Advantages in the supercharging of the diesel engines D-21 and D-21A, using the combined mixture forming
// Dvigatelestroyeniye. — 1987. — ¹ 6. — P. 3–5.
Key words: engines.

An effect is considered of the primary fuel (gasoline, gas condensate, methanol) and other factors of the combined mixture forming on the compression and cycle operation. The method to form the mixture is shown to be used for the diesel engine supercharging on its mean effective pressure. The supercharging degree depends on the primary fuel air excess coefficient and thermal stress of the diesel engine.
