Talk:BMW 801

From Wikipedia, the free encyclopedia

BMW 801 TJ saw a short production run, as it equipped about 100 Ju-388; I'm not sure about the high altitude ratings for this engine, can anyone give a good source for them?

This source [1] claims that the 801 had only a single intake AND exhaust valve. Looking at the engine and seeing only two pushrods, this doesn't seem so crazy. Any other sources on this? Maury 22:29, 8 November 2005 (UTC)

Every other source that I can find agrees. Changing. Maury 22:37, 8 November 2005 (UTC)

[edit] Valves and pushrods

The cylinder heads used one inlet and one exhaust valve with matching pushrods. the cam ring had two rings with four pairs of lobes 90 degrees apart. the cam ring rotated at one eight crankshaft speed. the pushrods were set up so that one cam ring was for exhaust and the other was for the inlet valves. Each pushrod was operated by a roller folloewr. The angle between the pushrods set the timing for the valves operation with the eshust operating first and then the inlet. This design of the cam ring made the grinding of the lobes a simple process. By Mike Nixon @ Vintage V-12's75.38.66.114 03:17, 17 December 2006 (UTC)
