engines required the operator to adjust the throttle in response to the load.

Run the engine at varied throttle settings between 3000 and 4500 rpm or three-quarter throttle, changing engine speed every two minutes.
An extremely important phenomenon which takes place while using these resistors is the heating of the liquid, which leads to a modification of the viscosity and implicitly of the flow that goes through the throttle.
The new throttle pedal is available with both contact and noncontact sensors and sensor outputs that include single analog, single analog with switch, dual analog and PWM as well as customer specific outputs.
