Prototype Development Of A Methanol Engine For Heavy-Duty Application-Performance And Emissions

Combustion and emission characteristics of a two-stroke diesel engine operating on alcohol

“…On the engine side, most of the methods have focused on autoignition by thermal to provide hot spots or increase gas temperature prior to ignition to meet requirements of higher ignition temperature for alcohol. Among these technologies, the most popular one is to use glow plugs or spark plugs, which are relatively easy to control, but readily erosive [3,4]. Other measures, such as increasing compression ratio (CR), preheating intake air and utilizing EGR heat [5][6][7], can compress alcohol to ignite.…”

Application of the New City-Suburban Heavy Vehicle Route (CSHVR) to Truck Emissions Characterization

“…Although there are claims that certain species in the tailpipe are reduced, relative to diesel, when employing biodiesel (1,2), FischerTropsch fuels (3) alcohols (4,5) and natural gas (6) it is difficult to quantify the actual in-use benefits unambiguously because the test schedule used can influence the conclusions reached.…”

The practical implementation of methanol as a clean and efficient alternative fuel for automotive vehicles

“…It turns out to be a reliable solution to deal with the huge latent heat of evaporation of methanol, utilizing existing components and infrastructure, unlike those measures that had to rely on high-energy ignition systems, engine block heater or higher compression ratio for compression ignition. 17,18 This gasoline-assisted cold start might be even more attractive, given the HC emission requirement at −7 °C for China VI emission regulation, to avoid extended period of cold cranking time, thus excessive HC, CO and aldehyde emissions.…”
