PRESENTATION OF ENGINE 384 F ( CFA)
Engine : CFA
Con rods and big end bearing shells
(12) gudgeon pin
The forged steel con rods have increased rigidity and reduced weight.
The con rod caps are fixed with extended tension screws (11).
The glide surfaces of the big end bearing shells have micro-grooves "n" for optimal oil release. This
solution results in the engine starting more readily from cold, also reducing vibrations.
Crankshaft and crankshaft bearings
"r" hole for the oil.
(13) upper bearing shells.
(14) lower bearing shells.
The crankshaft possesses 4 journals and 6 counterweights.
All the journal contact surfaces are roll-finished "s" in order to maintain the appropriate rigidity.
The crankshaft bearing shells are in aluminium alloy.
The surfaces of the crankshaft bearing shells have micro-grooves "q" for optimal oil release. This
solution results in the engine starting more readily from cold.
The upper bearing shells have an oil groove "p" on the inner circumference
