1. Ecology & Economy
Design features of SAA6D114E-3 engineNew combustion technology ICS (in-cylinder-solution) reduces NOx emission without using EGR.
4-valve (per cylinder) system to increase cylinder intake air flow.
Injection nozzle arranged at cylinder center to effectively use the air contained in cylinder (to promote fuel-air mixing)
The common rail fuel injection system assures high-pressure fuel injection in low-speed range to increase low-speed torque.
Electronic-controlled high pressure fuel injection system realizes both low NOx emission and high performance.The exhaust color density during acceleration is also reduced.
