problem health issues

Diesel Particulate Matter (DPM) emissions cause significant health problems

    • Diesel fumes known carcinogen (W.H.O. 2012)
    • Submicron, nano-sized particulates cause respiratory problems.
    • Exposure of underground miners to DPM is the highest among all occupations (Cohen et al., 2002)
Problem: Health Issues

problem emissions regulations are oem business concern
Problem: Emissions Regulations are OEM Business Concern

From most recent 10-K (annual financial report) filings…

“[O]urability to comply with other existing and future regulatory standards will be essential for us to maintain our position in the engine markets we serve.”

United States Environmental Protection Agency (EPA) off-road diesel Tier 4 regulations: effective 2013

“The level of market acceptance of prices for products that meet Tier 4 requirements could negatively impact our financial results and competitive position”

“[Changes] in emissions standards resulted in a significant increase in the cost of our products to meet these emissions levels.”

EU off-road diesel Stage IV regulations: effective 2014

Stage IV and Tier 4 data from: http://www.dieselnet.com/standards

problem current technologies don t cut it

Current technologies are expensive and inefficient

    • Expensive filters need regular maintenance and can only operate in a limited temperature range
    • Backpressure caused by filters can cause up to a 10% increase in fuel consumption.
    • Trade off between PM and NOx emissions levels
    • Current electrostatic precipitation (ESP) technologies have efficiency minima for nano-sized particles.
