32-504: A single unit . The new engine featured a recirculating wet sump oiling system at a time when most motorcycle manufacturers used a total-loss oiling system . BMW used this type of recirculating oiling system until 1969. To counter the cooling problems encountered with the Helios, Friz oriented the R32's M2B33 boxer engine with the cylinder heads projecting out on each side for cooling, as used in

48-407: A 3 to 10 litres (0.66 to 2.20  imp gal ; 0.79 to 2.64  US gal ) capacity pan at the base of the engine, known as the sump or oil pan, where it is pumped back up to the bearings by the internal oil pump . A wet sump offers the advantage of a simple design, using a single pump and no external reservoir. Since the sump is internal, there is no need for hoses or tubes connecting

64-496: A long-term solution of an all new motorcycle design. This new design was designated the BMW R32 and began production in 1923, becoming the first motorcycle to be badged as a BMW. The M2B33 engine in the R32 had a displacement of 494 cc and had a cast-iron sidevalve cylinder/head unit. The engine produced 8.5 hp (6.3 kW), which propelled the R32 to a top speed of 95 km/h (59 mph). The engine and gear box formed

80-514: A motorcycle this difficulty does not arise, as a bike leans into corners and the oil is not displaced sideways. Nevertheless, racing motorcycles usually benefit from dry sump lubrication, as the shallow sump allows the engine to be mounted lower in the frame; and a remote oil tank can allow for improved lubricant cooling. On some dry sump motorcycles, such as the Yamaha TRX850 and the Yamaha TDM ,

112-410: Is used as an integral oil reservoir. An alternative system is the dry sump , whereby oil is pumped from a shallow sump into an external reservoir. Piston engines are lubricated by oil which is pumped into various bearings , and thereafter allowed to drain to the base of the engine under gravity. In most production automobiles and motorcycles , which use a wet sump system, the oil is collected in

128-463: The fuel/air mixture through the crankcase. This precludes the use of both wet sump and dry sump systems, as excess oil here would contaminate the mixture, leading to excess oil being burned in the engine and so excessive hydrocarbon emissions . These small engines run on specifically prepared fuel, a mixture of gasoline and two-stroke oil in a ratio recommended by the manufacturer. In some engines this mixture may also be independently pre-injected into

144-476: The Helios motorcycle. Upon completing his assessment, Friz suggested to Popp that the best thing that could be done with the Helios would be to dump it in the nearest lake. More specifically, Friz condemned the Douglas -style transverse-crankshaft layout, which heavily restricted the cooling of the rear cylinder. Popp and Friz then agreed to a near-term solution of redesigning the Helios to make it more saleable and

160-461: The boxer-twin, shaft-drive powertrain layout that BMW would use until the present. BMW used shaft drives in all of its motorcycles until the introduction of the F650 in 1994 and continues to use it on their boxer-twin motorcycles. Ref: Any picture of the bike shows the trailing links. Wet sump Within piston engines , a wet sump is part of a lubrication system whereby the crankcase sump

176-474: The earlier British-manufactured ABC . Unlike the ABC, however, the R32 used shaft final drive from a flexible coupling on the gearbox output shaft to a pinion driving a ring gear on the rear wheel hub. The R32 had a tubular steel frame with twin downtubes that continued under the engine to the rear wheel. The front fork had a trailing link design suspended by a leaf spring, similar to the forks used by Indian at

192-418: The engine to an external sump which may leak. An internal oil pump is generally more difficult to replace, but that is dependent on the engine design. A wet sump design can be problematic in a racing car, as the large g force pulled by drivers going around corners causes the oil in the pan to slosh, gravitating away from the oil pick-up, briefly starving the system of oil and damaging the engine. However, on

The engine

224-550: The oil tank is integral to the engine, sitting atop the gearbox. Early stationary engines employed a small scoop on the extremity of the crankshaft or connecting rod to assist with the lubrication of the cylinder walls by means of a splashing action. Modern small engines, such as those used in lawnmowers, use a "slinger" (basically a paddle wheel) to perform the same function. Small two-stroke engines , such as in motorcycles and lawnmowers , have total loss lubrication. Such engines use crankcase compression to feed

240-423: The time. The rear wheel was rigidly mounted. In the original First Series, braking was accomplished solely with a "dummy rim" on the rear wheel with two padded brake shoes set within it. One would be operated by the, now traditional, right hand lever and the other by use of a heel actuated lever on the right side. Later years would reroute the front right lever and cable to a front drum brake. The R32 established

256-559: Was initially intended as a portable industrial engine, but found its main use in Victoria motorcycles. The engine was also used in the Helios motorcycle built by Bayerische Flugzeugwerke, which was later merged into BMW AG. Bayerische Flugzeugwerke also manufactured a small two-stroke engined motorcycle, called the Flink, which was not successful. After the merger, General Director of BMW Franz Josef Popp asked Design Director Max Friz to assess
