Fluid then passes through outlet ltitl of fluid or hydraulic motor 91 through a line 101 to hydraulic fluid storage tank 21. An outlet line 102 extends to a filter generally indicated at 103, from which a line 104 extends back to pump 95,
A suitable fill pipe 1% provided with a closure cap 106 permits the refilling of gasoline tank 210.
Control valve 97 may be of any desired conventional type for the control of hydraulic fluid under high pressure from pump 5.
Referring now to filter 163, it is pointed out that the filter is especially designed for use with hydraulic fluid, such as oil or other liquids propelled under high pressure utilizing a minimum of space, for transmission in a minimum time.

Engines of from 300 to 600 cubic inches take two quarts, and over 600 cubic inches, three quarts. The container is divided into sections to enable the operator to apply cleaner to a large engine using three quarts in approximately the same time that would be required for a smaller engine.
Any desired engine cleaning fluid may be used, but applicant has found that a cleaning fluid comprised of the following ingredients is exceptionally satisfactory for the purpose.
Deodorized kerosene Tri cresyl phosphate Chloroform Carbon tetra-chloride Acetone Isopropyl alcohol Coloring (trace) From the foregoing the use and operation of the device should now be readily understandable. When employing the instant invention in conjunction with diesel truck engines, the following procedure should be employed. The engine of the vehicle is first started and run until normal operating temperature is reached. The
The compression release is then pulled and locked. It is to be noted that an engine not having a compression release two complete turns on the adjusting screws on intake valves will relieve compression. It may be pointed out that the cleaner should never be applied to a diesel engine without first relieving the compression as serious damage can be done by the engine starting and overspeeding.
The next step in the operation is to remove the air intake from the top of the intake manifold and with the transmission in direct drive and the truck clutch engaged, start rotation of the driving roller 88 by means of actuation of the engine 41 in the manner previously described. The engine cleaning material is then metered into the intake manifold while cranking the engine. After the application of cleaner is completed the engine should be cranked for an additional fifteen minutes or more to complete the cleaning action and to eliminate all fumes of the cleaner from the engine and then stop.
When the air intake is reconnected to the intake manifold, and the compression adjustments are reset, the engine may be started normally and is now ready for use. The procedure is substantially identical for gasoline truck engines except that the compression is not released.
Under conditions where it is desired to clean stationary power plants, marine and aircraft engines and engines in cars or trucks with automatic transmission where the engine cannot be turned over by applying power to the rear wheels, hydraulic motor 91 must be connected to the engine being cleaned by other means. FIGURES 13, 14, and 15 disclose an adapter which may be employed for this purpose. This adapter is generally indicated at 135 and comprises a U-shaped member having a bight 136 and oppositely disposed legs 137 and 138. A hinged connection 139 engages a suitable lug on motor 91, and an arm 140 extends at an angle from leg 138. A pair of clamping bolts 141 provided with flat clamping heads 142 extend through suitable openings in leg 138, and are adapted to be clamped to the frame F of an engine E to be cleaned, by rotation of handle members 143. An apertured lug 144 extends from the opposite side of motor 91 and is engaged by the end 145 of a belt tensioning bolt 146 which extends through a suitable opening in arm 140 and through a clamping nut 147. Bolt 146 is also provided with a rotatable handle 148. When it is desired to attach motor 91 directly to the fly wheel pulley P of a stationary engine, or other engine which is not associated with a wheeled vehicle, the U-shaped bracket is clamped to frame member F in such position that the pulley P is aligned with the pulley 91a of hydraulic motor 91. A V-belt 150 is then expected about the two pulleys, and the tension suitably adjusted by a rotating handle 148 which, through bolt 146, rotates the motor 91 about hinge 139. The appropriate hose connections are then made to the inlet 99 and outlet of pump 91 and the device is ready for operation.
When employing the adapter unit of FIGURES 13, 14, and 15, the procedure is to start the engine of a diesel type engine and run until normal operating temperature is reached. The fan and generator belts are then removed, and the bracket is attached to engine frame F, and the driving belt 150 connected between pulley 91a and pulley P. The transmission or clutch is then positioned in neutral position, and the compression release is pulled and locked. After this the operation is identical to that previously described in connection with diesel truck engines.
When handling auxiliary gasoline engines the procedure is identcal except that the compression is not released.
Now from the foregoing it will be seen that there is herein provided an improved auxiliary cranking unit which is readily adaptable to any type of internal combustion engine, either diesel or gasoline, and either in association with a motor vehicle, or stationary, or with marine or aircraft engines, which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
I claim:
An internal combustion engine cleaning apparatus comprising a portable wheeled trailer, including a frame, a gasoline engine on said trailer, a hydraulic pump operable by said gasoline engine, a platform on said trailer adapted to carry a wheel driving unit, a wheel driving unit, means for connecting said wheel driving unit when removed from said platform to an engine to be cleaned, said wheel driving unit comprising a frame, a drive roller rotatably mounted in said frame, a parallel roller rotatably mounted in said frame, a hydraulic motor adapted to be connected to said drive roller, a hydraulic fluid reservoir on said trailer, elongated flexible tubing connecting said hydraulic pump to said hydraulic motor, additional elongated tubing connecting said motor to said reservoir and further flexible tubing connecting said reservoir to said pump, and a rotatable crane carried by said trailer for lifting said wheel driving unit on and ofl said platform.
