PCT No. PCT/SE95/00498 Sec. 371 Date Nov. 1, 1996 Sec. 102(e) Date Nov. 1, 1996 PCT Filed May 5, 1995 PCT Pub. No. WO95/30828 PCT Pub. Date Nov. 16, 1995A method and a device of controlling the amount of fuel delivered to a combustion engine (1), e.g. of two-stroke or four-stroke type, wherein the fuel is supplied through an intake passage (2) intended to deliver air (3) and fuel (4) to the cylinder (5), said intake passage being opened and closed by a piston (6) or by a special valve (7). The fuel supply to the intake passage (2) is effected upstream from the piston (6) or the valve (7) and in response to the opening and closing of the intake passage (2) varying flow speeds and pressures are produced in the passage and the fuel supply system (8) is of a kind the supply amount of which is substantially affected by this variation, such as a carburetor (9) or a low-pressure injection system (10). In order to regulate the fuel supply to the engine fuel a brief cut-off takes place in the fuel-supply system (8) of the entire fuel flow or the part flow and the brief cut-off is arranged to take place to an essential extent during a part of the engine revolution when the intake passage is closed and the fuel supply accordingly is reduced or has ceased. |
