ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

ZF has produced 2M electric motors; mild-hybrid to full-electric drives

Green Car Congress

ZF decided years ago to deploy its own technology of concentrated windings, which is now used for electric motors in hybrid applications. This was necessary because, with purely electric drives, the running speed of the electric motor is no longer coupled with the combustion engine. ZF sees essential approaches in cooling.

Empa team develops electrohydraulically actuated cam-less valve train; up to 20% fuel savings at low load

Green Car Congress

The FlexWork valve train was mounted on a serial production engine and has been running successfully in test bench operation for several months. The valve train is the “respiratory organ” of combustion engines: it manages the aspiration of fresh air and the discharge of exhaust gases (gas exchange). Image: Empa.
