KAUST team develops method for reliable prediction of abnormal ignition phenomena

Green Car Congress

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.

New 4-cylinder 2.3L EcoBoost on Lincoln MKC small SUV; future EcoBoost prospects

Green Car Congress

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

Advanced ADEPT 48V affordable mild hybrid on path to meet future ultra-low vehicle emissions

Green Car Congress

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.

KSPG shows new compact two-cylinder range extender for EVs, variable valve system

Green Car Congress

UniValve is a mechanical system for the simultaneous and continuous adjustment of valve lift and opening event. Through early closure of the intake valve, both the gas exchange work and the (directly related) specific fuel consumption steadily decrease. The control shaft is driven by a wear-free, brushless electric motor.

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).

SwRI to Launch Low-Speed Preignition Prevention Program (P3) Consortium

Green Car Congress

LSPI is considered an impediment to aggressive engine downsizing to reduce carbon dioxide emissions. Low-speed preignition events are random, infrequent occurrences that happen at low speed and high torque, and their causes are not completely understood. Earlier post.).
