THE TECHNOLOGY OF TOMORROW
BEING DEVELOPED TODAY
SEM is an advanced technology centre for ignition
systems. We develop and produce systems for combustion engines along with solenoids, heat exchangers
and sensors for a wide range of application areas.
Our market is global. Our customers include manufacturers of cars and heavy vehicles as well as producers of handheld equipment such as chainsaws and
trimmers. SEM works in partnership with a number
of the world’s leading companies.
Our business is built on long tradition – much has
happened since its founding in 1915. Steady product
development over almost a full century has resulted in
duction solutions from its plants in Sweden and China.

PROFESSIONAL IGNITION SYSTEMS
FOR EFFECTIVE ENGINES
The right ignition system gives the engine the properties needed to perform effectively. In close
conjunction with our customers, we develop professional, dependable systems with long-term
reliability. We currently supply analogue and digital ignition systems to a number of the world’s
leading producers of handheld equipment.
SMALL ENGINE IGNITION SYSTEMS comprise
analogue and digital ignition systems for two- and
four-stroke engines as well as generators.
The ignition system is flexible and can easily be
customised to different applications. A number of
our products are used in tools such as chainsaws,
bush cutters and trimmers, where it features functions
like trip counters, communication and power
to external devices as well as boosted voltage during
low speed sparks.
Our ignition systems are constantly being developed
on the lookout for reliable and user friendly solu-
to improve their functionality and sustainability along
tions that minimise the environmental impact of our
with their environmental footprint. We are always
customers’ engines.
Our ignition systems are flexible
and can with slight changes to
functionality and geometry be
adapted to different applications.

SPECIAL IGNITION SYSTEMS FOR
ALTERNATIVE FUEL ENGINES
Growing environmental awareness in the major cities of the world means vehicles used in
collective traffic are more often using alternative fuel engines. As a result, one of SEM’s fastest
growing product areas is ignition systems for engines run on biogas and natural gas. We
provide customised solutions for heavy vehicles and stationary applications.

Solenoids
QUALITY SOLENOIDS BOOST
PRODUCTION ECONOMY
The combination of Swedish engineering and Chinese production makes SEM solenoids an
attractive alternative in numerous application areas. We work in close partnership with vehicle
and engineering industries throughout the world.
EXTENSIVE EXPERIENCE from the automotive
sector helps us in our development of solenoids. We are
well aware of the specific requirements for end product
functionality, even in harsh application environments.
Solenoids from SEM are primarily used by manufacturers in the automotive and heavy vehicle industry, as well
as by engineering companies. In each of these areas we
can offer quality solutions with excellent production
economy. Our range of products also includes solenoidbased valves.
We are well aware of the specific
requirements for end product functionality, even in demanding environments.

Injector stators
RIGHT STATORS LESSEN THE ENVIRONMENTAL
IMPACT OF DIESEL ENGINES
As environmental legislation becomes stricter, technical solutions to reduce emissions are being
refined. An important component affecting engine emission levels is the injector stator. Intensive
development work, combined with extensive knowledge in the electromagnetic field and ideal
production facilities, enable SEM to offer stators to meet all requirements.
THE STATOR IS A PART of the injection system in
a diesel engine; a vital component that affects engine
effect and environmental impact. High pressure and
rapid response help lower emission levels and reduce
the amount of harmful particles.
Our close working relationships with world leaders in
engine manufacture help keep us in tune with the latest
emission level regulations.
Our combined knowledge of mechanics and electromagnetism means we can develop and manufacture
stators that meet market requirements across the board.

Heat exchangers
THE LAMINOVA HEAT EXCHANGER
Laminova heat exchangers provide outstanding engine and transmission oil temperature control
in the most severe conditions. From high performance racing cars to Paris-Dakar rally cars, you
can rely on Laminova.
Laminova heat exchangers are used as oil coolers to
control engine and transmission oil temperatures, or for
instance the temperature of the power steering system.
Another application is as intercoolers in turbo and supercharged petrol and diesel engines.
Laminova oil coolers are more efficient than the competition due to the unique patented core design. The finned
exterior on the cooler core creates a larger surface area
compared to that of traditional “radiator” style coolers.
The heat exchangers offer both maximum heat transfer
and low pressure drop, something not before possible.
The Laminova heat exchangers are custom designed and
we cooperate closely with designers and OEM-manufacturers world wide.
The small and flexible package is used for both cooling
and heating applications in many different motor vehicles.
