Abstract: A control for a turbocharger system in an internal combustion engine particularly useful for multiple parallel turbochargers having turbines with discrete step variable nozzles. In response to a need for adjustment the variable nozzles are adjusted sequentially, not simultaneously. Sequential adjustment of the turbines minimizes the impact of the adjustment.

Abstract: A turbine impeller to be driven for rotation by exhaust gas of an internal combustion engine is fixed to a turbine shaft. The turbine shaft is supported by a radial bearing in radial directions and mounted to a bearing housing. The turbine shaft includes a stepped part which is formed between the turbine impeller and the radial bearing so that the outer diameter of the turbine shaft is greater at the turbine impeller side than at the radial bearing side. The bearing housing includes an oil drain for discharging oil which has lubricated the radial bearing. The distance L from a side face of the radial bearing to the stepped part is set to a value at which oil moving from an end of the radial bearing does not reach the stepped part when a turbine-revolution speed Nt is higher than that Nti which is produced by an idling operation of the internal combustion engine.

The interstage duct includes a bypass opening includes in communication with an ambient environment. A valve is positioned within the interstage duct. The valve is moveable to and between a first position to close the interstage duct and a second position to close the bypass opening.

Abstract: In an internal-combustion engine (1) of the Otto type, in which exhaust gases are used in order to drive a turbocompressor (14, 15) for supercharging the engine, the engine is designed in such a manner that it can, at high load, be run with a lean mixture during supercharging, the air/fuel ratio being at least 19:1. The lean mixture is brought about by virtue of the fact that the charging pressure increases while the fuel quantity is maintained. The engine is advantageously provided with a divided exhaust-gas discharge in order to improve the operating characteristics.

Abstract: An enhanced bearing system for turbochargers incorporates a thrust collar centrally mounted on the rotating shaft interconnecting the turbine and compressor and a thrust bearing centrally located within the center housing to constrain the thrust collar.

Abstract: The method for turbocharging an engine of a locomotive in which the engine is operable at a plurality of discrete operating power levels includes controlling at least one of energy to a motor-assisted turbocharger at a plurality of discrete energy levels and air pressure from the motor-assisted turbocharger to the engine at a plurality of discrete air pressure levels above ambient air pressure based on at least some of the plurality of discrete operating power levels (e.g., low power levels) of the engine. Desirably, the method also includes controlling generation of electrical energy from the motor-assisted turbocharger at some of the plurality of discrete operating power levels (e.g., high power levels) of the engine. Apparatus for turbocharging a diesel engine of a locomotive incorporating the above methods are also disclosed.

Abstract: A device for limiting the supercharger speed which makes do without a speed sensor or an atmospheric pressure sensor has a bandpass filter which filters out a spectral component from the output signal of a boost pressure sensor arranged in the induction pipe of the engine, the spectral component appearing in the signal spectrum of the boost pressure sensor when the air column in the induction pipe is set into a vibration which develops when the compressor of the turbocharger rotates at the maximum permissible speed.
