An internal combustion engine and a method of operating the same, which engine includes a supercharger having an exhaust gas turbine and a charging air compressor with a charging air line supplying charging air to the internal combustion engine. A bypass line is provided for connecting the charging air line with the exhaust gas line and a combustion chamber is disposed in one of the exhaust gas line and the bypass line. A return line for recycling exhaust gases branches off from the line in which the combustion chamber is disposed and a connecting line is provided for connecting the exhaust gas line with the charging air line. Arrangements are provided for at least one of selectively restricting and blocking at least one of the charging air line, bypass line, exhaust gas line and return line.

Supercharged internal combustion engine and method of operation thereof

An air filtering installation for an internal combustion engine equipped with a supercharger and a supercharger inter-cooler, in which the air filtering installation includes a centrifugal dust separator and a dry air filter with interchangeable filter insert; the centrifugal dust separator is thereby arranged on the suction side of the supercharger and the dry air filter is arranged downstream of the supercharger inter-cooler.

Air filter installation

A multi-cylinder diesel internal combustion engine with a supercharger and a charging air starting arrangement which includes a starting air reservoir and a starting air distributor. An additional air reservoir is provided for storing a quantity of supplemental charging air with the additional air reservoir being selectively communicated with air inlet valves during at least an acceleration and/or sudden loading of the engine.

Diesel internal combustion engine

A cooling device for liquid-cooled internal combustion engines, which device includes an annular radiator core or block which is traversed by the cooling air from the inside thereof toward the outside thereof, with a radial-flow fan or blower equipped with a rotor being arranged on the inside of the annular radiator core or block for axially sucking in the cooling air through an opening provided in a vehicle housing. A second annular radiator core or block for cooling the fuel for the internal combustion engine is disposed concentrically within the first-mentioned annular radiator core or block at a position downstream of the rotor, as viewed in the intake direction of the cooling air. The rotor of the radial-flow fan or blower is constructed such that a communication is provided between each vaned duct of the rotor and an annular rotor side chamber disposed within the second annular radiator core or block to effect a stream of cooling air through the second annular radiator core or block.

Cooling device for an internal combustion engine

A method and apparatus for operating an internal combustion engine equipped with an exhaust gas turbo-supercharger and with a combustion chamber which supplies additional gas to the exhaust gas turbine; during idling of the internal combustion engine, the combustion chamber is operated at such partial output that with lowest possible fuel consumption of the combustion chamber, an increased starting-supercharged air-pressure, as necessary for as favorable a load acceptance behavior as possible, will establish itself in the supercharged air lines whereas during the acceleration of the internal combustion engine, the output of the combustion chamber is increased for a rapid increase of the supercharged air pressure in the supercharged air line in order to attain a spontaneous load acceptance behavior of the internal combustion engine; during a further increase of the supercharged air pressure in the supercharged air line, initiated by the increasing exhaust gas supply with an increasing internal combustion engine output, the output of the combustion chamber is then again correspondingly reduced.
