The Air Resources Board has conditionally verified the Cleaire Lonestar diesel retrofit system for certain 1996 through 2009 model year diesel engines in rubber-tired off-road vehicles.  The Lonestar reduces emissions of diesel particulate matter by at least 85 percent and is designated as a Level 3 plus system.  The Lonestar also reduces emissions of oxides of nitrogen (NOx) by 40 percent.  The primary components of the Lonestar include a catalyzed silicon carbide wall-flow filter and a lean NOx catalyst.  The Lonestar system is compatible with off-road vehicles using diesel fuel that contains up to 20 percent biodiesel.  Specific conditions for which the Lonestar system has been approved may be found in the conditional verification letter below.
