摘要： This invention relates to a compressed air starter including pneumatically operating starting valves for diesel engines, wherein one main starting valve is connected to the cylinder head of the engine and is provided with a valve body, which co-operates with a valve seat in order to alternately open and close an inlet opening for compressed air to one cylinder, whereby during the start up of the engine, starting air (compressed air) continuously is supplied to the main starting valve, said valve body including one servo piston, which is controlled by servo air from a supply of servo air, which servo air acts on the servo piston during moments related to the working phase of the engine.The invention simplifies the pipe arrangement for the compressed air in a diesel engine with several cylinders where there is usually arranged a main distributor for distributing the servo or pilot air, which controls the starting valves. The invention utilizes a magnetic valve (17), which is connected to the main starting valve (8,9,10) and has a valve slide, which in one position (I-II) connects the supply (16) of servo air with a compression face of the servo valve (10), said servo valve thereby being activated to drive the valve body (8,9) to the opening position and, in a second position (II-III) controls the outlet from the supply (16) of servo air so that the servo piston drives the valve body (8,9) to a closing position, said magnetic valve (17) being controlled by electric signals from a transmitter (20) controlled by the crank shaft or by a second shaft (22) rotating in accordance with the working phase of the engine.

摘要： The invention relates to a method and apparatus for controlling the braking action of a diesel engine having several cylinders. Hereby valves of the cylinders are opened and closed for supplying compressed air and/or venting the cylinder during a certain moment of the compression stroke. This is accomplished by a transmitter which produces an electric pulse that is transformed into an electro-magnetic force, which controls a valve of a pressurized pilot air system for opening the valve of the particular cylinder.

摘要： This invention relates to a method and a device for controlling the cooling of internal combustion engines in order to reduce the corrosive wear of cylinder barrels and piston rings. The corrosion substantially is caused by the sulphur content of the fuel. In a Diesel engine the combustion of the fuel always takes place at a relatively great air excess, which implies that the formation of sulphur trioxide exceeds the formation of sulphur dioxide. Together with the water vapor in the flue gases, in addition to sulphurous acid the stronger sulphuric acid is formed. The corrosion in combination with the wear result in a much too short life of the cylinder liners and piston rings and constitute a significant economic problem. Known tests show for the corrosion of steel in flue gas with 0,01 and 0,02% SO.sub.3 -content a very distinctive maximum at about 150.degree. C., but corrosion minima on both sides of said maximum. The corrosion can be reduced by maintaining the surface temperature for cylinder barrels and piston rings below the lower temperature limit for maximum corrosion due to SO.sub.3 -content in the flue gas by tempering the coolant while the engine is subjected to a load up to a certain partial load, and at increasing output and upon arrival at said partial load causing an abrupt increase in the surface temperature to a value above the upper temperature limit for said maximum corrosion, and maintaining the surface temperature thereafter above this value by tempering of the coolant.
