Abstract
A particularly efficient and reliable motor-assisted turbocharger for internal combustion engines includes an assisting electric motor, a combination flow turbine wheel which may be inserted and removed from the turbocharger assembly through the exhaust opening of the turbine casing, and a divided volute turbine casing designed in a unique way so that the tips of the turbine blades can be extended to be closely adjacent to the turbine casing divider wall without complicating the mechanical design of the turbine, thereby providing an economical assembly with high-turbine efficiency compared with conventional, radial turbines used in turbochargers, and by providing in preferred embodiments, improved bearing support for the shaft, including reliable, stable shock- and vibration-resistant, high efficient, simple and economical bearing systems that are insertable and, permit inexpensive manufacture, maintenance, and repair of the turbochargers in which they are used.
