Sentences with phrase «increased fuel atomization»
As diesel engine speeds and loads increase, the higher cylinder temperatures after compression of the intake charge result in increased injection and ignition efficiency due to increased fuel atomization.

Features include two - step variable valve lift, cooled EGR, upgraded variable - valve timing, a new intake manifold, high - tumble intake ports, shrouded combustion chambers, eight - hole fuel injectors with optimized atomization, multiple friction - reduction features, and an increased compression ratio of 11.3:1 (but still only requires 87 octane fuel).
The valves are cut to allow air past even when fully - closed, but since they restrict the cross-sectional area of the intake runners, the velocity of the incoming air is increased, resulting in better fuel atomization in idle and low - engine - speed conditions.
These injectors optimize the fuel spray pattern, and improve fuel atomization for increased fuel mileage and reduced emissions.
