Tube catalyst (TK^plus) to crack gasoline fuel vapor in motor vehicle

This study aims to test ability the catalyst tubes to reduce exhaust emissions, save fuel and increase power and torque engine on vehicle. The catalyst tube named TK^plus. TK^plus catalyst tube filled with NiFe₂O₃ which was created with sol gel method and calcined on temperature 600°C, characterized by XRD, FTIR, SEM EDX, and BET test. Exhaust emission test results show motor vehicles equipped with TK^plus can reduce CO₂ emissions; between 36% - 48%, and CO₂ emissions fall between 7% - 42%, decrease fuel consumption by 23% - 33%. Dyno test shows that in the presence of TK^plus engine performance increased compared with engine without TK^plus. At the revolving round of the engine at 5781 rpm or at a speed of 120 km/h, the power value increased by 5.8% and the torque value increased by 7.8% compared to the vehicles not equipped with TK^plus value.
