Studies on Exhaust Gas of Agricultural Tractors on Field Work (Part 1)

Estimation of the Actual Situation of the Amount of Exhaust Gas by Reproduction of Field work

Abstract

The solution for the problem of exhaust gas from diesel engines has become more important these days, and some improvement is to be needed also on agricultural machineries. Therefore it is important to observe the actual situation of the exhaust gas amount of agricultural tractors on field work. On this report, rotary tillage was considered, which is the most popular work in Japan. To obtain the amount of exhaust gas, PTO Load on rotary tillage was recorded and reproduced with the PTO performance test system in the laboratory. PTO load and PTO speed were correctly reproduced on this system, and the tendency of the results of exhaust gas density by the system was the same as the real ones on the field, which means the reproduction of PTO load by the system is proper from the view of exhaust gas. By the reproduction, the exhaust gas amount of tractors was investigated on rotary tillage, and it supposed that the amount of exhaust gas per kWh varies with various required PTO power.
