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.

When adapting the system to a new compound, the extruder is initially run with fully open throttle. Should the degassing performance prove insufficient at the desired throughput, the throttle is adjusted in the closing direction.
Once the throttle is shut down, we have to use our dot discipline to make the minute dot correction before the shot is fired.
The capabilities of continuous-time sliding mode control (SMC) [22, 23,24], and discrete-time sliding model control (DSMC) [25, 26], as robust and low-cost nonlinear control design techniques, have been shown in the literature for the throttle control problem.
introduction of the stall probability (ratio of all stalling throttle blips compared to all applied throttle blips in a certain operating point) as an objective measure for comparison
Generally, equivalence ratio and throttle position at a fixed engine speed are representative parameters for any engine operating condition.
During compression, the hydraulic fluid flows from the cavity 3 into the cavity 1 through throttle (calibrated) groove in the valve stem 5 and the gap on valve seat 6, thus overcoming the weak resistance of the internal spring (throttle operation mode).
The flow characteristics of the throttle valve is mainly used in the modeling course.
Unfortunately, outside air temperature, barometric pressure, throttle position, RPM and forward speed are a few of the variables that make it extremely difficult to achieve a quantitative assessment of one filter versus another, in terms of power gains.
The new unit, the first in the world to integrate an air intake throttle valve and an EGR valve, is half the size of conventional models and requires fewer components, thus reducing costs.
Politics Full Throttle also offers a line of political dolls with exaggerated caricature design.
As a result, you'd constantly be adjusting the throttle.
