PROFESSIONAL IGNITION SYSTEMS FOR EFFECTIVE ENGINES

Small engine ignition systems

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

to improve their functionality and sustainability along

with their environmental footprint. We are always

on the lookout for reliable and user friendly solu-

tions that minimise the environmental impact of our

customers’ engines.

Our ignition systems are flexible and can with slight changes to functionality and geometry be

adapted to different applications.

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.

SPECIAL IGNITION SYSTEMS FOR ALTERNATIVE FUEL ENGINES

ENVIRONMENTAL ISSUES have high priority around

the world. Technical solutions to minimise environmental

impact are making steady progress in most fields.

SEM has for many years delivered ignition systems for

natural gas vehicles in the US where authorities were

early in setting tough demands for emission levels.

We also deliver ignition systems for stationary

engines that run on fuels like natural gas and biogas.

The engines are used in applications such as electricity

production – a fast growing market.

The products are often used in applications where a high

level of uptime is expected.

Proprietary technology for monitoring and diagnostics

enables SEM to meet tough application requirements.

With the use of ion current sensing, using only the

spark plug as a sensor, we can provide a number of

diagnostic tools.

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.

PRACTICAL APPLICATION PROVIDES INVALUABLE EXPERIENCE

SEM’s car ignition system has been on the market for over 20 years. This long practical experience

has given us invaluable knowledge that we are happy to share.

SEM IS ONE OF THE DEVELOPERS behind the

ignition system for SAAB Automobile, one of the most

advanced systems on the market with unique functionality.

Besides effective ignition, the system has functions for

individual timing, knock detection and poor combustion

measuring using ion sensing in every cylinder.

The years of practical experience and continuous develop-

ment have formed knowledge base for the coming genera-

tions of ignition systems, and have enabled us to collect

detailed information from ion sense signals so we

can improve emission levels and

engine performance.

QUALITY SOLENOIDS BOOST PRODUCTION ECONOMY

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 manufactur-

ers 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 solenoid-

based valves.

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.

We are well aware of the specific requirements for end product function-

ality, even in demanding environments.

RIGHT STATORS LESSEN THE ENVIRONMENTAL IMPACT OF DIESEL ENGINES

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 electro-

magnetism means we can develop and manufacture

stators that meet market requirements across the board.

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.

Our combined knowledge of mechanics and electromagnetism

means we can develop and manu-facture stators that meet market

requirements across the board.

THE LAMINOVA HEAT EXCHANGER

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 super-

charged petrol and diesel engines.

Laminova oil coolers are more efficient than the competi-

tion 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-manu-

facturers world wide.

The small and flexible package is used for both cooling

and heating applications in many different motor vehicles.

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 oil coolers are more efficient than the com-

petition due to the unique patented core design.

THE SENSORS PRODUCT AREA has measurement

sensors based on both hall sensor and inductive technology.

Inductive sensors are easily adapted to various applica-

tions. They are fully contact-free and are highly accurate.

Potential application areas include clutch and brake wear

indicators, gear position indicators and measurement of

liquid levels and pressure.

SEM has been working with sensors for close to 30 years. We manufacture inductive and contact-

free sensors that are designed to work even in demanding environments.

The history of Svenska Elektromagneter

Since it was founded in 1915, Svenska Elektromagneter –

SEM – has played an active role in swedish industry.

The SEM factory in Åmål delivered the very first igni-

tion equipment to Thulinverken in Landskrona during

World War I. The equipment was installed in the plane

Tummelisa, which had its inaugural flight immediately

following the war. Reliability and quality were decisive

factors behind the purchase and Svenska Elektromag-

neter was at that time the only company able to meet

the demanding criteria.

SEM has retained its focus on electromagnetism and over

long periods the company’s knowledge and products

have been unique not only in Sweden but worldwide.

Precision and environmental concern

SEM’s original idea remains firm: We shall develop and

manufacture products that, in an energy-effective man-

ner, initiate, generate and transform power.

Performance and technical precision have gradually been

extended with environmental requirements. Within the

company there is an intensive, ongoing process to de-

velop technology that can make a positive contribution

to the environment.

SEM is certified in accordance with ISO/TS 16949

and ISO 14001. Our work environment is certified

in accordance with OHSAS 18001.

COOPERATION, PROFESSIONALISM AND MUTUAL RESPECT

Production in Sweden and China

SEM has modern industrial production facilities in

Åmål, Sweden and Suzhou, China. Our head office is

in Åmål, which is also home to our product develop-

ment, order management and quality control.

Every day we aim to improve the way we work so we

can give our customers the best possible service and

value – technically as well as commercially.

Professionalism and mutual respect are two of the cor-

nerstones in our daily work, the third is close coopera-

tion with our customers. These days as the path from

idea to final product gets shorter and shorter, it’s more

important than ever to collaborate and share our skills.
