US 2014/0338310 A1 · METHOD, APPARATUS, AND SYSTEM FOR OPTIMIZING EXHAUST BACKPRESSURE OF INTERNAL COMBUSTION ENGINE

Abstract

A method for optimizing exhaust backpressure of an internal combustion engine, comprising the following steps: 1) arranging a damping component in an exhaust passage of the internal combustion engine, and allowing an exhaust discharged by the internal combustion engine to pass through the damping component; and 2) allowing the exhaust to be cooled prior to passing through the damping component, or allowing the exhaust to be cooled while passing through the damping component. The method allows for relatively high exhaust backpressure when the internal combustion engine has a low load, and for preventing the exhaust pressure from rising excessively rapid when the internal combustion engine has a heavy load. The apparatus and system for optimizing exhaust backpressure of an internal combustion engine is also provided.

A method for optimizing exhaust backpressure of an internal combustion engine, comprising:

1) providing a damping member in an exhaust passage of an internal combustion engine, and making exhaust gas discharged from said internal combustion engine passing through said damping member;
2) cooling the exhaust gas before passing through said damping member, or cooling the exhaust gas while passing through said damping member.
