Abstract: A device is proposed for the supply of operating air-fuel mixtures including exhaust gases to internal combustion engines. Between the opening periods of the inlet valves of an internal combustion engine, precisely dispensed quantities of recirculated exhaust gas are pre-stored in the intake channel directly upstream of the inlet valve whereby a stratification of exhaust gas and fuel-air mixture in the combustion chamber of the engine is obtained.

Abstract: In a diesel engine having a turbocharger for feeding supercharged air to the engine, an exhaust gas recirculation passage communicates between the exhaust passage from the engine and the intake passage to a compressor of the turbocharger. A first control valve closes the exhaust gas recirculation passage when the output pressure of the air leading from the compressor is lower than a first predetermined value or higher than a second predetermined value which is higher than the first predetermined value. A second control valve may be further provided within the exhaust gas recirculation passage so as to close the exhaust gas recirculation passage when the load applied to the engine is above a predetermined value.

Abstract: An exhaust gas recirculation system comprises a valve assembly for controlling the recirculation of exhaust gases in such a manner as to maintain a difference between a first and second pressure at a predetermined value. The first pressure is a pressure in a zone in an air induction passage between a throttle valve therein and a flow restrictor disposed therein downstream of the throttle valve, while the second pressure is a pressure in a zone in an exhaust gas recirculation passage between an exhaust gas recirculation flow control valve member and a second flow restrictor disposed therein downstream of the valve member.

Abstract: A modification to or ancillary apparatus for carburetors for internal combustion engines to prepare liquid fuel for internal combustion engines by supplying supplementary air such as air or exhaust gas into the induction system downstream of the butterfly valve of the carburetor having at least one slit for discharging into the induction system supplementary air dependent upon a control member and its relation to the butterfly valve position. In one embodiment air enters through one slit at all times during engine operation to primarily improve idling mixture while air is supplied to the second slit in quantities dependent upon the butterfly valve position. In a second embodiment the air is supplied by way of one or more slits in quantities determined by the butterfly valve setting but without the continuous air supply independent of that butterfly valve position for idling mixture. In either embodiment the air enters the slits at very high speed and that speed approaches the speed of sound when the engine is idling for the one slit in the first embodiment and in part-load ranges of the engine for the other slits in either embodiment.

Abstract: An exhaust gas recirculation system whereby a part of exhaust gas is recirculated to the downstream of the carburetor throttle valve through an exhaust recirculation passage for removing the nitrogen oxides in exhaust gas discharged from an internal combustion engine, wherein a pressure control valve is provided in the after-flow of the flow control valve which controls the rate of exhaust gas recirculated to the downstream of the throttle valve disposed halfway in said exhaust recirculation passage, said pressure control valve being arranged such that its opening will be reduced when negative pressure in the downstream of the throttle valve is high and that said opening will be enlarged when said negative pressure is low, whereby the amount of exhaust gas taken into the engine is made basically proportional to the air intake so that the recirculation ratio will be maintained substantially constant over a wide range of operation.

Abstract: The plenum of an independent runner manifold is oriented at an angle to the longitudinal center line of the manifold such that each carburetor throat of a four barrel carburetor sees the entire entrance of two adjacent runners of different runner pairs. Each of four runner pairs has two runners leading from the plenum to side-by-side inlet ports. The wall lengths within a runner are made at least nearly equal to each other. A sudden enlargement, in the form of a step, is provided proximate the entrance of each runner of a manifold to the ports of an engine along the outer wall thereof where mixture velocity is relatively low with respect to mixture velocity elsewhere in the same velocity profile. The enlargements control reverse mixture flow and increase the amount of mixture entering the engine's cylinders. It is believed that this increase in flow is partially due to a reduction or elimination of boundary layer separation in the inlet port. The geometry of the runners is such as to promote relatively high mixture velocity. Specifically, the cross-sectional area of each runner progressively diminishes downstream from the entrance to the runner at the manifold's plenum.

Abstract: The manifold and cylinder head structures of an internal combustion engine are provided with fluid flow passageways extending from the manifold plenum to the valve ports of the engine cylinders, with fluid flow control members disposed in the passageways and defining peripheral restrictions therein. In some modifications the members are integrally formed in a gasket sandwiched between the manifold and the cylinder head and having openings registered with the passageways, which openings have a cross sectional area less than the passageway cross sectional areas. In some modifications the insert members are elongated and increase in cross sectional area from the upstream to the downstream ends. In some modifications, each insert member has an integral flange at either end or intermediate the ends, the flange being retained between the manifold and the cylinder head. In some modifications a plurality of members are formed integrally in a single gasket element sandwiched between the manifold and the cylinder head. In some modifications, the insert members are integral with the manifold or with the cylinder head port runners. In some modifications, the intake passageway insert members are press fit or otherwise secured closely adjacent the intake ports.
