Variable timing

Postby Remps » Tue Jul 30, 2013 2:57 pm I found the part about the effects of variable timing on cylinder pressure with these 2 stroke injection pumps interesting. Injection timing doesn't advance till 40% load, then starts retarding at 85% load to level out combustion pressure at 85% to 100% load. So for the helluvit I posted it here.
