Where is the injection valve on a meter?
Where is the injection valve on a meter?
Injection valves are mounted at the point of injection to connect the metering line. They protect against backflow and generate a defined back pressure.
How does the fuel metering valve work on a fuel pump?
To adapt the fuel pressure in the rail, the fuel metering valve on the mechanical fuel pump controls the amount of fuel entering the pump. The plunger is held fully open by a spring to let fuel pass through.
What is an ultrasonic chemical injection metering valve?
Sign up for news PULSE ultrasonic chemical injection metering valves (CIMVs) are remotely operated, ROV-retrievable, self-regulating subsea chemical injection metering systems.
How does low fuel pressure affect fuel metering?
This low fuel pressure causes the ECU to drive the fuel metering valve with a high duty cycle signal. Once the engine is running the mechanical fuel pump starts to work, which increases the fuel pressure.
Injection valves are mounted at the point of injection to connect the metering line. They protect against backflow and generate a defined back pressure.
How is the plunger on a fuel metering valve controlled?
The plunger’s position is controlled by the ECU, based on the required engine output and the current fuel pressure measured by the fuel pressure sensor. The fuel metering valve solenoid is powered from a system relay on the positive side and the ECU switches the negative side to the ground.
What is the chemical injection metering valve fluidcom?
Inaccurate and unstable dosing of chemicals is a well-known problem in the oil and gas upstream sectors. To solve such problems, we introduce our Chemical Injection Metering Valve, FluidCom. With use of FluidCom, the injecation rate can be controled stably and accurately.
Where is the check valve on a fuel injector?
A gasket or silicone seal must be used on the bottom of the injector. This metering system uses two return lines, each with a check valve. The check valve on the bottom of the metering valve is for the idle circuit and is set to open at 25 psi.
