Analysis of the Fuel Economy and Carbon Dioxide Emissions of a Heavy-Duty Vehicle in Part of a Driving Cycle | Chapter 10 | Research Developments in Science and Technology Vol. 8

A heavy-duty vehicle's fuel efficiency and carbon dioxide emissions are investigated in relation to the weight it is carrying, the slope of the road it travels on, and its speed. In the course of a driving cycle, a heavy-duty vehicle provides these final two variables. The heavy-duty vehicle weighs 14.742 tonnes empty, has a 10-gear transmission, and an engine with a maximum torque and power of 2100 Newton metres and 455.261 horsepower, respectively. The driving cycle is one method the US Environmental Protection Agency employs to electronically verify the fuel efficiency and carbon dioxide emissions of heavy-duty vehicles. There are two scenarios that are examined. In the first, a truck is hauling a 15-ton weight along a straight route. In the second case, the car is hauling a 25-ton weight while travelling down a 2° incline. The forces acting on the vehicle are first computed. The required engine torque to drive the vehicle is then obtained, and ultimately, the fuel use, fuel efficiency, and carbon dioxide emissions are assessed. The authors' computer software, UAMmero, is used to calculate the results. The investigation led to several suggestions for how to operate a heavy-duty truck more efficiently and with lower carbon dioxide emissions.
