This review offers a summary of the recent research progress on hydrogen enriched
compressed natural gas (HCNG) engines. Spark ignition IC engines fueled by HCNG have …

Gaseous fuels, eg, natural gas, biogas, have several advantages over liquid fuels owing to
their favorable physical and chemical properties, eg, lower carbon numbers in the fuel …

Natural gas has been identified as one of the most promising alternative fuels. Port injection
of natural gas, due to its advantages of costs, manufacturing complexity and mixture …

This study shows the effects of different injection strategies for methane, hydrogen and
hydrogen-enriched methane in a single-cylinder spark ignition engine. In port fuel injected …

The present paper provides a contribution to the CFD modelling of reacting flows in IC
engines fueled with natural gas. Despite the fact that natural gas has been widely …

A customized port-fuel-injection (PFI) SI engine was operated in spark ignition (SI) and laser
ignition (LI) modes at varying brake mean effective pressure (BMEP) and relative air-fuel …

The present paper is focused on the development of a high-performance, monofuel, spark
ignition engine running on natural gas, featuring a high volumetric compression ratio and a …

Natural gas is a promising alternative fuel for internal combustion engine application due to
its low carbon content and high knock resistance. Performance of natural gas engines is …

This paper investigates into the mixture formation in a direct injection, turbocharged, spark-
ignition, CNG engine. The engine features a pent-roof combustion chamber, a bowl in piston …

The massive use of automotive has a terrible effect on the environment. The unsafe
pollutants as HC, CO, NOx, and CO 2 are emitted from the IC engines during incomplete …
