Regulations like California's recent Advanced Clean Trucks rule, which calls for every new truck sold in the state to be zero-emission by 2045, will drive increasing development and sales of battery-electric and hydrogen-fuel-cell commercial vehicles. Diesel engine and aftertreatment technology will continue to become cleaner - and more complex - to meet the call for lower emissions in the intervening years.
According to Joshua Israel, market development manager, Horiba Automotive Test Systems, the trends toward increasing powertrain diversity and converging regulations for NOx, greenhouse gas (GHG) and on-board diagnostics (OBD) compliance can prove challenging for heavy-duty engine and commercial-vehicle (CV) development and certification. For example, advanced aftertreatment solutions likely will increase the number of failure modes and components to test, and fuel-saving technologies such as cylinder deactivation and waste-heat recovery are expected to drive up OBD development and testing costs. Israel recently spoke with TOHE to discuss this increasingly complex development landscape.
