摘要： A multicylinder engine exhaust manifold system comprises a first manifold (16) having branches leading from individual exhaust ports (14) of the engine to a downpipe, and a second manifold for interconnecting the exhaust ports. The second manifold is constructed in the form of a block (20) having individual through passages (28) communicating the engine exhaust ports (14) with the branches of the first manifold (16) and a transverse passage (24) passing through and interconnecting the individual passages (28). The transverse passage (24) has housed in it a thin-walled conduit (32). The conduit (32) partially obstructs the individual passages (28) and has openings facing the engine exhaust ports (14). The conduit (32) is in poor thermal contact with the block (20) and having a low thermal capacity relative to the block (20), in order to minimise cooling of gases transferred between exhaust ports (14).

摘要： A method is described for varying the engine load while maintaining optimum charge stratification in a stratified charge engine. In the invention, at least under low and part load conditions, the intake streams (22, 32) supplying the stratified charge are throttled (50, 60) in proportion to one another so as to vary the charge density uniformly across the entire combustible charge without significantly varying the relative volumes of the separate streams nor their relative velocities as they are drawn into the combustion chamber, the relative velocities being such as to minimise mixing within the combustion chamber between the intake streams during the intake and compression periods of the engine.

摘要： An intake system is described for a spark ignition internal combustion engine having ports per cylinder, which may lead to a common intake valve or two separate intake valves. One of the intake ports (12) is shaped to direct a first flow tangentially near the outer periphery of the cylinder and the other intake port (20) is shaped to direct a second, swirling, flow towards the centre of the cylinder. The second swirling flow has the same direction of rotation as that of the first flow. Injectors (28) are provided for introducing fuel into the second swirling flow thereby producing within the cylinder a charge that is radially stratified with a combustible mixture concentrated near the centre of the cylinder. The flow rates through the two intake ports may be varied independently and the relative angular momentum of the two flows at the boundary between the two flows in the cylinder determines the degree of mixing between the two flows, such mixing being operative to decrease the degree of stratification of the charge within the cylinder.

摘要： A multicylinder engine exhaust manifold system comprises a first manifold (24) having branches (22) leading from individual exhaust ports (20) of the engine to a downpipe (26), and a second manifold (34) for interconnecting the exhaust ports (20) and also having branches (32) leading to the individual exhaust ports (20) of the engine. The cross-sectional area of each branch (32) of the second manifold (34) facing the exhaust flow from the associated exhaust valve is no less than 25 % of the total port area and the branches of both manifolds (24, 34) terminate within the ports (20) in close proximity to the exhaust valves (18). In this way, a large proportion of the exhaust flow discharged from the exhaust valve of one cylinder is captured by the associated branch (32) of the second manifold (34) and distributed by the second manifold (34) to the exhaust ports (20) of adjacent cylinders where the exhaust valves (18) are closed and leave the exhaust ports (20) of the adjacent cylinders through the associated branches (22) of the first manifold (24), scouring the closed ends of the exhaust ports (20) in the process.

摘要： An intake manifold system (10) is described for a multi-cylinder four stroke spark-ignition internal combustion engine (12). Each cylinder has at least one intake port (20), each intake port (20) being connected at one end to the combustion chamber by at least one intake valve (14) and at the other end to a first intake duct (22) that is connected to a first plenum (24) common to the first intake ducts (22) of other engine cylinders. Each intake port (20) is also supplied by a second intake duct (32) the through-flow cross section of which is 25% to 45% of the maximum effective through-flow cross section of the open intake valve. The geometry of the intake port (20) and of the discharge end of the second intake duct (32) is such that the gas that enters from one side of the intake port (20), is constrained by solid boundary walls to perform a single U-turn by flowing around the intake valve stem (14) while adhering to the walls of the intake port (20) and enters the first intake duct (22) via the other side of the intake port (20), the gas thereby scavenging the closed end of the intake port (20) and displacing substantially all the gases previously present therein into the first intake duct (22).

摘要： A drive mechanism is described for transmitting driving torque from the crankshaft to a camshaft of an internal combustion engine. The mechanism incorporates means for permitting a limited degree of rotation of one of the shafts relative to the other and comprises concentric drive and driven members (14, 10) connected respectively to the crankshaft and the camshaft. At least one lever (20) is pivotably supported on one of the members (10) and has a force transmitting surface that is biassed by a spring (22) to remain in contact at all times with a reaction surface (24) on the other member. The position of the point of contact between the two surfaces is dependent upon the relative angular position of the drive and driven members (14, 10) and moves progressively to vary the mechanical advantage of the lever as the shafts rotate relative to one another under the action of the torque reversals on the camshaft (12).
