  • Patent number: 11486295
    Abstract: The invention involves a system and method for providing a liquid fuel or a liquid and gaseous fuel to a diesel or Otto cycle engine for operation of the engine. The system includes a primary electronic control module (ECM), which monitors engine sensors and contains a first three-dimensional fuel map for the liquid fuel. A second ECM is connected for bi-directional transfer of information to the first ECM, the second ECM contains a second three-dimensional fuel map for delivery of the gaseous fuel through a secondary gaseous fuel injection assembly. The bi-directional communication between the two ECMs while monitoring the engine sensors allows both ECMs to “learn” an efficient fuel map for delivery of both fuels in the same cycle for improved efficiency, reduction in slip and lower emissions.

  • Patent number: 7841322
    Abstract: The instant invention provides an apparatus and system for cooling the air charge of an internal combustion engine. More specifically, the instant invention provides an air-induction system suitable to provide cooled air charges to turbocharged, supercharged or naturally aspirated internal combustion engines to increase power output while reducing engine emissions. The system utilizes gaseous fuel stored as a liquid wherein the liquefied gaseous fuel is vaporized and warmed at least partially with heat removed from the intake air charge supplied to the engine from the turbocharger or supercharger. In a preferred embodiment, the compressed intake combustion air is first cooled in an aftercooler against an ambiently cooled coolant and is subsequently cooled further by the chiller of the instant invention which utilizes the change in phase, between liquid and gas, of the alternative fuel to cool the incoming air charge.

  • Patent number: 7100582
    Abstract: A propane injector system for internal combustion engines for improving performance, fuel efficiency, safety, cleanliness and environmental friendliness. The system consists of introducing propane gas into “a black box” that has a pressure reducing valve to drop propane pressure as it flows initially from its storage tank and through an electronically controlled on/off valve. Propane enters an injector manifold where it is distributed to two specially designed gas handling fuel injectors that act as variable flow rate pumps controlled by a programmable microprocessor that is pre programmed for specific vehicles or can be customized with improved performance programming as determined by the vehicle owner. A pressure feedback system senses when the engine blower has caused a pressure boost on its high side feeding the cylinders. Transducers located in a Manifold Absolute Pressure (MAP) sensor detect the pressure boost and communicate with the microprocessor.
