What is the primary purpose of the fuel metering section in the Bendix/Precision fuel injection system?

Reduce fuel flow during idle

Mix fuel with air in the combustion chamber

Meter and control the fuel flow to the flow divider

The primary purpose of the fuel metering section in the Bendix/Precision fuel injection system is to meter and control the fuel flow to the flow divider. This section plays a crucial role in ensuring that the correct amount of fuel is delivered to each cylinder, which is essential for efficient engine performance and operation. By accurately regulating fuel flow based on various engine operating conditions, the fuel metering section contributes to optimal combustion, helps maintain the desired air-fuel ratio, and supports overall engine efficiency.

In this context, the flow divider receives the metered fuel and distributes it evenly to the individual injectors for combustion. This precise control is vital to ensure that the engine receives the necessary fuel for varying power requirements, enhancing performance and reducing emissions.
