摘要： A method and apparatus for preventing an overheating of an exhaust gas purification block for internal combustion engines in case of a high proportion of combustible gas components in the exhaust gases, in which the exhaust gases are adapted to be conducted past the exhaust gas purification block by way of a controllable by-pass line; at least during the periods when the by-pass line is opened, air preferably in the form of an air jet directed opposite to the normal exhaust gas flow is blown into the line leading into the exhaust gas purification block whereby preferably the air jet passes over the inlet opening of the exhaust gas purification block in a transverse direction.

摘要： A mixture-compressing reciprocating-piston internal combustion engine with two separate cylinder rows and a single mixture-producing device, in which one row is supplied with a slightly richer air/fuel mixture from a common mixture-producing device which is then leaned down by the admixture of additional air while the other cylinder row is supplied with an air/fuel mixture which is as accurately as possible stoichiometric; oxygen probes are thereby used upstream of the respective catalysts to control a valve controlling the additional air inlet to the one cylinder row and the fuel supply to the mixture-producing device.

摘要： A method and apparatus for controlling a multi-cylinder internal combustion engine by connecting or disconnecting one or several of the cylinders with a throttling device provided in the suction system of the internal combustion engine; simultaneously with the connection or disconnection of the cylinder or cylinders, the position of the throttling device is so changed jump-like that the output of the internal combustion engine remains essentially unchanged.
