Abstract
It has been well documented that the performance of an engine can be adjusted through altering the design of the air intake system. A full four stroke Otto cycle is an unsteady cycle with the continuous charging and discharging of the intake system. The characteristics of airflow within the inlet system can be described as a function of frequency. This frequency can be altered to aid in increasing the volumetric efficiency (VE) of the engine at a desired point/s. This paper reviews the air intake system used by Dave Molyneux Racing (DMR) for their sidecar racing in the Isle of Man Tourist Trophy (TT). An iterative design process found that the airbox design needed the intake pipe to be as straight as possible and facing the free stream flow. Turning vanes were used in the intake pipe and airbox to aid in ensuring uniform pressure across the four bell mouths of the intake system.
