2 stroke
« on: July 04, 2003, 07:16:39 AM »
Is 2 stoke motorcycle phased out?  What is it's advantage over the 4 stroke counterpart?

Nope it's not phased out. You could still buy 2-stroke mc's although what I heard is that the manufacturers are seriously thinking of stopping their production.
based on what i undertand, 2 stroke are a lot faster in acceleration, although 4-stroke have more torque.

2-stroke engines hav less moving parts thus giving them a lighter weight.

sixpack, your all over the talkboards huh! sarap ng buhay natin ah. papindut-pindot lang. ;D

aside from the things mentioned above about 2 stroke, 2 stroke engines have a mixture of 2t oil and gasoline to keep it going. this explains why 2 stroke engines emit more smoke than 4 stroke (pure gasoline).

yes, the extra smoke comes from the unburnt 2t oil. usually during no load on the engine, but during high revs and high speed, it is lessen. u can see it when u watch racing  on grand prix or motocross

Performance wise, i prefer a 2 stroke over a 4 stroke in small to medium displacements. (100 - 250 cc).  mainly because the immediacy of acceleration is more apparent with small 2 stroke motors.  This is less noticeable on large displacement engines.  The other characteristic of the 2 stroke is to have a very wide powerband due to its propensity for higher rpm's.  This is why you don't normally see 4 stroke engines in motocross races on the smaller displacements.  The parallelism is like talking about the characteristics of a gas motor over a diesel motor.  The diesel engine has more GRUNt at low rpm but less GO. Just my 2 cents.  Hindi na kasi pinapayagan mag motor ni Misis eh!

WIDE POWERBAND......power from low to high rpms? baka meron ka pang additional explanation....

thanks

OT:
wolverine,

do u still have the "appetite to ride one" ? lalo na kung me dumadaan sa tabi mo?

Ted:  Yes powerband can be defined as the rpm range at which an engine continuous to make hp.  On a 4 stroke engine, the band is "narrower" due to a more complex engine design.

As to whether i still have an appetite to ride one.....The answer is a definite YES!!! Although I am pretty sure that I would probably be more tame now that I'm much older.  Pero alam mo naman na ang desire minsaan parang apoy din yan na namamatay pag laging binubuhusan ng tubig ;)
