The
Twingle engine is a two-stroke engine, usually of small-capacity and usually
petrol fuelled. It uses two pistons, one of which controls the inlet ports, the other the exhaust ports. These run in two parallel (geometry)
Cylinder (engine) bores but share a single combustion chamber,
spark plug and
cylinder head.
The first Twingle engine was designed by
Alberto Garelli, who patented the design in 1912. His design had a forked
connecting rod with two small-ends and one big-end, and had a engine displacement of 346 cc. Garelli produced some motorcycles with this engine, but was more successful with more conventional designs.
Two versions of the Twingle engine were produced by Austrian
moped manufacturer Puch. The earlier, based on the Garelli design, was produced from
1923. From 1949 this was replaced by a design by
Giovanni Marcellino, with different sized pistons and a more elaborate connecting-rod setup. The Marcellino engine continued in production until
1970. It was complex and expensive to produce compared to a comparable conventional single cylinder engine, and heavier for the same power output. Its only advantages were claimed to be fuel efficiency and the possibility of working with larger capacity, but in this area it competed with
four-stroke engines. (Even so, in early days of uncertain engine reliability, it sometimes won in that respect - see
Trojan (automobile).)
Both the Garelli and Marcellino engines are sometimes described as two-cylinder and sometimes as one-cylinder. Possibly as a result, the Twingle is sometimes confused with the opposed piston two-stroke
diesel engine design, which has two pistons per cylinder at opposite ends of the cylinder, and no cylinder head at all. Like the Twingle, the opposed piston design uses one piston to control the inlet ports and another the exhaust, but there the similarity ends.
It is easy to see how a Twingle engine could be mistaken for a single cylinder engine. It looks, sounds and in most ways performs like one, and has only one spark plug, but in fact the Twingle has two pistons each in its own separate cylinder bore.
In the UK this type of engine is commonly called a split single. (ref. P E Irving, "Two Stroke Power Units" p23)
