The disadvantage of two-stroke engines is that current technology cannot solve them.
High fuel consumption
Because of its ventilation method
Itself Check it out
It’s very polluting
Because the lubricating oil is involved in the combustion
It is also caused by incomplete combustion
What I find strange is
Wouldn’t it be better to change the two-stroke engine to direct injection in the cylinder
Change the lubrication method to a four-stroke one
No one thought of this
There must be some problems
For example
Direct injection systems are expensive, etc.
So the technology will develop in the future
II Strokes will become popular again
