Combustion-Generated Noise: An Environment-Related Issue for Future Combustion Systems

Reducing Combustion Noise

The design and development of modern internal combustion engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque. Correspondingly, combustion noise excitation and fuel consumption also have to be reduced. These objectives can be achieved through the development of advanced combustion systems, the increased flexibility of fuel injection systems and ECU...

Research needs for future internal combustion engines

Transportation is second only to industrial use as the largest consumer of energy in the US and accounts for about 60% of our nation’s use of petroleum—an amount equivalent to all of the oil the country imports. The numbers are staggering: Some 10 000 gallons of petroleum are burned in the US each second of every day. Although new energy sources are being developed and renewable fuels are emerg...

Editorial Special Issue “Combustion and Propulsion”

The increasing demand for socially and environmentally sustainable development requires appropriate use of energy resources, particularly in the transportation of people and goods. The main source of energy for propulsion is based on the use of fuels, mainly of fossil origin but increasingly produced from renewable sources. Therefore, combustion processes play a key role in the efficiency of en...

LES of spray and combustion in an internal combustion engine

With the ever rising need for better fuel efficiency and lower emissions, the development of better engine technology is essential. Different strategies are being considered to increase engine efficiency, such as direct injection or downsizing. Certain regimes are clearly identified as optimal for certain range of loads. For gasoline engines, the Homogeneous Charge Compression Ignition (HCCI) c...
