The
goal of this contract is to demonstrate a retrofit system for marine
vessels which is intended to bring Tier 0 marine engines up to Tier 4
standards with the combination of Compact Selective Catalytic Reduction
(SCR) systems and diesel particulate filters (DPF). Engine, Fuel,
and Emissions Engineering, Inc. (EF&EE) has supplied Compact
SCR(tm) systems for six vessels based in San Francisco: totalling 12
systems for the vessel main engines and two for generators.
These systems are now operating satisfactorily. When installed on
modern Tier 2 diesel engines, the Compact SCR system alone can easily
achieve Tier 4 NOx emissions, and can approach Tier 4 PM levels.
This project is applying a combination of Compact SCR and diesel
particulate filters to the main propulsion and genset engines of M/V
Royal Star. These are typical Tier 0 engines—built before
emission standards were adopted. The goal of this
installation is to reduce the NOx and PM emission levels from these
engines to within Tier 4 standards.
Christopher Weaver,
P.E., is
the founder and President of Engine, Fuel, and Emissions Engineering,
Inc., (EF&EE) Sacramento, California. He is
an automotive
engineer with more than 25
years of experience in the areas of internal combustion engine
technology, fuels, combustion, emissions, and emission controls. His
recent work has focused on vehicle emissions measurement, alternative
fuels such as natural gas and ethanol, and post-combustion emission
control systems such as diesel particulate filters and SCR.
Mr. Weaver is the inventor of EF&EE's patented "ride along"
emission sampling system (RAVEM), providing the functionality of an EPA
emission laboratory in a portable, cost-effective package. He has
designed and managed emission testing programs on three continents, for
vehicles ranging from passenger cars and buses to locomotives and ferry
boats. He is currently directing projects to demonstrate
EF&EE’s Compact SCR™ technology on trucks, locomotives,
ferryboats, and other non-road equipment.
As a consultant to the U.S. EPA during the 1980s, Mr. Weaver played an
important role in the establishment of heavy-duty diesel emissions
standards, sulfur and aromatic limits on diesel fuel, and the phase-out
of leaded gasoline in the U.S. A preliminary study of emissions control
for off-highway vehicles for EPA led to the inclusion of regulatory
authority over such vehicles in the 1990 Clean Air Act amendments. More
recently, Mr. Weaver served as an expert witness for the Justice
Department in its landmark "defeat device" case against the major
heavy-duty diesel engine manufacturers, and directed studies to assess
technology for the proposed 2004 and 2007 heavy-duty engine emission
standards.
As a technical consultant to the World Bank, Mr. Weaver played an
important part in designing the Mexico City Transport Air Pollution
Control Program, as well as similar efforts in Bangkok, São Paulo,
Santiago de Chile, Buenos Aires and Colombo. He was one of three
foreign experts contracted to advise the Bhure Lal committee appointed
by the Indian Supreme Court to assess the court-ordered implementation
of CNG buses and related control measures in Delhi. He has made
substantial contributions to the worldwide phaseout of leaded gasoline
– most recently, as the author of the "Implementer's Guide to Phasing
Out Lead In Gasoline" distributed worldwide by the U.S. EPA and U.S.
AID. Since 2004, he has served as an advisor to the U.N. Commission on
Regional Development as a member of its expert panel on environmentally
sustainable transport (EST).
Mr. Weaver was a senior engineer and project manager at Sierra Research
for three years before leaving to form EF&EE. During this time,
he also taught a post-graduate course in motor vehicle emissions and
their control at Santa Maria Technical University in Chile. He was
previously Group Leader of the Automotive Engineering and Emissions
Control Group at Radian Corporation, and Director of Engineering at
Energy and Resource Consultants. He holds a B.S. degree in Mechanical
Engineering from Berkeley, with a minor in economics, and an M.S. in
Mechanical Engineering from MIT. He is the author of more than two
dozen technical papers and co-author of two books in the field of
mobile-source emissions and their control.
