The engine has a charging fan (31) that is disposed upstream of and in series with a compressor of one of number of exhaust-driven superchargers (14-16), and a motor (34). Each supercharger has a line connection via a respective valve mechanism to an outpu...

The turbo-charging control system is such that at low flow rate, a first turbo-compressor (10) operates, and at high flow rate two turbo-compressors operate. The output gases from the turbines pass through pollution control chambers and catalysers, reducin...

A vehicle system controls a compression ignition internal combustion engine equipped with a supercharger system including a plurality of superchargers. The compression ignition internal combustion engine has an exhaust gas recirculation (EGR) system. The v...
