Hi Sutripta,

Actually how many Technical Manuals Bulletins on FIPs & Fuel Injections left

For the VKD-04200 14 sides left.

Arka

Hi,
Unable to read the text inside the graphs/ diagrams, either on screen, or printed.

Going through the text, interesting and informative, but no 'Aha' moments.

Used to have the manuals for some of the Woodward governors (PGA and PSG), but I'm sure will also be available on the net somewhere.

Do you have the details of the Bosch VE?

Regards
Sutripta

Hi Sutripta,

If you click on the pics/scans they will enlarge.

Regards,

Arka

PS - I think I have a Tech Bulletin for Bosch VE

Hi,
Does anyone have a list of what governor was used in which vehicle?

Had 2 P3s with a pneumatic governor. Also I believe the Matador came with one. Any others?

Can someone help me with a basic question? If I were the engine designer, what would govern my choice of governor?

Regards
Sutripta

P6 ( Perkins )

wild guess

1) load carrier or passenger carrier

2) genset engine or vehicular

3) altitude ? ( area of operation )

4) turbo or NA

Hi,
Functional requirements can be matched quite easily. But on what basis do I choose amongst mechanical, pneumatic, hydraulic, or electronic?

Hi,

If the engine has a capable ECU as well as reserve capacity to take in additional inputs, then I'd choose electronic.

I would choose hydraulic if it is possible to monitor the governor parameters using hydraulics [which i am not sure about ]

I will stay away from pneumatics unless the engine has a compressed air storage tank.

Guess the easiest is the mechanical governors that have been in use for ages.


The fastest response will be electronic and the slowest mechanical with hydraulics and pneumatics falling in between.

@ Sutrpta

another wild guess .

1) cetane No.

2) compression ratio

3) emission requirements

but why do we need a Governor if we have a max rpm stop screw in first place ? ( & a Idler too )

Diesels need a governor. It is even mentioned somewhere in the scans which Arka has posted.
Pre CRDi, it is built into the FIP.

If the engine has an ECU, you can bet there is a governor built in. It is just a software routine.

I was talking of non ECU engines.

The governor is selfcontained, and draws its power (and monitored speed) from some rotating shaft. The electronic one needs external electrical power. Having a non- self contained governor is an invitation to disaster, or a maintenance (and downtime) nightmare.

If I remember rightly, the VE had a hydraulic component. Waiting for Arka's scans.

Not as simple as that! Though discussing that here would be way off topic.
BTW, why is on the road performance of HPS better than EPS?!
