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
In a two-stroke engine, the crankshaft completes one full revolution for every power cycle. This means that for every two strokes of the piston (one upward and one downward), the crankshaft makes one revolution. This design allows for a power stroke with each crankshaft rotation, resulting in higher power output relative to the engine size.
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
The recommended oil to use for mixing with gas in a two-stroke engine is two-stroke engine oil.
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.
