Abstract
The work performed for this project was in part of the effort of the Department of Energy Sponsored program called ‘SuperTruck’. The entirety of the Supertruck program encompasses total vehicle re-design to achieve 80% freight efficiency improvement (over the 2009MY baseline production vehicle). However, the other main goal for the program is to achieve 50% engine brake thermal efficiency. The work outlined in this document describes the efforts performed on base engine and thus mainly contributing towards 50% BTE. Though ultimately reducing BSFC by increasing BTE contributes to both outcomes. The engine development data discussed in this paper was collected in a test cell at normal altitude and normal operating temperatures. The bulk of the work that comprises this paper are in the research and development of new prototype and experimental hardware, and the calibration of such to maximize its performance yet still meet constraints. Constraints of the project are: the vehicle still needs to meet a 0.2 g/bhp-hr FTP-RMC combined tailpipe out NOx requirement, cylinder pressure limits for hardware durability, soot - and still maintain drivability - as the vehicle will be driven at what was determined a mean load of 68,000 pounds. A mule vehicle was built, referred to as ‘T3’, that encompassed some of the technologies and was demonstrated a year before the ‘T4’ truck was completed as to outline the team’s progress on our path to the program’s goals – some of that work is also discussed in this document. A MY2009 truck, used as a control, was also used to set baseline results, and will be referenced in this document.
