REGI US Inc. and REG Technologies Inc. announced that successful tests were completed for the RadMaxTM engine. The engine was assembled with half of the vanes and cam followers installed, one set of vanes were positioned to allow the installation of all seals and form a single combustion chamber. A hydrostatic pressure test was performed first at 400 psi, then 800 psi, and 1,000 psi, Main bearing function test was performed. Engine binding and alignment tests were performed. Additional friction data was obtained. A single combustion chamber was tested to verify pressure containment. The friction with the current arrangement was measured at about 200 ft. lbs.

On 03/19/2013, REGI US Inc. announced that they will be unable to file their next 10-Q by the deadline required by the SEC.

REG Technologies Inc. and REGI US Inc. announced that the assembly on one side of the RadMaxTM engine is completed and initial tests have commenced. To date, friction testing has been initiated with positive results. The initial dry friction tests indicate the engine should have friction loads equal to or better than a standard diesel engine. After the completion of the friction and compression tests the entire engine will be assembled and tested with diesel followed by compressed natural gas. Assembly and Testing of the Diesel Prototype is the focus of efforts at Williams and White. All parts are complete. Most Subassemblies are complete. The rotor and driveshaft were successfully assembled. Two slots and oil coolers were corrected. A single side of the engine was assembled with two vanes and actuators placed in adjacent slots. Dry friction numbers were obtained for the installed vanes and actuators. Dry friction of the rotor, shaft and cam alone is virtually zero. The force of gravity alone would rotate the assembly to where the oil coolers were installed. Dry friction was measured with two actuators installed with vanes, but no seals. The vanes were placed in adjacent slots with the oil coolers minus the seals and the linear bearing installed. Observed: Static friction was measured at 72 ft-lbs at the rate of 1 rpm. Alignment of the stator to cam was critical to the value of the friction measured. There was zero lubrication of the bearings, oil cooler and vanes. Evidence of rubbing of the vane against the oil coolers was observed at disassembly.
