This engine ran @2000rpm for
sustained periods of time from a compressed Argon source. Throttle response was instant, predictable and consistent throughout the whole throttle range.
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 through the injector assembly itself. The pressure source has full flow to the injector assembly. A throttle valve is not needed with this system, since the injector regulates flow through variable valve lift.
It is important to note that the
L912 Injector 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.
With 12vdc actuation, the spring is compressed to
30 lbs or more at rest and has a full 1/8 inch in travel compression. Stronger spring rates allow for higher operating speeds. This
is the standard specification for current injectors and it allows for engine
speeds at or above 2000rpm. Lift is fully adjustable while
cycling from 1/8 inch to 0.0 inches through the variable valve lift
feature.
The L912 Injector is easily interfaced with the
engine through an electronic cam sensor.
