Abstract: A phase-shifting device, a so-called cam phaser, is arranged between a crankshaft and at least one camshaft to change the at least one camshaft's rotational position in relation to the crankshaft and thus push forward or defer at least one inlet valve's and/or at least one exhaust valve's opening and closing time. The phase-shifting device is connected to an accumulator that can be charged by an oil pump. The oil pressure may be increased with the help of a pressure medium controlled cylinder before or during a phase-shifting process.

Abstract: A control arrangement and a method for shutting down a combustion engine of a powertrain of a vehicle are disclosed. The vehicle comprises an intake air throttle arranged in an intake pipe of the combustion engine, and at least one auxiliary brake selected from the group consisting of; an exhaust brake and an electrical machine configured to operate as a generator. The method comprises in response to a command for shutdown of the combustion engine, stopping fuel injection to the combustion engine; controlling the intake air throttle so as to reduce the air intake to the combustion engine; and activating the at least one auxiliary brake so as to brake the combustion engine, if not already activated.

Abstract: A control device and method for controlling a compression release brake arrangement is provided. The compression release brake arrangement comprises an exhaust valve actuator assembly, a first actuator valve and a second actuator valve. The method comprises controlling the first and second actuator valves to a first state in which one of the actuator valves is open and the other one is closed. The disclosure further relates to a computer program, a computer readable medium, as well as to a vehicle comprising the control device.

Abstract: A valve drive comprising a camshaft with base shaft, a lobe pack mounted on the base shaft and comprising three cam lobes. Two actuator bodies are associated with two actuator pins each connected to a valve of a cylinder of the engine. The lobe pack is axially displaceable along the base shaft so as to for each actuator body change cam lobe aligned therewith. A middle cam lobe has a shape leaving an actuator body aligned therewith uninfluenced thereby. In a first position of the lobe pack a first of the actuator bodies is aligned with and hit and moved by a first cam lobe and the other, second actuator body is aligned with the middle cam lobe, and in a second position the second actuator body is aligned with and hit and moved by a third cam lobe and the first actuator body is aligned with the middle cam lobe.
