Scania uses soft magnetic composites to reduce vehicle emissions

In order to adapt to the new EU and US truck exhaust emission standards, Scania, a Swedish truck manufacturer, is not using catalytic devices to purify exhaust gas like other truck manufacturers. Scania’s approach is to develop new types of More energy efficient and environmentally friendly engine. This requires a new design of the truck engine, especially the fuel injection process of the engine. To this end, Scania has teamed up with Cummins, the world-renowned North American truck engine manufacturer. The newly designed engine has faster fuel injection, higher injection frequency and greater injection pressure. The newly designed engine uses a new type of stator that is used to open the inlet valve of the engine. SEM Sweden has a contract to manufacture the new stator. SEM uses the soft developed by Höganäs. Magnetic composite materials are used to make such a stator.

SEM and Burgess-Norton of the United States have cooperated in the field of pressed magnetic powder. Burgess-Norton has long experience in suppressing magnetic powder and has invested in equipment and personnel training to suppress soft magnetic composite powder. Ted Baker, director of the soft magnetic division at Burgess-Norton, said: "Thanks to the cooperation with Höganäs, we can now suppress more stator parts than before, and the quality is very stable. The magnetic properties of the stator are obtained. Improved, it can respond to electric pulse signals faster and more powerfully, and improve the performance of the inlet valve.” Both Scania and Cummins are satisfied with the newly developed stator, which has doubled in just one year.

Transfer Pipet

Practical disposable transfer pipettes, made from natural low density polyethylene (LDPE). The transfer pipet is simple and safe to use with a long shelf life; no issues with broken glass, cracked or loose bulbs. Additional advantage is that with the single piece design lager amount can be transferred by allowing fluids in the bulb. These plastic transfer pipettes are ideal for transferring small amounts of fluids for microscopy sample preparations or to prepare mixtures or staining solutions. The extra fine tip enables transferring minute amount of fluids. These cost-efficient plastic transfer pipettes are disposable and intended for one-time use. Ideal for educational and research environments. Can be used for fluids up to 70°C, please take care to protect the fingers squeezing the bulb. Available in six sizes/styles: 0.5ml, 1ml, 2ml, 3ml, 5ml, 10ml.
