Vehicle installation. 3.4.1. The vehicle shall be approximately horizontal during the test so as to avoid any abnormal distribution of the fuel. 3.4.2. A current of air of variable speed shall be blown over the vehicle. The blower speed shall be such that, within the operating range of 10 km/h to at least 50 km/h, the linear velocity of the air at the blower outlet is within ±5 km/h of the corresponding roller speed. The final selection of the blower shall have the following characteristics: (a) Area: at least 0.2 m2; (b) Height of the lower edge above ground: approximately 0.2 m; (c) Distance from the front of the vehicle: approximately 0.3 m. As an alternative the blower speed shall be fixed at an air speed of at least 6 m/s (21.6 km/h). For special vehicles (e.g. vans, off-road), the height of the cooling fan can also be modified at the request of the manufacturer.
