Abstract

The eight cylinder V-type IC engine has an air intake system which has two intake chambers (4) mounted parallel to each other on opposite sides of the longitudinal centre-line (L) of the engine. Each intake chamber (4) is connected by four ducts (2) to the inlets of the cylinders on the opposite side of the engine. The cross-sectional area of each intake chamber decreases at a uniform rate in the direction in which the air flows through the chamber in the direction (F) so that the cross-sectional area corresponds to the number of cylinders to be supplied with air. USE - Inlet manifold for V-8 engine.

Die Saugrohranlage 1 ist symmetrisch zu einer senkrechten, eine nicht gezeigte Kurbelwelle aufnehmenden Längsebene L und die V-Form überdeckend angeordnet. Zu jedem Zylinder des Motors führen einzelne Saugrohre 2, die in einer horizontalen, senkrecht zur Längsebene L verlaufenden Querebene Q enden und dort an Einlaßkanäle angeschlossen sind. An intake manifold system 1 , which is identical to the direction of travel of the motor vehicle, is arranged in a longitudinal direction F on an 8-cylinder V-motor for a motor vehicle, not shown. The intake manifold system 1 is arranged symmetrically to a vertical longitudinal plane L which receives a crankshaft (not shown) and covers the V-shape. Each intake manifold 2 leads to each cylinder of the engine, which ends in a horizontal transverse plane Q running perpendicular to the longitudinal plane L and is connected there to inlet ducts.
