Chevrolet Boost Duramax Diesel Engine Performance

Bangkok - Duramax Diesels latest pacemaker implanted as Trailblazer and Colorado , claimed General Motors ( GM ) is more resilient . According to Jim DeLuca , Vice President of Manufacturing General Motors International Operations , at a press conference , yesterday ( 28/11/2013 ) , the change is not due to consumer complaints , but to refresh the already well underway .

" The market reaction was very positive with the old Duramax engine . Now we want to give something new , the engine is more economical and tough . We want to raise the level, of the good being very good , "said DeLuca .



Difference
Better engine performance can be seen in the following comparison . 2.800cc engine power and torque is now 200 PS and torque of 500 Nm ( previously 180 PS and 470 Nm ) . As for 2.500cc , power and torque increased to 163 PS and 380 Nm ( previously 152 PS and 350 Nm ) .

Improved performance due to work pressure injector in the " common-rail " raised to 2,000 bar ( 29,000 psi ) over . To improve the robustness turbo - in this case the variable geometry turbocharger - didmaksimalkan cooling system . Materials uintuk suction channel ( intake manifold ) is now made ​​of plastic and the cylinder head is also more lightweight . Exhaust is also changing , larger diameter . The goal for more efficient cooling .

To reduce engine vibration , added balancer shafts . While your computer or ECM which controls the engine work , work more quickly and accurately to maintain peak engine performance . Both have reached the Euro - 4 emission standards , and could be raised to Euro - 5 or 6 if necessary .

Transmission
Both engines , coupled with the new 6 - speed . Comparison of teeth adapted to changes in engine performance are more powerful and efficient . For the 4X4 version , the turn motion system , can be done while sliding ( shifted on-the - fly ) without making a sound .

Accelerated capabilities , a maximum speed of 180 kph to 2,800 cc engine with automatic transmission and acceleration from 0-100 kph in 10.6 seconds , fuel consumption 10.6 kpl . As for the 2,500 cc engine manual transmission , acceleration of 11.7 seconds , fuel consumption 12.8 kpl .
