소형 트럭용 글로우 플러그 보조 직분식 메탄올 엔진 개발

NOｘ and Particulates from Diesel engines are the main causes of air pollution in city areas. However. the reduction of both NOｘ and Particulates simultaneously is not easily realized. Vehicles powered by Diesel-type Methanol engine are under development to reduce emissions and are under fleet test. Physical and chemical properties of Methanol are compared to use Methanol as a fuel in a Diesel-type engine. Ignition assistance systems in Diesel-type Methanol engine are also compared because ignition assistance system is needed due to poor self-ignition property of Methanol. The way to solve technical problems of Diesel-type Methanol engines are presented as follows; stable self-ignition property under wide operating conditions. combustion improvement, reduction of power consumption and reliability for glow plug by reservoir -type glow plug and by EGR at low load. combustion improvement and elevation of conversion rate of catalyst by throttling at no load, reduction methed of formaldehyde emission.
