摘要： A turbocharger having an electric motor for assisting spin up of the rotor employs a shaft carrying the turbine and compressor impeller with a unitary pinned semi-floating bearing supporting the shaft and a spacer collar carrying the electric motor magnet. The unitary bearing has integral thrust faces engaging a hub of the turbine wheel and the spacer collar. A reduced diameter of the shaft received in the spacer collar allows the collar to engage a greater diameter bearing land allowing the attachment of the compressor impeller with a nut on the shaft extending through a bore in the impeller to firmly engage the impeller, spacer collar and bearing land of the shaft to fix the rotor length. The pinned semi-floating bearing with integral thrust faces provides enhanced reaction moments for negative spring forces created by the electric motor in operation and the additional length of the rotor created by the motor.

摘要： An internal combustion engine has an exhaust gas turbocharger with an exhaust gas turbine and a compressor. In addition, an air-driven turbine is provided which is torsionally connected to the compressor and to which combustion air can be supplied via an adjustable shut-off element. For operation of the exhaust gas turbocharger over a wide operating spectrum, an additional duct is provided between compressor inlet and the air inlet of the air turbine, the air supply in the additional duct being adjustable by the shut-off element. In the lower load range, in the case where the required boost pressure falls below a threshold value, the additional duct is opened by means of the shut-off element and the air supply to the compressor inlet is reduced.

摘要： A low pressure EGR system suitable for use as a passive retrofit system is disclosed for moving vehicles equipped with a diesel engine. The EGR loop inlet is positioned upstream of the exhaust particulate filter and downstream of the turbine to utilize backpressure created by the exhaust particulate filter to insure EGR flow in the loop. A catalyzed soot filter in communication with the EGR pickup insures cleansed EGR gases at the EGR return downstream of the air filter and upstream of the compressor. A corrugated EGR line provides cooling of the EGR gases.

摘要： An apparatus (11) for controlling the peak pressure in the combustion chamber (46) of a turbo-charged diesel locomotive engine (12). A pressure relief valve (56) is disposed in the compressor discharge downstream of the turbo-charger (18). The relief valve (56) is operable to release a selected amount (58) of the compressed air (24) produced by the compressor section (20) of turbo-charger (18). The actuation of valve (56) may be a function of the pressure of the compressed air (24), and/or a manifold air temperature signal (52) and a fuel injection timing signal (40). An actuator (60) attached to valve (56) is responsive to a valve position signal (62) generated by a controller (38) having the appropriate inputs and programmed logic capability.

摘要： A charge air condensation separation system for a turbocharged engine, especially suited for engines employing EGR, includes a turbocharger having a compressor providing charge air with a charge air cooler connected to the compressor to cool the charge air. A charge air delivery duct is connected to an outlet of the charge air cooler and a torroidal trap having an annular inlet is disposed in the charge air delivery duct with a sump for collecting condensation integral to the torroidal trap. A drain line for removing condensation from the sump for expulsion to the atmosphere is connected to the trap and a pump or other device for overcoming pressure differential in the drain line is employed in certain embodiments. For EGR systems employing a mixer, the condensation separator can be incorporated adjacent to or integral with the mixer to minimize additional volume requirements in the engine compartment.
