Roodium Roodium (kr rhodeios ,,roosa, roosavärviline") on keemiliste elementide perioodilisussüsteemi VIII rühma element, järjenumbriga 45. Roodiumi sümbol on Rh (rhodium). Roodiumi aatommass on 102,9055, aatomiraadius on 135 pikomeetrit Looduslikku roodiumi moodustab stabiilne isotoop 103 45 Rh (massiarvuga 103). Roodium on väärismetall ning plaattinametall (plaattinametallideks nimetatakse ka teisi omadustel plaattinale sarnanevaid elemente: iriidiumi, osmiumi, palladiumi ja ruteeniumi). Perioodilisussüsteemis loetakse teda koos koobalti, iriidiumi ja meitneeriumiga koobaltigruppi (9. gruppi).
The CFI unit contains an design, and delivers fuel under pressure to the (CO) to an acceptable level. ACT (Air Charge Temperature) sensor and a engine. Electric power to the pump is supplied The catalyst consists of a ceramic throttle valve (see illustration). The ACT via a relay which is controlled directly by the honeycomb coated with platinum and sensor passes information to the EEC IV EEC IV module. The pump contains a non- rhodium, housed in a metal exhaust box. The module, which uses the information to return valve which maintains pressure in the honeycomb design presents a large surface determine the engine's fuel requirement. The system after the ignition is switched off, to area to the exhaust gas promoting maximum inlet air then passes the throttle valve into the assist starting. conversion.
