Summary

After Mercedes-Benz launched the first lean-combustion gasoline engines with sprayguided combustion in 2006, it rolled out this technology on a broad level based on the engine model series featuring the BlueDIRECT combustion system. Although these engines raise the bar among competitors in terms of fuel consumption, they are currently available only in countries that offer sulfur-free fuel. This leads to the question of what technical measures or altered constraints would be necessary to allow this environmentally-friendly technology to enjoy more widespread use. The following paper discusses how the accessibility of the lean-combustion technology can be improved by focusing primarily on the USA and China as potential markets.
