  • Publication number: 20200124015
    Abstract: The present invention relates to a spark plug extension body connecting an ignition coil with a spark plug for a spark ignited internal combustion engine, as well as a method for providing such a spark plug extension body for reduction of partial electrical discharges in the spark plug extension body. In conventional spark plug extensions are coil springs used as electrical conductor against the spark plug terminal and/or ignition coil terminal. These coil springs cause Corona effects and short circuiting requiring replacement of the spark plug extension. With the invention the entire electrical conductor (CRu, 64, CRL) is in a rod like form and at least both ends (CRu, CRL) of the electrical conductor (CRu, 64, CRL) are made as a monolith in a flexible and electrically conducting polymeric material, preferably electrically conducting rubber.

  • Publication number: 20130140243
    Abstract: A method of purifying raw water comprises the steps of supplying the raw water to a generally vertical, open-ended inlet cylinder (23) in a reservoir (20), exposing the water in the inlet cylinder (23) to air for accomplishing oxidizing of matter, such as iron, manganese, and hydrogen sulphide in the water and/or agitation of the water, allowing the oxidized matter to fall down by gravity to the bottom of the reservoir (20), allowing the purified water to flow upwards past the inlet cylinder (23) and through a distribution disc (24) in the reservoir (20), and removing the purified water from the upper part of the reservoir (20).

  • Patent number: 8133394
    Abstract: Wastewater can be purified in a device, which includes a cup-shaped vessel, having a wastewater inlet tube for the water at a certain level and an outlet tube at a lower level than the inlet tube, and a horizontal distribution disc, which vertically divides the vessel, has at least one opening and is provided with a substantially vertical distribution tube for receiving the water from the inlet tube. Water above the distribution disc is pumped through a filter head with a filter. Filtered water is let out through the outlet tube, whereas unfiltered water is transferred back to the distribution tube. Flocculation agent is added to the unfiltered water before reaching the distribution tube.

  • Patent number: 7509941
    Abstract: An apparatus and method for use with a carbureted internal combustion engine that accurately controls the amount of fuel that passes through the carburetor into the combustion chamber of the engine. A controlled triggering system controls the activation and deactivation of a solenoid. The solenoid, in turn, operates a plunger that varies the flow of fuel during the fuel intake cycle of the engine depending on the amount of fuel needed by the engine under any operating load. Thus, an engine can run leaner under partial load and run richer during periods of load and acceleration. By controlling the air-to-fuel ratio lower engine emissions and fuel consumption can be achieved.

  • Publication number: 20080011272
    Abstract: An apparatus and method for use with an internal combusting engine that accurately control ignition timing. Reference signals are created which are used to determine both the mean engine speed as well as irregular speed. Control logic uses this engine information to accurately predict the future rotational position of the engine. The ignition timing is then adjusted to release the spark at the appropriate time.
