LADELUFT-WAERMETAUSCHERANLAGE

摘要

A heat-exchanger system for the charging-air of a low-compression reciprocating piston internal combustion engine operating with exhaust gas turbo-supercharging, which is equipped with a first charging-air-water heat-exchanger that during the starting and partial load operation supplies the heat energy of a heater device to the charging air and which can be connected to the cooling water circulation of the internal combustion engine, and with a second charging-air-water heat-exchanger which is connected to the cooling water circulation external to the engine; the two charging-air-water heat-exchangers are thereby adapted to be traversed in parallel by the charging-air while a control system enables a stepless control of the charging air flow through the individual heat-exchangers as a function of the temperature of the charging air upstream of the cylinders and of the operating condition of the internal combustion engine.
