Hit Miss Engine

Being auctioned is a neat, well-made & easy to run gas engine. This engine is sand cast from fine-grain ductile iron & has a lot of detail to the castings. It was recently machined using steel, brass, bronze & iron parts & was designed to look & be built like something that could have been made years ago. Its unpainted & has a natural finish thats easy to care for. This is a great engine for someone interested in internal combustion engines but unfamiliar with them. It has an open crank case that visually shows all the mechanics of the engine. It starts easy, runs great & is simple to operate. The only fuel control is a choke & other than moving the ignition timing lever to extreme positions, the engine cant get out of time. The engine starts by hand-spinning the flywheel & it will run in either direction. It has a fairly wide speed range & can idle extremely slow (see video below) or it can rev to over 4,000 rpm. An internal limiter prevents accidentally over-revving the engine. The engine comes assembled & ready to run; all you need is some gasoline & a 6 or 12 volt battery to power the ignition coil. The engine also comes with an owners manual with simple notes about it & how to run it. The engine, fuel tank, wood box & coil weigh about 13-1/2 lbs. The engine can be seen at the address below. It can be picked up if wanted. New Washington, Ohio 44854. The engine comes with a new RMC solid-state ignition buzz coil. This coil can be used on most any engine & was specially made to be UV & water resistant. The coil connects & disconnects quickly & easily from the engine & battery. The engine runs best off regular gasoline & uses a RMC wick-fed Mason jar fuel tank which comes with the engine. (see pics) This is a free-flow tank, there are no check valves, reed valves or anything mechanical that might gum up & cause problems over time. Being wick fed, it improves carburetion of new or old fuel & will even run the engine in colder temperatures, giving a steadier fuel feed to the engine. It can also run on Coleman lantern fuel, or the engine can be hooked up directly to demand regulated gasses such as propane, etc. Without making any modifications to it. The engine comes with a sanded & sealed white pine storage & display box. The box is 9″ x 10-3/4″ & 4-1/8 tall & can safely hold & store the engine & fuel tank. An oil cup lubricates the cylinder & needs periodically refilled. Notes on this are covered in the manual. The wrist pin is a sealed self-lubricated bearing. The engine is machined from the RMC Type E style of castings. The base was specially sand cast without a follow board using RMCs handmade core-less, rotational patterns. The engine itself stands about 8 tall (to the tip of the exhaust pipe) & weighs about 8-1/2 lbs. While the engine being offered is meant to run occasionally for amusement, mostly at idle & low speeds, it has a rare property in that it can be run wide open indefinitely without aided cooling. The temperature recorded at the hottest spot (base of the spark plug) peaks to around 210 deg. F, which was taken in 80 degree ambient temperature. About the Rowland-RL engine cycle design; The Rowland-RL is a unique “free-breathing” engine meaning that the gases are free to do what they want. The engine shown above does not have gears, cams, valves, sleeves or intake & exhaust ports to control its breathing like other engines do & it can constantly self-adjust (self-compensate) & adapt its strokes to its surroundings the temperature, pressure, humidity, etc. & the way its being run changes to ignition timing, fuel, load, etc. This engine runs off a 2-stroke cycle & achieves intake, compression, expansion & exhaust in just one revolution without aided “charging, purging or scavenging” of the cylinder. It has one dedicated power stroke along with another partial power stroke (making it partially double-acting). In conventional engines, work is usually lost during the exhaust & intake strokes because of pumping loses. On a firing cycle in this engine, work is gained during these events. Because of this engines unique internal design, & from some non-positive (negative) displacement on strokes, the Rowland-RL has the ability to run asymmetrically optimized through a wide rpm range with just a simple, unthrottled & fixed single-jet carb, & with a response that is faster than conventional carbureted engines. Speed & power output on this engine are instead controlled simply & efficiently by changing the engines ignition point, which will in turn change its intake stroke, etc, & the cycle will stabilize with the engine at a certain rpm. (read 2nd sentence above, the cycle is not really mechanically constrained to the strokes & is free to float around). Unlike some 2-strokes, this engine runs reliably with a short exhaust pipe (or none at all) & is one of many RMC engines that show common misconceptions in tuned exhaust pipe & expansion chamber theory. The engine uses a standard (non-ported) piston & runs efficiently without complicated variable-valve timing systems, sliding valve ports or computer aided control like seen in todays engines. It is one of the most mechanically-simple engines. The beauty of this engine is in how it operates & itll be interesting to see who uses this design & attaches their name to it with a different looking engine. At slower speeds the engine runs on the RL cycle & as the engines rpm increases it switches over to the Rowland compression cycle; running as hybrids in between. The “RL” gives credit to the people usually associated with that cycles origin. In its most basic form, the Rowland-RL is a completely valve-less, free-flow simplified version of the originals. Fuel injecting the engines work just as well & these along with special carbureted gasoline versions can be built in any size & run reliably & smoothly through a wide rpm range as compression ignition engines. This was one of many developments at Rowland Mfg. The item “Model Hit Miss Gas Engine old vintage antique steam toy looking motor with coil” is in sale since Tuesday, September 15, 2015.

