Engine recovery system for engine system

An engine system comprising:

• an engine;
• an exhaust conduit configured to receive exhaust gases discharged from the engine;
• a first turbocharger coupled to the exhaust conduit to receive exhaust gases from the engine and configured to provide compressed air to the engine;
• a bypass conduit coupled to the exhaust conduit upstream of the first turbocharger,
• the bypass conduit facilitating a portion of the exhaust gases from the exhaust conduit to bypass the first turbocharger;
• a second turbocharger coupled to the bypass conduit,
• the second turbocharger being driven by the portion of the exhaust gases bypassing the first turbocharger to compress air received from an ambient to a first pressure;
• a bypass valve to control an amount of the portion of the exhaust gases passing through the bypass conduit to the second turbocharger,
• the bypass valve being controlled based on a maximum capacity of the first turbocharger;
• and
• an accumulator in fluid communication with the second turbocharger and configured to store air received from the second turbocharger at the first pressure.

A locomotive comprising:

• an engine;
• an exhaust conduit configured to receive exhaust gases discharged from the engine;
• a first turbocharger coupled to the exhaust conduit to receive exhaust gases from the engine and configured to provide compressed air to the engine;
• a bypass conduit coupled to the exhaust conduit upstream of the first turbocharger,
• the bypass conduit facilitating a portion of the exhaust gases from the exhaust conduit to bypass the first turbocharger;
• a second turbocharger coupled to the bypass conduit,
• the second turbocharger being driven by the portion of the exhaust gases bypassing the first turbocharger to compress air received from an ambient to a first pressure;
• a bypass valve to control an amount of the portion of the exhaust gases passing through the bypass conduit to the second turbocharger,
• the bypass valve being controlled based on a maximum capacity of the first turbocharger;
• an accumulator in fluid communication with the second turbocharger and configured to store air received from the second turbocharger at the first pressure;
• an auxiliary compressor fluidly coupled to the accumulator, and configured to compress air received from the accumulator to a second pressure;
• and
• an air reservoir configured to store the air received from the auxiliary compressor at the second pressure.
