engineering (including hydraulics) of rolling-stock,
especially of diesel railcars (including heating and air-conditioning
systems), diesel locomotives, and track maintenance vehicles.
analysis of diesel-powered rolling-stock so that railroad
companies in their contracts with manufacturers can stipulate specific
faults to be eliminated and where higher-quality components
are to be fitted. This means that, despite higher first cost, considerably
lower life cycle costs can be achieved (lower maintenance costs,
higher availability etc.).
re-engineering of problem-ridden rolling-stock, especially
of diesel railcars and diesel locomotives.
of existing diesel locomotives and diesel railcars to
new diesel engines (including all necessary alterations
to engine cooling systems and hydraulics).
of existing locomotives and railcars to new air compressors
and their auxiliaries (KNORR-compressors and
-systems), if the old types are no longer available or if the option
of oil-free compressors is wanted. Possible thermal problems
in the original lay-out are identified and eliminated.
- Experimental testing
and engineering/re-engineering of engine and
auxiliary unit suspensions.
of sound transfer from the engine or auxiliary units to the vehicle
structure in order to reduce noise emissions.
of steam locomotives in tourist traffic in order to increase
thermal efficiency and lower running- and maintenance-costs,
including conversion to L. D. Porta's gas-producer combustion
system (GPCS) or the proprietary SePhys oil-firing system.
and manufacture of SePhys burners for special applications
in the use of liquid fuels, e.g. for multiple fuel operation
with extra light (No. 2) heating oil/vegetable oils/waste
of concepts for thermally driven vehicles and thermal
plants including coverage of physical
- General thermodynamic
design- and demonstration-calculations, e.g. for radiator design,
pyrolysis and gasification of municipal solid waste (MSW),
or fire protection.
of engineering concepts of to-be-built and existing vehicles/plants;
assessment of improvement potentials; design calculations;
design and/or selection of components and their installation
in a prototype at the customer's location/workshop in co-operation
with his foremen and skilled workers, if this is wanted; experimental
proof of engineering concepts or improvements and component tests
in both trial runs and regular service. Series production
and series reconstruction can be supported but may also be carried out
under the customer's own management and responsibility.
- Proprietary mathematical model of heat
transfer (both radiative and conductive; including heat dissipation)
from brake discs to wheels, especially important in the case
of radialelastic wheels, i.e. wheels with integrated rubber springs
(this model matches very well experimental values obtained by KNORR-Bremse
- Reduction of noise emissions
from diesel-powered rolling-stock.
- Reduction of smoke emissions
from old diesel locomotives (especially under full-load conditions).
- Onboard emission measurements on diesel
locomotives and diesel railcars in regular service.
