Abstract | The initial project discussed in this report was to develop an 8.9L natural gas engine capable of meeting increased power ratings and reduced exhaust emissions. The power target was achieved, and the torque and emissions targets were surpassed. Because of the high torque and low NOx requirements, the engine design required increased levels of turbocharging and lean combustion operation. This created challenges related to the ignition system and mixing of the fuel and air to provide a homogeneous mixture and stable combustion, which resulted in a new spark plug design. Hardware revisions to the engine control module (ECM) were necessary to accommodate the new system requirements for sensors and ignition system interface. |
