In-Service Emissions from Model Year 2012 Hydraulic Hybrid and Model Year 2008 Conventional Diesel Package Delivery Trucks

2015

In-service emissions measurements were conducted on two package delivery trucks: one model year 2008 FCCC MT-55 conventional diesel and one model year 2012 FCCC MT-55 hydraulic hybrid (HHV). Mass emissions of CO₂, CO, NO_x, PM, and THC from the HHV and the conventional diesel test vehicle were each measured under conditions closely simulating normal package delivery operation.
