'Clean Diesel has emerged as a prime mover in the Class 6-8 emission reduction market by leveraging its intellectual property in diesel emission reduction technologies, strategic partnerships, and proximity to stakeholders as well as distributors in diesel engine and powertrain technologies,' says Frost & Sullivan Research Analyst David Zhao 'Clean Diesel systems effectively reduce hydrocarbon, particulate matter, and nitrogen oxide (NOx) emissions, enabling truckmakers and powertrain system manufacturers to produce more advanced and efficient vehicles. '
Clean Diesel's exhaust technologies include the combined use of EGR and SCR to reduce NOx emissions in both low and high operating temperatures while maximizing fuel efficiency. Clean Diesel is the first to develop this technology as a viable aftertreatment alternative for the Class 6-8 truck market.
Once seen as competing technologies, Clean Diesel envisioned the combined use of SCR and EGR to meet increasingly strict emissions regulations and address the tradeoff between NOx control and poor fuel economy. The fuel penalty with EGR is well documented with many engine manufacturers including Cummins, Volvo and Detroit Diesel claiming a 3-5% penalty with the use of massive EGR. It also addresses regulator concerns that effective temperatures for SCR operation are typically not achieved during startup or idling. The combined system uses EGR to control NOx during these low-temperature conditions and switches to SCR when the temperature increases and the catalyst is fully active. This overcomes the limitations of each individual technology to provide a system with high NOx reduction for all operating conditions, maximum fuel efficiency and lowest low carbon footprint.
In the area of NOx reduction, the company has also developed expertise in urea and hydrocarbon injection technologies to cost-effectively reduce emissions. Clean Diesel's patented return-flow designs improve reliability and eliminates the need for compressed air, expanding the use of SCR Technologies in moble applications. Its hydrocarbon injection system aids the development of a urea-free SCR technology, helping adopters save thousands of dollars each year in urea-related lifecycle costs.
Clean Diesel looks beyond current emissions regulations scenarios to examine the challenges of emerging regulations on diesels. Such forward thinking regarding regulatory compliance makes Clean Diesel a technology provider of choice for leading power train and after treatment system and module developers. The company's technologies are not only suited to serving the North American market, but also to meeting compliance in global markets.
