409:. The throttle is either open or closed (although there is always a small hole or other bypass to allow a small amount of air to flow through so the engine can idle when the throttle is closed), or some intermediate position. Since air velocity is crucial to the functioning of a carburetor, to keep average air velocity up, larger engines require more complex carburetors with multiple small venturis, typically two or four (these venturis are commonly called "barrels"). A typical "2-barrel" carburetor uses a single oval or rectangular throttle plate, and works similarly to a single venturi carburetor, but with two small openings instead of one. A 4-venturi carburetor has two pairs of venturis, each pair regulated by a single oval or rectangular throttle plate. Under normal operation, only one throttle plate (the "primary") opens when the accelerator pedal is pressed, allowing more air into the engine, but keeping overall airflow velocity through the carburetor high (thus improving efficiency). The "secondary" throttle is operated either mechanically when the primary plate is opened past a certain amount, or via engine vacuum, influenced by the position of the accelerator pedal and engine load, allowing for greater air flow into the engine at high RPM and load and better efficiency at low RPM. Multiple 2-venturi or 4-venturi carburetors can be used simultaneously in situations where maximum engine power is of priority.
526:" or ITBs. Although rare in production vehicles, these are common equipment on many racing cars and modified street vehicles. This practice harks back to the days when many high performance cars were given one, small, single-venturi carburettor for each cylinder or pair of cylinders (i.e. Weber, SU carburettors), each one with their own small throttle plate inside. In a carburettor, the smaller throttle opening also allowed for more precise and fast carburettor response, as well as better atomization of the fuel when running at low engine speeds.
608:. They are also useful in situations where the airspeed of the vehicle must be limited due to aerodynamic stress in the denser atmosphere at lower levels (e.g. the Space Shuttle). Rockets characteristically become lighter the longer they burn, with the changing ratio of thrust:weight resulting in increasing acceleration, so engines are often throttled (or switched off) to limit acceleration forces towards the end of a stage's burn time if it is carrying sensitive cargo (e.g. humans).

A steam locomotive throttle valve poses a difficult design challenge as it must be opened and closed using hand effort against the considerable pressure (typically 250 psi or 1,700 kPa) of boiler steam. One of the primary reasons for later multiple-sequential valves: it is far easier to open a small
456:, and that carbureted engines have throttles as well. A throttle body simply supplies a convenient place to mount a throttle in the absence of a carburetor venturi. Carburetors are an older technology, which mechanically modulate the amount of air flow (with an internal throttle plate) and combine air and fuel together (

The lifespan of the throttle is not set since it highly depends on the driving style and specific vehicle. The throttle tends to be quite dirty after 100-150 thousand kilometers, and it is necessary to clean it up. The malfunction of the throttle could be indicated by illuminated EPC warning light.
