日本丰田株式会社正在研制具有进排气门的增压式二冲程柴油机,不久将推出.该机巧妙而有效地利用了“丰田”多年来先进的4气门发动机的技术,制成进一步追求高动力性能和平稳性、低排放和低燃油消耗率的发动机.该机基本结构如下,由配置在气缸盖上的4个进、排气门和增压器进行强制扫气,并且采用最新电子技术控制燃油喷射系统和点火系统,以求达到控制燃烧的目的.这种基本结构既可用于汽油机亦可用于柴油机,目前,该机在“丰田”公司尚处开发研制阶段.该机与相同排量四冲程发动机相比,在相同转速下作功次数提高1倍,主要优点是低速扭矩特别大,其次是低振动和低噪声.对于柴油机而言,降低振动和噪声是至关重要的技术
Japan Toyota Co., Ltd. is developing a supercharged two-stroke diesel engine with intake and exhaust valves, which will soon be launched, which makes ingenious and effective use of the “Toyota” advanced four-valve engine technology over the years to make further pursuit High power performance and stability, low emissions and low fuel consumption of the engine.The basic structure of the machine is as follows, by the configuration of the cylinder head 4 inlet and exhaust valves and supercharger for mandatory scavenging, and the latest electronic Technology to control the fuel injection system and ignition system, in order to achieve the purpose of combustion control.This basic structure can be used for both gasoline engine and diesel engine, at present, the aircraft is still under development and development stage of “Toyota” Compared with the same displacement four-stroke engine, the same number of times at the same speed increased by 1 times, the main advantage is that low-speed torque is particularly large, followed by low vibration and low noise .For the diesel engine, to reduce vibration and noise is essential technology
