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.

In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Earlier post.). The HyBoost concept is based on a 2009 Ford Focus in which a 2.0L naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L three-cylinder EcoBoost engine.

Researchers at KAUST’s Clean Combustion Research Center have developed a method to predict and to avoid undesirable combustion events in advanced engines, such as knocking and super-knock. Advanced low-temperature-combustion (LTC) strategies of downsized and boosted engines are capable of offering ultra-low emissions and higher efficiencies.

Featuring a twin-scroll turbocharger and a three-port integrated exhaust manifold (IEM), the 2.3-liter Two pivotal factors are the three-port integrated exhaust manifold cylinder head and a twin-scroll turbocharger. The all-new 2015 Lincoln MKC small premium utility, unveiled last week, offers an all-new engine—a 2.3-liter

The final results will be presented at the UK’s LCV2016 event on 14-15 September. The concept of “intelligent electrification” enables highly aggressive engine downsizing and down-speeding beyond what might normally be possible other than through more expensive hybridization approaches. ADEPT powertrain architecture.

UniValve is a mechanical system for the simultaneous and continuous adjustment of valve lift and opening event. In order to reap the advantages of very early closure, the opening event must therefore be as short as possible. The control shaft is driven by a wear-free, brushless electric motor. In a test involving a turbocharged 2.0-liter,
