Abstract:
1. A system for controlling exhaust emissions from a compression ignition engine capable of using multiple fuels drawn from at least two separate fuel storage tanks, the system comprising: a crankshaft position sensor (CPS) for detecting a predetermined position of a crankshaft of the engine and sending a time signal when the position is detected, an electronic control module (ECM) for receiving an original time signal (T an electronic phase adjustor module for intercepting the original time signal (T wherein the electronic phase adjustor is adapted to generate a revised time signal (T so that when the engine is running on 100% alternative fuel, or 100% mixture of alternative fuel and No. 2 diesel or petroleum diesel fuel, one or more harmful emissions are minimized and reduced to a level substantially equal to or lower than a level of the one or more harmful emissions when the engine is running on only 100% No. 2 diesel or 100% petroleum diesel fuel.
