Abstract
An enhanced pressure-wave supercharger for a combustion engine utilizes a superior pressure wave process cycle design. The design utilizes a select final portion of the compressed gas stream exiting the rotor, and supplies it to a subsequent inlet port ahead of and prior to the introduction into the rotor of the aspirated air to be compressed. Work is extracted within the rotor from this gas stream and transferred into rotational energy of the rotor through using a portion the available momentum of the compressed gas via incidence on the rotor webs to turn the rotor by means of conventional turbomachinery principles.

An enhanced pressure-wave supercharger for a combustion engine, comprising:
- at least one housing assembly comprising a first portion and a second portion, wherein said first portion is configured to generate pressurized gas to be supplied to said engine;
- a plurality of channels, wherein a first channel is configured to direct exhaust gas from the combustion engine towards said housing, a second channel is configured to draw in air from an external environment, a third channel configured to direct and discharge the exhaust gas from said housing, a fourth channel configured to supply a first portion of pressurized gas from the housing to the combustion engine, and a fifth channel, located after the fourth channel and before the second channel, with respect to direction of rotation, wherein the fifth channel is configured to direct pressurized gas from said housing back into said housing to generate rotational energy to at least one rotor disposed within said housing, wherein said fifth channel comprises a work extracting device, a bypass inlet and a bypass outlet passage, wherein said bypass inlet is configured to direct a second portion of pressurized gas from inside said first portion of the housing back into said second portion of the housing through the bypass outlet passage.
An enhanced pressure-wave supercharger for a combustion engine, comprising:
- at least one housing assembly, comprising:
- a first portion and a second portion, wherein said first portion is configured to generate pressurized gas to be supplied to said engine;
- a plurality of channels configured to direct gas towards and from said housing, comprising:
- a first channel configured to supply exhaust gas from the combustion engine;
- a second channel configured to draw in air from an external environment;
- a third channel configured to discharge exhaust gas from the supercharger;
- a fourth channel configured to supply a first portion of pressurized gas from the supercharger to the combustion engine;
- a fifth channel having a work extracting device, a bypass inlet and a bypass outlet passage, wherein said bypass inlet is configured to direct a second portion of pressurized gas from inside said first portion of the housing back into said second portion of the housing through the bypass outlet passage;
- and
- at least one rotor disposed within said housing, wherein said second portion of pressurized gas is configured to increase rotational energy to turn said rotor.
A method of efficiently driving a pressure wave supercharger comprising:
- providing a pressure wave rotor assembly having a rotatable rotor within a housing and a plurality of passageways for the passage of gas therethrough;
- compressing air with an enhanced pressure wave supercharger, wherein an exhaust gas channel connects a combustion engine to the pressure-wave supercharger, wherein exhaust gas from the combustion engine is used to power the pressure-wave supercharger, an outlet channel is connected from the pressure-wave supercharger to the engine, an air inlet channel connected to the pressure-wave supercharger, and outlet channel connected to an exhaust system to the pressure wave supercharger, a bypass channel connected to two portions of the enhanced pressure wave supercharger wherein said bypass channel includes a work extracting device, and a gas inflow valve for increasing and decreasing gas flow through the exhaust gas channel;
- and
- creating a compression flow stream and using the bypass channel to more efficiently drive said supercharger, wherein said bypass channel is configured to direct pressurized gas from inside a first portion of the housing back into a second portion of the housing through a bypass outlet passage;
- and increases rotational energy to turn said rotor and increase pressure of gas travelling through the outlet channel.
