摘要： A spark ignition fuel injection reciprocatory internal combustion engine with dual induction system is provided which has within a cylinder head a primary intake port passage to direct air charge into a cylinder to swirl therein and a secondary intake port passage to direct air charge into the cylinder in such a direction as to impede and reduce the swirling motion of the air charge issuing from the primary intake port passage. An intake valve, including a valve stem and a valve head, is reciprocably mounted within the cylinder head, and an annular wall or tube is fixedly positioned in a bore in the cylinder head. The primary intake port passage communicates with the exterior of this tube and the secondary intake port passage communicates with the interior of the tube. This tube extends to a position closely adjacent to, or in engagement with, the valve head of the intake valve when the valve is in the closed position. A fuel injector, mounted to the cylinder head, discharges fuel into the secondary intake port passage toward the central portion of the head and synchronization with the opening of the intake valve so that the fuel issuing from the fuel injector will impinge upon the valve head and then disperse radially outwardly toward the periphery of the valve head. An air flow sensor is provided upstream of primary and secondary throttle valves to detect the total of flow of induction air fed to the engine so that fuel is discharged at a rate proportional to the total induction air flow.

摘要： An induction system for a multi-cylinder internal combustion engine that improves fuel efficiency and reduces the emission of unwanted exhaust gas constituents, particularly at the low and medium load conditions. The engine induction system comprises a plurality of separate carburetor barrels which, at least under some running conditions, serve cylinders separately from each other through main induction passages. One carburetor barrel is provided with a different fuel discharge system than the other carburetor barrels for accomodating a certain engine operating condition. A separate sub-intake system connects this carburetor barrel with other cylinders not normally served by the particular carburetor barrel in question. This sub-intake system has a substantially smaller cross-sectional area in the main intake system so that the charge drawn into the cylinders through the sub-intake system enters at a substantially higher velocity. This improves combustion by creating turbulence under at least some operating conditions. The ratio of flow between the sub-intake system and the main intake system is controlled by a series of throttle valves. In accordance with this invention constructions are provided for delaying the movement of the throttle valve associated with the other carburetor barrels from that associated with the one carburetor barrel for improving the transitional performance of the engine. In certain embodiments of the invention this delay in movement is accomplished by a resilient connection in the throttle linkage.

摘要： A multi-cylinder internal combustion engine having a plurality of cylinders, each comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chambers are interconnected to each other via a common connecting passage. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle.

摘要： In an internal combustion engine, an injection hole is provided in the cylinder head to inject narrow streams of air towards the spark gap, particularly during idling and low load running conditions. The injected air is 5 to 30% by weight of the intake fuel-air mixture provided via the intake manifold and creates a swirl or turbulence thereby increasing combustibility. The hole is connected via a sub intake passage to the main air intake passage upstream of the venturi in the carburetor or between the venturi and throttle valve.

摘要： An intake device of an internal combustion engine includes a partition, a gap, and a projecting part. The partition divides an interior of an intake pipe into a first passage and a second passage. The gap exists at a boundary between an inner face of the intake pipe and the partition or in the partition, and couples the first passage and the second passage. The projecting part is disposed near the gap on a face of the partition or the inner face of the intake pipe that forms an inner face of the first passage, or on a face of the partition or the inner face of the intake pipe that forms an inner face of the second passage.

摘要： Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, in response to flowing the exhaust gas recirculation and blowthrough air from the first exhaust manifold to the intake passage via a first set of exhaust valves, a first set of swirl valves coupled upstream of a first set of intake valves may be adjusted to at least partially block intake air flow to the first set of intake valves. Each engine cylinder may include two intake valves including one of the first set of intake valves and two exhaust valves.
