dc.description.abstract1We have conducted experimental study into parameters of the piston engine 1Ch 6.8/5.4 with forced ignition operated on ethanol with different additives of the synthesis-gas in the amount to 10 %. We used the methods of working cycle indication, as well as registering the thermal balance of the engine, which make it possible to obtain the most complete pattern that characterizes ethanol combustion with additives of the synthesis-gas, as well as to determine the relationship and influence of the composition of an additive on the basic parameters of the engine working cycle. We have acquired and processed experimental indicator diagrams under different modes when the engine was operated with and without additives of the synthesis-gas. It was found that the engines with spark ignition operating on ethanol with additives of the synthesis-gas in the amount to 10 % demonstrate a decrease in the indicator work and specific indicator fuel consumption. A decrease in the indicator engine performance can be resolved by using small amounts of additive of the synthesis-gas for heavy loads, and maximal amounts of additives at low loads. It was determined that significant additives of the synthesis-gas to ethanol results in an increase in the maximum pressure of combustion by up to 12 % and its shift towards the upper dead point at 7° c.s.r. Increasing the additive of synthesis-gas to ethanol by larger than 10 % requires adjustments of excess air ratio and the ignition advance angle. When using the synthesis-gas additives to ethanol, the ethanol specific effective consumption reduces by 2.5...12.4 %. The obtained experimental data can be considered with a sufficiently high degree of accuracy to be correct for engines with spark ignition and a cylinder volume of 190...250 cm3. The quantitative and qualitative results of experimental studies that we obtained have confirmed the effectiveness of using the additives of synthesis-gas to ethanol; they would also complement a mathematical model of the working cycle with empirical coefficients and dependences for each particular case.uk_UA
