POSSIBILITIES OF SAVING FUEL

Possibilities of reducing fuel consumption in trucks and buses are presented which are controlled by the appropriate driver response, in particular driving style and discipline, optimal use of the technically feasible qualities of the vehicle and conscious checking, and maintenance of the components. The technical background is described. Behaviour patterns leading to economical driving are:- anticipatory driving, selection of the optimal speed, correct usage of the gear steps including preselectors and overriders, avoidance of frequent and intensive braking, gentle acceleration, use of the engine brake, not allowing the engine to idle for longer than one minute at temperatures below 0 deg C and 30 seconds at temperatures above 0 deg C (3 minutes idling time for vehicles with compressed airbraking). Examples, with figures of fuel savings, are discussed. Economical speed ranges of seven trucks and buses are listed. A detailed list is given of vehicle factors which may have an unfavourable effect on fuel consumption, their detection and correction. It is suggested that fuel savings obtained by a works driver should be rewarded. The original paper (in German) was published in Kraftfahrzeugtechnik, December 1977. /TRRL/
