Potential of Valve Train Variability in Passenger Car Diesel Engines
Variable valve control systems are state-of-the-art technology in today's gasoline engines, although their application in diesel engines has also become the focus of recent studies. These systems offer one possibility of resolving the conflict of objectives between a further reduction in engine-out emissions and an improvement in fuel efficiency. Mahle has examined their potentials on the basis of the Cam-in-Cam variable camshaft for the intake valves.

Simplified High Performance Injection Systems for Dual-fuel Engines
With their fuel flexibility and low emissions in the gaseous fuel mode, dual-fuel engines are increasingly popular. Currently, they require two fuel injection circuits, one for pilot injection in...
Characterisation of Large Gas and Dual-fuel Engines
Engines burning gas or combinations of gas and liquid fuels have become popular in recent years, but due to lack of an established nomenclature designations have become somewhat confusing. In order...
Bearing Technology Combinations for Low Friction Cranktrains
The focus of emissions legislation has now expanded to include carbon dioxide and other greenhouse gases with challenging targets set for the total efficiency of complete engine-powered systems....
