3 Terms and definitions
There are no terms and definitions that need to be defined in this document.
4 Evaluation index of tractor fuel economy
See Table 1 for the evaluation indexes of tractor power output shaft fuel consumption rate and traction specific fuel consumption. For no power output shaft or unsuitable for power output
For tractors with axle test, the diesel engine fuel consumption rate shall be assessed according to the provisions of Chapter 7 of GB/T 28239-2020.
Table 1 Fuel economy evaluation indicators of wheeled tractors
Transmission type rated power/kW
Weighted power output shaft fuel consumption rate
g/(kW·h)
Weighted traction specific fuel consumption
g/(kW·h)
Multi-cylinder direct drive
≤22.1 ≤330 ≤365
>22.1~< 73.5 ≤315 ≤350
≥73.5~< 147.0 ≤342 ≤380
≥147.0 ≤330 ≤365
Single cylinder direct drive-≤315 ≤350
Belt drive-≤330 ≤365
Note. The power section of the direct drive tractor is consistent with JB/T 11320-2013.
5 Test method
5.1 Under the test equipment and test conditions specified in GB/T 3871.3, the fuel consumption rate test of the power output shaft shall be in accordance with the working conditions specified in Table 2.
