Abstract
An internal combustion system and a water injection nozzle to position a water mist within an internal chamber of an internal combustion engine. In one form, the apical cone of the injection is altered with respect to the position of the piston within the interior chamber. In another form, the air fuel mixture is charged at an opposing charge to the water mist to create a water droplet gaseous fuel mixture for combustion within the anterior chamber.
