Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

–Fast depletion of fossil fuels demands an urgent need to carryout research to find viable alternative fuels such as Hydrogen, LPG and CNG. The gaseous hydrocarbons seem to be best immediate option presently available[1]. The remarkable feature of gaseous fuels are the absence of mineral impurities, the consistency in quality and the convenience and efficient in use. LPG is used widely as a co-...

It is well known that hydrogen addition to spark-ignited (SI) engines can reduce exhaust emissions and increase efficiency. Micro plasmatron fuel converters can be used for onboard generation of hydrogen-rich gas by partial oxidation of a wide range of fuels. These plasma boosted microreformers are compact, rugged, and provide rapid response. With hydrogen supplement to the main fuel, SI engine...

Exhaust gas recirculation (EGR) is one of the main techniques to enable use oxyfuel combustion for carbon capture and storage (CCS). However, recirculated streams with elevated dioxide poses different challenges. Thus, more research required about cumulative effects on desirable outcomes processes such as thermal efficiency, reduced emissions system operability, when fuels high CO2 concentratio...