Being auctioned is a nice running non-compression gas engine with a RMC solid-state ignition coil. Non-compression engines have no compression stroke to their engine cycle & instead fire a charge at or under atmospheric pressure. The newly-built model engine that is being offered is cast from fine-grain ductile iron & has a lot of detail to the castings. (see pictures) The castings were hand filed & detailed & were left unpainted with a natural finish that’s easy to care for. This engine has machined steel, brass, bronze & iron parts & was designed to look & be built like something that could have been made years ago. This engine is unique in that it can switch non-compression cycles just by moving the timing lever. It changes from “Intake, Power, Exhaust” to “Intake, Exhaust, Power” & will stay running the whole time. Unlike traditional non-compression cycle engines, this engine can fire at top dead center each revolution. It’s also a Hemi. Something else unique about this engine is that it can switch into a compression cycle engine just by loosening a screw on top the head. Turning the screw the other way will change the engine back to a non-compression cycle; (See video of this engine below). The engine draws vapor from a Mason jar fuel tank & runs on regular gasoline. The only fuel control is a simple choke. There is a ¼-32 thread glass spark plug located on top of the engine (attached to the black wire). The engine speed can be controlled by advancing or retarding the timer lever (located behind the flywheel) & the engine can be run with the ignition timer in any position. The engine runs great; it’s smooth & steady & since it has no compression, it turns over easy & will start with no effort. The engine can either be hand started by spinning the flywheel or spun over by using the starting crank. The engine comes assembled & ready to run; all you need is some gasoline & a 6 or 12 volt battery to power the ignition coil. The engine also comes with an owner’s manual with simple notes about it & how to run it. The engine, fuel tank, wood display box & coil weigh about 21 lbs. The engine can be seen at the address below. It can be picked up if wanted. The engine comes with a new RMC solid-state ignition buzz coil. This coil can be used on most any engine & was specially made to be UV & water resistant. The coil connects & disconnects quickly & easily from the engine & battery.

The engine comes with a sanded & sealed white pine storage & display box. The box is about 10-3/4″ x 10-1/4″ x 4-1/4 tal. L & can safely hold & store the engine & fuel tank. The box is nicely built & sealed with two coats of good polyurethane that will resist any gas or oil spills. An oil cup lubricates the cylinder & the wrist pin is a sealed self-lubricated bearing. The engine is machined from the RMC’Type D’ style of castings. The base & head were sand cast without a follow board using RMC’s handmade core-less patterns. The engine itself stands about 10-1/2 tall & weighs about 14 lbs. This engine uses an RMC designed valve which was developed for the type C 2-stroke engine. It was meant to be used to switch the type C 2-stroke compression engine into a 2-stroke non-compression engine.
