Power management company Eaton offers products to help heavy-duty vehicles meet the potential new Environmental Protection Agency emission regulations recently outlined in the organization’s Advance Notice of Proposed Rule on emission standards. The ANPR, released on January 6, 2020, describes plans to establish new emission standards for nitrogen oxide and other pollutants for highway heavy-duty engines. It also details opportunities to streamline and improve certification measures to reduce costs for engine manufacturers. This proposal is part of the EPA’s Cleaner Trucks Initiative, which Eaton publicly announced its support for in 2018.

Eaton’s Vehicle Group has developed several innovative technologies that reduce both NOx and carbon dioxide emissions in commercial and passenger vehicles, and recently proved in existing and proposed regulatory test cycles that its cylinder-deactivation CDA technology is a cost-effective path to simultaneously reduce both types of emissions.

Tests of the CDA technology conducted on heavy-duty diesel engines by the Southwest Research Institute (SwRI) in San Antonio, Texas, resulted in an up to 86 percent NOx reduction and three to eight percent CO2 reduction, depending on the test cycle. The results, which show similar levels of real-world fuel economy improvement, are representative of the new low-load in-use compliance regulations.

Additional products that will meet forthcoming emissions standards include Eaton’s new TVS® EGR pump, which is a key enabler for novel high-efficiency turbocharging techniques that lower engine pumping losses and increase fuel economy.

Additionally, Eaton’s eMobility business provides zero-emissions solutions for electrified vehicles, including intelligent power electronics, power systems, and advanced power distribution and circuit protection technologies.
