GAC offers an advanced gaseous-fueled engine management system with exhaust emissions control to meet worldwide standards. The basic Fuel and Ignition Management System (FIMS) is for low-pressure applications using a venturi mixer and stepper motor control valve. The user interface software is completely designed by GAC. The system includes a built-in engine speed governor and two separate modules which can operate stand-alone depending on the application needs. It is extremely cost effective and capable. The compete-system approach results in a cost-effective solution that offers the greatest potential for improvements in both engine efficiency and exhaust emissions.
