摘要： An air intake device of an engine has intake pipes connected to each of the engine cylinders divided into first and second groups to prevent the continuance of the intake strokes of adjacent cylinders. A first connecting cavity connected to the first group of cylinders and a second connecting cavity connected to the second group of cylinders are arranged in parallel with each other, for effecting supercharging by utilizing the dynamic effect of intake air into each cylinder. A first communicating passage is connected at one end to a longitudinal end of the first connecting cavity and at the other end to a longitudinal end of the second connecting cavity. A second communicating passage arranged on the same side as the first communicating passage is connected at one end to a side of the first connecting cavity and at the other end to a side of the second collecting cavity. The effective passage length of the first communicating passage is shorter than that of the second communicating passage.

摘要： Cylinder head construction defining a hemispheric combustion chamber and including a guide wall facing an intake port to impart swirl to an incoming air-fuel mixture and permit use of a lean air-fuel mixture. The position of the guide wall relative to the cylinder center and relative disposition of the guide wall and a spark plug are made such that although the guide wall is effective in imparting swirl, a flame front may be efficiently propagated to all parts of the combustion chamber subsequent to ignition of the air-fuel mixture therein, whereby provision of the guide wall does not result in increased emission of hydrocarbon compounds in exhaust gas or formation of carbon deposits in the combustion chamber.

摘要： Internal combustion engine having a primary and a secondary intake passage for each cylinder, the passages opening to the combustion chamber through a common intake port having an intake valve. A substantially radially extending partition plate is disposed at the intake port so as to separate the two passages one from the other when the intake valve is closed.
