MP Jets Diesel Hybrid, hot starts

Tags: , , , ,

This clip illustrates that it’s the HEAT that allows a diesel engine to run on a no ether fuel . With the magic castor and Amsoil mix, sufficient heat is generated on a few prime runs to allow a start. With the motor oil and MEKP though, it’s a no go. I suspect, however, that though both fuels take the engine up to the same temperature, it’s the castor/Amsoil mix that allows a run at a slightly lower temperature. I did need to overcompress, a small amount, even for a hot start. However, note the no prime start just after shutdown and before the engine cools off . This was with the compression at the final run position. Once again, IT’S THE HEAT that lets our diesel engines run on compression ignition alone.

Aero-TV Gets Reved Up Over The rotamax Rotary Powerplant

Rotary Motivations: The rotamax Powerplant Program In the midst of all the amazing things that comprise the annal Oshkosh Fly-In, Aero-TV took some time out at the 2008 rendition to talk with Eric Barger, president of rotamax Rotary Engines. This company is introducing a line of aviation rotaries based on a long-established, non-automotive design. The company recently signed a tentative OEM agreement to furnish a twin-rotor powerplant for an upcoming light-sport aircraft. The rotamax engine is a Wankel-type rotary engine, named after the German inventor Felix Wankel. Instead of conventional pistons reciprocating inside cylinders with a complex valvetrain, the Wankel has a rotor shaped roughly like a triangle that runs inside a housing with an epitrochoidal cavity shaped roughly like a figure 8. The rotor is geared in relation to an eccentric shaft, which is the equivalent to the crankshaft inside a piston engine. The rotor covers and uncovers ports as it rotates inside the housing, enabling four-stroke Otto-cycle operation without valves. The rotor uses seals as the equivalent of piston rings, including apex seals at the points of the rotor and side seals on the sides. rotamax opines that Wankel engines are inherently smoother and easier to balance because of the rotary operation. For the same output as a piston engine, a Wankel will generally be smaller and lighter and will have far fewer parts, particularly moving parts. In certain applications even in the 1970s, for
