二冲程机存在着某些缺点,例如与四冲程机相比,寿命低、燃油经济性差、排气毒性大等,因此许多专家认为这种发动机没有前途.但是,由于近几年来对二冲程机的深入研究,特别是澳大利亚奥尔比达尔公司的二冲程发动机、专利申请及发明证书不仅充分驳斥了这种观点,而且使人们不得不重新评价二冲程机的发展前景,找出产生这些缺点的原因并加以克服.
Two-stroke machine has some shortcomings, such as low life expectancy, poor fuel economy, high exhaust gas toxicity compared with the four-stroke machine, so many experts believe that this engine has no future.But, in recent years, two-stroke machine In-depth research, in particular the Australian two-stroke engine from Orbitar, Australia, not only fully dismisses this view, but also makes it necessary to re-evaluate the development prospects of two-stroke engines and identify the shortcomings that have caused these shortcomings Cause and overcome.
