Embodiment Construction

[0033] figure 1A prior art internal combustion engine 10 is discussed comprising: a cylinder block having at least one cylinder and at least one cylinder head, and having at least one turbocharger 12 having a shaft 14, a turbine 16 and compressor 18 ; and an intercooler arrangement 20 between compressor 18 and engine 10 . Turbine 16 of turbocharger 12 communicates with an exhaust manifold 22 at a cylinder head of engine 10 , and compressor 18 communicates with a charge air receiver 24 at a cylinder head of engine 10 . The intercooler structure 20 includes two charge air coolers provided with heat exchange surfaces, namely a high temperature (HT) charge air cooler 26 with HT heat exchange surfaces and a low temperature (LT) intercooler with LT heat exchange surfaces. Compressed air cooler 28 , the charge air cooler is arranged such that charge air leaving compressor 18 is directed first into HT charge air cooler 26 and subsequently into LT charge air cooler 28 . The HT charge...

Abstract

The present invention relates to a turbocharged internal combustion engine provided with means for flushing dirt periodically from the heat exchange surfaces of the LT- charge air cooler by using water condensed on the heat exchange surfaces for the flushing.

Description

technical field [0001] The invention relates to a cleaning method of a charge air cooler of an internal combustion engine as discussed in the preamble of claim 1 and to an internal combustion engine as discussed in the preamble of claim 10 . Background technique [0002] Both economical and environmental aspects now lead users of internal combustion engines to require engines with the lowest possible specific fuel consumption. This need has led to the use of devices that increase the charge of air in the cylinders of the engine compared to normally aspirated engines. The first such device is usually called a supercharger and its main task is to increase the pressure or density of the air, that is, to compress the air entering the cylinders of the engine. There are two main types of superchargers. The first is a turbocharger, commonly called a turbine, which is a unit that has a turbine wheel and a compressor wheel on the same shaft so that the engine's exhaust gas drives t...
