Internal combustion engine with dual particulate traps ahead of turbocharger

A method of operating an internal combustion diesel engine including a plurality of combustion cylinders, comprising the steps of:

• filtering particulates from a first set of combustion cylinders using a first particulate trap in communication between the first set of combustion cylinders and a turbocharger;
• filtering particulates from a second set of combustion cylinders using a second particulate trap in communication between the second set of combustion cylinders and said turbocharger, and
• independently and selectively controlling the fluid flow through said first and second set of combustion cylinders by increasing a fuel rate to one set of combustion cylinders by an amount sufficient to regenerate the particulate trap associated with the set of combustion cylinders receiving the increased fuel rate and decreasing a fuel rate to the other set of combustion cylinders.
