Abstract

PURPOSE:To produce the swirl optimum for the operational conditions of an engine constantly and automatically assuring low fuel consumption and producing less waste gas by a method wherein a tongue of suction port swirling part producing swirl is formed of a shape memorizing metal and the tongue is controlled by a thermostat corresponding to revolution and load of the engine. CONSTITUTION:A tongue 3 of a swirling part 2 of a suction port 1 is formed of a shape memorizing metal changing its shape corresponding to the change of temperature. Any signals from the revolution and load detector of an engine are transmitted to a computer to control the values of a resistor buried in the tongue 3 as well as the temperature of the tongue 3 corresponding to revolution and load of the engine so that the projection of the tongue 3 may be changed to produce the optimum swirl ratio for revolution and load of the engine.

　　　　−以下本発明の実施例を図面に基いて説明する
。This swirl ratio is controlled by a tank formed in the swirl portion of the intake port, and the present invention improves this tank and eliminates the above-mentioned conventional problems.
- Hereinafter, embodiments of the present invention will be described based on the drawings.

第１図及び第２図において、１は吸気ポート、２は渦巻
