Air Only Patents (Class 123/556)
  • Patent number: 9664151
    Abstract: An air admission device for combustion equipment includes a hollow tubular housing having two ends respectively provided with an air intake and an air outlet. The housing has its interior provided with a plurality of partition boards spaced apart and respectively bored with at least one air hole, the air holes of adjacent partition boards being staggered in arrangement. The air admission device is connected to combustion equipment. When operated, the combustion equipment will produce negative pressure to guide outside air to get into the housing to dash against the partition boards to increase collision probability between gas molecules for enhancing kinetic energy of gas molecules via collision and friction, thus attaining combustion-supporting effect, making combustion more complete and lowering waste gas emission.

  • Patent number: 9534560
    Abstract: A non-compression engine having two or three variable volume mechanisms, an induction-displacer (1) and a combustion-expander (2) or an induction-displacer (1) and a combustion-expander (2) and an atmospheric-cooler (3). A working volume of gas is drawn into the induction-displacer, then displaced into the combustion-expander (2) at substantially constant volume passing through the regenerator (5). The gas in the combustor-expander (2) is further heated by combustion of a fuel then expanded to extract work. The gas is then displaced through the regenerator (5) into the atmospheric-cooler (3) at substantially constant volume, or exhaust from the regenerator at constant pressure. The gas is contracted in the atmospheric-cooler doing atmospheric work. Once the gas has equilibrated with the pressure of the atmosphere it is exhaust from the atmospheric-cooler (3).

  • Patent number: 9404401
    Abstract: In a method for operating a forced-induction internal combustion engine of a motor vehicle with variable compression, provision is made that the variable compression is pilot-controlled in such a way that a selected compression is established as a function of combustion efficiency and of the mechanical stress on components of the internal combustion engine, such that elevated compression is provided in the naturally aspirated range and/or decreased compression is provided in the forced-induction range. The variable compression is generated by phase shifting of a camshaft of the internal combustion engine, or by cam switching by way of a variable valve train.

    Abstract: Disclosed is an intake pipe for a combustion engine, comprising a housing (1) with a supply duct (2) for especially compressed air, a heat exchanger (8) which is disposed within a main duct (4) in the housing (1) and through which the air can flow in order to exchange heat with a fluid, and a bypass duct (5) that is separated from the main duct (4) in at least some sections and is fitted with at least one positioning element (7) to allow the fed air to adjustably bypass the heat exchanger (8). An end of the bypass duct (5) on the engine side is placed at a still flow-relevant short distance from an opening (11) of an intake valve (10) of the combustion engine.

  • Publication number: 20100242926
    Abstract: A fuel heating apparatus for an internal combustion engine or other type of spark ignition engine having an associated pressurised fuel delivery system, the apparatus comprising a chamber for receiving a volume of a pressurised liquid fuel; and means for heating the fuel within the chamber to provide heated liquid fuel to the fuel delivery system of the engine, to thereby minimise condensation of the fuel and facilitate ignition of the engine within relatively low ambient temperature environments. The apparatus has particular application with ‘heavy fuels’, such as diesel or kerosene, and improves the reliability and performance of the engine especially during ‘cold starts’ and while transitioning to fast-idling.

  • Publication number: 20100199931
    Abstract: In an internal combustion engine (2) of a portable handheld work apparatus, the cylinder (3) is provided with cooling ribs (4, 4?). A cooling airflow is generated by the fan wheel (13) and is guided over the cooling ribs. A carburetor (9) is temperaturized as required by the heated cooling air. A control of the cooling airflow to the carburetor (9) takes place in that an opening (11), which passes the heated cooling air, is selectively closed or opened via a closure element (12). In order to obtain improved cooling of the cylinder during summer operation as well as during winter operation, the closure element (12) is provided with at least one air guide wall which extends essentially transversely to the cooling airflow and causes this cooling air to be partially backed up and deflected.

  • Patent number: 7757674
    Abstract: A V-twin engine having a crankcase and a pair of cylinders defining a V-space therebetween, wherein the V-space is substantially enclosed, and a carburetor is positioned within the V-space. An intake air preheating arrangement supplies heated intake air to the carburetor, and a carburetor heating arrangement heats the V-space and the carburetor which is positioned within the V-space. Each of the foregoing arrangements, used separately or in combination within one another, aids in preventing “freeze-up” of the carburetor during running of the engine in a cold environment.

  • Patent number: 7717097
    Abstract: According to the method, the gases are circulated in a liquid/gas heat exchanger (2, 12) prior to their entering the internal combustion engine (58) and a high temperature liquid and/or a low temperature liquid is circulated in the liquid/gas heat exchanger (2, 12) in order to heat and/or cool the gases (84) as required. The liquid/gas heat exchanger may comprise a single stage or two stages, that is a high temperature stage and a low temperature stage. It can also be used to cool the recirculating exhaust gases prior to their entering the engine.

  • Patent number: 7665442
    Abstract: A throttle plate for use with internal combustion engines comprised of a relatively thin piece of material so that installation of the throttle plate between the carburetor or throttle body and intake manifold of a vehicle does not require additional brackets or components to correct throttle cable linkage length or geometry. The throttle plate comprises a plate having apertures to accommodate pre-existing connectors and a perimeter that corresponds to connections between, and the geometry of, the carburetor or throttle body and intake manifold. The plate fits between the carburetor or throttle body and intake manifold and defines at least one airflow hole corresponding to the airflow path in the carburetor or throttle body. If there are multiple airflow paths between the carburetor or throttle body and intake manifold, then there will be multiple airflow holes. One or more vanes integral with the plate extend radially from the perimeter of each airflow hole toward its center.

  • Publication number: 20100006073
    Abstract: Most of the cars in today's market give a maximum of 30 to 40 miles per gallon and hybrid cars giving upto 50 miles per gallon. The efficiency of Internal Combustion Engines used for this purpose is very low, about 25%. The heat generated during the combustion of fuel is converted into work to drive the car is wasted to the atmosphere, as anti-freeze(Ethylene Glycol) is used to cool the engine and circulated through a radiator which transfers the heat to the atmosphere. The heat generated by combustion of fuel such as gasoline or diesel is converted into the work because of the pressure created by the combustion process. In this invention, the heat is recovered by pre-heating/pressurizing the fresh air used for the process of combustion. The temperature of the pre-heated fresh air used for combustion is increased to above 1400 degrees Fahrenheit by passing through a heat exchanger to recover heat from combustible gases. Fresh air for combustion is heated to about 1400 degrees Fahrenheit.
