Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

So far, Ruth noted, the new engine has achieved target engine-out emissions (EOE), performance and fuel economy; aftertreatment catalyst performance has met or exceeded the targeted conversion rates, enabling an increased allowance on engine out HC. liter) and its emission control system (ECS) without a weight penalty.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. Source of data: US EPA (2019).

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.

Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations. Exhaust gases provide an efficient and as yet unutilized method of power regeneration, particularly for a throttled gasoline engine, and further helps improve fuel economy and reduce CO2 emissions.
