Gases produced by a combustion engine (1), e.g. crankcase gases, are conducted through a separation chamber formed and surrounded by a centrifugal rotor (R), by means of which the gases are caused to rotate, so that particles suspended in the gases are separated by means of centrifugal force. The centrifugal rotor (R) is caused to rotate by means of a pressure fluid that is generated by means of t...

The invention concerns a lead-acid battery having all the surfaces of all the electrodes under high pressure and their circumferences kept unchanged by support from mechanically rigid cell walls such that only the thickness of the electrodes is allowed to expand under strong resilient load during the discharge and return during charge. The pressure is 0,49 -10<5> - 9,81 -10<5> Pa (0.5-10 kp/cm<2>)...

An engine control method for reducing emissions during cold start and idling is provided, which includes: opening an ISA with a predetermined opening rate such that an air/fuel ratio becomes higher than a theoretical air/fuel ratio, and minimizing an engine load caused by an automatic transmission; performing air/fuel ratio control and ignition timing control based on engine speed and engine load,...

An electrode plate for an alkaline storage battery of the present Invention includes a conductive core material as a current collector, in which a plurality of through-holes are linearly provided in the core material so as to be parallel to a longitudinal direction of the core material, each through-hole having an aperture area of 10 mm<2> or less and at least two pairs of opposite sides parallel ...

The container has a top (E) with an inner duct (1) linked to the container at one end and to an outlet (10) at the other. The duct is at least partially closed by an insert (2) with a selective porosity which permits a controlled flow of the product outwards on the one hand and a filtration of indrawn air on the other, holding back contaminants and/or biological pollutants. The top is covered by a...

The present invention relates to fuel compositions containing hydrocarbon fuels in the gasoline boiling range and organic nitrogen-containing compounds selected from organic nitrates and/or organic nitro compounds. The fuel compositions exhibit improved ignition properties, including reduced emissions and reduced misfires.

Foam blowing agent blends of D11 and a pentane are provided, as are polyol premixes containing such blends. The resulting foams exhibit dramatic improvement in fire resistance.

In order to improve machinability of a sintered compact, a phosphate compound of an alkali earth metal (calcium phosphate compound or the like) is mixed with an iron-based powder, or an alkali earth metal fluoride (calcium fluoride, or the like) is further mixed with the iron-based powder. Alternatively, the alkali earth metal fluoride, together with a graphite powder, is preferably fixed to reces...
