    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.

    摘要： A variable valve timing type rocker arm arrangement is arranged so that, in the absence of sufficient hydraulic pressure to operate the interlocking mechanisms which switch the valve lift control from one cam follower to another, it defaults to a cam follower suited for low speed engine operation rather than one which is adapted to maximize fuel economy. During engine starts (when oil pump output is inherently low) the initial low speed cam follower defaulting improves aspiration and reduces the tendency for incomplete combustion to induce the formation of smoldering deposits on the spark plug electrodes. In the event of an actual hydraulic system malfunction, the defaulting enable the engine to produce enough torque to render the vehicle drivable.

    摘要： An engine valve operating system for an internal combustion engine comprises a rocker arm for transferring valve actuating effect from a driving cam to an engine valve such as an intake or exhaust valve. An elongate lever or fulcrum member is pivoted at its one end section and disposed in fulcrum contact with the side of the rocker arm opposite to the driving cam. Additionally, a hydraulic actuator is provided to control the pivotal location of the lever and therefore has a movable end section which is in contact with the other end section of the lever and movable in accordance with an engine operating condition, thereby greatly improving control response of the lever while rendering unnecessary a large capacity and sized actuator.

    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.
