Abstract
An intake plenum has a bottom and a continuous side wall. The plenum has at least one tube opening there into. There is at least one intake tube, with each tube having an inflow end and an outflow end. Each inflow end is coupled to a plenum tube opening. There is a plenum airflow regulator housed within the plenum. There is at least one fuel injector.
Claims15
An air intake system, comprising:
- an intake plenum having a bottom and a continuous side wall, the plenum having at least one tube opening there into, the plenum comprising an air passageway;
- at least one intake tube, each tube having an inflow end and an outflow end, each inflow end coupled to a plenum tube opening;
- a slidably mounted plenum airflow regulator having an associated biasing spring housed within the plenum the spring biasing the regulator in a substantially air passageway occluding position;
- at least one fuel injector coupled to an intake tube.

An air intake system, comprising:
- an intake plenum fabricated of a rigid material having an upper superior portion and a lower inferior portion, the plenum having a generally round cylindrical tubular configuration forming an air Passageway therein, with the plenum having a bottom and a continuous side wall, the bottom of the lower portion of the plenum having a lower surface and an upper surface with a thickness there between, the bottom of the lower portion of the plenum having a tension shaft aperture there through, the side wall of the plenum having an inner surface and an outer surface with a thickness there between, the plenum side wall having a plurality of tube openings there into, the tube openings having an associated coupling means;
- a plurality of intake tubes fabricated of a rigid material, each intake tube having a generally round tubular hollow configuration, with each tube having a smooth inner tube wall, with each tube having an equal length and within a length variance of between about 0.001 inch and 1.00 inch, each tube having an inflow end and an outflow end, each inflow end having a coupling means so as to allow the intake end of each tube to be coupled to a plenum side wall tube opening, the outflow end of each tube having an coupling means, each tube having a fuel injection port, with the port being located within one-third of the length of the tube from the outflow end of the tube;
- a plenum airflow regulator having a generally hemispherical configuration having a rounded superior top surface and a flat inferior bottom surface, the rounded superior top surface of the airflow regulator being configured and sized to mate with and to substantially occlude the lower portion of the plenum, the inferior bottom surface of the airflow regulator having an associated spring tension shaft and an associated coiled spring, with the spring having a plurality of coils and the spring being positioned so that the tension shaft passes through all the coils of the spring, with the tension shaft being coupled to the lower portion of the plenum, with the tension shaft also passing through the tension shaft aperture of the lower portion of the plenum, with the spring being contained between the inferior surface of the airflow regulator and the inner bottom surface of the plenum;
- a plurality of fuel injectors with a fuel injector being coupled to the fuel injection port of each of the intake tubes, each fuel injector having an associated fuel supply line coupled there to and each fuel injector having a control means coupled there to.
