Представлены результаты исследований снижения токсичности отработавших газов автомобильного дизеля конвертацией на спирто-топливные эмульсии. При этом обоснована необходимость применения спирто-топливных эмульсий в качестве экологичного топлива. С целью разработки, определения и оптимизации состава спирто-топливных эмульсий проведены их испытания при работе дизеля на дизельном топливе, метаноло- и этаноло-топливных эмульсиях. Экспериментальными исследованиями установлено, что в автомобильном дизеле 4Ч 11,0/12,5 оптимальными для применения могут быть эмульсии следующего состава, %: спирт (метанол или этанол) – 25; моюще-диспергирующая присадка сукцинимид С-5А – 0,5; вода – 7; дизельное топливо – 67,5. Конвертация автомобильного дизеля с нефтяного дизельного топлива на метаноло-топливную эмульсию снижает содержание в отработавших газах сажи (С) в 6,9 раза, оксидов азота (NOx) на 41,3 %, диоксида углерода (CO2) на 6,7 %, оксида углерода (CO) на 45,0 %; на этаноло-топливную эмульсию – C в 5,2 раза; NOx на 50,2 %; CO2 на 23,8 %; СО на 25,0 %.

The results of the studies of reducing the toxicity of vehicle exhaust gases of car diesel by conversion to alcohol-fuel emulsions are presented. At the same time, the necessity of applying alcohol-fuel emulsions as an environmentally friendly fuel is grounded. In order to develop, determine and optimize the composition of alcohol-fuel emulsions, their tests were carried out when the diesel engine is operated with diesel fuel, methanol and ethanol-fuel emulsions. Experimental studies have established that in car diesel engine 4 Ч 11,0/12,5, emulsions with the following composition may be optimal for use, %: alcohol (methanol or ethanol) – 25, detergent-dispersant additive succinimides C-5A -0.5, water – 7, diesel fuel – 67.5. Conversion of car diesel from diesel oil to methanol-fuel emulsion reduces the content of carbon black (C) in exhaust gases by 6.9 times, nitrogen oxides (NOx) by 41.3 %, carbon dioxide (CO2) by 6.7 %, oxide carbon (CO) by 45.0 %; on the ethanol-fuel emulsion – C in 5.2 times, NOx by 50.2 %, CO2 by 23.8 %, CO by 25.0 %.
