An Assessment of Flow Characteristics and Energy Levels from a Gaseous Fuel Injector using Hydrogen and Natural Gas 2001-28-0031

Fuel induction techniques have been found to be playing a very sensitive role in the operation of a gas-fueled engine. This paper describes the experimental evaluation of an electronic injector for operating a spark ignition (SI) engine using clean-burning alternative fuels such as compressed natural gas and hydrogen. Test data have also been generated with a blend of the two fuels (hydrogen and CNG) in various proportions to determine the flow characteristics of the blend for engine operation.
Results show that the electronic injectors for gaseous fuel operation can be conveniently adapted to existing engines. A precise and accurate control of flow was achieved at pressure levels of 3.44 bar and 9.31 bar (absolute pressure).
