Opis:
The article presents a comparative analysis of heat release rate in a spark-ignition engine powered by various fuels as follows: butanol, gasoline, a mixture of butanol with tire pyrolysis oil (TPO), and mixtures of butanol with oil from biomass pyrolysis (BPO). Selected combustion phases were analyzed. Additionally, ignition delay calculations were performed in the ANSYS Chemkin Pro program for the surrogates of the tested fuels. Popular surrogates quoted in numerous publications were used as substitute fuels. The paper presents an original surrogate of oil from tire pyrolysis.

Opis:
Pyrolysis oil obtained from thermal biomass processing (torrefaction and pyrolysis) was used as an additional fuel for the compression-ignition engine equipped with a classic (non-common rail) injection system. The basic fuel used to the engine was regular diesel fuel. The tests were carried out with two content of pyrolysis oil in diesel fuel as follows: 10 and 20% by volume. In addition, the combustion process was investigated in the engine operating only on pyrolysis oil. The test results were based on a comparative analysis, where the diesel fuel was used as the reference fuel. The obtained results indicate that is a real possibility of co-combustion of pyrolysis oil with diesel fuel in the CI engine. On the other hand, a decrease in engine power resulting from the lower calorific value of pyrolysis oil and a greater unrepeatability of engine consecutive work cycles were observed.

Opis:
The article presents results of investigation on the combustion of a mixture of pyrolysis oil from tires and regular fuel in the internal combustion reciprocating piston engine. The tested fuel consisted of: diesel fuel and pyrolysis oil at amount of 10% by volume. The tests were carried out on a single-cylinder naturally aspirated compression-ignition engine. The engine was equipped with a common rail fuel injection system and an electronic control unit that allowed changing injection timing. A comparative analysis of pressure-volume charts for the reference fuel, which was diese fuel, and for a mixture of diesel with 10% addition of pyrolysis oil was carried out. Injector characteristics for the reference fuel and the mixture were determined. Engine efficiency for both fuels was also determined. Unrepeatability of the engine work cycles for the diesel fuel and the tested mixture was calculated. Finally, exhaust toxic emission was analyzed. It was found that the pyrolysis oil can be used as valuable additive to regular diesel fuel at amount up to 10%, however, toxic exhaust gases emission was increased.
