Title: Fuel injector mechanism for internal combustion engines
IPC: F02M69/46
Filed: 1957-08-30
Abstract: 866,712. Regulating. BORG-WARNER CORPORATION. Aug. 30, 1957 [Sept. 6, 1956], No. 27434/57. Class 7(6). The control member 68, of a fuel injection pump is adjusted in accordance with engine load by a suction-actuated device 126 responsive to intake manifold pressure and with mass air flow by a suction responsive device 121 connected to orifices 143, 144, on opposite sides of the throttle valve 137, the pump output being decreased above a predetermined throttle opening by a correcting orifice 142 controlled by a throttle operated needle 148. The rod 68 is controlled by a cam 100 carrying pins 101, 102, engaging in guide grooves 108, 106, in guide plates 107, 103, the cam 100 being moved axially in accordance with engine load by a diaphragm 128 subject to intake manifold suction transmitted through pipe 153 and moved laterally through the guide plate 103 by a diaphragm 123 controlled by a suction varying with mass air flow in a pipe 147 which is connected to the pressure tappings 143, 144. At part throttle openings the pressure in pipe 147 is intermediate that at the points 143, 144, and varies inversely with mass air flow. On an increase of load, the diaphragm 128 raises cam 100 so that the pin 68, which is held against the cam face by a spring-loaded lever 116, is moved to the right to increase the fuel supply. Similarly on a decrease in mass air flow the suction in pipe 147 decreases and diaphragm 123 moves plate 103, and thereby cam 100, to the right to increase the fuel supply. On rapid opening of the throttle valve 137, plate 103 is moved quickly to the right and an extension arm 109 thereof contacts plate 107 to force it to the right, producing an enriched accelerating mixture. During over-running, the high suction in pipe 153 pulls lever 111 downwards so that a projection 119 thereon contacts lever 116 and forces it to overcome the force of spring 125 and move member 68 and cam 100 to the left to cut off the fuel supply. The suction produced in pipe 147 by orifices 143, 144, is decreased above a predetermined throttle opening by opening of an orifice 142 by a needle 148 controlled by a cam 149 on the throttle spindle 138 and a second auxiliary orifice 146 is opened at idling to reduce the suction and produce an enriched idling supply. A third auxiliary orifice 145 is controlled by a capsule 151 responsive to engine temperature and increases the fuel supply during cold running and a fourth auxiliary orifice 154 controlling a bleed 155 connected to pipe 147 is controlled by a capsule 157 in accordance with atmospheric pressure and temperature. An idling air by-pass 160 is adjusted by a needle 161. The pump is identical with that described in Specification 866,713.
