BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. 2010) Valve-Event Modulated Boost System, SAE Technical Paper 2010-01-1222 doi: 10.4271/2010-01-1222.

Google and IEEE launch $1M challenge for downsized inverters

Green Car Congress

In the event of a tie on volume, efficiency will be used to determine the grand prize winner. inverter used in the Fiat 500e has a volume of about 5 liters, while the motor inverter used in the 2010 Prius drivetrain has a volume of about 5.4L (according to a DOE deconstruction.) As a few points of comparison, the Bosch INVCON 2.3

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

Since 1990, however, the ESCII (2010 = 100) has remained essentially static, changing by less than 1%. tCO 2 /toe); in 2010 it was 56.7 Engine downsizing and weight reduction represent around 30% of that potential collectively. In 1990 the underlying carbon intensity of supply was 57.1 tCO 2 /TJ (2.39 tCO 2 /TJ (2.37

DOE awards Envera $2.8M to develop and to test efficient variable compression ratio engine

Green Car Congress

The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Valve events will also be adjusted with the VVA to trap more air in the cylinders when power is needed. Engine downsizing is a key tool in improving fuel economy. Earlier post.).
