Sisu Diesel is making major investments in the development and production of more fuel efficient and reliable diesel engines that comply with Tier 3 emissions standards. The three-year investment programme will double production capacity at both the Nokia plant in Finland and the Mogi Das Cruzes plant in Brazil.
The engine assembly process has been entirely reorganised with a focus on increasing the level of automation and developing the internal automation system of processes. The engines are assembled to an increasing extent by several robots along fully automated and flexible production lines. Updated instructions for the manual fitting stages are following the engine in RF tag and displayed on the screen for the mechanics. The warehouse systems have also been automated, and the internal logistics for completed engines are handled by the state-of-the-art automated guided vehicles.
The production of engine parts has also been improved by modernising the manufacturing processes of selected key components and increasing capacity to meet the needs of growing engine production. The production efficiency of cylinder blocks has been increased, as has the flexibility of manufacturing different engine types. All 2- and 4-valve cylinder heads are manufactured completely on a new flexible and automated production line. The production capacity of gear wheels, rocker arm assemblies and housings has been increased to meet future demand.
The capacity of engine research and development is also being increased. The engine development laboratory will feature eight new engine test benches, as well as state-of-the-art management and data collection systems. The testing capacity will be doubled, and the technical sophistication of the test benches, cooling capacity and ventilation will improve considerably. It will also be possible to test bigger engines.
=======================
New engine laboratory for Sisu Diesel
Major investments are being made into engine research and development at Sisu Diesel’s Linnavuori factory. R&D capacity has already been increased by around 10 percent by increasing the number of technical personnel. Construction of a new engine development laboratory has also begun, and work will be completed in February 2007. The value of this investment is approximately EUR 2 million. The new laboratory will be opened in autumn 2007 following the installation of machinery and equipment.
The new engine laboratory will feature eight new engine test benches, doubling the current capacity. The technical sophistication of the test benches, cooling capacity and ventilation will improve considerably, making it possible to test also bigger engines. The new laboratory’s automated data collection system is based on the Stars test environment.
The new 400-square-metre building is located next to the existing engine laboratory. The ground floor will house technical facilities, the second floor will house the actual engine test benches, and the third floor will house the test control room and an office for more than 10 R&D technicians.
The new laboratory ensures Sisu Diesel’s important, competitive and expanding R&D operations also in the future. The owner’s commitment to making long-term investments in the engine business is important for both the factory and its clients.
=================
Biodiesel can be used with SisuDiesel engines
SisuDiesel common rail engines are approved for use with up to 20 percent biodiesel (B20). Engines that do not feature common rail injection can be fuelled with 100 percent biodiesel (B100).
Sisu Diesel is continuing tests with biodiesel fuels. If the results of these tests are favourable, it is possible that greater concentrations of biodiesel could be used in the future.
The biodiesel fuel must comply with EN 14214 or ASTM D 6751 norms. The biodiesel used in Europe is typically rape methyl ester (RME), whereas in North America soy methyl ester (SOME) is generally used. Other plant oils can also be used to produce biodiesel. The biodiesel fuel must be esterified. Non-esterified, cold-pressed or other biodiesel fuel that does not conform to the above norms may not be used.
SisuDiesel’s engines do not need to be modified before using biodiesel. Whenever a blend of more than 5 percent biodiesel is used, however, the engine oil, oil filter and fuel filter must be changed twice as often as required by the normal service interval. In addition, Sisu Diesel recommends that a separate pre-filter be fitted between the fuel tank and engine if biodiesel is used regularly. The water filter should be checked frequently and carefully, as biodiesel is more liable to absorb condensed water than normal diesel fuel.
Engine performance with biodiesel is the same as with normal diesel. Biodiesel also does not damage the environment in the same way as regular diesel, for example if it leaks into the ground.
