This Efficiency Program is design to encourage the skilled truck drivers in a way to save precious fuel during their work shift. The main objectives of FEBB are: 1st The transportation and forwarding companies offer an incentive to its drivers that called FEBB program: It means all fuel savings will transformed to driver bonus monthly payment additional to its basic salary. How it is calculate? All engines have technical specification by producer state the average urban or highway fuel consumption. All below those specifications are fuel savings. You simply multiply the fuel saving in litters or gallons by the fuel price at the middle of the month (to monthly eliminate standard deviation of fuel price). How the drivers do savings? - The skilled driver would adjust the vehicle speed not only accelerating the engine but most with switching the gear while the engine is working at its optimum of rotational force (torque); 2nd It is announced as incentives to SKILLED DRIVERS, which predefined that only drivers saving fuel are skilled. That will change driver mentality to more economic and environmental safety manner. Benefits: 1. You can lower fuel consumption in average vary from 1 litter/100kms for engines below 2000cc to 5 litters/100kms for heavy engines over 12,000cc; 2. Environmental more safety; 3. Encourage the drivers not to exceed speed limits because fast driving means higher fuel consumption. Conforming with speeds limits will decrease the road incidents; 4. Engine's and suspension system physical depreciation is lower. The lower depreciation the lower costs of maintenance; 5. More cost-effective routing is chosen by the driver in order to save fuel; 6. In some countries it will reduce the fuel pilferage. Common phenomenon in south-east Europe; 7. Fuel save = Bonus Payment = Motivation.
Application: Effective: In countries where the highway network is well developed; Ineffective: In urban environment where a lot of maneuvers are required during transportation. Broad application: Automotive industry: this theory leads to the term Economic Drive Gear System (EDGS). In general it is 12-18 gear automatic transmission system that is working on maximum of moment (torque) in terms of RPM. How it works? - The transmission changes the gear up when the RPM moves up with more than 10% vs. ORPM and the transmission changes the gear down when RPM drops down with more than 10% vs. ORPM. * ORPM = optimum of revolutions per minutes (see Prerequisites for the theory). Prerequisites for the theory (the following facts are well known but fundamental for FEBB theory and could be defined as Axioms): 1. Newton metre is the unit of moment (torque**) of self propelling internal combustion engines. The maximum of moment (torque) for diesel engines is achievable with the range of 1000-2000 rpm that could differ from one producer to another. The best engines are those that have wider range of revolutions per minutes (rpm) while keeping the maximum of the moment (torque). The driver can adjust the speed of the vehicle switching to higher Gear for higher speed through engine acceleration in a range of ORPM and vice versa. Herein we will call this maximum of torque in terms of rpm as ORPM Optimum of Revolutions Per Minutes. ** Torque = rotational force (Nm). 2. While keeping the maximum of moment (torque) in terms of RPM it results in lower depreciation of the engine and better combustion and lower emission of CO and (HC NOx) where NO-Nitric Oxide is toxic air pollutant.
Example table of correlation between RPM (r/min), Torque (Nm) and Engine power (kW) is given below.
