摘要： An all-terrain vehicle (ATV) has a frame having front and rear ends, an internal combustion engine connected to the frame, the engine including a front portion and a rear portion, a single cylinder defining a cylinder axis, an air intake port defined in the front portion facing towards the front end of the frame, and an exhaust port defined in the rear portion facing towards the rear end of the frame. The ATV further has an exhaust assembly fluidly connected to the exhaust port. The exhaust assembly extends from the engine towards the rear end of the frame. The ATV further has a continuously variable transmission operatively connected to the engine, which includes a primary pulley being operatively connected to the engine, a secondary pulley, a drive belt looped around the primary and secondary pulleys, and a housing enclosing the primary pulley, the secondary pulley, and the drive belt.

摘要： A method for controlling engine braking in a vehicle comprises: determining a position of a throttle operator; determining a speed of the vehicle; and determining an engine braking mode selected. In response to the position of the throttle operator being a fully released position and the selected braking mode being a first engine braking mode: controlling an engine and a position of a throttle valve according to the first engine braking mode for applying a first level of engine braking. In response to the position of the throttle operator being the fully released position and the selected braking mode being the second engine braking mode: controlling the engine and the position of the throttle valve according to the second engine braking mode based at least on the speed of the vehicle for applying a second level of engine braking. A vehicle implementing the method is also disclosed.
