Review Paper on Effect of Humidity on IC Engine Performance and Emission Characteristics
Keywords:
Humidity, Engine performance, Emission, Ambient condition, IC EngineAbstract
This work investigates the effect of inlet air humidity changes on the specific power output, specific fuel Consumption and the
emissions of nitric oxide and smoke from IC engine. Ambient conditions depend on the geographical location and may vary with
time of the year. Engine controls may compensate for some effects of these variations, but engine performance deviations are to
be expected generally higher humidity lowers combustion rates and decrease peak temperature and pressure that’s why car’s
performance is much better in winter than summer. Although humidity effects on engine performance, it effect becomes
significantly lower with increase combustion temperature. This work also included effect of humidity on engine performance at
high altitude.
