“…Gasoline direct-injection (also referred to as spark-ignition, directinjection) technology has the potential to improve the fuel economy of gasoline engines by 22% to 24% (21,22) but is unlikely to meet emissions standards without emissions-control equipment that requires frequent regeneration. When fuel consumption for regeneration is taken into account, the fuel economy gain is estimated to be 8% to 10% (23).…”

The results of an analysis of heavy-duty truck (Classes 2b through 8) technologies conducted to support the Energy Information Administration’s long-term projections for energy use are summarized. Several technology options that have the potential to improve the fuel economy and emissions characteristics of heavy-duty trucks are included in the analysis. The technologies are grouped as those that enhance fuel economy and those that improve emissions. Each technology’s potential impact on the fuel economy of heavy-duty trucks is estimated. A rough cost projection is also presented. The extent of technology penetration is estimated on the basis of truck data analyses and technical judgment.

Researchers at Argonne National Laboratory analyzed heavy-duty truck technologies to support the Energy Information Administration's long-term energy use projections. Researchers conducted an analysis of several technology options that have potential to improve heavy truck fuel economy and emissions characteristics. The technologies are grouped as fuel-economy-enhancing and emissions-improving. Each technology's potential impact on heavy truck fuel economy has been estimated, as has the cost of implementation. The extent of technology penetration is estimated on the basis of truck data analyses and technical judgment. * Under high-technology case, this technology will penetrate sooner. ** Half of the fuel economy gains would be under the high-technology case. ***Contingent on development of practical on-board air separation system and significant lag in fuel sulfur phasedown. This option selected in preference to "lean-NOx" catalysts, the development of which is still plagued by high fuel penalties and low efficiency.
