METHOD AND DEVICE FOR INCREASING THE EFFICIENCY OF TWEETACT ENGINES.

摘要

The flow of exhaust from an engine is impeded by the friction caused by carbon deposits. To keep the flow resistance constant a flap valve with adjustable resistance is used. The flap valve (4) is mounted by means of a clip (2) on the end of the exhaust pipe. The hinge point (3) of the flap is outside the pipe diameter. A counterweight (5) is mounted on the flap, by means of which the force required to open the flap can be adjusted. A few holes are drilled in the flap, so that some gas can escape when the flap is fully closed.
