You have to mix oil into the gas in a two-stroke engine because the holes in the cylinder wall prevent the use of rings to seal the combustion chamber.
在二沖程發(fā)動(dòng)機(jī)中你必須混和燃料和氣躰，因爲(wèi)氣缸壁上的孔阻止使用活塞環(huán)密封燃燒室。
Poor fuel quality. Incomplete combustion and lack of sealing between piston and cylinder wall or badly losing valves. Possibly incorrect engine timing / set up.
燃油品質(zhì)差，不完全燃燒和活塞與氣缸壁之間的密封性差。還有可能不正確的發(fā)動(dòng)機(jī)正時(shí)/設(shè)置。
