The present invention relates to a method for controlling the speed of a motor vehicle, a speed control system and a device for use with the speed control system. For improving the fuel economy, the method comprises monitoring at least one speed-related parameter of the vehicle (2), determining a nominal speed based on said speed-related parameter, setting the engine (3) of the vehicle (2) in a driving mode or an idle mode at said nominal speed, setting the engine (3) of the vehicle (2) in an idle mode when the actual speed of the vehicle exceeds said nominal speed, setting the engine (3) of the vehicle (2) in the driving mode when the actual speed of the vehicle decreases to said nominal speed or falls below said nominal speed, and repeating, based on said fluctuations of the actual speed of the vehicle, said changes between driving mode and idle mode as long as the monitored speed-related parameter is substantially unaltered. The speed control system used at this method comprises at least monitoring means (4), calculating means (6) and setting means (8).

The present disclosure relates to a bonnet deployment arrangement (11, 11', 11 ") adapted to be located at an end portion (17) of a bonnet (5) of a vehicle (3). The bonnet deployment arrangement is transferable from a normal state to a deployed state and comprises a first portion (19, 19', 19") adapted to be attached, directly or indirectly, to the bonnet, a second portion (21, 21', 21 "), comprising one of a striker (15) or a latch for retaining the bonnet in a closed position, a pivot arm (23, 23', 23"), and a locking unit (25, 25', 25") having a locked state and an unlocked state. The pivot arm is rotatably connected to the first portion at a first axis (A1, A1") and rotatably connected to the second portion at a second axis (A2, A2"). The first portion is locked relative to the second portion in the locked state of the locking unit. The first portion is movable in relation to the second portion by means of the pivot arm rotating at the first axis and at the second axis in the unlocked state of the locking unit, the bonnet deployment arrangement thereby being transferable from the normal state to the deployed state. The invention also relates to a bonnet arrangement for a vehicle and to a method of transferring a bonnet deployment arrangement from the normal state to the deployed state.

The invention relates to a method for operating a compression ignition internal combustion engine (10) including at least one combustion chamber (18) with a fuel injector (20) for direct fuel injection into a combustion chamber (18), an electronic control unit (ECU) for controlling the fuel injector, and a glow plug (26) for assisting compression ignition of the fuel and combustion air mixture supplied to the combustion chamber (18) in a start phase (T). The method involves performing a by injecting a start-up pilot fuel quantity, prior to a stratified injection, by means of the fuel injector (20) into the combustion air supplied to the combustion chamber (18) during a cold start of the internal combustion engine (10), said start-up pilot injection (PS) forming a homogeneous, lean air/fuel mixture in substantially the entire combustion chamber (18). The start-up pilot injection is performed during a period between initialization of a cranking phase of the internal combustion engine until at least one predetermined engine operating condition has been fulifilled.
