Embodiment Construction

[0012] figure 1 , reference numeral 1 refers to a diesel engine. An air supply system 2 is provided in connection with the diesel engine. The air supply system comprises a duct arrangement 3 for supplying the engine 1 with air drawn in from the external environment. A compressor unit is connected to the piping unit 3, only the compressor 4 is shown in the figure for simplicity of illustration. The operation of the diesel engine related to the present invention will be described below. Other aspects of the engine, including the components and operation of the engine itself, may be known in the art.

[0013] Cooling engine blocks and other components is well known. According to the invention, heat is transferred from the engine's cooling circuit 5 to the water in the heat exchanger 6, causing the water to evaporate. In the heat exchanger 6, preferably, a pressure corresponding to at most atmospheric pressure can be maintained.

[0014] Therefore, the water required for hum...

Abstract

Arrangement in connection with a diesel engine (1) comprising an air supply system (2) for the diesel engine for supplying suction air to the engine from the environment, the air supply system (2) comprising at least a channel arrangement (3), a compressor (4) and a heat exchanger (12) for suction air and a cooling circuit (5) for the diesel engine, to which circuit at least one heat exchanger is connected. The heat exchanger (6) connected to the cooling circuit (5), which recovers waste heat from the diesel engine is arranged to evaporate water by the heat received from the cooling circuit (5). The invention also relates to a corresponding method.

Description

technical field [0001] The invention relates to a device for connecting a diesel engine according to the preamble of claim 1 and a method for connecting a diesel engine according to the preamble of claim 7 . Background technique [0002] It is well known that the operation of diesel engines produces considerable emissions of nitrogen oxides. There are many methods in the prior art to reduce such emissions, such as selective contact reactive reduction systems, direct injection of water into the combustion chamber, and humidification of intake air with steam or water. All prior art methods require high investment and the technical means are relatively complex. Contents of the invention [0003] It is an object of the present invention to provide a device and a method which minimize the problems of the prior art. In particular, the object of the present invention is to provide a device and a method by means of which nitrogen compounds emitted from diesel engines can be redu...
