Position the analyzer as high as possible with the tubing leading to the
probe running continuously downhill.
Observe the usually translucent tubing between the probe and the
analyzer and be sure no water is ingested. If any water is ingested into
the analyzer, it must be repaired or replaced and recalibrated.
When measuring CO at the exhaust outlet be aware of the ambient CO
level by also measuring CO away from and upwind of the exhaust
outlet, especially in marinas. The CO level at the exhaust outlet will be
influenced upwards by the ambient level.
Whenever taking the time to verify proper CO concentration from the
exhaust with a CO analyzer, always use the analyzer to sniff around the
engine looking for CO from exhaust leaks. Pay close attention to the
connection of the cylinder head to the exhaust manifold, the exhaust
manifold to the water-injected exhaust elbow, and all subsequent
downstream exhaust components and hoses.
Exhaust gas that has not yet passed through the catalyst is raw,
untreated, and very high in CO content.
Analyzers usually require periodic calibration. Follow the instructions
that come with the analyzer very carefully regarding calibration.
The following manufacturers offer CO analyzers: Extech, TIF, Testo, TSI,
Bacharach, Fluke, Monoxor, Fyrite, Zellweger Analytics, Industrial
Scientific, GFG, TPI, Teledyne, and others.
Westerbeke recommends analyzers with a probe connected to the
analyzer by a length of transparent tubing. They are slightly more
expensive than those with the sensor built-in to one end of the analyzer,
but they allow you to sample the exhaust coming out of the boat
exhaust outlet.
California Exhaust Emissions Standards
This genset meets the requirements of the California Exhaust Emissions
Standards as stated on the nameplate. California users of this genset should
be aware that unauthorized modifications or replacement of fuel, exhaust,
air intake, or speed control system components that affect engine emissions
are prohibited. Unauthorized modification, removal or replacement of the
engine label is prohibited.
Federal Emissions Compliance Period
The Federal Emissions Compliance Period referred to on the nameplate
indicates the number of operating hours for which the engine has been
shown to meet Federal Emissions requirements:
Category A = 1000 hours
Category B = 500 hours
Category C = 250 hours
Carefully review operator, installation, and other manuals and
information you receive with your genset. If you are unsure whether
the installation, use, maintenance, or service of your genset is
authorized, seek assistance from an approved Westerbeke dealer.
California genset users may use the table below as an aid in locating
information related to the California Air Resources Board emissions control
requirements.
