L-4 is a V-4, but they use the L to indicate the 90 degree angle. (edit - thanks to rz33v4 for clarifying).Sam916 said:VERY NICE!
I want one.
A stupid question: have we not been expecting a V - four, but instead I'm reading on ducati.com the following thing: L-four cylinder, twin pulse configuration.
Can someone explain what this means?
Thanks for the info.migz123 said:L-4 is a V-4, but they use the L to indicate the position or angle as installed on the frame.
My understanding of Twin Pulse is (please correct me if I'm wrong) that the pistons behave like a V-Twin would except that there are two pistons "pulsing" at once (instead of ONE-at-a-time on the V-Twin) ... this is different from a normal 4 cylinder bike whose pistons pulsate individually.
If the normal 4 cylinder bike's pistons would pulsate as (by piston number) 1-2-3-4-1-2-3-4-1-2-3-4-1-2-3-4 etc... the Twin Pulse 4 cylinder piston's would pulsate as 12-34-12-34-12-34-12-34... the effect is that it distributes the delivery of strength to the wheels in larger intervals of time, which is an advantage in traction over a regular 4 cylinder. ( I could be wrong, but this is my understanding of what twin pulse means).... kind of like an "inverted" ABS.
