The advantages and disadvantages of the two stroke engine and the four stroke engine?

Two stroke engine crank rotates a circle a, four stroke engine crank rotation two to do a work, so the two stroke engine torque is four stroke engine has the advantages of uniform, "two stroke engine strong power, is almost two times the four stroke, the drawback is high fuel consumption and fuel consumption rate low emission, serious pollution, not suitable for long-distance use". Four stroke engine intake and exhaust total crank angle is 360 degrees, the exhaust piston top dead point, the exhaust gas discharged forcibly, intake when the piston down to the next stop point, so it has the advantages of fresh mixture into the combustion in almost all, basically no fresh gas waste, therefore low fuel consumption, suitable for long distance service ", and its shortcomings are obvious, the power output is stable, the strength is obviously insufficient.
