This patented and unique engine features transparent engine construction, which exposes all the moving parts of a 4-cycle engine. Since the is oil-less too, it enables the students to observe clearly the crankcase components and internal combustion of the engine. The Oil Less Four Cycle Multi Fuel Engine Performance program has made the study of 4-cycle engines a simple task and opened the door for the student to conduct multiple experiments in alternate fuels. Includes variable timing and compression.

The Piping Loss Apparatus Large is intended to be used with a Hydraulic Bench or an outside water supply. Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Piping Loss Apparatus Large is a comprehensive unit for studying the friction losses in pipes, pipe fittings, and valves and to determine coefficients of discharge for primary flow measuring devices at various flow rates. All friction loss components and the flow measuring devices are arranged on a water proof panel which is attached to a floor standing steel frame. Flow rate is obtained from a water meter and a stop watch. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses. The pressure drop is measured by differential pressure using manometers. Pressure tapping in by valves with quick connection.

The installation of a gearshift rod with abutton and a mechanical clamping lever means that all the gears can be shiftedand the function of the hydraulic controls demonstrated. The automated, sequential six-gear transmission developedfrom the classical six-gear manual transmission is controlled by the enginemanagement. With the help of a hydraulic piston, 2 gears can be shifted on eachshift level. In this way, the old gear is firstly removed and then the selector shaft turnedonto a different shift level by a pin in the arrested gate sleeve when theinlet selector shaft is displaced by the first hydraulic piston. To change to another shift level, a gate sleeve, which had beenable to rotate loosely up to then, is arrested by a second hydraulic piston. Now, shiftinginto the next gear is possible.
