Volvo A40D

As a preparation for coming emissions regulations the D12D engine was introduced for A35D and A40D. The D12D engine met US (EPA) step 2, California (CARB) step 2 and Europe (EU) step 2 emission standards. Basic specifications such as power and torque are the same for D12C and D12D engines. The production started in November 2004.

In order to meet the Tier 3 / Stage IIIA legislative demands concerning exhaust emissions, a new version of the Volvo D12 engine was developed for A35D and A40D.

The new engine met US (EPA) Tier 3, California (CARB) Tier 3 and Europe (EU) stage IIIA emission standards.
V-ACT (Volvo Advanced Combustions Technology) was implemented on the D12D engines for the US market only as from April 2005 and the EU market started from January 2006. The Tier 2/Step II compliant D12D engine continued to be available for affected markets.
