Experimental investigations of the diesel engine operation on artificial gas mixtures, their composition other than the air composition
// Dvigatelestroyeniye. — 1989. — ¹ 12. — P. 3–4.
Key words:
engines.
Experimental investigations showed characteristics of the parameters variation of the diesel engine 6Ch12/14, operating on artificial gas mixtures other than air mixtures. Artificial gas mixtures are supposed to divide into "light" and "heavy" in dependence on the effect on the self-ignition time delay. It is shown that "light" mixtures are preferred to use as an actuated body. In such a case its effectiveness can be improved by the internal combustion engine governing.
