Abstract
As the emission targets are getting tighter, efforts are made to
improve the emission by all possible means. This work emphasis the
potential of intercooler to reduce exhaust gas emissions (CO, HC,
NOx and PM). A detailed analysis of experimental results on
emissions is presented. The effect of intercooler efficiency on
emissions is explained. A multi-utility vehicle equipped with
common rail diesel engine was tested in NEDC cycle in chassis
dynamometer. Ideally the vehicle emission lab should replicate a
flat straight road condition & natural airflow. To obtain the
airflow a variable velocity fan is used. The velocity of air
emerging from the fan and relative position of the fan with vehicle
has a significant role in intercooler efficiency and hence on
emissions. This work explains the exercise carried out to correlate
the intercooler efficiency and exhaust emissions with fan position
and velocity. Trials were conducted on road as well as on vehicle
emission laboratory and the fan position and velocity was optimized
based on best results.
