    HARTFORD, Conn.--July 16, 2002--Sisu Diesel of Finland has selected Stanadyne Corporation's Fuel Manager(R) diesel fuel filter and water separation units for both the pre- and final diesel fuel filtration systems on its Tier II engines, according to Simon Garner, director of sales and marketing for Stanadyne's Power Products Division.
    Sisu Diesel supplies engines primarily for the agricultural sector to customers such as Valtra, Case, Steyr and Massey Ferguson tractors and MF combine harvesters, as well as to portions of the forestry sector and other off-road applications.
    Stanadyne has had a long partnership with Sisu Diesel, which now is extending the Fuel Manager to its final filtration application needs after having used the system several years for pre-filtration. All future Sisu diesel engines will be fitted with both pre- and final filter Fuel Manager units. Stanadyne also supplies Sisu Diesel with injectors, injection sensors, diagnostic equipment and injection pumps for Tier I applications.
    The final filtration unit for the Sisu Tier II diesel engines consists of an assembly with the longest 5 micron final filter--6-inch type--with no optional features other than constant air bleed (CAB), which is integrated into the filter header. The CAB permanently purges air back to the fuel tank, allowing a quick and automatic purge of the low-pressure fuel circuit when servicing the filter elements on both pre- and final filter units.
    The Stanadyne Fuel Manager is a completely integrated diesel fuel filtration system that incorporates all the required features in one easily installed and maintained unit. With its exceptional flexibility and modularity, the Fuel Manager system easily accommodates the full range of pre-filter assemblies needed to meet every specific Sisu diesel engine category and fuel injection system configuration, as was as final customer application requirements.
    The various pre-filter assembly configurations always include one of the longest 30-micron water separator pre-filter elements of the range--5.1-inch type--to meet servicing interval requirements, as well as additional modules or options to meet specific application and the final customer requirements.
    These include: a transparent bowl or a "water-in-fuel" electronic control feature to monitor water separated from the fuel by the filter element's high performance water separation; an integrated electric lift pump with auto-regulation of the outlet pressure to supply the injection pump with a controlled inlet fuel pressure; 4-port filter headers that allow Sisu Diesel to simply install the same filter and pre-filter units in different ways to meet various engine layout configurations and room availability.
    Sisu Diesel's selection of the Stanadyne Fuel Manager for pre- and final filtration helps the company to meet the new Tier II engine performance and emissions requirements with a solidly reliable, standardized fuel filtration system that also reduces service parts inventories. Other benefits of the Fuel Manager include: quick and clean changes of the filter element; easy, tools-free servicing; performance integrity; and better warranty control thanks to a key track arrangement specific for Sisu Diesel.
    Sisu Diesel, which is located at Nokia in Finland, manufactures 3-, 4- and 6-cylinder diesel engines from 60hp up to 400hp. The company produced 24,000 engines in 2001--a 16% increase over the previous year--and had a turnover in excess of 113 million Euros. Sisu Diesel Inc. is a subsidiary company within the Finnish Partek Corporation, which in total employs over 12,000 people with a turnover in excess of 2.7 billion Euros in 2001.
    Stanadyne Corporation is a leading manufacturer of diesel fuel injection and filtration systems for the automotive, construction, industrial and agricultural vehicle and equipment markets, and supplies gasoline engine components to major automakers. The company, which has a worldwide network of some 1,200 sales and service agencies, is the only leading manufacturer of diesel fuel pumps and injectors to market its own diesel fuel conditioners.
