BorgWarner expands emissions business with new facility in India

Green Car Congress

FEBRUARY 8, 2013

BorgWarner opened a new 86,000-square-foot (8,000-square-meter) facility in Manesar, India, near New Delhi to produce exhaust gas recirculation (EGR) coolers, tubes, valves and modules. Today’s downsized engines generate higher temperatures in the combustion chamber forming nitrogen oxide (NO x ).

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

AUGUST 25, 2015

A team of engineers from GM Powertrain, Ford and FCA have published a detailed review of how to estimate the engine efficiency benefits of higher octane fuel—e.g., To achieve continued improvement in engine efficiency and CO 2 emissions, it is critical to quantify the roles of fuel octane rating and alcohol content.

Some of the best passenger vehicles today, the ones called PZEVs, are pretty close to zero emissions. Under California’s vehicle emissions ratings, PZEVs (Partial Zero Emission Vehicles) meet SULEV (Super Ultra Low Emission Vehicle) tailpipe emission standards and also have zero evaporative emissions.

rather than the development of a new engine, GM brass decided a new power plant was in fact necessary. That was combined with an ill-timed secondary round of downsizing and a switch to more efficient front-wheel drive platforms (except Brougham). millimeters toward the exhaust side of the combustion chamber to improve efficiency.
