Abstract Past research has shown that Reactivity Controlled Compression Ignition (RCCI) and Gasoline Compression Ignition (GCI) combustion are promising approaches to improve efficiency and reduce pollutant emissions. However, the benefits have generally been confined to mid-load operating conditions. To enable practical application, these approaches

Volume 1: Large Bore Engines; Fuels; Advanced Combustion, 2015
Due to growing interest in utilizing natural gas as an alternative fuel in internal combustion engines, a study on the use of natural gas for dual-fuel combustion strategies in a heavy-duty engine was performed to examine the diesel pilot ignition (DPI) and reactivity controlled compression ignition (RCCI) combustion strategies. In Part 1 of this work,

Reactivity controlled compression ignition with triple injection fuel: ethanol–diesel–ethanol
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2020Enabling diesel engines to operate with other fuel can be a solution to reduce the pollution generated by these machines. However, the peculiar physicochemical characteristics of each fuel make it difficult. Ethanol, for example, needs different temperature and pressure parameters to ignite, compared to diesel.

Journal of Engineering for Gas Turbines and Power, 2011
The present study uses numerical simulations to explore the use of hydrated (wet) ethanol for reactivity controlled compression ignition (RCCI) operation in a heavy duty diesel engine. RCCI uses in-cylinder blending of a low reactivity fuel with a high reactivity fuel and has demonstrated significant fuel efficiency and emissions benefits using a ...
