Fuel primer pump - A manual pump to add a small amount of fuel at the cylinder intakes to assist in starting a cold engine. Fuel-injected engines do not have this control. For fuel-injected engines, a fuel boost pump is used to prime the engine prior to start. Fuel quantity gauge - Indicates the amount of fuel remaining in the identified tank ...
A throttle body is somewhat analogous to the carburetor in a non-injected engine, although it is important to remember that a throttle body is not the same thing as a throttle, 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.
A tube ensures flow of oil from the reservoir to the oil pump. This system is commonly used for motorcycles as it eliminates the need of pre-mixing fuel and two-stroke oil. Vespa is an example where pre-mixing of two-stroke oil is required. Automatic lubrication was introduced for motorcycles by Velocette in 1913. [1] An example of application ...
Thrust levers of an A320 set to the autothrust position during cruise flight. An autothrottle (automatic throttle, also known as autothrust, A/T or A/THR) is a system that allows a pilot to control the power setting of an aircraft's engines by specifying a desired flight characteristic, rather than manually controlling the fuel flow.
The rate of airflow through an internal combustion engine is an important factor determining the amount of power the engine generates. Most gasoline engines are controlled by limiting that flow with a throttle that restricts intake airflow, while a diesel engine is controlled by the amount of fuel supplied to the cylinder, and so has no "throttle" as such.
Thrust levers in a Boeing 747 Classic. The center and rear levers are used during flight, while the forward levers control reverse thrust.. Thrust levers or throttle levers are found in the cockpit of aircraft, and are used by the pilot, copilot, flight engineer, or autopilot to control the thrust output of the aircraft's engines, by controlling the fuel flow to those engines.

Throttling a running engine back to reduce revs was possible by closing off the fuel valve to the required position while re-adjusting the fuel/air mixture to suit. This process was also tricky, so that reducing power, especially when landing, was often accomplished instead by intermittently cutting the ignition using the blip switch.
The advent of concern about fuel economy and emissions had major impacts on engine design. Some of the trade-offs reduced throttle response. Most new cars employ a drive-by-wire system, which includes electronic throttle control and can itself either reduce or increase throttle response (Depending on whether or not it's being employed on a performance car).
