The intercooling of charge air is one way of possible arrangements done while preparing fuel for diesel engines with the objective of lowering the environmental load. Such intercooling has other positive effects, e.g. the output increase, decrease in the maximal temperature of engine working cycle, decrease in thermal load of functional parts in the combustion space. Coolers of different constructions and versions are used for the charge air intercooling. As we have already presented in conferences and professional journals, we have been engaged in basic research into the non-conventional energetic system with the cooling combustion engine (the engine cooling circle is the ejector of absorption cooling). The obtained cold can be used for different purposes, e.g. for air conditioning of the maintenance room, cooling of goods storage space in trucks and also for more intensive intercooling of the charge air. Simultaneously with the mentioned topics we have been partially dealing with the influence of more intensive intercooling on the engine ecological parameters. We have presented some results of mathematical modelling connected with the mentioned topic. The paper is a continuation of previous publications and focuses on results of the experiment observing a two-stage charge air intercooling to lower temperatures. The air-to-air cooler was used as the first intercooling stage while the second stage was performed by means of the water-air intercooler.
