Abstract

A number of embodiments of these valve intake systems for internal combustion engines served by a siamese type intake passage and configured to generate a swirl in the intake charge. A single fuel injector sprays fuel into a common inlet opening of the siamese intake passage and sprays more fuel toward the swirl side port so as to insure equal flow through all of the ports.
