Gaseous Fueled Spark-Ignition Engines

Call for Papers

The rapid depletion of petroleum resources and their environmental concerns have focused attention on developing clean burning renewable alternative fuels. Gaseous fuels, for example, (compressed) natural gas, biogas, syngas, LPG (liquefied petroleum gas), and hydrogen offer promising alternatives as power sources for internal combustion engines. Gaseous fuels have high hydrogen to carbon ratios, form homogeneous mixtures with air to promote complete combustion and offer low pollutant levels, and can be utilized with relative ease in spark-ignition (SI) engines. A premixed gaseous fueled engine, however, suffers from power output compared to its gasoline counterpart due to decrease in volumetric efficiency. This may be recovered in part (limited by engine knock) by increasing the compression ratio or utilizing the turbocharger boost. Hence, understanding of combustion characteristics over a wide operating range is important for optimal engine performance. The direct-injection concept with increased compression ratio has the potential to increase thermal efficiency and reduce CO2 emissions.

Advanced combustion strategies, such as stratified mixture combustion (widely studied for gasoline), are of interest to increase lean burn limits of gaseous fueled spark-ignition engines and increase the low load thermal efficiency. Mixture formation and combustion processes of gaseous fueled engines must be well-understood to meet upcoming fuel economy and emission regulations. Optical engine studies are helpful to gain fundamental understanding of incylinder processes and provide validation data for multidimensional numerical simulations. Modeling and simulation efforts are required to reduce the development time of engines operating under gaseous fuels. Also, the composition of gaseous fuel(s) can vary significantly with location and climate, which considerably influences the engine performance, combustion, and emission characteristics. We welcome investigators to contribute their original research articles related to gaseous fueled spark-ignition engines.

Potential topics include but are not limited to the following:

  • Use of different gaseous fuels, and influence of fuel composition variation on performance, combustion (including ignition, flame propagation, and knock), and emission characteristics
  • New combustion strategies for improvement of fuel economy and exhaust emissions
  • Modeling of engine or engine components
  • CFD simulation of gaseous fueled SI engine
  • Visualization studies to understand the mixture formation and combustion process
