High speed engines Atlas Crudeoil Engines The types T and BW are both trunk-piston engines; in larger sizes they are designed with cross-head and guides. The T and BW engines are especially suitable for power stations or industrial plants, either direct coupled to electric generators, or with belt or rope drive. vessels e. g. compressors, winches, electric light dynamos, etc. This high speed type is also in a modified form used for Diesel electric railway cars, and at present built up to 300 BHP at 550 r. p. m. and 12 cylinders. The Atlas Crude oil engines are built on the 2-cycle Stationary principle in sizes from 5 to 60 BHP at speeds of 550 Type -250 r. p. m. in the single-cylinder type, and up to 120 BHP in the two-cylinder one. They are also supplied in a portable type. These engines are particularly suitable for smaller workshops and for agricultural purposes, as well as for all places where power requirements are moderate and low running costs desirable. These engines are also built in self-contained sets direct connected to plunger pumps, centrifugal pumps, electric generators and air compressors. Polar Diesel Engines 8 BHP Atlas crude-oil engine direct coupled to dynamo The Polar Diesel marine engines are designed either on the 2-cycle or 4Marine Type cycle principle, in sizes from 100-3,000 BHP, types P, MP, A and S. They are all of them direct reversible. 2-cycle Type Polar Diesel 2-cycle marine engines in sizes from 110-500 BHP with trunk-piston type and four power cylinders; speed 280-150 r. p. m., type P. Fuel consumption about 0.447 lbs. per brake horsepower hour. The characteristic feature for this type is its being provided with two manoeuvring cylinders placed in front of the four power cylinders. The former comprise the so-called manoeuvring or control engine used for the reversing, and driven by compressed air from special tanks in which it has been compressed by the main engine while propelling the ship. While the engine is running, the control engine supplies the air necessary for expelling the exhaust gases from the power cylinders. This engine type is used to advantage in both cargo and passenger vessels. Polar Diesel, 2-cycle marine engines in sizes from 700-3,000 BHP of the cross-head 2-cycle Type type, with from four to six power cylinders, type MP. Speed 120-75 r. p. m. Fuel consumption about 0.436 lbs. per brake horsepower hour. In these engines the power cylinders are closed at the bottom, and the lower side of the pistons serves to compress the air necessary for cleaning the cylinders of exhaust gases, and for supplying the air used during reversing. By this means special cylinders for supplying air for reversing are rendered unnecessary. Used for both cargo and passenger vessels. Polar Diesel low speed marine engines, cross-head 4-cycle type, built in sizes from 4-cycle Type low speed 700 3,000 BHP, with from six to eight power cylinders, type A. Speed 120-75 r. p. m. Fuel consumption about 0.413 lbs. per brake horsepower hour. The reversing arrangements are similar to those of the MP type. Polar Diesel high speed marine engines, of trunk-piston and 4-cycle type, built in 4-cycle Type high speed sizes from 350-1,000 HP. Have six cylinders and a speed of 450-325 r. p. m., type S. The Atlas Crude oil marine engines of the 2-cycle type, built in sizes from 40 to 80 BHP having a speed of 300 r. p. m., one and two cylinders. Fuel consumption 0.548 lbs. per brake horsepower hour. These en gines are especially in favour for fishing boats, smaller cargo craft for the coast trade, and as auxiliary engines for sailing vessels. Constructed either with reverse gear or arrangement for propeller with reversible blades. The Atlas crude-oil engines work without injection of water into the cylinder or combustion chamber. 1200 BHP Polar Diesel direct reversible marine engine, Type A 6 Z; speed 120 r. p. m.

The Svedala Works in 1923 Machines and appliances Consulting work Historical Situation and shipping facilities Part of the Works in 1908 To the leadership and energy of the founder of the firm, Åbjörn Anderson, is due the rapid expansion of the establishment, from a small workshop in 1882 to the important position it occupies at the present time, the company being rated as the leading manufacturers in their special line. The first speciality consisted of agricultural machines, and, when circumstances made it advisable to alter the production programme, the manufacturing was adapted for the construction of machinery used in the brick and tile trades, ore and rock crushing, including road construction and allied branches. In 1916 the business was converted into a limited company. The output of the works has increased steadily and rapidly, reaching the figure of 6,500,000 Kronor in 1918. The Works are favourably situated in South Sweden on the railway lines to Malmö and Trelleborg, the principal ports of South Sweden, open all the year round. Goods are loaded direct on railway cars at the factory and thence transported to the ports of shipment. |
