DYNTEST Emission Control System for DPF and SCR


Everybody’s talking about saving the environment.
We’re doing something about it. CPK Automotive — your expert partner for
the after treatment of engine exhaust gases. The DynTest System guarantees accurate electronic
controlling and monitoring of the components involved in the treatment of exhaust gases.
And that helps protect our natural resources. It provides a comprehensive solution for heavy
diesel engines. What’s more, it will work with any make of vehicle, and any type of
exhaust system. As well as helping you reduce your running
costs, CPK’s control systems make an active contribution to the protection of the environment.
The DynTest System delivers efficiency at an attractive price.
Diesel particulate filters are highly effective, but they have one drawback: …
… the more soot particles they filter out, the more clogged they become.
Build-ups of backpressure can damage the vehicle engine and the filter.
Swift countermeasures are required to prevent the occurrence of such damage.
The DynTest sensor generates an alarm when the backpressure in the filter reaches a critical
level. An alarm will also be generated when certain preset parameters are met. The driver
(or the person operating the engine) is notified via a display when a critical state is reached.
The sensor generates both an acoustic and an optical alarm.
If required, the RemCo Data Transmission Module can be used to pass on the alarm signal via
a mobile telecommunications network. That means the alarm can be relayed to the Technical
Services Department of the company operating the vehicles. Depending on the system settings,
the alarm message will appear on a screen or on the display of a mobile phone.
In addition, the measurement and alarm data recorded are uploaded to an internet site.
If desired, they can be accessed directly via direct dial-up or mobile phone. Information
about the location of the vehicle and the hours of engine operation can also be retrieved.
The following modules can be integrated in / added to any DynTest system.
CPK’s active and passive regeneration systems are designed to cope with a variety of scenarios. The LiquiCat Add-On Module, for example, guarantees
the precise and correct dosing of additives. The temperature at which diesel particles
ignite can be reduced from 650°C to 350°C by means of an additive, which is mixed with
the diesel fuel. If this initial temperature is maintained
for 1 to 2 minutes, the regeneration process will take place automatically. The reduction
in the ignition temperature will bring about almost complete combustion of the soot particles
trapped in the filter. The CATFire Module actively raises the temperature
of the exhaust gases. In certain operating scenarios, exhaust-gas
temperature levels can be problematic. For example, the temperature of the exhaust gases
generated by municipal buses, rubbish collection vehicles and forklift trucks are seldom as
high as they should ideally be. If the CATFire Module is used in vehicles
of these types,(komplett löschen) atomized diesel fuel is injected into the stream of
exhaust gas, which then mixes with the combustion gases, and is subsequently oxidized by a heat-up
catalyst. The increase in temperature causes the soot
particles to be completely combusted. Like the CatFire, the RegFire Module actively
increases the temperature of the exhaust gases. However, in the case of the RegFire, the temperature
increase is brought about not through the catalysed oxidation of the diesel fuel, but
by combustion. In operating conditions where extremely low
temperatures may be encountered, the RegFire Modules can be installed without any problem.
Further components for the DynTest System are available in the form of the ReCIRC and
the RedNOx systems, which were designed as add-on modules for the denitrification of
exhaust gases. By means of these devices, quantities of the
“cleaned” exhaust gases can be recirculated to aid the combustion process. This reduces
levels of health-threatening nitrogen oxides. Emissions of nitrogen oxides can be significantly
reduced by means of this procedure. We are always interested in working together
with respected scientific institutions. It is our aim to develop products that help preserve
the earth’s finite natural resources. DynTest Control Systems by CPK-Automotive
