Effect of tyre derived oil-diesel blend on the combustion and emissions characteristics in a compression ignition engine with internal jet piston geometry
“…They also reported that the lower heat release rate (HRR) during the premixed combustion phase is the reason for the lower thermal efficiency of TPO fuel operation up to part load.

“…Tudu et al . 15 reported that the higher density of TPO fuel (910 kg/m 3 ) compared to diesel (830 kg/m 3 ) results in poor atomisation and spray characteristics, causing incomplete combustion of fuel. Wamankar and Murugan 51 also concluded that the higher density and viscosity of carbon black led to poor atomisation, thus, had higher BSFC compared to diesel.…”

With an increase in blending ratio, CO emissions gradually increased compared to diesel, although attempts have been made to decrease the CO emissions with use of TPO by blending it with other fuels such as biodiesel 15 , 57 .

“…Tudu et al . 15 concluded that using 10% dimethyl carbonate (DMC) in light fraction pyrolysis oil resulted in a 66% reduction in CO emissions. This could be due to the additional oxygen content of DMC, resulting in a more homogeneous mixture of air-fuel resulting in more complete combustion.…”

The disposal of waste rubber and scrap tyres is a significant issue globally; disposal into stockpiles and landfill poses a serious threat to the environment, in addition to creating ecological problems. Fuel production from tyre waste could form part of the solution to this global issue. Therefore, this paper studies the potential of fuels derived from waste tyres as alternatives to diesel. Production methods and the influence of reactor operating parameters (such as reactor temperature and catalyst type) on oil yield are outlined. These have a major effect on the performance and emission characteristics of diesel engines when using tyre derived fuels. In general, tyre derived fuels increase the brake specific fuel consumption and decrease the brake thermal efficiency. The majority of studies indicate that NOx emissions increase with waste tyre derived fuels; however, a few studies have reported the opposite trend. A similar increasing trend has been observed for CO and CO2 emissions. Although most studies reported an increase in HC emission owing to lower cetane number and higher density, some studies have reported reduced HC emissions. It has been found that the higher aromatic content in such fuels can lead to increased particulate matter emissions.
