Abstract: A pollution control system for a diesel engine includes a PCV valve and an associated vacuum pump having an inlet and an outlet adapted to vent blow-by gas out from a crankcase to an intake manifold on the diesel engine. The vacuum pump associated with the PCV valve selectively modulates vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the crankcase through the PCV valve.

Abstract: A system for reducing polluting emissions of diesel engines includes a hydrogen gas generator that mixes the hydrogen gas with diesel fuel during certain operations phases of the engine. A default program mixes no hydrogen gas with the diesel fuel. A first operational program, during a cold start, mixes the hydrogen gas and diesel fuel in a 1:1 ratio. A second operational program, during a stabilization phase, mixes the hydrogen gas and diesel fuel in a 1:3 ratio. A third operational program, during a hot start phase, mixes the hydrogen gas and diesel fuel in a 1:2 ratio.

Abstract: A retrofit-kit converts an existing internal combustion engine running on gasoline or diesel to run on either the old fuel or an alternative fuel such as compressed natural gas, liquid petroleum, hydrogen, propane, etc. The kit provides a new fuel tank for the alternative fuel, fuel injectors specifically calibrated for the type of alternative fuel used in the kit, as well as gasoline or diesel, and a micro-controller which reads existing engine sensors to allow for fine-tuned injection of the alternative fuel, along with regulation of blow-by gas recycling.

Abstract: A plasma header gasket for use with an internal combustion engine includes plasma-igniters disposed around the perimeter of apertures in the gasket corresponding to piston cylinders in the engine. The plasma-igniters produce a plasma ionization field in time with the engine to increase the efficiency of combustion.

Abstract: A pneumatic fuel pressure regulator and a mechanical fuel pressure regulator are disclosed wherein the pneumatic fuel pressure regulator uses a mechanical adjustment screw to position a spring locator and spring force exerted on a diaphragm assembly controlling flow through a base fuel block. The mechanical fuel pressure regulator includes a stepper motor and a threaded drive shaft to control pressure exerted on a diaphragm assembly to regulate passage through a base fuel block. A dual stage system combines the pneumatic and mechanical regulators in a dual base unit having two ports separately controlled by the separate regulators.
