Abstract
|
|
|---|---|
| A general goal of more energy efficiency encourages the use of tractors with better energy performance. Energy losses in agricultural tractors occur principally in the engine and secondarily in the transmission. In a previous article the authors proposed an efficiency index (cjt) using some theoretical assumptions and applied it for 214 models of tractors sold in Spain by mid¿2006. In this article a new efficiency index (ckt) that better represents the relationship between fuel consumption and available energy in the tractors was derived from official tests that follow the OECD codes. This index also considers the rolling resistance to establish the transmission coefficient, and includes tractors with CVT (continuous variable transmission) taking into account the specific characteristics of this transmission. | |
