Injection Pump Govenor

Do you mean Yanmar sells an internal jerk style?

Can you just put any old external inline governor on?

Do you mean to speak with the fuel pump manufacturer?

Sorry for the questions... It's 1AM where I am right now and I've been up since 6AM yesterday. Babysitting an infusion... ZZZZZZZZZZZ

 

What on earth is going on here> whats a jerk style,-- you mean shuttle valve compared to rack.

 

http://en.wikipedia.org/wiki/Kugelfischer
its the German term ( they invented it )to describe a single unit operation as its quite common on single and 2 maybe 3+ cylinder engines where the pumps are individual units bolted straight to the block and hence the governer is inside the engine and supplied by the engine manufacturer as opposed to inline or rotary pumps fitted as accessory on the outside of an engine made by a 3rd party fuel pump company.

(Lets not add DD Cummins and Cat to this)

 

As far as I know none of the engine manufactures produce injector pumps. Injector pumps are specialized pieces of gear. Bosch and Stanadyne are the ones I come face to face with. I dont know how the pump governor actually works. When you remove an Injector pump for service , calibration, you always send it to a specialist. You should visit your local injector pump specialist and ask a few questions. Perhaps first find out who makes the pump on your diesel and do a bit of googling. Most service documents are on the internet with notations on calibration and terminology

 

FYI
here is a typical small engine with a single jerk style pump made by whoever but the govenor on page 62 is inside the engine

There is more injector styles and pumps than you could shake a stick at. Cummins for instance inject direct from the cam shaft with a common rail feed which is what the new Toyotas call there small truck motors.. One thing to remember there is nothing new anymore.

 

yes there is
what they call common rail these days meaning injection pressure is created by a single pump and a computer fires the injector ( assuming we are talking diesel)

So you can put a Jake brake on a toyota truck these days..amazing

 

A common rail just means a common pipe feeding along the engine to the injectors, nothing more but it sounds good in the brochure. Infact how else would you do it.

Similar bull shitty names Ram air, floor shift, selective control, mutiple speed , direct injection, etc etc

Three stage injectors now today, drible a bit in to start the fire then a bit more and then the full delivery,---all in a nano second ,-- mind blowing.

Wait till we get electronic valves and can switch from 2 stroke to 4 stroke from the drivers seat. variable lift , duration, timing , or none at all and no oil need up on the top as there is no cam shaft,--its on its way,--Bosch.

 

ya missed the point
there has never been until the last 10ish years, a system where injection pressure was in a common pipe and a computer fired the injector
that has replaced almost every other system on virtually every modern engine where they need to pass tough emission standards

 

True,-- but close.

Cummins had a common rail pressure variable delivery system but the injectors were fired from the cam.

Throttle position controled pressure pump/valve delivery. Only diff was the electronic injectors.

 

independant valves, Renault have a patent and a working system for F1 but was banned before ever used
Yes that will make the ultimate engine

 

NO the PT fuel system was low pressure ( say under 300psi), the injector pushed by the cam created the high injection pressure ( now 30,0000psi in a new common rail) as in all unit injector / cam fired style engines
Cummins did go partial electronic with their system called CELECT but it didnt cut it so now gone. 10 years ago
