L912 Injector

L912 INJECTOR™- direct injection valve used to run flash steam engines.

This engine ran @2000rpm for sustained periods of time with full throttle. Also the engine was throttled down to less than 800rpm. Throttle response was instant, predictable and consistent. With a full tank of argon the run time was eleven minutes at a minimum of 1500rpm. And with varying throttle settings the run time was more than 22 minutes. The average of 1000rpm, with a fresh tank the run time is for 21 minutes.  Thus demonstrating efficient throttling capabilities of the L912™ injector. All engine throttling is accomplished thru the injector assy. The tank is left wide open to the injector at all times the engine is running, idling or not. It is important to note that  L912™technology   can handle more than just steam or hot water. And has solid 316L construction of the pressure body. A Graphite impregnated PTFE seal is the standard for all injectors. At 12vdc actuation, the spring is compressed to 30 lbs at rest. And has a full 1/8in. in travel compression. This is the standard spec for current injectors. And allows for engine speeds at or above 2000rpm. Which is fully adjustable while cycling, from 1/8in. to 0.0in. Thru the variable valve lift feature. Usually "adjustable travel throw" never exceeds the orifice diameter, which is standard at 3/16in. In this particular case the the water cooled solenoid assy is connected to, a self heated 316L high pressure valve. Combined with dynamic variable throw. Creating a super fast- dynamically fully adjustable, bolt on valve gear. That has high temperature operating capabilities. The L912™ Injector is easily interfaced with the engine thru an electronic cam sensor. In fact it takes almost four hours of continuous operation at 30hz, to bring a fully charged battery down to 10 volts. Maintaining full range of throw the entire time. With no charging while operating. This can be demonstrated with a 'healthy" 550 CCA automotive battery. During operation of the cycling, the pulse modulation schedule caused a continuous current draw of about 55amps.
