The invention claimed is: 1. A system for collecting and treating waste liquid from engine washing comprising: a collecting device for collecting waste liquid during a washing operation of an engine, said collecting device comprising a plurality of components, all of which are free of any physical connection to any portion of said engine during the washing operation, including, a liquid separator positioned at a distance from an outlet of said engine, said liquid separator being configured to receive washing liquid entrained in an air stream exiting said engine outlet and to separate said washing liquid from said air stream; and a liquid collector arranged to collect separated liquid from said liquid separator and liquid exiting the engine resulting from the washing operation; and a treatment device for treating waste liquid collected during said washing operation, said treatment device including a filter arranged to remove particles and ions from said liquid; said treatment device being connected to said liquid collecting device such that waste liquid is directed from said liquid collector to said treatment device for treatment in said filter. 2. The system according to claim 1, wherein said collecting device further comprises: a liquid storing component arranged to collect and store separated liquid from said liquid separator and liquid exiting the engine resulting from the washing operation collected by said liquid collector. 3. The system according to claim 2, wherein said liquid collector comprises: a funnel element arranged to collect separated liquid from said liquid separator; and a guide element arranged to be located below said engine during said washing operation in order to collect and guide liquid exiting from said engine to said funnel element. 4. The system according to claim 3, wherein said funnel element is a trough arranged to direct liquid entering an inlet opening to said liquid storing component. 5. The system according to claim 3, wherein said funnel element is directly connected to said pump. 6. The system according to claim 3, wherein said guide element is a chute having a front end and a rear end, said front end being arranged vertically higher than said rear end, said rear end being arranged at said funnel element so that liquid collected by said chute is directed to said funnel element. 7. The system according to claim 1, wherein said treatment device further includes a liquid storing component arranged to collect and store liquid treated by said filter. 8. The system according to claim 1 wherein said liquid separator includes separator profiles arranged to deflect the air stream in order to separate the droplets of the waste liquid from the air stream. 9. The system according to claim 8, wherein said liquid separator profiles are arranged to guide said liquid to an opening in a face directed against said liquid collector. 10. The system according to claim 1, wherein said filter comprises: a first filter arranged to remove particles from said liquid; and a second filter arranged to remove ions from said liquid. 11. The system according to claim 10, wherein said first filter is a sediment type filter. 12. The system according to claim 10, wherein said second filter is a metal particulate bed type filter. 13. The system according to claim 1, wherein said treatment device further comprises a pump arranged to pump liquid from said liquid storing component or from said liquid collector to said filter. 14. The system according to claim 1, further comprising a mobile cart with a wheeled chassis for serving an engine during a washing operation of said engine, said system arranged on said chassis, and an adjusting device for adjusting a position of at least one of said liquid separator, said liquid collector, and said liquid storing component relative to said engine. 15. The system according to claim 14, wherein said adjusting device is configured to adjust said position in at least one of a vertical, horizontal, or lateral direction. 16. The system according to claim 14, wherein said liquid separator is arranged on supports arranged on said chassis and said adjusting device is one of a hydraulic, pneumatic and chain driven unit. 17. The system according to claim 14, wherein said adjusting device is a scissor lift arranged on said chassis. 18. A collecting device for use with multiple engine types and sizes of engines for collecting waste liquid from washing of an engine while the engine is being cranked, wherein cranking of the engine creates an air stream through the engine, thereby entraining the washing liquid into the air stream, and with the air stream having a velocity that ranges anywhere between low to high velocities according to the engine type and size of the engine, the collecting device comprising: a liquid separator positioned at a spaced separation from an outlet of said engine, said liquid separator being configured to receive washing liquid entrained in an air stream exiting said engine outlet and to separate said washing liquid from said air stream; and a liquid collector positioned at a spaced separation from the engine and to collect separated liquid from said liquid separator and liquid exiting the engine resulting from the washing operation, wherein both said liquid separator and said liquid collector are free of physical connection to any portion of the engine during a waste liquid collection operation, whereby said liquid separator and said liquid collector are operable to accommodate multiple engine types and sizes of engines, and a range of air stream velocities generated as the engine is being cranked depending on the engine type and size of engine, including low velocities, high velocities and all velocities between low and high velocities. 19. The collecting device according to claim 18, further comprising: a liquid storing component arranged to collect and store separated liquid from said liquid separator and liquid exiting the engine resulting from the washing operation collected by said liquid collector, said liquid separator, said liquid collector and said liquid storing component each being free of any physical connection to said engine. 20. The collecting device according to claim 18, wherein said liquid separator includes separator profiles arranged to deflect the air stream in order to separate the droplets of the waste liquid from the air stream. 21. The collecting device according to claim 20, wherein said liquid separator profiles are arranged to guide said liquid to an opening in a face directed against said liquid collector. 22. The collecting device according to claim 18, wherein said liquid collector comprises: a funnel element arranged to collect separated liquid from said liquid separator; and a guide element arranged to be located below said engine during said washing operation in order to collect and guide liquid exiting from said engine to said funnel element, said funnel and guide elements each being free of any physical connection to said engine. 23. The collecting device according to claim 22, wherein said funnel element is a trough arranged to direct liquid entering a inlet opening to said storing component. 24. The collecting device according to claim 22, wherein said guide element is a chute having a front end and a rear end, said front end being arranged vertically higher than said rear end, wherein said rear end is arranged at said funnel element so that liquid collected by said chute is directed to said funnel element. 25. The collecting device according to claim 18, further comprising an adjusting device for adjusting a position of at least one of said liquid separator and said liquid collector relative to said engine in order to accommodate multiple engine types and sizes of engines. 26. The collecting device according to claim 25, wherein said adjusting device is configured to adjust said position in at least one of a vertical, horizontal, and lateral direction. 27.
