Zonal cooling principle model engine. Experimental results

This paper provides a detailed analysis of the tests performed with spark ignition engine zonal cooling. Zonal cooling principle assumes two circuits, one for cylinder head and block continuous adjustment temperature in accordance working principle. In order to test proposed solution, it was necessary create functional model thermal regime, an aspect that led redesign some subassemblies parts reach desired requirements. this sense, criteria related adaptability these solutions on structure current engines were considered, first, but also those technological facilities, reliability, simplicity, low cost. The above considerations use experiments, car architecture construction. Thus, is based engine, powered by single point injection system. An capacity 1600 [cm3] relatively common equipment variants, which reason choosing type engine.
