Tests have been carried out to evaluate the performance, emissions and heat release characteristics of a double cylinder direct injection diesel engine fuelled with tyre pyrolysis oil and diesel oil. The combustion parameters such as heat release rate, cylinder peak pressure, maximum rate of cylinder pressure, combustion knocking were also analysed. For purposes of this work raw pyrolysis oil was derived from waste vehicle tyres through vacuum pyrolysis realized in experimental installation. Results showed that the brake thermal efficiency of the engine fuelled with pyrolysis oil increased. THC, CO and CO2 emissions were found to be higher due to high aromatic content and longer ignition delay, whereas NOx shows increasing tendency due to greater heat release rate. The cylinder peak pressure did not change. The ignition delay became greater what can be the reason of problems with combustion knocking. Pyrolysis oil has a mass fraction of individual elements similar to diesel fuel but the chemical composition of hydrocarbons included in these fuels is different. The product of pyrolysis contains too much soot, sulphur, light and heavy hydrocarbons fractions for direct using it in engine. Aromatics content gives this fuel a distinctive smell. Pyrolysis oil is toxic and dangerous in use due to the polycyclic aromatic hydrocarbons (PAH). However raw pyrolysis oil is not suitable to use it as a CI fuel and requires additional distillation before using it in diesel engines as an alternative fuel in the future.
