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., fuel with higher ethanol content—for part- and full-load operation for different engine types and fuel assumptions. In their study, Leone et al.

Achieving these goals enabled vehicle integration that can tune primary engine orders in the induction and exhaust systems to meet specific vehicle objectives. Opel’s SIDI ECOTEC is the only engine in its class to offer balance shafts, according to GM. The engine retains the proven concept of a turbine-integrated exhaust manifold.

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.
