METHOD FOR SUPPLYING VAPOUR TO THE INTAKE AIR OF AN INTERNAL COMBUSTION ENGINE, AND DEVICE THEREFOR

摘要

The invention relates to a method for supplying vapour to intake air that is supplied to an internal combustion engine (1). The method comprises the steps of compressing the intake air before supplying the vapour and contacting, in a moistening means (8), the intake air with liquid, by simultaneously feeding the compressed intake air and the liquid into the moistening means (8) and causing the intake air and the liquid to flow in opposite directions through the moistening means (8). The invention also relates to a device for supplying vapour to the intake air of an internal combustion engine (1), to which a compressor (6) for compressing the intake air is connected. The device comprises a moistening means (8), which is connected between the compressor (6) and the engine (1) and which comprises a first connection for feeding the water into the moistening means (8) and a second connection for feeding the intake air into the moistening means (8), the moistening means (8) being adapted to carry out the supply of water vapour to the intake air by contacting the intake air and the water with each other, while flowing in opposite directions through the moistening means.
