This study focuses on reducing the fuel consumption and exhaust gas emission values of the tractor used in the agricultural field. With the additive added to the fuel and the coating of the tractor engine, the fuel consumption values were reduced, and agricultural production costs were tried to be reduced. On the other hand, exhaust emission values were also tried to be reduced and thus a more environmentally friendly production method was aimed to be adopted. For this reason, the cylinders of the tractor engine were coated with Al2O3 + 13%TiO2 metal powders mixed by mass using the plasma spray method. All experiments were repeated by attaching these coated pistons to the engine. The fuel used in the experiments was purchased from a commercial company and the nanoparticle (molybdenum) additive was added to the biodiesel at the rates of 25 ppm, 50 ppm, 100 ppm, and 200 ppm by mass. The fuel mixtures obtained in the coated and uncoated engine, when the engine is in the full throttle position, using the PTO load test unit at 1000 rpm, 1200 rpm, 1400 rpm, 1600 rpm, 1800 rpm, and 2000 rpm. It has been tested by loading at 2200 rpm, 2400 rpm, and 2600 rpm engine speeds. Code for the Official Testing of Agricultural and Forestry Tractor Performance standards were adhered to during all engine tests. The results showed that coating the cylinders and adding nanoparticles into biodiesel reduces the fuel consumption value, increases the exhaust gas temperature, decreases HC, CO, and PM emissions, and increases NOx emissions.
