New HCCI/CAI Combustion Process Development: Methodology for Determination of Relevant Fuel Parameters — To pass the simultaneous emission requirements for near zero pollutant and low CO2 levels, which are the challenges for future powertrains, many research studies are currently carried out over the world on new engine combustion processes, such as controlled auto-ignition (CAITM) for gasoline...

Ammonia (NH3) is recognized as a carbon-free hydrogen-carrier fuel with high content of hydrogen atoms per unit volume. Recently, ammonia has received increasing attention promising alternative for internal combustion engine and gas turbine applications. However, the viability fueling future devices several barriers to overcome. To overcome challenge its low reactivity, it proposed blend high-r...

Homogenous Charge Compression Ignition (HCCI) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. But in contrast to gasoline and diesel engines, HCCI engines suffer from lack of having direct means to initiate combustion. A combustion timing controller with robust tracking performance is the key requirement to leverage HCCI application in production ...

The greenhouse effect and limitations on carbon dioxide emissions concern engine maker and the future of the internal combustion engines should go toward substantially and improved thermal efficiency engine. Homogeneous charge compression ignition (HCCI) is an alternative high-efficiency technology for combustion engines to reduce exhaust emissions and fuel consumption. However, there are still...

In the current study, an effort is carried out to study influence of pentanol as low reactive fuel (LRF) along with diesel and Thevetia peruviana methyl ester (TPME) high fuels (HRF) in reactivity controlled compression ignition (RCCI) engine. The experiments are conducted on dual engine at 50% load for RCCI mode operation by varying percentage injected fuels. results revealed that 10% exhibite...

The increasing environmental concern caused by the use of fossil fuels and the concomitant need for improved combustion efficiency is leading to the development of new coal cleaning and utilisation processes. However, the benefits achieved by the removal of most mineral matter from coal either by physical or chemical methods can be annulled if poor coal combustibility characteristics are attain...

Diesel engines are the most commonly used internal combustion engines nowadays, especially in European transportation. This preference is due to their low consumption and acceptable driveability and comfort. However, the main disadvantages of traditional direct injection Diesel engines are their high levels of noise, nitrogen oxides (NO x) and soot emissions, and the usage of fossil fuels. In o...

Spray characteristics have an important role in improving the quality of combustion compression engines. This study analyzes effect ambient temperature on spray including tip penetration, angle and velocity spray. The research method uses experimental with variations 60 o C, 80 100 C controlled using a thermocouple pressure 0.3 MPa. composition fuel diesel (diesel 100%), B30 (30% biodiesel), B1...
