ABSTRACT:
A water injection system (WIS) for diesel engines that reduces NOx, PM and CO2emissions is provided. Water is injected into the combustion air stream before cylinders in a predetermined proportion to fuel. The present invention utilizes a special water purification element, an oscillating pump, an electronic means to control both water flow and the size of water droplets, a means to prevent water from freezing in cold ambient temperatures, a plurality of special sensors to control water flow in response to rapid load variation, and a means for automatically switching between on and off operations.
