i m know that a mixture which entering in the lower case of the cyllinder is transfer to the combustion chamber and carburettor sent a air and petrol mixture to the cyllinder. But i want to know after entering the mixture in the cyllinder by carburettor is lubricating oil also add in it before going to the combustion chamber. If you know the answer please sent the answer on my yahoo as well as in my gmail id "piyushaggarwal786@gmail.com"

ok you say yes but i m also want to know that is lubricating oil also burns with the fuel in the combustion chamber.

Two strokes have oil in the crankcase for the lubrication of the crank, rod, and main bearings. Oil is mixed with the gas(petrol) in the tank for lubrication of the valvetrain and upper cylider.

YES lubriating oil passes through engine with the air fuel mixture. It uses the internal crankcase area as a suction camber to provide lubrication to the cylinder,piston rings and crank and rod bearings. Two stroke engines pass their oil-air- fuel mixture into the crankcase before reaching the combustion chamber this is where it lubricates the crank bearings and rod bearings. Then it moves into the combustion chamber which is controlled by piston movement not by a valve mechanism(flow through the engine is controlled by the piston covering and uncovering ports in the cylinder wall). this mixture has enough oil to lubricate the cylinder piston and rings. The burnt air fuel oil mixture is exhausted during the power stroke. Most of the oil is burnt at this time why two strokes smoke.

Yes, the oil is burned with the fuel/air mixture in the combustion chamber. That's what makes 2 cycle and 4 stroke motor oil different. 2 stroke oil is very thin. Thin enough to burn when ignited and have just enough lubrication to lube the crank bearings, connectiing rod, piston, rings and cylinder.

Dear freind.
In a two stoke vehicle of olden days(EX yEZDI, BAJAJ ETC) THE LUBE WAS MIXED WITHE PETROL HENCE IT WAS INJECTED IN TO THE CYLINDER along with the air which is one of the combustion element.You may note here that the viscosity of the luybe ( oil ) will not allow the cumbustion at the fast pace as compared to the petrol and hence the lube will go through the job for which it was used

Yes
But the oil does not burn completely. it carries away some of the soot and settles in the crank case. This is also the reason why two strokes need regular oil top up, and draining of crankcase during servicing, or in the case of the older engines, the oil is actually mixed with the fuel during filling.

two strokes got two kind of oil normally - engine oil and transmission oil.
lubrication of all bearings are taken care of by transmission oil( crank case or sump oil)
engine oil can be inducted into the system by mixing it with petrol (almost all scooters) or can have a separate injection system with a metering pump regulated by the accelerator ( most of the 100cc bikes)
any way part of oil gets burned and rest undergo incomplete combustion. purpose of engine oil are
1. efficient sealing between piston rings and bore
2. protection of cylinder surface from flame impingement
3. reduce corrosive attack by acids of combustion

Yes it is.The oil fuel mixture has too lubricate the crank bearings , cylinder wall and piston rings.

It would have to be to lube the big end bearing now wouldn't it?
