I am interested to know what OD sizes of fuel lines are used in diesel HPCR systems and gasoline DI systems? For example, on the Ford 2.0L DI gasoline engine, the line from the high-pressure pump to the rail is .25" (6.35mm) OD. For some diesel HPCR systems, I understand that the high pressure...
A magnetic circuit consisting of two horseshoe magnet assemblies are placed opposite each other with water in between them. Each horseshoe magnet is one simple steel bar core and two block magnets attached at each end of the steel bar and facing outwards in the same direction - one magnet is...
How was the lubrication feed done for aircraft radial engine main bearings? For a vee-engine the top main bearing shell has a 180 deg groove which flows oil into (usually) two holes drilled into the crankshaft main journal, and then feed up to the crankpins to lubricate the rod bearings. The...
All of the generators and alternators I know of use copper windings. However, aluminum is used as a conductor in some applications, most notably for high-tension/high-power transmission lines.
Aluminum would be much lower cost than copper for armature windings in a generator because of its...
