Another early problem of buildup of cracks in the stator surface was eliminated by installing the spark plugs in a separate metal piece instead of screwing it directly into the block .. A later alternative solution to spark plug boss cooling was provided by variable coolant velocity scheme for water-cooled rotaries which has had widespread use and was patented by Curtiss-Wright, with the last-listed for better air-cooled engine spark plug boss cooling.

It used an 816 cc flat twin water-cooled engine of 6. 4 hp and three-speed gearbox with tiller steering.

C. M. Manly constructed a water-cooled five-cylinder radial engine in 1901, a conversion of one of Stephen Balzer's rotary engines, for Langley's Aerodrome aircraft.

Little development of the radial engine was undertaken in Germany during World War I, where most aircraft used water-cooled inline 6-cylinder engines.

By 1918, the potential advantages of air-cooled radials over the water-cooled inline engine and air-cooled rotary engine that had powered World War I aircraft were appreciated but remained unrealized.

March 1936 saw an update to a twin cylinder water-cooled J. A. P.

The final cars from 1923 were the " Twin-Cars " which were effectively two sidecars side by side with the driver in the off-side one and powered by a choice of air-or water-cooled 9-horsepower 1078 cc V twin cylinder Anzani engines with chain drive mounted between the two passenger units.

Due to the head gasket failures of the 1977 biturbo, Porsche parted with their air cooling tradition and introduced water-cooled cylinder heads in the 1978 engine, and equipped them with four valves, too.

In spite of its 911 moniker the car actually had very little in common with the 911 of the time, however its frontal chassis was shared with the then ( 993 ) 911, while the rear of the car was derived from the Porsche 962, including its water-cooled, twin-turbocharged and intercooled, four valve per cylinder flat-six engine which was arranged in a mid-mounted position, compared to the rear-engined layout of a conventional 911.

1916 Benz Bz. IV 19-liter water-cooled straight-6 aircraft engine with aluminium pistons, dual camshaft and four valves per cylinder achieved 230 bhp / 170 kW @ 1, 400 rpm ( 9. 0 kW / liter ).

Not only was the 500 cc engine water-cooled, but it had four valves per cylinder that were operated by pushrods rather than the overhead cams favored by Honda on its previous four-stroke engine designs.

The CX500TC powerplant was based on the water-cooled V-twin / four pushrod-operated overhead valves per cylinder configuration used in the CX500 introduced a few years earlier — itself a groundbreaking design.

It is powered by the marine version of Traxxas ' Pro. 15 nitro engine, which features a water-cooled head instead of the land version's air-cooled head.

While fins are absolutely necessary on an air-cooled engine — they increase the surface area of the head, hence improve cooling — they serve no function on a water-cooled engine.

Early heavy machine guns were often water-cooled ; while very effective, the water also added considerable weight to an already bulky design.

The Audi 100 would be a commercial success, but it would also be the first of a series of front-engined water-cooled Audi based designs from the Volkswagen group that would, starting with the first Passat in 1973, enable the group to survive and flourish once the European and US markets began to lose their appetites for rear-engined air-cooled models.

As Volkswagen started to produce front-wheel-drive water-cooled designs, production ended in 1973 at the Wolfsburg plant, with production moving to VW's new Emden plant, which was later retooled in 1973 to build the first generation Passat ( marketed variously, also as the " Dasher ").

In far Russian east the Tatra Trucks are used by oil and gas companies in the most difficult terrains, where also the air-cooled engine proves its superiority over water-cooled during harsh winter time.

The team also developed a 52 bhp water-cooled 500 cc version, but competition from Japanese two-strokes meant that the project was not fully developed.

The engine was the 1, 628 cc four-cylinder water-cooled unit which by now powered the 7C version of the manufacturer's Traction passenger car, which also provided the van's three-speed manual transmission and front torsion-bar suspension and ( still innovative ) front-wheel drive drive-train.
