摘要： In a cylinder head for a multi-cylinder engine, which is manufactured by a casting process and which has two intake ports and two exhaust ports for each cylinder, the formation of a coolant conduit is facilitated. During the manufacture by casting, a coolant conduit is formed using a sand core so as to avoid the undersides of the intake ports. Further, a concave portion which opens to the under surface of the cylinder head is provided underneath a pair of the intake ports. And a connecting hole is formed in the cylinder head by a mechanical process so as to communicate the coolant conduit with the concave portion. In the case of a prior art type engine in which a fuel injector or the like is provided under the intake ports and the portion of the coolant conduit which passes under the intake ports is formed by using a sand core, , the sand core for this portion is easily damaged from the constructional point of view. However, according to the above described construction, it is possible to provide a coolant conduit which passes underneath the intake ports without using any sand core for the formation thereof.
摘要翻译：在通过铸造工艺制造并且具有用于每个气缸的两个进气口和两个排气口的多缸发动机的气缸盖中，容易形成冷却剂管道。在通过铸造制造期间，使用砂芯形成冷却剂导管，以避免进气口的下侧。此外，在气缸盖的下表面开口的凹部设置在一对进气口的下方。并且通过机械过程在气缸盖中形成连接孔，以使冷却剂管道与凹部连通。在现有技术的发动机的情况下，在进气口下方设置燃料喷射器等，通过使用砂芯形成在进气口下方通过的冷却剂管道的部分，为此，部分从结构角度很容易损坏。然而，根据上述结构，可以提供通过进气口下方的冷却剂管道，而不使用任何用于形成砂芯的砂芯。

摘要： A schedule which is logged in terms of engine speed and which is divided into a number of engine operational zones, is used to determine the amount of axial displacement should be induced in a cam shaft on which a specially shaped cam is mounted. The cam has a first section which configured to simultaneously induce a change in valve lift and the valve closure timing, and a second section which maintains the valve closure timing at essentially a fixed value and induces a further increase in valve lift.

摘要： Main and sub-rocker arms mounted on a common shaft and pivotally supported on a cylinder head by a pivot formed at the end of an adjust screw which is provided at one of the main rocker arm. The main and sub-rocker arms are motivated by cams suited for low engine speed and high engine speed operation respectively. A hydraulically operated interlocking device which selectively locks the main and sub-rocker arms together, is controlled by a supply of hydraulic fluid by way of a passage structure formed in the adjust screw and a pivot seat in which the pivot is received.

摘要： The first of a pair scissor like rocker arms is pivotally mounted at one end either by way of an adjust screw or a hydraulic lash adjuster and arangement to engage the top of a valve stem at the other. A cam follower which is located between the first and second ends engages a lift cam. The second of the rocker arms is pivotally mounted on the first one and has a closure cam follower at one end and engages the lower face of a retainer which secured to the top of the valve stem by way of a ring type collet. The shaft on which the second rocker arm is pivotally mounted can be provided with eccentric portions which enable the second rocker arm valve clearances to be adjusted separately from the adjustment of the first rocker arm clearance. The arrangement can be adapted to lift and close two valves.

摘要： In a prior-art variable venturi carburetor in which the cross-sectional area of venturi is automatically varied according to the amount of intake air to keep the flow rate of intake air or the vacuum generated at the venturi at a constant level, since the cross section of venturi changes rectangularly, fuel is concentratedly jetted only near the middle portion of the venturi, so that fuel is not uniformly mixed with air passing through the venturi. To overcome these drawbacks, a wall having a reverse trapezoidal recess is provided near the nozzle and further a pair of triangular slots or cutouts are formed near the lower end surface of the suction piston obliquely and symmetrically so as to slidably engage with the wall, with the result that the cross section of the venturi changes trapezoidally and therefore a stable mixture is obtained even when the engine is running at a low speed or being idled.
摘要翻译：在现有技术的可变文丘里化油器中，文丘里管的横截面积根据进气量而自动变化，以将进气的流量或文丘里管上产生的真空保持在恒定水平，因为十字文氏管的一部分长方形变化，燃料集中喷射在文丘里管的中部附近，使得燃料与通过文丘里管的空气不均匀混合。为了克服这些缺点，在喷嘴附近设置具有倒梯形凹部的壁，并且在抽吸活塞的下端面附近形成一对三角形槽或切口，倾斜和对称地形成为与壁壁可滑动地接合，即使在发动机以低速行驶或空转的情况下，文丘里管的横截面也能够梯形变化，因此得到稳定的混合物。

摘要： An internal combustion gasoline engine has an air intake assembly which injects air through the cylinder head into the cylinder to generate swirl (horizontal vortex) flow (as opposed to tumble (vertical vortex) flow) for stratified charge combustion, and to generate tumble flow for homogeneous charge combustion. The piston includes a cavity combustion chamber at the top surface of the piston, the cavity combustion chamber having an increasing cross sectional area as the top of the piston is approached.

摘要： In order to prevent the electrodes of the spark plug from becoming wetted with droplets of liquid fuel during low temperature and/or idling operation of the engine in a manner which deteriorates engine stability, the branches of a bifurcate intake passage which cooperates with a dual inlet valve arrangement are arranged to guide the unvaporized liquid fuel into the combustion chamber in a manner which obivates contact with the plug. In some embodiments a passage which is adapted to produce a swirl in the combustion chamber is arranged so that the fuel which passes therethrough (usually in the form of a film on the walls of branches) and which has a relatively large inertia as compared with the gaseous charge, enters the combustion chamber with a velocity which carries it along a flight path non-intersective with the plug electrodes. In another arrangement, the swirl generating passage is arranged to branch off from the side of the other one which is essentially coaxially aligned with the passage of the induction manifold. With this arrangement most of the liquid fuel tends to pass into the essentially coaxially aligned one under the influence of its own inertia and thus reduces the amount of liquid fuel entering the swirl generating one.
