Book excerpt: Current heavy duty natural gas engines rely on elementary fuel metering systems. To improve the efficiency and reduce emissions of these engines, a more sophisticated fuel delivery system is required. One approach is the use of a gas valve for injection of natural gas into the intake ports. This project evaluated an existing solenoid valve and three prototype valves. The valves tested were a production solenoid operated valve manufactured by Servojet Products Inc., a prototype solenoid operated valve developed by Ortech International, a prototype continuous flow valve sized for one cylinder developed by B.C. Research, and a prototype continuous flow valve sized for an entire engine developed by B.C. Research, to be used with a fuel delivery manifold, or spider'. The results are graphed and discussed.
