A valve-controlled internal combustion engine has the amount of twist in the combustion air flowing through a curved inlet channel to a valve chamber controlled by a control rod extending across the bottom wall of the inlet channel near the valve chamber and rotatable from outside the engine to change the cross sectional dimensions of the inlet channel and increase or decrease the twist in the flow of combustion air therepast.

Internal combustion engine having rods for controlling twist pattern in

An internal combustion engine and a method of operation thereof in which a plurality of compressors are connected through check valves with the inlet means of the working chambers of the engine while the working chambers are connected through control valves and gas turbines, each of which drives a respective compressor. The control valves are arranged to open sequentially as engine speed increases and to close sequentially as engine speed decreases with the opening of each control valve taking place more rapidly and at a higher engine speed than the closing thereof. In starting the engine, only one of the turbine is supplied with gas to initiate a supply of compressed air for use in starting the engine.
