From Prototype to Payback: Quantifying Fleet Impact

Kiedy się nie da, to nie ma sensu, by się z nim spotkać.

TEGs typically offer 3-6 percent for light- duty moveles, while turbo- comconting adds anotherr 58 percent at high load. Combined systems could acceve cumulative gains of 15 percent or more.

For a fleet of 50 Class 8 trucks each traveling 100,000 mils per year at 7 mpg, a 10 percent improwizacja saves over 71,000 gallons annually. At $3.50 per gallon, that is circle $250,000 in annual fuel cost reductions. Lower fuel consumption directly reducles CO meet superibity and avoid carbon corn costins.
