Абстракт: В статията са представени експериментални данни, получени при работата на два двигателя – Д 3900 и Volkswagen 1.9D, работещи по газо-дизелов работен цикъл. Газовото гориво, използвано при двигател Д 3900 е сгъстен природен газ – метан, a при двигателя Volkswagen 1.9D е втечнен петролен газ – смес от пропан и бутан. От проведените стендови изпитвания е установено влошаване на икономичните показатели при ниски натоварвания, като с увеличаване на натоварването икономичните показатели при работа двигателя по газо-дизелов работен цикъл се доближават до тези при работата му с конвенционално дизелово гориво. Наблюдава се повишаване на концентрацията на въглероден окис – СО, въглеводороди – CH, намаляване на концентрацията на азотни окиси – NOx и на димността на отработилите газове на двигателя, при работата му с добавка газово гориво. газово гориво.

Abstract: This paper presents an experimental results, obtained from the operation of two internal combustion engines – Perkins D3900 and Volkswagen 1.9 working on gas-diesel duty cycle. The gas fuel used in Perkins D3900 is compressed natural gas (CNG) - methane while the gas fuel used in Volkswagen 1.9D engine is liquefied petroleum gas (LPG) – a mixture of propane and butane. From the conducted experiments has been established that dual-fuel mode lead to increasing of the fuel consumption at low loads but with increasing the load there is no significant different between fuel consumption when engine work on dualfuel mode or operate with diesel fuel. There is increasing the concentration of carbon monoxide – CO, hydrocarbons – CH, reducing the concentration of nitrogen oxides – NOx and soot emissions in exhaust gas of the engine in dual-fuel mode.
