Description

EXAMPLE I

(1) An AUDI Q7, 4.2 l, petrol engine, built in 2013 and equipped with a catalyst, fulfilling the EU exhaust gases requirements was subjected to a drive cycle EPA US 06. The drive length was 12 km.

(2) The car has been filled with conventional gasoline, ROZ 95 and subjected to the test while determining the amount of CO and HC, which is set to 100% as reference.

(3) Prior to starting an experiment with a fuel, the car was depleted from the previous fuel, refueled with the new fuel and run for 15 minutes at idle speed with the respective new fuel to warm the motor and fill all lines and the engine with the respective fuel to be tested.

(4) Experiments have been carried out with additives according to the invention (embodiments 1-3, 6-8) and with additives, wherein the amount of individual components are not within the limits indicated or where a fuel component was replaced by another component (embodiments 4-5).

(5) The respective compositions have been added to fuel in a ratio of roughly 1:10.000 prior to filling the car.

(6) The exhaust gases were analyzed for C and HC and the amount of CO and HC determined with the fuel+additive was indicated in percentage reduction as compared to the reference.

(7) Additives:

(8) TABLE-US-00001 1. M 1 Isoprop. = 65%, D = 17%, B = 16% W = 2%. 2. M 2 Isoprop. = 65%, D = 17%, B = 15%, W = 3%. 3. M 3 Isoprop. = 70%, D = 14%, B = 14% W = 2%. 4. M 4 Isoprop. = 55%, D = 20%, B = 22%, W = 3%. 5. M 5 Isoprop. = 65%, D = 15%, B = 15%, W = 5%. 6. M 6 Isoprop. = 65%, techn. lineseed B = 12%, W = 3%. oil = 20%, 7. M 7 Isoprop. = 65%, techn. lineseed B = 10%, W = 5% oil = 20%, 8. M 8 Isoprop. = 65%, techn. lineseed B = 16%, W = 2%. oil = 17%, Isoprop. = isopropanol; D = diesel; B = gasoline; W water.

(9) The following results have been obtained:

(10) TABLE-US-00002 1. CO 39%, HC 28%. 2. CO 37%, HC 27%. 3. CO 32%, HC 24%. 4. CO 18%, HC 15%. 5. CO 29%, HC 21%. 6. CO 38%, HC 28%. 7. CO 33%, HC 25%. 8. CO 39%, HC 28%.

(11) As may be seen, all compositions produced an decreased level of CO. However, in case the amount of isopropanol exceeds the lower level of 60 vol.-% or the amount of water exceeds the upper limit of 3 vol.-% the amount of HC is increased. Good results are also achieved when replacing diesel with technical lineseed oil.

EXAMPLE II

(12) A similar experiment has been carried out with a Hyundai i30, built in 2010, diesel engine, and equipped with a catalyst, fulfilling the EU exhaust gases requirements was subjected to a drive cycle. The drive length as 11 km. The following additive has been prepared:

(13) TABLE-US-00003 Isopropanol 660 ml Diesel 160 ml Benzin 160 ml Water 20 ml Urea 3 ml

(14) The additive has been added to the diesel fuel in a ratio of 1:10.000.

(15) Exhaust gases have been determined according to 70/220/EWG i.d.F. 98/69/B/EG.

(16) The following results have been obtained as compared to the reference (diesel without additive);

(17) TABLE-US-00004 City Countryside CO 73% 16% HC 45% 31%.
