at lower RPM. Centrifugal superchargers, which become more efficient as the impeller spins faster, provide more power at higher RPM. Installing a turbocharger requires extensive modification of the exhaust system, but superchargers can be bolted to the top or side of the engine. That makes them cheaper to install and easier to service and maintain. Finally, no special shutdown procedure is required with superchargers. Because they are not lubricated by engine oil, they can be shut down normally. Turbochargers must idle for about 30 seconds or so prior to shutdown so the lubricating oil has a chance to cool down. With that said, a good warm-up is important for superchargers, as they work most efficiently at normal operating temperatures. Superchargers are common additions to the internal combustion engines of airplanes. This makes sense when
The crankshaft is semi-built, i.e. the parts are either shrunk or welded. The crankshaft consists of a number of cranks or throws, which are rotated by piston forces transmitted through the connecting rods and bottom end bearings. Every crank is made up of two webs joined by a common crankpin to which the bottom end bearing is fitted. Each web is also connected to a journal to form part of a continuous shaft. A main bearing will support the shaft at each journal. The main bearings are lubricated via a main lubricating oil pipe that branches off to the individual bearings, whereas oil for lubricating the crankpin bearings is supplied from the crossheads through bores in the connecting rods. At the aftmost end of the crankshaft a turning wheel is fitted. Furthermore, the crankshaft is provided with a thrust collar, on which a chain wheel for the camshaft drive is fitted. The thrust bearing serves the purpose of transmitting the axial thrust of the

The timing chain and sprockets are lubricated by an oil four cylinder, in-line OHV construction, but ejection nozzle. nearly every aspect of the engine has been re- 2A OHV engines designed.
