��There is opportunity to replace existing gear-transmissions of heavy-duty trucks and to get  unbelievable-believable benefits ( There are the 260 ��utually definite units of energy for forced energy economy��(MDUFEE) shift gearbox families (above 1,000 state-of-the-art designs) for all machines as vehicles based on land, water, under water, air, heavy-duty equipment, CNC/universal machine tools, and conveyer systems. It has patent #7,191,676, patent application #20080047380 have been disclosed at www.uspto.gov, and filled out second patent application that also has not been published.):
1) Reducing manufacturing costs because innovation has up to 40% less gears;
2) Reducing engine fuel consumption because innovation limit or eliminate acceleration system inside of engine that has only idle speed of shaft;
3) Reducing emissions more than 50%;
4) Full loaded heavy-duty truck will have increased speed on uphill in 2 times.
5) Eliminating oxides of nitrogen ( NOX) from engine that never will has heat more than 254C because heavy-duty truck have been accelerated by MDUFEE gearbox apparatus-accelerator.
