一辆奥迪100(五缸、K 型燃油喷射)轿车,因怠速不稳,又连烧两个燃油泵而送修。主修人认为是燃油压力过高导致喷油过多而怠速不稳,燃油泵由于过载而烧毁。于是他决定调整调压器降压。书上介绍调压器在燃油分配器上(而该车的调压器在分配器与大梁的夹缝中),于是拆开燃油分配器。但未见调压器,就调节了5个压差阀和控制柱塞的高度。未收到预期效果。反复调整拆装20余次,越调越乱。最后出现打马达不易发动,松开马达就熄火,快速连踩油门,
An Audi 100 (five-cylinder, K-type fuel injection) sedan, because of idle instability, and even burn two fuel pump and repair. The main idea is that the fuel pressure is too high and lead to excessive fuel injection idle instability, the fuel pump burned due to overload. So he decided to adjust the regulator buck. The book describes the regulator on the fuel distributor (and the car’s regulator in the distributor and the beam in the gap), then open the fuel distributor. But no pressure regulator, adjust the 5 pressure valve and control the height of the plunger. Did not receive the expected results. Disassembly repeatedly adjusted more than 20 times, the more tune more chaos. The last appeared hit the motor is not easy to start, release the motor to turn off, quickly step on the accelerator,
