Fuel System Upgrade Utilizes XVG with Embedded Fuel Schedules
One of the most effective ways to improve the operation of your industrial engine is to upgrade to a high precision electronic fuel metering valve. Unfortunately, for older machines, this often requires the addition of a costly engine control that is compatible with the new fuel delivery system.
Precision Engine Controls Corporation (PECC) has solved this problem with an innovative option for their XVG line of fuel metering valves. By leveraging the capability of the high powered DSP, the “brain” of the XVG, and utilizing the integral flow measurement capability, PECC’s applications group developed a process for embedding the fuel control schedules directly into the valve itself.
This technique allows the valve to regulate fuel flow from light-off up to idle speed. Once idle speed is reached the valve electronics transition over to the older engine control’s demand signal allowing for seamless loading and unloading of the engine.
This “flow limiting” mode has been successfully demonstrated at a large oil and gas company in Southern California where the system is now in continuous operation. Upgrading to the modern fuel system has virtually eliminated the starting inconsistencies that plagued this site and removed the older, high maintenance components from the installation. Furthermore, since the XVG requires no additional modifications to interface with a PLC, the valve provides an excellent building block for future control upgrades - should the operator decide to move in that direction at a later date.
