Effect of temperature on valve seats when operating on alternative fuels

Popis výsledku v původním jazyce

The head of SI engine, in which are pressed intake and exhaust seat valves is one of the most complex part of the SI engine. There are stored in it intake and exhaust ports, spark plug, the timing mechanism and channels for cooling and lubrication. Much of the final form of this component also contributes its load, which is both thermal and mechanical. The biggest influence on deformation inserted seat valves has a temperature distribution in the cylinder head. These temperatures are influenced by many factors, including temperature and coolant flow, load and engine speed, which affect the combustion process and exhaust gas temperature (these factors in normal mode, the engine is constantly changing, therefore the thermal load valve seat is different). The paper describes the temperature measurement in hard to reach places in the cylinder head of the engine when operating on alternative fuel - namely butanol and a mixture of gasoline and compares the temperature on the valve seats when operating on alternative fuel and gasoline.
