,Water injection for gasoline engines – potentials and challenges,Specific engine power has significantly increased within the last decades as can be seen in Figure 1. For mass production powertrains a power density of more than 85 kW/l will be required in the future. On the other side the upper limit of stoichiometric operation has almost kept constant over the last years.

How to address durability-related challenges in commercial vehicle gas engines,Engine developers for heavy duty commercial vehicles face major challenges in the coming years. On the one hand, more stringent pollutant levels are being discussed and partly already implemented. On the other hand, limitations on greenhouse gas emissions will require further improvements in fuel economy.

Hydrogen as the basis for mobility with a low carbon footprint: from a fundamental, technological, In nature, hydrogen (H) occurs in large quantities only in combination with either oxygen (O), in the form of water (H.O), or carbon (C) in the form of natural gas, which mainly consists of methane (CH.), as well as in the form of crude oil (CH.), coal (CH) or biomass (CHOH).

Electric turbo, a key technology to achieve Eu7 hybridized powertrain (lambda 1, performance and end Powertrains. Hybridization will rise rapidly as it is the most cost effective route to lower emission and fleet CO2 in a period where cost, infrastructure and customer acceptance will still be significant ‘barriers to entry’ for fully electrified Vehicles such as BEV and FCEV.

Combined application of 3D-CFD and high-speed video endoscopy on a turbocharged GDI engine,th turbocharging plays a key role for a further reduction of CO2 emission. A major challenge for these kinds of engines is the reduction of particle number emissions (PN), whereby the injection system is the key component.
