Delivery-valve problems are cylinder specific. If the valve sticks open, no fuel passes to the associated injector. Leakage is harder to diagnose. White smoke that…
Injectors feed through delivery valves mounted on the distributor head or above each barrel on inline pumps. These check valves open under pressure to supply…
Other than periodically checking the oil level for in-line pump reservoirs and adding rust inhibitor to the fuel before long-term storage, injector pumps require no…
Injection pumps have two provisions for synchronizing fuel delivery with piston movement. Timing marks on the drive gears establish the basic relationship. Elongated mounting-bolt holes,…
Nearly 50 million VE pumps have been produced since introduction in 1975 with applications ranging from fishing boats to luxury automobiles. Figure 5-9 sketches a…
Figure 5-7 illustrates a CAV system for medium trucks. The engine-driven feed pump moves fuel from the tank to the filter and regulating valve. Fuel…
The parts breakdown for a Bosch size A Series PE inline pump for six-cylinder engines is shown in Fig. 5-3. Shims (21 and 49) establish…
The big breakthrough came with the development of the Bosch inline pump, used today in a form almost identical to the first production run of…
The need for more compact and silent submarine engines led the British arms maker Vickers to develop airless, or solid, injection. One can make the…
