摘要： To enable a reduction of the number of fuel pipes and joint parts to facilitate piping work, maintenance and inspection. An engine fuel injection apparatus includes first fuel injection valves provided on an upstream side of an air intake passage of an engine, second fuel injection valves provided on a downstream side of the air intake passage, and a fuel pump for supplying fuel to the first and the second fuel injection valves. The second fuel injection valves are positioned at a level lower than the first fuel injection valves, and the fuel pump is connected to the second fuel injection valves via the first fuel injection valves by fuel feed pipes, so that fuel does not return to a fuel tank of the engine.

摘要： Axis lines of first and second fuel injection valves are offset from first and second cylinder center lines of first and second combustion chambers by way of moving the first and second fuel injection valves along cam shafts by constituting limits by bringing fuel injection ranges of the first and second fuel injection valves to inner walls of opening portions. Even when the positions of the intake manifolds are obliged to move along the cam shafts, fuel injected from the fuel injection valves can be made to be difficult to adhere to the inner walls of the opening portions and vaporization of fuel can be expedited. Therefore, a mixture in the combustion chambers can be made uniform and engine performance such as response performance of engine rotation, fuel consumption, exhaust gas properties, occurrence of knocking or the like when the throttle valve is opened, can be improved.

摘要： To provide a mechanism for coordinating the operation of throttle valves in a carburetor system in which a plurality of carburetors are connected in series and are then arranged in parallel with one another so as to position shafts thereof in parallel with one another. The throttle valves are rotated on said shafts to open or close passages of the carburetors. In the throttle valve operation coordinating mechanism, each of the carburetors connected in series shares one shaft which is received in bearings positioned at opposite ends thereof. A link extends between the shafts of the carburetors arranged in parallel and coordinates the operation of the shafts.

摘要： A bypass passage includes an inlet in communication with the upstream sides of first and second throttle valves of first and second suction passages. One valve body receiving chamber is coaxial with the inlet. First and second upstream side branch passages extend from the valve body receiving chamber. Downstream side branch passages extend from the end portions of the upstream side branch passages and are in communication with the downstream sides of the first and second throttle valves of the first and second suction passages. One bypass valve is movably received in the valve body receiving chamber and can open the first and second upstream side branch passages to be at the same opening. Reducing the number of bypass valves to one can reduce the manufacturing costs and the number of man hours for assembly of the throttle unit and can equalize the rate of air flowing through the respective bypass passages.

摘要： To provide a multi-cylinder engine in which a plurality of cylinder bore rows, each including a plurality of cylinder bores disposed in parallel, are disposed in such a manner as to be perpendicular to a crank shaft disposed substantially in the horizontal direction. A plurality of cylinder heads, each forming combustion chambers between pistons slidably fitted in the cylinder bores and the cylinder head, are connected to cylinder blocks corresponding to the cylinder bore rows. Furthermore, a plurality of intake passages and a plurality of exhaust passages respectively in communication with the combustion chambers are provided in the cylinder heads, wherein the structure of an intake system and an exhaust system can be simplified. Intake passages and exhaust passages are provided in the a cylinder head corresponding to a cylinder bore row in such a manner that a relative positional relationship between the intake passages and the exhaust passages in the axial direction of the crank shaft is nearly equal to that between the intake passages and the exhaust passages in the axial direction of the crank shaft.
