    Pracovní cyklus dvoudobého spalovacího motoru s modifikovaným vratným vyplachováním

  • Annotation in Czech

    Cílem je návrh základních konstrukčních parametrů nového dvoudobého zážehového motoru s modifikovaným pracovním cyklem, který eliminuje nevýhody dosavadního standardního provedení. Cílem je tedy návrh a ověření funkce motoru s dvoudobým pracovním cyklem, který bude vhodný jak pro stacionární, tak i pro mobilní použití (výstupem projektu jsou dva prototypy).

    The engine's ability to work with gaseous fuels was confirmed, which was the basic goal of the project. The method of gas ignition was verified in a prototype. Spark plug ignition was applied. The ignition chamber, developed in cooperation with the Czech Technical University, will enable the application of the developed engine design even for larger displacement and reduction of emissions due to the use of higher energy of the ignition element. 3-D simulations confirmed the assumption of the engine's ability to run at lower speeds. This feature will be suitable for use with smaller stable units (cogeneration units, electricity generators), which are the main anticipated area of future use.
