Cat reveals EU Stage IV solution at INTERMAT
C7.1 and C13 engines get SCR after-treatment for emissions
Caterpillar announced its EU Stage IV emissions solution at INTERMAT for C7.1 and C13 industrial engines.
With power ratings from 116kW to 225kW, the 7.1litre six-cylinder C7.1 gets an SCR catalyst and diesel exhaust fluid dosing system as part of the exhaust after-treatment process.
The larger C13 – 13litre, 287-387kW power sector – also gets an SCR and diesel exhaust fluid after-treatment system, but retains its active regeneration process. Both engines have been proven to have a total fluid consumption – diesel fuel and diesel exhaust fluid – of up to 5% less than their Stage IIIb predecessors.
