EMISSIONS REQUIREMENTS The ECV 5 valve offers full authority fuel control for almost any size of gas engine. The variable pressure control technique allows for fast acting control that can include single setpoint steady state control, or, where emissions requirements are extremely low, it can provide mapped load versus fuel input, or even dithering around a dynamic setpoint to optimize the performance of the three-way catalyst. THE SOLUTION Altronic offers a complete system that will maintain the emissions levels of all gas engines in compliance with the most severe local, state, and federal emissions regulations, while maintaining peak operating efficiency. Ideally the ECV 5 will be used to control fuel pressure to an Altronic mixing venturi to achieve the lowest possible emissions under all load conditions. The ECV 5 can also be used as the primary fuel valve controlling fuel to the carburetor on an aftermarket AFR installation. The ECV 5 is basically an electronic variable pressure regulator that will vary the fuel pressure to the engine based on a load input and/or an input from a Wide Band Oxygen Sensor. The ECV 5 also can accept an input from the Catalyst Monitor via Can Bus to dynamically adjust the O2 Sensor setpoint based on changing sensor or catalyst conditions. Venturi will automatically accommodate the change by allowing the precise amount of fuel for the amount of air to the engine. No mechanical action is required to make this fuel adjustment.
