Coul I connect two or three 100 cc motors (for more power and low fuel cost)together to replace the motor in my car?

There isnt enought time it happens in mil sec of coures if the piston stays down.

severng as the piston moves down under compression the exhast opens first at this point the gases start rushing out to atmosphic presure this allow about 85% of gases to excape now for the magic the fresh charge under the piston under presure forces a remaining 12% out leaving 3% in but allows some of the fresh charge out these relationships are refered to as savaging.

well you gutta love those imports then if you live there

Well, that depends very much on the boat hehe. I think the torque on a 4 stroke 250 would be stronger then a 150 two stroke on a 36 feet boat. :-)
But then again, it is also alot about the direct injection, do they have carburetor, or EFI (Electronic fuel injection) or other direct injections... I think at two stroke it is essential that direct injection is used.

not saying they are but compare a 125 two stroke to a 250 4 stroke. theyre pretty evenly matched.

Some of the fuel mixture does get blown out the exhaust port....
Hence why 2 Strokes are unefficient creatures to run and one of the reasons they are not produced for the UK market anymore.
Global Warming and all that BS....
Bring back the 2 stroke I say... woohoo

one thing i dont get though is the exhaust port doesn't get shut off in any way, so how come the fuel/air/oil mixture doesn't get pushed straight out of the exhaust port from the rising piston????? look at the uncovered exhaust port between 1:19 and 1:21 |
