本机的开发目标是:(1)满足地球环保要求;(2)轻量、紧凑,与快艇配套方便;(3)低噪声、低振动和舒适性好。其特征是既有不逊于二冲程发动机的航行性能,又在重量与尺寸方面优于通常的四冲程发动机,同时,还通过进气系统长进气管的惯性增压及电子控制喷油量的适当调节,降低燃油耗。介绍了在降低噪声、振动等方面所采取的技术措施,进排气系统与驱动系统的结构特点。
The development objectives of this machine are: (1) to meet the global environmental requirements; (2) lightweight, compact, convenient and speedboat; (3) low noise, low vibration and good comfort. The utility model has the advantages of not only inferior to the performance of the two-stroke engine but also superior to the usual four-stroke engine in terms of weight and size, and at the same time, the inertial pressurization of the long intake pipe of the intake system and the electronic control of proper adjustment of the fuel injection quantity , Reduce fuel consumption. The technical measures taken to reduce noise and vibration are introduced, and the structural characteristics of intake and exhaust system and drive system are introduced.
