Fuel measurement: The fuel efficiency was measured by the
fuel consumed during field operations. Fig. 2 shows the cycle
structure of fuel supply of the tractor. The fuel pump initiated
fuel flow through the fuel supply line, connected fuel filter and
lift pump, to the cylinder. The remaining fuel was released to
the fuel tank through the fuel return line. A gear flow meter for
high-precision measurement (M05, NURITECH, Korea) was fitted
between the fuel tank and fuel filter to measure the fuel
consumption during plow tillage operations 2
. The measuring
ranges of flow meter were 0.003 - 0.8 /min and the pressure
limit was 5.5 MPa. The gear flow meter was suitable to measure
the fuel consumption considering tractor fuel efficiency 2
. The
fuel flowing through the fuel pump was injected into the cylinder,
and the remaining fuel was returned to the fuel tank at the existing
fuel cycle structure. For this reason it is difficult to measure the
exact amount of fuel in real time. Thus, a fuel return control valve
was mounted on the fuel return line to send the remaining fuel
into the fuel supply line, which made the exact measurement of
fuel consumption 13. The amount of fuel consumed was calculated
by subtracting returned fuel through the control valve from the
total fuel circulated through the fuel supply line.
