In a paper presented at the 2019 Vienna Motor Symposium this week, Delphi Technologies will unveil a new 500+ bar GDi system that can reduce particulate emissions by up to 50% compared to state-of-the-art 350 bar system without expensive engine design modifications. Delphi 500+ bar GDi pump. Delphi 500+ bar GDi injector. —Walter Piock.

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. 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.

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. However, the cycle results in higher HC and CO emissions due to the low in-cylinder temperature.

Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future. Combustion engines still have potential to save energy and reduce emissions; a current trend is to use downsized engines of the same or even increased power.

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).

liter model but with significantly reduced real-world and drive cycle CO 2 emissions, and comparable improvements in fuel-economy. In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Earlier post.). three-cylinder EcoBoost engine.

FEV’s 698 cm 3 Extremely Downsized Engine. will show its Extremely Downsized Engine (EDE) at next week’s 2010 SAE World Congress in Detroit. Direct injection (DI) is integrated by replacing the twin spark ignition with a single spark plug on the exhaust side with the DI device in place of the removed spark plug on the intake side.
