HORTICULTURE

Detailed explanation-1: -: to decrease the flow of (something, such as steam or fuel to an engine) by a valve. : to regulate and especially to reduce the speed of (something, such as an engine) by such means.

Detailed explanation-2: -The point at which the intake valves close is selected in a way that appears to reduce an engine’s displacement. Engine power output is prevented from falling by opening the throttle, ultimately diminishing throttling losses.

Detailed explanation-3: -When the throttle is opened a small amount, only a small amount of air can enter the engine. This lowers the amount of power the engine can produce and minimizes the speed at which the engine can operate. When the throttle is opened further, more air enters the engine, increasing power output and engine speed.

Detailed explanation-4: -Fuel Flow Rate means flow rate of the fuel, expressed in cubic metres per second at standard temperature and pressure, or kilograms per second.
