SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. Making a relevant impact on pollutants requires a whole system approach. g/hp-hr NO x emissions).

ORNL team achieves diesel-like efficiency with SI engine

Green Car Congress

A team at Oak Ridge National Laboratory (ORNL) has achieved diesel-like efficiency in a single-cylinder spark-ignition (SI) research engine while maintaining compatibility with stoichiometric 3-way catalyst (TWC) systems. A major benefit of SI engines is that they allow the use of low carbon content fuels like methane and propane.

Global Clean Energy buys Bakersfield refinery for $40M, converting to produce renewable diesel

Green Car Congress

Historically, the refinery has produced diesel from crude oil and has a capacity of 70,000 barrels per day. GCEH will immediately commence retooling the refinery to produce renewable diesel from organic feedstocks such as vegetable oils. a Primoris Services Corp subsidiary.

Achates near-zero heavy-duty opposed-piston diesel enters fleet service; compliant with 2027 NOx levels

Green Car Congress

liter, heavy-duty opposed-piston, three-cylinder diesel engine it developed in a project funded by the California Air Resources Board (CARB) and several partners ( earlier post ) has entered fleet service with WALMART Corporation in a Peterbilt 579 tractor. The project team also demonstrated that the engine reduces carbon dioxide by 10%.

Study finds that California clean diesel programs have slashed black carbon, a powerful short-term contributor to global warming

Green Car Congress

California’s air quality programs have forced a reduction in black carbon despite a significant increase in diesel fuel consumption. The reductions occurred during a time when diesel fuel consumption increased by about a factor of five. It is a win-win solution if we also mitigate carbon dioxide emissions simultaneously.

Researchers show economic, environmental and grid-resilience benefits of converting diesel trains to battery-electric

Green Car Congress

In the US, diesel freight trains emit 35 million metric tons of CO 2 annually and produce air pollution that leads to $6.5 Here we show that a 241-km range can be achieved using a single standard boxcar equipped with a 14-MWh battery and inverter, while consuming half the energy consumed by diesel trains. revenue-tonnes.
