摘要： A lean combustion method is provided for a four-stroke reciprocating internal combustion engine having a cylinder, in which a combustion chamber is delimited by a cylinder head and a piston is movable in a reciprocating manner, the piston being able to vary the volume of the combustion chamber. A fuel can be introduced directly into the combustion chamber, and at least one gas exchange inlet valve and one gas exchange outlet valve are provided for a gas exchange. An intermediate compression can be set in the combustion chamber at a gas exchange top dead center and a main compression can be set at an ignition top dead center.

摘要： 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.

摘要： A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger.
