Abstract: An exhaust gas line system for an internal combustion engine supercharged by an exhaust gas turbocharger, having a modularly assembled exhaust gas collector pipe (1), which supplies the turbocharger with exhaust gas and is connected to all cylinders of a bank of cylinders via connecting lines (2), the exhaust gas collector pipe (1) being closed at its end distant from the turbine and exhibiting, over its entire length, a nearly constant cross section. It is the object of the invention to create, for a supercharged internal combustion engine, an exhaust gas line system that utilizes the kinetic energy of the exhaust gas in the most loss-free possible fashion for driving the turbocharger. This is achieved by the connecting lines (2) discharging into the exhaust gas collector pipe (1) via a diffusor-shaped inlet opening (3) and by providing a constriction (4) upstream of the inlet opening.

Abstract: A braking device for a four-cycle engine of a vehicle, particularly for an internal combustion Diesel engine, with a motor brake adjustment member which is connected with a shutoff element in the exhaust conduit and with a control element in a pressure conduit. Pressure cylinders are associated with the exhaust valves and are connected to the pressure conduit after the control element. Compensating pistons are respectively connected with the valve shafts and are subjected to pressure in the pressure cylinders for closing the exhaust valves. The motor brake adjustment member has a first adjustment range for actuating the shutoff element, and a second adjustment range for actuating the control element.

Abstract: 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.

Abstract: 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.
