Act means the Canadian Environmental Protection Act, 1999 . ( Loi ) adjusted loaded vehicle weight means the numerical average of a vehicle’s curb weight and its GVWR. ( poids ajusté du véhicule chargé ) approach angle means the smallest angle, in a plan side view of a vehicle, formed by the level surface on which the vehicle is standing and a line tangent to the front tire static loaded radius arc and touching the underside of the vehicle forward of the front tire. ( angle d’approche ) auxiliary emission control device means any element of design that senses temperature, vehicle speed, engine RPM, transmission gear, manifold vacuum, or any other parameter for the purpose of activating, modulating, delaying, or deactivating the operation of any part of an emission control system. ( (dispositif antipollution auxiliaire) ) auxiliary power unit means a device that is installed on a tractor and that is equipped with a diesel engine to generate power for purposes other than propelling the tractor. ( groupe électrogène d’appoint ) basic vehicle frontal area means the area enclosed by the geometric projection of the basic vehicle, which includes tires but does not include mirrors or air deflectors, along the longitudinal axis of the vehicle onto a plane perpendicular to that axis. ( surface frontale du véhicule de base ) break-over angle means the supplement of the largest angle, in the plan side view of a vehicle, that can be formed by two lines tangent to the front and rear static loaded radii arcs and intersecting at a point on the underside of the vehicle. ( angle de rampe ) CFR means the Code of Federal Regulations of the United States, as amended from time to time. ( CFR ) Class I motorcycle means a motorcycle having an engine displacement of less than 170 cm 3 . ( motocyclette de classe I ) Class II motorcycle means a motorcycle having an engine displacement of 170 cm 3 or more but less than 280 cm 3 . ( motocyclette de classe II ) Class III motorcycle means a motorcycle having an engine displacement of 280 cm 3 or more. ( motocyclette de classe III ) Class 2B vehicle means a heavy-duty vehicle that has a GVWR of more than 3 856 kg (8,500 lb) but less than or equal to 4 536 kg (10,000 lb). ( véhicule de classe 2B ) Class 3 vehicle means a heavy-duty vehicle that has a GVWR of more than 4 536 kg (10,000 lb) but less than or equal to 6 350 kg (14,000 lb). ( véhicule de classe 3 ) complete heavy-duty vehicle [Repealed, SOR/2015-186, s. 1] crankcase emissions means substances that cause air pollution and that are emitted to the atmosphere from any portion of the engine crankcase ventilation or lubrication systems. ( émissions du carter ) curb weight means, at the manufacturer’s choice, the actual or manufacturer’s estimated weight of a vehicle in operational status with all standard equipment, the weight of fuel at nominal tank capacity and the weight of optional equipment. ( masse en état de marche ) departure angle means the smallest angle, in a plan side view of a vehicle, formed by the level surface on which the vehicle is standing and a line tangent to the rear tire static loaded radius arc and touching the underside of the vehicle rearward of the rear tire. ( angle de sortie ) diesel engine means a type of engine that has operating characteristics significantly similar to those of the theoretical Diesel combustion cycle. The non-use of a throttle during normal operation is indicative of a diesel engine. ( moteur diesel ) diesel heavy-duty vehicle means a heavy-duty vehicle that is powered by a diesel engine. ( véhicule lourd diesel ) element of design means, in respect of a vehicle or engine, (a) any control system, including computer software, electronic control systems and computer logic; (b) any control system calibrations; (c) the results of systems interaction; or (d) any hardware items. ( élément de conception ) emission control system means a unique group of
