    ELABORAREA ŞI OBŢINEREA LUBRIFIANŢILOR SPECIALI ŞI TESTAREA PROPRIETĂŢILOR DE EXPLOATARE A ACESTORA
    (CEP USM, 2010) Crăciun, Аlexandru; Crăciun, Svetlana; Мoraru, Victor; Sajin, Tudor; Albert, Boris
    The work is dedicated to development of composition and technology of plastic lubricant (PL) for joints with equalangular velocities production and determination of its tribologycal properties. It has been established that the proposed PL possesses tribologic advantages over the ubiquitously applied PL Automotive (Company LOBRD) very well known in the world and practically is not exceeded by PL ШРУС-4 applied for the same tasks, currently produced in Ukraine and Russia.The work contains data on the technology of obtaining and determination of the specific electrical resistance of an electroconductive lubricant. It has been established that both, according to the electro conductivity and exploitation properties, this lubricant exceeds analogues and prototypes.

    TEHNOLOGII MODERNE DE REDUCEREA EMISIILOR DE OXIZI DE AZOT ŞI SULF DIN GAZELE DE ARDERE
    (CEP USM, 2008) Craciun, Alexandru; Duca, Gheorghe; Sajin, Tudor
    Modern technologies for diminishing of the content of NOx and SOxin combusted gases based on the application of selective, low temperature, njnctalytic reducer, as well as w ith application of electric corona discharges combined with alternative electric field that influence the stream of burned gases, along with injection of ammonia are presented in the paper. A new catalyst combined with a nitrogen trap is presented in the work as well.
