Effect of tyre derived oil-diesel blend on the combustion and emissions characteristics in a compression ignition engine with internal jet piston geometry

摘要: Abstract In recent years there have been significant developments seen in utilization of different derivatives obtained from pyrolysis waste automobile tyres, as alternative fuels for CI engines. an investigation, a blend comprising 40% light fraction oil tyre recycling plant, 50% diesel and 10% oxygenate additive Dimethyl carbonate (40LFPO + 10DMC) was examined fuel single cylinder, direct injection (DI) compression ignition (CI) engine. Even with the additive, 40LFPO exhibited inferior performance higher smoke emission than those operation at full load same Turbulence inducement is one methods to improve combustion behavior Therefore, this attempt made create more turbulence chamber by providing internal jets piston, when engine run 40LFPO10DMC. The investigation results terms combustion, emissions were compared conventional without inducement, presented paper. hydrocarbon (HC), carbon monoxide (CO) found be reduced about 32.9%, 66% 13% respectively, piston load, while they lower 66.6%, 2.4% 21.2% fueled jet load. brake thermal efficiency 40LFPO10DMC improved that 40LFPO. It 4.5% 5.3% respectively
