SYSTEM AND METHOD FOR SUPPLYING CLEAN PRESSURIZED AIR TO DIESEL OXIDATION CATALYST

摘要

PROBLEM TO BE SOLVED: To lower the discharge level of undesirable diesel exhaust gas.

SOLUTION: This system for supplying clean pressurized air to a diesel oxidation catalyst (DOC) has a diesel engine 102, a turbo supercharger 104 and the DOC 110. The diesel engine has an outlet for discharging exhaust gas. The turbo supercharger receives at least a first part of exhaust gas and clean air to generate uncooled pressurized clean air. The DOC receives a combination of at least the first part of exhaust gas and at least a second part of uncooled pressurized clean air.
