Title: Fuel weighing device
Inventor: MURAJI TETSURO
IPC: F02M69/52
Filed: 1989-03-13
Abstract: PURPOSE:To provide high weighing accuracy, excellent response and low-priced manufacture by adjusting the fuel pressure difference across an opening according to the pressure of a manifold pipe through a mechanical adjusting means, and changing the area of the opening according to engine speed through an electric adjusting means. CONSTITUTION:When manifold pressure Pm increases with sucked air flow, the first diaphragm 4 displaces upwards, and a valve 9a is relocated on an opening direction. Then the fuel flow flowing in an upstream chamber 2 from a flowing-in port 2a increases to increase fuel pressure P1 of the upstream chamber 2, and passes through an opening 11a for weighing, increasing the fuel flow flowing in a downstream chamber 7. As a result, the pressure difference (P1 - P2) of the opening 11a changes in proportion to the manifold pressure Pm. Moreover, the sectional area A of the opening 11a changes with engine speed, so fuel flow increases according to the manifold pressure and the engine speed. It is thus possible to meter a weight so as to increase the fuel flow required according to the increase in intake air amount.
