Jacob Vehicle Systems has positively responded to the California Air Resources Board’s (CARB) new emission reduction strategies.
Posted on the CARB website on 23 June, the new amendments will be discussed at a public meeting on 27 August. The projected emission rule will require HGVs still reliant on fossil fossils to have the most effective emission-control technologies currently available, in a bid to limit nitrogen oxide and particulate emissions.
Jacobs is a global manufacturer of diesel and natural gas retarding systems and valve actuation mechanisms. Currently, the company is involved in numerous emission-reduction development and demonstration projects on commercial vehicle powertrains around the world.
CARB’s newly proposed amendments include:
- A proposal to reduce the current heavy-truck NOx standard from 0.20 grams per brake horsepower-hour to 0.050 g/bhp-hr from 2024 to 2026, and even lower to 0.020 g/bhp-hr in 2027.
- A bid to reduce heavy-truck particulate matter emissions from its current emission standard of 0.01 g/bhp-hr to a standard of 0.005 for 2024 and subsequent model-year engines.
Recent tests have concluded that Jacobs’ cylinder deactivation (CDA) engine systems can deliver better fuel economy, while keeping diesel exhaust after-treatment systems operating at optimal temperatures. This strategy upholds proposed goals of reducing nitrogen oxide (NOx) within the CARB HD Omnibus and the EPA Clean Trucks Initiative (CTI) along with lowering CO2 emissions sought by the EPA GHG Phase 2 requirements.
Jacobs’ cylinder deactivation engine systems can deliver better fuel economy, while keeping diesel exhaust after-treatment systems operating at optimal temperatures, recent tests have shown. The company is working towards the goal of reducing nitrogen oxide (NOx) within VARB HD Omnibus and the EPA Clean Trucks Initiative. Moreover, this contributes towards lowering CO2 emissions, as encouraged by the Environmental Protection Agency’s regulations for Greenhouse Green Emissions from Commercial Trucks and Buses.
‘Jacobs has been working with customers and industry partners for years to develop solutions to improve engine combustion and after-treatment efficiency to be ready to respond to these new regulations’, said Steve Ernest, vice president of engineering and business development for Jacobs. ‘We have the technology to help engine and vehicle makers meet these new limits and improve fuel efficiency while doing it’.
