December 9th, 2014 06:18 PM #1i know na ang ideal for diesel engines ay undersquare to produce more torque, but i see some oversquare diesel engines as well,may advantage dn ba ito compared sa undersquare diesel engines?

I think you have it backward. Over square has longer stroke than the piston diameter for higher torque due to a longer crank throw but is not suitable for higher sppeds

For starters, here's a good read.

No, oversquare has bigger bore than stroke.
Typically provide for more revs, but other factors affect this, also.

sa tingin ko e depende na iyan sa application. kung sa akin lamang e i would prefer undersquare than over. mas relaxed idrive ang undersquare lalo na sa hill climb with a heavy load.
pero kung need for speed ka e oversquare.
brader JR318, yung UNDERsquare e mas malaki dimension ng stroke kesa cylinder bore (diameter ng piston). ibig sabihin mas malaki ang buwelo ng piston during the power stroke.
kung OVERsquare naman e mas mabilis nyang tapusin ang apat na stroke sa isang cycle ("mas mabilis ang ikot ng makina")
may mga factors pa rin na makakaapekto sa bawat isa. kaso dudugo na ilong ko sa usapang iyon. hanggan jan na lang. hehe
