A pipe connection for conducting a fluid that is under pressure is provided, having two tubular connection parts for a conical clamping connection, which are screwed together by a union nut while one is inserted in the other, wherein each connection part has a conical sealing surface that contacts the other in a sealing manner and wherein an annular groove is provided in one of the sealing surfaces. In order to enable the pipe connection also to conduct a fluid having cycling or varying temperature, the inner of the two connection parts has thermal insulation on the inside of the pipe at least in the axial segment of the sealing surface of the connection part, wherein the thermal insulation tube has a cam or a collar on the outer surface, which engages in a recess, which is axially bounded by the two connection parts.

Pipe connection for conducting a fluid that is under pressure

A reciprocating engine includes a combustion chamber, and a gas exchange inlet valve and a gas exchange outlet valve for a charge cycle. The method introduces an inlet gas into the combustion chamber in an intake phase; introduces a primary quantity of fuel into the combustion chamber during the intake phase and/or a compression phase; compresses the inlet gas and the fuel in the compression phase; ignites a mixture of inlet gas and fuel formed in the combustion chamber; and expands and discharges an exhaust gas formed by the combustion in an expansion phase. A pilot quantity of fuel is introduced into the combustion chamber before the primary quantity of fuel is introduced. Intermediate products of the pilot quantity of fuel are formed and the primary quantity of fuel is introduced into the combustion chamber during the compression phase such that complete ignition of the mixture consisting of inlet gas and the intermediate products is suppressed and other intermediate products are formed until a controlled ignition of the mixture and other intermediate products occurs.
