Subtopic: Power efficiencies and measurement, engine performance curves
Question Statement:
During an OECD drawbar test on concrete track, a tractor delivers a steady drawbar pull of $18.0\text{ kN}$ at a travel speed of $5.4\text{ km/h}$ ($1.5\text{ m/s}$). During a 1-hour test run, the tractor consumes $7.2\text{ kg}$ of diesel fuel. Calculate the specific drawbar fuel consumption in $\text{g/(kW}\cdot\text{h)}$ (round off to 1 decimal place).
