What components make up a jerk pump fuel injection system?

A jerk pump fuel injection system is primarily composed of high-pressure pumps and separate spray valves. In this system, the high-pressure pumps are responsible for generating the necessary pressure to deliver fuel to the injectors. This pressure is crucial for ensuring that the fuel is injected into the combustion chamber at the correct time and in the proper quantity for efficient combustion.

The separate spray valves, also known as injectors, receive the high-pressure fuel from the pump and atomize it, creating a fine mist that allows for better mixing with air and more efficient combustion within the engine cylinders. The design of the jerk pump system allows for precise control over the amount of fuel injected, which is essential for maintaining optimal engine performance and fuel efficiency.

This understanding of the components highlights their vital roles in the functioning of the fuel injection system, reinforcing why high-pressure pumps and separate spray valves are integral to the operation of a jerk pump system.
