Hybrid drive operating method for e.g. petrol engine of e-vehicle, involves sucking air present under pressure and developed from operating cylinders, and regulating pressure in suction tract depending on engine operating condition

摘要

The method involves driving operating cylinders (11a, 11b) by compressed air in a compressed air hybrid engine, and driving combustion cylinders (2-5) by a fuel. Air present under pressure and developed from the operating cylinders is guided into a suction tract (6) and sucked as compressed fresh charge from the combustion cylinders cooled during pressure decompression and/or pressed into the combustion cylinders. Pressure in the suction tract is regulated using a controlled pressurizing device (9) depending on an engine operating condition. An independent claim is also included for a hybrid drive operating device comprising a controlled pressurizing device.
