An engine wash system includes a manifold for delivering wash liquid to an engine. The manifold includes an internal engine contour segment shaped to correspond with at least a portion of the engine case at the inlet; a wash delivery segment connected to the internal engine contour segment which follows the engine case curvature in an axial direction and hooks around an outside of the engine case at the inlet; an inlet on the wash delivery segment to receive wash fluid; a nozzle on the wash delivery portion directed to spray into the compressor inlet of the engine; and a guide extending from the pipe and shaped to align the manifold with respect to the engine so that the nozzle sprays into the engine aft of the inlet particle separator.

1. An engine wash system with a manifold for delivering wash liquid to an engine with an inlet, case, compressor and inlet particle separator, the manifold comprising: an internal engine contour segment shaped to correspond with at least a portion of the engine case at the inlet to stabilize the manifold in a radial direction;a wash delivery segment connected to the internal engine contour segment, the wash delivery segment comprising a pipe shaped to follow the engine case curvature in an axial direction with a first end portion to hook around an outside of the engine case at the inlet and a second end portion to sit inside the engine case;an inlet on the wash delivery segment to receive wash fluid;a nozzle on the second end portion of the wash delivery segment directed to spray into a compressor inlet of the engine when the first end is hooked around the outside of the engine; anda guide extending from the pipe and shaped to align the manifold with respect to the engine so that the nozzle sprays into the engine aft of the inlet particle separator. 2. The engine wash system of claim 1, wherein the guide connects radially to the pipe at a location spaced from the first end and bends toward the first end to sit between two inlet guide vanes of the engine when the engine wash system is installed. 3. The engine wash system of claim 1, wherein the manifold is coated with a polymeric coating. 4. The engine wash system of claim 1, wherein the pipe is configured to provide a fluid transport path past the guide such that the nozzle is configured to spray the fluid directly into the compressor of the engine when the engine wash system is installed. 5. The engine wash system of claim 1, and further comprising: a strap to connect to the first end portion of the wash delivery segment and to an external engine component. 6. The engine wash system of claim 1, and further comprising: a wash unit to deliver the wash fluid to the manifold inlet. 7. The engine wash system of claim 1, and further comprising: a collector for collecting wash liquid from an engine washing operation. 8. The engine wash system of claim 7, wherein the collector comprises: a collection pan with a base and extendable sides, wherein at least a portion of the base is angled toward an outlet;a plurality of wheels connecting to the base;a first vertically extending collection apparatus connecting to the collection pan; anda second vertically extending collection apparatus connecting to the collection pan. 9. The engine wash system of claim 8, wherein the first vertically extending collection apparatus comprises: a first support connecting on a lower end to the collection pan and extending vertically upward from the collection pan,a first funnel connecting to the first support,a first hose connecting the first funnel to the collection pan; andwherein the second vertically extending collection apparatus comprises: a second support connecting on a lower end to the collection pan and extending vertically upward from the collection pan,a second funnel connecting to the second support, wherein the second funnel is positioned at a location spaced from the first funnel, anda second hose connecting the second funnel to the collection pan. 10. The engine wash system of claim 9, wherein the first support, the first funnel, the first hose, the second support, the second funnel and the second hose are configured to be disconnectable from the collection pan, and are further configured to permit selective placement inside the collection pan, and wherein the first and second sides are configured to permit rotation to cover the collection pan with the first support, the first funnel, the first hose, the second support, the second funnel and the second hose inside. 11. The engine wash system of claim 8, wherein the collector further comprises: a tow bar for moving the collector. 12. The engine wash system of claim 8, wherein the extendable sides each comprise: first and second rotatable panels connected to first and second sides of the collection pan. 13. The engine wash system of claim 1, wherein the internal engine contour segment is configured in a W shape. 14. The engine wash system of claim 13, wherein the pipe of the wash delivery segment is connected to a central portion of the internal engine contour segment in a substantially perpendicular relationship. 15. The engine wash system of claim 1, wherein the internal engine contour segment is configured to be selectively engaged with a crescent shaped inner case surface. 16. A method of washing an engine with a case, a compressor with an inlet, a plurality of inlet guide vanes and an inlet particle separator, the method comprising: securing a manifold with a nozzle to the engine by inserting an internal engine contour segment of the manifold into an inlet of the engine case so that a first end of a wash delivery segment wraps around to an outside of the engine case and a second end of the wash delivery segment of the manifold extends axially into the engine and a guide rests between two inlet guide vanes;delivering wash fluid to an inlet on the manifold;flowing the wash fluid through the wash delivery segment to a nozzle on the second end; anddirecting the wash fluid through the nozzle at the compressor inlet. 17. The method of claim 16, wherein the step of securing a manifold to an engine comprises: securing the manifold to the engine so that the nozzle on the second end is located axially aft of the inlet particle separator. 18. The method of claim 16, wherein the step of securing a manifold to an engine further comprises: connecting a strap between the wash delivery segment and another aircraft component. 19. The method of claim 16, and further comprising: collecting the used wash liquid exiting the engine, wherein the step of collecting the used wash liquid exiting the engine comprises collecting wash liquid from engine exhaust with a collection pan with rotatable side panels and collecting wash liquid from engine cases with funnels connected to the connection pan by adjustable supports and hoses. 20. The method of claim 16, and further comprising: collecting the used wash liquid exiting the engine;treating the collected wash liquid; anddelivering the treated wash liquid back to the manifold inlet to be used for washing.
