摘要:
An injection/mixing device for improving the mixing of fuel and air in a petrol driven internal combustion engine. The device is fitted in the engine inlet manifold close to the fuel inlet from a carburettor or fuel injector and uses a vortex generator. The vortex generator is in the form of an array of lenticular, conical or deltoid disks located in the fuel/air flow and which serve to disperse the impinging fuel droplets and mix the fuel and air. The effect of the device is preferably enhanced by allowing the vortex generator to rotate or spin about its axis. This rotation is achieved by means of a turbine associated with the disks or by means of an external motor. The device may also be connected to a vacuum relief valve to attenuate the level of the depression in the intake manifold under certain conditions. The vacuum relief valve may be integral or separate from the device.

Disclosed herein is an emission control device for use with a carburetor having a base and at least one fuel opening defined in its base. The device is comprised of a body member of predetermined thickness and defining therein at least one through opening. The through opening communicates with the fuel opening in the carburetor. The device also has an air passageway largely defined in its surface. The air passageway communicates with the through opening. The passageway lies generally adjacent the carburetor and the fuel opening so that air passed through the passageway passes into the through opening and under the fuel opening.
摘要:
A control system for internal combustion engines adapted to take in ambient air and mix it with waste gases from a crankcase to form a molecular comburent mixture to aid in combustion. The system includes a housing mounted between the crankcase and the engine manifold that both forms the comburent mixture and regulates the introduction of the same into the engine manifold.

There is described a method of and a fuel economizer device for reducing the fuel comsumption of an internal combustion engine. The device is in the form of a body having an outlet to the engine and a pair of inlets for admission of additional air. The inlets are controlled by pressure operated valves.
摘要:
A device for correcting the combustion of internal combustion engines, in particular automobile engines, the internal combustion engine having an intake manifold, the device including a first sealed chamber directly connected to the intake manifold, a second sealed chamber separated from the first chamber by a diaphragm having a neutral position, the second chamber being connected to the first chamber through a passage for delaying transmission of pressure variations from the first chamber to the second chamber, a control device for reducing the fuel to air ratio of the air and fuel mixture, the control device being coupled to the diaphragm for activation by the diaphragm whenever the differential pressure between the first and second chambers exceed a first predetermined value and whenever the differential pressure exceeds a second predetermined value.
摘要:
An internal combustion engine for a vehicle has an exhaust gas recirculating system for returning exhaust gases to the engine intake passage. The carburetion system for the engine includes a fuel enrichment valve. Sensors for various vehicle speeds and engine operating conditions operate control valves whose actions are modified by a sensor for atmospheric pressure, to control the fuel enrichment valve and a valve in the recirculation passage so that fuel enrichment and exhaust gas recirculation are both reduced when the vehicle travels at a high elevation having low atmospheric pressure.

An air-fuel mixture control valve assembly for automotive vehicles comprises a valve member which is capable of controlling the opening-closing operation of an air admission passage connected to an intake manifold and a one-way disc valve which is disposed in the air admission passage to prevent the possible adverse current of a high pressure and high temperature fluid within the valve assembly, whereby the air is supplied to the intake manifold upon the sudden deceleration of the vehicle to thereby prevent possible generation of various pollutants.

In a first air flow circuit filtered ram air cooperating with an aspirator draws crankcase vapors from the crankcase of an internal combustion engine. Heavy particulate matter in the crankcase vapor is heated and further vaporized by a heat exchanger cooperating with an exhaust manifold of the engine. A second aspirator draws the vaporized particulate matter back into the original vapor steam of the first air flow circuit. The crankcase vapors mixed with the incoming ram air are then directed into the interior cavity of the carburetor air filter. In a second air flow circuit filtered ram air is directed into the crankcase and carburetor air filter cavity and in a third air flow circuit filtered air is drawn through a variable annular orifice and metered in accord with intake manifold pressure and directed into the engine air intake system below the carburetor throttle plate.

A vacuum-operated, pressure-responsive valve is adapted for connection to the intake manifold of an internal combustion engine for monitoring supplemental airflow to the engine, the improvement of the present device providing precise adjustment of the supplemental airflow/intake manifold pressure relationship. An air cylinder, a pressure-responsive piston/valve mounted therein, a threadably mounted axially extending stem and valve-biasing spring, and a resiliently deflectable plate are assembled and cofunction to provide precision click stop adjustment of the supplemental airflow/engine vacuum relationship.
摘要:
Engine performance is improved and nitrogen compound emission is reduced by introducing supplemental air to the intake manifold of an internal combustion engine which is fitted with a PCV valve. The supplemental air inlet device is connected so that it introduces air into the line between the PCV valve and the intake manifold. That line connects to the manifold immediately downstream from the carburetor at a special adaptor. The supplemental air inlet valve is specially constructed to utilize frictional forces arising out of air flow past the valve head, Venturi effect as the head nears closure, and finally pressure sealing at complete closure of the valve, in an efficient but low-cost design. The supplemental air valve is operated at a temperature, and supplemental air is introduced in a way, that results in condensation on its inner walls of oil vapors drawn through the PCV valve so that the condensed oil entraps particles of foreign matter that find their way through the supplemental air valve.
