Abstract
The legislative framework for new Internal Combustion Engines for the next years is currently being defined, with the review of the light-duty CO2 emissions standards and Euro 7 proposal to regulate pollutant emissions under a wide range of driving conditions. Despite a −100% tailpipe-only CO2 target by 2035, some perspective is kept for the potential role of vehicles running exclusively on e-fuels.
This study investigates a gasoline demonstrator vehicle equipped with a 48 V mild-hybrid powertrain and a 1.5 L direct injection engine. The innovative emission control system consists in project phase 1 of a three-way catalyst (TWC) in close-coupled position, in combination with an underfloor catalysed gasoline particulate filter (cGPF), second TWC and ammonia slip catalyst (ASC). In a project phase 2, an electrically pre-heated catalyst (EHC) is integrated in the close-coupled TWC canning.
Pollutant emission tests on reference E10 fuel are conducted on a challenging chassis dyno test for cold-start emissions at 23 and −10 °C. The results show the system achieves near-zero pollutant emissions when the emissions control system is warm. The initial cold-start peak is reduced compared to already low Euro 6d levels. All data is within the Euro 7 boundary conditions and limits of the Euro 7 proposal.
Tests were repeated on Blue Gasoline and e-gasoline, confirming ultra-low pollutant emissions while achieving significant CO2 emissions reduction on a Well-to-Wheel basis.
