  • Patent number: 10041440
    Abstract: An insert for a cylinder head of an internal combustion engine that has a bore for receiving a fuel injector to deliver fuel through an injector nozzle into a combustion chamber. The insert comprises a generally tubular body having a longitudinally oriented passageway therethrough and receivable within the bore in the cylinder head. The generally tubular body has an inner end and an outer end, with the inner end in proximity to the combustion chamber when said insert is received within the bore. The passageway is tapered such that its diameter increases from the inner end toward the outer end. The longitudinal passageway is dimensioned to sealingly receive the nozzle of the fuel injector when the fuel injector is received within the bore. The insert limits blow-by between the insert and the nozzle of the fuel injector during operation of the internal combustion engine.

  • Patent number: 10030572
    Abstract: A coolant circuit is provided for an internal combustion engine having a compression machine for intake air. The coolant circuit includes a high-temperature circuit and a low temperature circuit. The high-temperature circuit is provided in order to cool the internal combustion engine by way of a coolant radiator and a first coolant pump arranged in the high-temperature circuit. The low-temperature circuit is provided with a second coolant pump in order to cool the intake air compressed by the compression machine by way of an intercooler and in order to cool a coolant of a coolant circuit in a condenser. The high-temperature circuit and the low-temperature circuit are cooling circuits which are separated from each other. The thermal base load of the low-temperature circuit is reduced by this design, whereby the pressure level in the coolant circuit can be reduced resulting positively in a reduction of the energy consumption.
