Unrestrained consumption of petroleum products and harmful emissions generated from them are of great concern globally. Because of stringent emission legislation, researchers are now focusing on controlling emissions and performance improvement in the existing vehicles. Dual-fuel operation using CNG is an option for emission compliance while improving fuel economy. The dual-fuel mode can be used in both compression ignition (CI) and spark ignition (SI) engines, with gaseous fuel (compressed natural gas: CNG) being the primary fuel and a small proportion of liquid fuel being injected as pilot fuel (Secondary fuel). Due to vast availability, cleaner combustion characteristics, and superior economics, CNG has emerged as an attractive fuel for light-duty and heavy-duty engines. Advanced injection timings, use of oxygenated pilot fuels, EGR, piston bowl geometry optimization, and injector nozzles optimization are the strategies that could be adopted in conventional engines for improving their performance and reducing the emissions in dual-fuel mode. HC, CO, and smoke reduction were observed in dual-fuel engines with advanced injection timings. Combustion simulations and modelling of CNG-diesel dual-engine using the G-equation model are also discussed.
