Final answer:
The component that supplies high-pressure fuel for combustion in an internal combustion engine is the fuel injector, which operates by injecting fuel during the intake stroke to mix with air for efficient combustion.
Step-by-step explanation:
The component that supplies high-pressure fuel for combustion and motive flow operation in an internal combustion engine is the fuel injector. In this context, we are dealing with the four-stroke internal combustion engine used in most automobiles. Let us examine how this works:
- (a) Intake stroke: The air is mixed with fuel during the intake stroke.
- (b) Compression stroke: The air-fuel mixture is compressed, raising the pressure within the cylinder.
- (c) Power stroke: Upon ignition of the air-fuel mixture, chemical potential energy is converted to thermal energy, significantly increasing the pressure, which then pushes the piston to do work.
- (d) Exhaust stroke: The exhaust stroke removes the spent gases to allow the cycle to begin again with the intake stroke.
The high-pressure fuel for combustion is provided by the fuel injector during the intake stroke, ensuring that there is a precise mixture of fuel and air for the engine's operations.
