The Importance of Emissions Testing

Throughout the EcoCAR 2 competition, students work with donated production vehicles to improve their energy efficiency and to meet the toughest emissions standards, while maintaining performance, consumer acceptability and safety. Extensive data is collected to measure the real-world performance of the advanced technologies and benchmark their developmental status. In addition to battery electric, teams utilize different fuels like E85 (ethanol), B20 (biodiesel), and hydrogen.

To test and analyze the vehicle’s improvements to fuel efficiency, student vehicles will take part in the Emissions & Energy Consumption (E&EC) event. The E&EC event is a compilation of four different emissions tests at the Year Three Competition. These tests measure the mass of liquid fuel consumed during the trip modally by using the SEMTECH emissions equipment and carbon counting, and the total mass of fuel for the trip will be validated by comparing the starting and finishing liquid fuel tank masses. The event also calculates for petroleum energy use, criteria emissions, and well-to-wheel greenhouse gas emissions, and is worth more than 300 out of the 1,000 points in the Year Three Competition.
