engine calibrations, such as fuel output settings, injection
timings, emission control device calibration and location,
charge air and cooling system calibration and location are
prohibited from any alterations from the certified
configurations.
Provisions of the Clean Air Act also prohibit any persons,
including but not limited to, Dealers or Body Builders to
remove or render inoperative any devices or elements of
design installed in a motor vehicle engine in compliance
with the regulations. Please refer to Section 8 Exhaust
System for further information.
1.3.2 Vehicle Noise Emission
Control Information
The Noise Control Act of 1972 and the 40 CFR Part 205
U.S. EPA regulations, "Transportation Equipment Noise
Emission Controls", require new medium and heavy
trucks over 10,000 lbs. GVWR to comply with an exterior
drive-by noise standard of 80 dB(A). In Canada, CMVSS
1106 Noise Emissions Standard requires an additional
interior sound level certification at 90 dB(A). All Sprinter
vehicles now offered in the NAFTA market are rated at
below 10,000 lbs. GVWR. Some future Sprinter vehicles
may be rated above 10,000 lbs. GVWR, thus, they will be
subject to these noise certification requirements with the
vehicle noise emission label affixed. Nevertheless, all
Sprinter vehicles come equipped with extensive
applicable noise control packages, which were tested at
over 100% reduction in noise levels below the
aforementioned noise standards. Final Stage
Manufacturers should consult with their attorney
concerning the compliance of their vehicles with
appropriate regulations and laws, once they are altered or
modified.
The law and regulations prohibit tampering with noise
control devices or components. Specifically, the removal
or rendering inoperative of any devices or elements of
design incorporated into any new vehicle for the purpose
of noise control is not permitted. Such devices or elements
are identified as noise emission related components, such
as engine calibrations including governor settings,
exhaust system components, air induction system
components, radiator shield, fan/drive, noise shields or
acoustical absorptive material, etc. The regulations also
require maintenance of the noise control performance in
use, to comply with the U.S. EPA 40 CFR Part 202, or
DOT 49 CFR Part 325, Exterior Drive-By Noise Emission
Standards for Interstate Motor Carrier.
1.3.3 Vehicle Safety Standards
Information
In the U. S., National Traffic and Motor Vehicle Safety Act
of 1966 and NHTSA’s FMVSS regulations and in Canada,
Motor Safety Act of 1993 and Transport Canada’s (TC)
