when the piston moves up in two stroke engine first of all it covers the scavenge ports and then when it moves little bit up then cylinder lube oil is injected between the piston rings. when it further moves and compress the scavenge air and the temperature of the air inside the cylinder increases above the auto ignition temperature of the fuel oil. and before the piston reaches TDC the fuel is injected and hence the combustion begins.
Explain the advantages of four-stroke engine over two-stroke engine
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
Detroit diesel engine is an example of two stroke engine
two stroke
I'm not sure if you are talking about oil or the gas.In case of the gas -It will run. no side effects.
You freeze up the engine
A two stroke engine has half the strokes of an otto (or four stroke) engine, therefore it takes two crankshaft roatations to complete a cycle on a four stroke engine and only one revolution in a two stroke engine. There are several types of two stroke engines, the different types have to do with how the receive the air/fuel mixture, also you have two stroke diesel engines.
suction stroke and exhaust strokes are the two strokes involved in 2 stroke engine....
By putting only gasoline in a two stroke engine you can destroy it. A two stroke engine requires oil to be mixed into the gasoline to keep the moving parts lubricated. When you do not have that oil there it will not lubricate correctly and therefore scar and break the moving parts on the inside.
Yes, a Vélosolex has a two-stroke engine.
You can use four stroke oil for a (very) limited period in a two stroke engine in an emergency. However it is not formulated for two stroke engines and is not recommended.
No it isn't fatal, but it would smoke quite a bit, because a two stroke engine needs two stroke oil mixed in the petrol, and a four stroke just needs petrol.
