METHOD FOR CONTROLLING A COMBUSTION ENGINE TO DECELERATE A VEHICLE
Abstract:
A method and vehicle embodying the method are provided for deceleration of a vehicle comprising a combustion engine comprising at least one cylinder to which fuel is supplied, a piston in each cylinder, at least one inlet valve in each cylinder, which is connected with an inlet system, a first camshaft controlling the inlet valve, at least one exhaust valve in each cylinder, which is connected with an exhaust system, a second camshaft controlling the at least one exhaust valve and a crankshaft controlling each camshaft. The method comprising a) closing the fuel supply to all cylinders, b) phase-shifting each camshaft in relation to the crankshaft to a position where no air is supplied to the exhaust system when the pistons move forwards and backwards in each cylinder, and c) controlling a gearbox to engage a gear that increases the crankshaft's rotation speed, which decreases the vehicle's speed.
