Abstract
An internal combustion diesel engine has a fuel injection means for injecting fuel directly into one or more combustion chambers. Each combustion chamber has a first air-intake duct for supplying air to the combustion chamber, which first duct is designed as a swirl duct. A second air-intake is associated with each combustion chamber and is connected in parallel with the first duct for supplying an increasing quantity of substantially swirl-free air to the combustion chamber in response to increasing engine speed.
