Combustion engine with fresh gas line to increase turbulence

A combustion engine, comprising:

• a cylinder having a gas exchange inlet duct, a gas exchange inlet valve associated with the gas exchange inlet duct, a gas exchange outlet duct, and a gas exchange outlet valve associated with the gas exchange outlet duct;
• a fuel injection device that injects fuel directly into the cylinder;
• a fresh air section connectable intermittently for gas transmission by the gas exchange inlet duct 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;
• an exhaust turbocharger having a turbine in the exhaust section and a compressor in the fresh air section;
• a first throttle provided in the fresh air section downstream of the compressor but ahead of the gas exchange inlet valve in a flow direction of fresh air;
• a fresh gas line, which is taken to a point in the gas exchange inlet duct ahead of the gas exchange inlet valve;
• a second throttle in the fresh gas line setting a cooling rate of fresh air flowing through the fresh gas line;
• and
• a nozzle communicating the fresh gas line with the gas exchange inlet duct at said point, the nozzle opening laterally through a wall of the gas exchange inlet duct into the gas exchange inlet duct, said point being closer to the gas exchange inlet valve than the cylinder;
• wherein the nozzle has a flow according to Bernoulli, Venturi, or Coanda;
• and
• wherein the nozzle is made of metal or plastic.
