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 ).

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., Practically, however, the range of regular-grade gasoline in the US is 89 to 96 RON; vehicles need to be designed to accommodate fuel with the lowest expected octane rating.

The structural design considers the engine’s use in a variety of vehicle applications, allowing minimum integration effort and consistent part interchangeability. Two different pistons have been designed for the Eco and Performance Turbo engines. Each has a dedicated top land including a small bowl. Turbocharging.

We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. The basic approach of the downsized 3-cylinder gasoline direct injection (GDI) engine is to reduce engine displacement and decrease engine speed (downsizing and downspeeding) to increase engine load for improved specific fuel consumption.

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power. Earlier post.)

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). & Northstar used an open deck design (unlike cast iron V8s).
