DEVICE FOR TREATMENT OF FUEL Russian patent published in 2000 - IPC

FIELD: manufacture of engines; treatment of fuel in fuel supply systems of carburation internal combustion engines. SUBSTANCE: device has hollow housing with electrode located coaxially inside it, plug made from dielectric material and fitted between electrode and housing, discharge passage provided at opposite end of housing and inlet passage made in side wall of housing. Housing is made from conducting material; it performs function of second electrode; groove found on electrode has form of spiral located along longitudinal axis over at least part of electrode. At least part of inner surface of electrode is cylindrical in shape; inner diameter D of housing and outer diameter d of electrode satisfies the following relationships: 2 < D/d < 3 and 10 < L/d < 20, where L is length of electrode; t is pitch of spiral; s is depth of groove; m is width of groove; they satisfy the following conditions: 0,28 ≤ t/d ≤ 0,64; 0,06 ≤ s/d ≤ 0,2; 0,06 ≤ m/d ≤ 0,2 M is length of groove along longitudinal axis of electrode which satisfies the following condition: 0,2 ≤ M/L ≤ 1. Groove may have rectangular, or trapezoidal, or triangular or concave profile. EFFECT: improved quality of treatment of fuel. 8 cl, 6 dwg, 1 tbl
