Abstract
A system and method for retrofitting a fuel delivery system of vehicle having internal combustion engine is disclosed. The system allows delivery of nitrous oxide in a dense liquid form from a nitrous oxide bottle directly to each of the engine cylinders. A cooling unit is mounted between the nitrous oxide bottle and the engine so as to retain the nitrous oxide in a cold liquid condition. A nozzle assembly that introduces the nitrous oxide and engine fuel into a cylinder has a reduced size orifice, in the order of 0.01-0.05″.
Claims28
A nitrous-oxide system for an internal combustion engine having a fuel line, the system comprising:
- a closed container with nitrous oxide under pressure;
- a first conduit connected to the container and configured for delivery of nitrous oxide from the container;
- a cooling unit mounted downstream from the first conduit, said cooling unit comprising a hollow cooling tubing fluidly connected to a free end of the first conduit, said cooling unit being configured to retain a cooling medium in a surrounding relationship to the cooling tubing;
- a second conduit connected to an outlet end of the cooling tubing;
- and
- a nozzle assembly, operationally connected to the second conduit and operatively coupled to an engine intake;
- said nozzle assembly comprising a jet nozzle fitting configured to inject a mixture of nitrous oxide and fuel into the engine intake.
A nitrous-oxide system for an internal combustion engine having a fuel line, the system comprising:
- a closed container with nitrous oxide under pressure;
- a first high pressure conduit connected to the container and configured for delivery of nitrous oxide from the container;
- a cooling unit mounted downstream from the first conduit, said cooling unit comprising a hollow coiled tubing fluidly connected to a free end of the first conduit, said coiled tubing being configured for transporting the nitrous oxide from said first conduit at a temperature of at or below 0° C., said cooling unit being configured to retain a cooling medium in a surrounding relationship to the coiled tubing;
- a second conduit connected to an outlet end of the cooling tubing;
- and
- a nozzle assembly, operationally connected to the second conduit and operatively coupled to an engine intake;
- said nozzle assembly comprising a jet nozzle fitting configured to inject a mixture of nitrous oxide and fuel into the engine intake.
A method for retrofitting an engine of a gasoline powered vehicle having an internal combustion engine with a nitrous-oxide system, comprising the step of:
- providing a source of pressurized nitrous oxide;
- providing a nozzle assembly coupled to the source of nitrous oxide and positioning the nozzle assembly in fluid communication with a fuel line of each cylinder of the internal combustion engine;
- providing a cooling unit between the source of nitrous oxide and the nozzle assembly, said cooling unit maintaining temperature of nitrous oxide at or below 0° C.
