The most common heavy-duty vehicles for moving huge quantities of goods in both urban and rural locations are container lorries. The number of hazardous pollutants in the environment has dramatically increased as a result of the huge capacity engines on this vehicle. To solve, it makes more sense to think about enhancing vehicle design to boost aerodynamic efficiency as opposed to other worries. However, it is impossible to make significant changes to these heavy-duty vehicles without influencing how much cargo space they can hold since the original container shape is standardized worldwide. Therefore, a cylinder is proposed to be fitted onto the lorry to reduce the drag force acting on the container lorries. Thus, this study is focused on experimenting on the effects of a static cylinder that blends in with an existing container lorry model, the Mercedes Benz Actros together with a roof fairing with fenders and aims to reduce its drag force by finding the right position for the cylinder. In this research work, a study is conducted using the wind tunnel to prove the effectiveness of cylinders in reducing drag of container lorries by different cylinder position configurations. According to the experiment, Cylinder Position 2B and Position 5 are the best configurations to reduce Cd acting up the lorry.
