Internal combustion engine with choke has turbine in choke bypass and another arrangement that make some of the energy of the air sucked into the engine reusable by the engine

摘要

The internal combustion engine has a choke (2) in its induction air channel (1) for controlling the engine, a bypass (11) around the choke and a turbine (6) in the bypass. Some of the energy of the air sucked into the engine is made reusable by the engine by the turbine in the bypass and another arrangement (8). The bypass has one or more chokes for optimizing defined engine operating states.
