Combustion Engine

摘要

A combustion engine has at least one cylinder with a gas exchange inlet valve and a gas exchange outlet valve. A fuel injection device injects fuel directly into the cylinder. A fresh air section can be connected intermittently for fresh gas transmission to the cylinder via the gas exchange inlet valve. An exhaust section can be connected intermittently for exhaust gas transmission to the cylinder via the gas exchange outlet valve. A throttle element is provided in the fresh air section ahead of the gas exchange inlet valve in the direction of flow of a fresh air. A fresh gas line is provided, which opens into the fresh air section after the throttle element, in the region of the at least one gas exchange inlet valve. The fresh gas line opens into the fresh air section via a nozzle, which has flow according to Bernoulli, Venturi or Coanda.

1. A combustion engine, comprising:
at least one cylinder having at least one gas exchange inlet valve and one gas exchange outlet valve; a fuel injection device that injects fuel directly into the at least one cylinder; a fresh air section connectable intermittently for gas transmission to the cylinder via the gas exchange inlet valve; an exhaust section connectable intermittently for gas transmission from the cylinder via the gas exchange outlet valve; a throttle provided in the fresh air section ahead of the gas exchange inlet valve in a flow direction of fresh air; and a fresh gas line which opens into the fresh air section, via a nozzle, after the throttle in a region of the gas exchange inlet valve, wherein the nozzle has a flow according to Bernoulli, Venturi, or Coanda.
