The cleaner engine is able to deliver ultra-low NO x by managing exhaust gas temperatures to ensure rapid catalyst light-off and by maintaining aftertreatment temperatures at optimum operating conditions in all driving conditions. It is expected to cost less than current engines, even as it meets much more stringent environmental regulations.
