Abstract
It is desirable for engines to produce high torque in lower speed ranges. Such conditions are encountered when vehicles climb gradients. Two techniques are compared in this paper along with their merits and demerits to improve torque of a CI engine for lower speeds.
The first method increases swirl at lower speed whereas the second method uses a combined charging system to improve airflow rates.
Matching of Turbocharging equipment with diesel engine throughout the operating speed range has also been discussed in this paper. Combining both methods, provides excellent torque characteristics at lower speeds without increase in smoke and other emissions. This improves driveability of the vehicles.
