Special attention is paid to the relative abundance of land transport in the various localities, and the allocation of localities with the highest number of vehicles. The main method of research is the statistical analysis of the data StatBank Greenland, as well as consideration of the legislation of Denmark and regional regulatory legal acts of Greenland.

The article reveals the problem of throwing engine oil into the ventilation system, describes the structure of the engine ventilation system, gives an analysis of the crankcase space and the crankcase ventilation system an information review of the crankcase space, the device of the engine ventilation system and modern approaches to solving the problem with crankcase ventilation, explains the main problems associated with crankcase ventilation and draws certain conclusions.The approaches to solving this problem are described as complex systems – ventilation with a PCV valve, a reducing valve and an ejection pump, and relatively simple – an iron mesh inside the crankcase intake tube. It has been proposed to divide the entire volume of the crankcase space into two main volumes to ensure efficient operation of the ventilation system: the lower and the upper.
