2 Fundamentals of Fuel Consumption | Assessment of Fuel
Before proceeding, it is necessary to define the terms fuel economy and fuel consumption; these two terms are widely used, but very often interchangeably and incorrectly, which can generate confusion and incorrect interpretations:. Fuel economy is a measure of how far a vehicle will travel with a gallon of fuel; it is expressed in miles per gallon. This is a popular measure used for a long

CO2 emissions and energy consumption of loaders in
Feb 01, 2018 · Third, the front-end loaders, although very productive, require a much larger work space than classic knuckle-boom loaders, with a turret that pivots on the base carrier. In constrained-space landings, a front-end loader would be unable to work, or slowed down by the need for repeated accurate manoeuvring to handling the woodchip. 5. Conclusions

Fuel Efficiency Guide For Heavy Machinery
After wages, fuel costs are the next highest expense on most sites. Reducing idling prolongs equipment life and lowers overall maintenance costs. 4- to 6-yard wheel loaders have the largest Tier 4 Final fuel efficiency gains. Maintaining proper tire inflation can help save on fuel costs—under-inflation by just 6 psi consumes 3% more fuel.
