Latest C7.1 engine meets Tier 4 Final/Stage IV using SCR

Caterpillar’s industrial engines division is using the C7.1 as a common engine platform as a replacement for the C6.6 as it meets Tier 4 Final/Stage IV emissions regulations. It means the 7.1litre six-cylinder C7.1 offers power ratings from 116kW to 225kW in either single turbo or series turbo configurations, and adds an SCR catalyst and diesel exhaust fluid dosing system as part of the existing exhaust after-treatment process.

At Tier 4 Final/Stage IV, the C7.1 offers a 5% total fluid consumption gain over its Tier 4i/Stage IIIb counterpart.
178 Caterpillar’s industrial engines division is using the C7.1 as a common engine platform as a replacement for the C6.6 as it meets Tier 4 Final/Stage IV emissions regulations.

It means the 7.1litre six-cylinder C7.1 offers power ratings from 116kW to 225kW in either single turbo or series turbo configurations, and adds an SCR catalyst and diesel exhaust fluid dosing system as part of the existing exhaust after-treatment process.

This revised emissions control system is now passive – previous versions of the C7.1 engine used a DPF with active regeneration system – and this latest version is said by Cat to have no impact on machine operation.
Cat said this latest C7.1 engine has been proven to have a total fluid consumption – diesel fuel and diesel exhaust fluid – of up to 5% less than its Tier 4i/Stage IIIB predecessor.

Stand: A4, 316
