Document Type and Number:
Japanese Patent JP2002508472
Kind Code:
A
Abstract:
Internal combustion engines are described including a crankshaft and at least one cylinder, an intake line for supplying air to the cylinder, an exhaust line for discharging exhaust gases from the cylinder, a recirculation line for recirculating at least a portion of the exhaust gases from the exhaust line to the intake line in order to reduce emissions from the engine, a valve in the recirculation line for controlling the flow of a portion of the exhaust gases therethrough, a turbocharger including a first turbocharging unit for absorbing energy from the exhaust gases and including a compressor to compress air supply to the intake line, and a second turbocharger unit disposed downstream of the first turbocharger unit for absorbing energy from the exhaust gases whereby a pressure is created in the exhaust line which is greater than the pressure in the intake line, and a power transmission line for transmitting power from the second turbocharger unit to the crankshaft. Methods for reducing emissions from internal combustion engines are also disclosed.
