A control valve and an air starting system for an engine having a pressurized air source, an air starter, and a control valve. The control valve having a housing defining a flow passage with an inlet port fluidly coupled to the pressurized air source and an outlet port fluidly coupled to the air starter, a valve body movable between an opened and closed positions to selectively open and close one of the inlet and outlet ports, resulting in a corresponding opening and closing of the control valve, and a linear motor operably coupled to the valve body to move the valve body between the opened and closed positions.

Disclosed is a combustion engine and method for engine braking therein including an intake air channel having a first pressure, a first inlet valve between the intake air channel and the cylinder volume, an exhaust air channel having a second pressure, a first outlet valve between the cylinder volume and the exhaust air channel, and a storage reservoir having a third pressure higher than the first and second pressures, the storage reservoir being arranged in controllable fluid communication with the cylinder volume. The method takes place during two-stroke cycle and includes: displacing the piston from upper dead center (UDC) towards lower dead center (LDC), keeping the first inlet valve open during at least part of the travel from UDC to LDC, displacing the piston from LDC towards UDC, and keeping the fluid communication between the storage reservoir and cylinder volume open during at least a part of such travel.
