CPT presenting two papers at SAE World Congress on SpeedStart and TIGERS for 48V mild hybrid systems

Green Car Congress

CPT’s SpeedStart paper (2014-01-1890) describes the specification of a 48V belt integrated starter generator (B-ISG) developed to meet the growing market demand for low voltage mild hybrid passenger vehicle applications. The exhaust gas can reach temperatures greater than 900 °C, whereas the turbine upper functional limit is 850 °C.

Delphi Powertrain Study Concludes 3-Cylinder Turbo Gasoline Direct Injection Engine Offers a High-Value NOx and CO2 Solution for Cost-Sensitive Vehicle Segments

Green Car Congress

The Delphi study assessed the technology of downsizing and turbocharging; GDI fueling and its synergies with turbocharging; and an analysis of downsized 3-cylinder versus 4-cylinder engines. Downsizing can be accomplished via reduction in the number of cylinders, and/or a reduction in the displaced volume of each cylinder.

Audi introduces new high-efficiency 2.0L TFSI based on Miller cycle; 190 hp, 47 mpg

Green Car Congress

Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. Contributing to this benefit is also the exhaust manifold, integrated in the cylinder head. Stansfield, P., and Freeland, P.

Ford study suggests GDI engines can meet coming California and US PM emissions standards over 150k miles; more work to be done

Green Car Congress

The EU has already set a standard for 6 × 10 12 number/km limits between 2014 and 2017, tightening to 6 × 10 11 number/km.). Homogeneous GDI provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. Resources. —Maricq et al. Credit: ACS, Maricq et al.

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. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010.
