The Effect of Diesel Fuel Improvers on the Vibrations, Noise and Fuel Consumption of the Agricultural Tractor Engine During the Tillage Process

Abstract

The research aims to study the effect of the fuel type, plow types, and engine speeds on Tractor Seat Vibrations (TSV), Noise of Agricultural Tractors(NAT), and fuel consumption. The field experiments were conducted on an experimental farm in Al-Hamdaniya, Nineveh province, Iraq. The investigation was factorial, using a Randomized Complete Block Design with Split –Split plot Design. The trial site was divided into 18 treatments with three replications for each treatment; the length of the treatment was 180 meters, with an affixed depth of 25-30 cm. The three types of fuel type were placed in the main plot, the plow types in the secondary split plot, and the speed engine in the Split -Split plot. The results showed significant differences between the fuel, plows, and engine speeds in most studied traits. The triple interaction of the diesel without Additives and disk plow with speed engine 1500 rpm was significantly superior and recorded the lowest in the trait of TSV (2.605 m. s−2) and the characteristic of NAT (89.449 dB) while the highest value of fuel consumption (32.710 L. ha−1). The interaction of the diesel with Mannol super additives, disk plow, and speed 2000 rpm was recorded as the highest value of TSV (6.944 m.s−2). as well as the highest value of NAT (92.166 dB) at the interaction of the diesel without additives, disk plow and speed engine 2000 rpm. The lowest fuel consumption rate (25.307 L. ha−1) with a significant difference at the interaction of the diesel with Mannol super additives, moldboard plow, and speed engine 2000 rpm.
