The Type B "Modified" Loyal Cycle Engine
What is a "Loyal cycle" engine?
This is a unique engine that runs on an unusual cycle from the 1870’s. Called the Loyal cycle it operates as a 2-stroke engine with exhaust, intake, compression & expansion in one cylinder with no valves & an open crankcase. It differs from a regular 2-stroke in that there is no external "charging or purging" of the cylinder & it’s also somewhat of an Atkinson cycle engine in that its expansion stroke is longer than the intake. It has no gears, cams or pushrods & can run either direction without changing anything. It’s either hit & miss (by ignition) or can be run as a throttler. (Controlled by changing ignition timing, fuel or restricting the exhaust.)
