摘要： Various systems are provided for an axially split turbocharger case housing each of a turbine of a turbocharger, a compressor of the turbocharger, and a bearing of the turbocharger. In one example, an apparatus for an engine includes a first monolithic component and a second monolithic component that, when coupled together, form a turbocharger case configured to house each of a turbine, a compressor, and a bearing, the first and second monolithic components, when coupled together, also forming a compressor shroud and a turbine shroud. In further examples of the system, portions of the turbocharger case are formed of a lattice structure.

摘要： Methods and systems are provided for an electric turbocharger (e-turbo). In one example, a method may include monitoring an e-turbo parameter or an engine parameter, comparing the monitored e-turbo or engine parameter to a determined threshold value for the e-turbo or engine parameter, and signaling a status of the e-turbo in response to the monitored e-turbo or engine parameter differing from the determined threshold value by at least a threshold amount.

摘要： Various systems and methods are provided for adjusting operating parameters of an internal combustion engine. In one example, a system may include adjusting an amount of advance of a fuel injection timing of a plurality of fuel injectors of an internal combustion engine relative to top dead center (TDC) responsive to engine output demand, where, as the engine output demand increases, the amount of advance first decreases and then increases. In this way, an amount of vehicle emissions may be decreased while an amount of fuel consumption is decreased.

摘要： Methods and systems are provided for controlling a power output of a power source using a fluidic variable turbine turbocharger. In one example, a turbocharger system coupled to the power source includes a first turbocharger having a first compressor and a first turbine, and a second turbocharger having a second compressor and a second turbine, where boost air from the second compressor is directed to only a nozzle of the first turbine.

摘要： Methods and systems are provided for electric turbochargers. In one example, a turbocharger comprises a shaft coupling a compressor wheel to a turbine wheel, an electric machine including a stator encircling the shaft between the compressor wheel and the turbine wheel, and an oil supply passage formed in a housing of the electric machine and fluidly coupled to a first oil nozzle oriented toward the shaft.

摘要： Various systems are provided for a single turbocharger case housing each of turbine of a turbocharger and a bearing of the turbocharger. In one example, an apparatus for an engine includes an integrated, monolithic turbocharger case that houses each of a turbine and a bearing of a turbocharger and a nozzle ring integrated into the turbocharger case between the turbine and the bearing. In further examples of the system, portions of the turbocharger case are formed of a lattice structure.
