ON THE WAY TO THE RECORDSIn 1988 there was a serious prerequisite to the beginning of work on items for ignition, and primarily on spirals candles glow plugs of internal combustion engines. This was due to the currency problems, which almost completely stopped the flow of imported candles and candle-heads. Also affected by the desire to have a set of coils with different geometrical parameters (for fine-tuning of the engine).

It should be noted that the alloys with high content of iridium is used in the production of domestic candles and heads, were not suitable for modern high-speed engines. Practice has shown that the use of heads “Rossi” in comparison with GSK allows us to significantly raise the power, and significantly increased resource the spiral. Therefore, the first step was the creation of spirals, as the Italian for these two key indicators. The problem was solved rather simple way: the remains of burned-out, carefully preserved for several seasons, melted and stretched into a new wire. A further direction of searches was the production of the alloy with improved catalytic properties (encouraging results have already been obtained). But most importantly — it turned out that in our country produced alloys, the application of which heads GSK would significantly increase their competitiveness on the international level.
In parallel with the work on spirals was improving the design of the cylinder head in General. At the time, the transition to head of the “coke” has significantly increased the maximum power of the motors. For a long time they were considered ideal, so the operational difficulties of attention was practically not addressed. But back in 1986 we came to the conclusion that the Assembly and disassembly associated with the replacement of the burned out spiral, adversely affects the stability of the cylinder pair. Apparently, this is caused by changing mechanical stresses in non-uniform tightening of threaded elements. For smoothly running engine is not desirable.
Glow candle type
Glow candle type “piston”:
1 — housing (aluminium alloy AK4), 2 -pressure washer (brass LS 59), 3 — a Central electrode (article 10, article 45, A12), 4 uplotnitelya washer (parent),5— helix (alloy of platinum, ruthenium and regenica).

The idea arose piston-candles. In the Assembly of the head cooling is fixed without candles. Next, constantly turning the crankshaft by hand, to achieve minimal friction of the piston at TDC by alternate tightening of nuts of fastening of a head.
It should be noted that there are already several designs of this node. Although a “cap” and seems complicated, there are certain reasons for that decision. In the process of exploitation of imported heads revealed a serious drawback: the possibility of burnout of the strips, sealing the Central electrode. The result was a fit model with a rotating screw and… zero valid “points.” While small leaks that are difficult to spot on the ground, significantly decreased capacity. Threaded the same packing method applied, has almost one hundred percent reliability.
For the manufacture of gaskets used paronite grey thickness 0.9 mm. during the compression the thickness is reduced to 0.5 mm. Spiral made of wire diameter 0.16 mm (to 0.2 mm), outstretched through a carbide die. Wrapped on the mandrel. The Central spiral electrode is attached by spot welding, and the housing — zachekanka in a pre-made groove. Spot welding uses a simple homemade device.
