2017, Downsizing, Exhaust and Standards

Calls for an international 48V electrical standard for vehicles; looming WLTP implementation

Green Car Congress

DECEMBER 1, 2014

At the 2 nd International Conference Automotive 48 V Power Supply Systems , held last week in Düsseldorf, Germany, Controlled Power Technologies (CPT), a major sponsor of the event, together with leading car makers and Tier 1 suppliers, argued the need for an internationally agreed 48V electrical standard.

FEBRUARY 22, 2018

Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust. The rapid market penetration of GDI vehicles has led governments to impose stricter standards to control PM emissions.

The very high octane rating and resulting high resistance to knock is promising for small, supercharged, downsized SI engines. The Direct4Gas researchers and engineers will design samples of a direct injector that satisfies much higher standards than the manifold injection valves used up to now. By 2025, this limit could be even lower.

While policies worldwide are tightening emissions and fuel economy standards, the strictest standard of all is expected in Europe in 2020, Bohr said—average fleet CO 2 emissions of 95 grams per kilometer. This will be done with a broad range of efficiency-enhancing technologies, including the turbocharging of downsized engines.

DECEMBER 9, 2016

This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today. Regional highlights include: In North America, more engine downsizing is expected. The current average engine size is a 3.0-liter

Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. All the vehicles were tested using commercial gasoline that met the summertime California fuel standards.
