Abstract
A six cylinder internal combustion engine having first and second groups of three adjacent combustion chambers and an exhaust valve port connected to each of the six combustion chambers. In each group of three adjacent combustion chambers the exhaust valve ports of the side combustion chambers are positioned on the side of the middle combustion chamber thereby reducing the length and surface area of the exhaust passages and maintaining a high exhaust temperature. First and second confluence members join the exhaust valve ports of the first and second groups of three adjacent combustion chambers respectively to an exhaust reaction chamber. The ignition timing of the combustion chambers is controlled in order that the periods of successive exhaust valve port openings partially overlap. This allows the cooler gases at the end of the exhaust stroke to be heated by the hot gases produced at the ignition of the next successive combustion chamber exhaust stroke which further maintains a high exhaust temperature in the exhaust reaction chamber.
