idle problem??

Forum: 

what could be a problem with my rocky: when the engine warms up the rpm doesnt come down after reaching 2500 rpm!!! i have to use bigger gear to lover the rpm to 2100 and then it lowers to normal 700. Please, please help me Wink

Is your accelerator cable kin

Is your accelerator cable kinked or sticking?

no, all visible parts are mov

no, all visible parts are moving o.k. and even when the rpm stucks into 2500 the visible lever in the diesel pump goes back into normal idle level. it got worse when i added the "feed" (gives more diesel while stepping on it) in the beginning it got stuck all the time but now only when the engine starts to warm up.

Then it may be fuel pump sett

Then it may be fuel pump setting, but it seems strange if it has just started to happen suddenly.

Look at the rear of the fuel pump. There is a small bolt with a locknut, and locking wire. Break the wire, hold the bolt with a screwdriver or spanner, undo the locknut, and carefully unscrew the bolt about 1/8 turn. Tighten locknut. Repeat if necessary, but somehow remember what the original setting was, in case this is not the problem.
Do this carefully, big changes happen with very small adjustments of this setting.

Cheers

do you mean the "full load st

do you mean the "full load stopper", because that is the screw that i tightened a 10 decrees to get a bit more power after installing 31" tyres.. the problem got worse then.. first when the problem started i added 2-stroke oil into diesel and it stopped.. former owner propably used Soviet diesel and it is dry.. it feels as there is some sort of worn bit where it stucks cause while turning left it also releases the rpm to normal..

Id guess thats the one. I hav

Id guess thats the one. I havent heard it called a full load stopper, but having played with mine previously, I found it affects idle speed dramatically.

yes thats it.. i had to adjus

yes thats it.. i had to adjust idle also after playing with that.. someone said it might be ruptured diaphram (?) in the pump.. anyone know if it is hard to change..

i would say the movement you

i would say the movement you have made on the injector pump governer screw has caused your problem!
I would also say that the pump now needs to be setup correctly and this would need to be done by someone thats knows EXACTLY what there are doing!
seen people blow engines up messing with this screw, so wouldnt hesitate to take the truck to the mechanic you trust!

anyone wana ride in my hovercraft!

The car is merely for offroad

The car is merely for offroading and getting to work, so i wouldnt want to spend too much money on it. and when i started this i asked someone i trust if it can harm the car and he said no. it only pushes more diesel into the engine, so it runs on rich if i stand on the accelerator all the time. but now i can reach the normal high speed with the tyres.. i asked how much it would cost to repair it in a local dieselspecialist and i propably could find a good spareparts car with the amount.. so i'm looking for a more fun and less costly way to fix the problem. but seems like i need to take the car to the mechanic

not sure its gona be that cos

not sure its gona be that costly unless there is a problem with the pump!
diesels are tricky, due to the fact then run purely on the compression of the fuel, to little fuel or to much fuel with too little air or too much air can cause running problems!
if you put more fuel in and not more air, then the engine could bog out, as the ratio's would be wrong! similarly if you dont change the air filter regularly and it dont get enough air the engine will run rich and burn more fuel, for the same HP output!
it might not be such a big deal for a mechanic to set it up properly again! they have the kit to ascertain if all the fuel is being burnt or too much fuel as the case maybe!

tell you what i would try! take the airfilter element out and see what happens, as you have got more fuel in there perhaps it needs more air! if thats the case put on an induction kit LOL! Smile

i marked the old setting to t

i marked the old setting to the srew so i can put it back and propably the problem will go away, BUT (!!!!!!) the i'll be with the same problem: lack of power. with the one cylinder lacking compression a bit (not consuming oil), i need more power to "keep rollin'" with my 31" saharas. (Exellent offroad tyres :unpaid advertisement:) with only that 10 degree turn i got back to normal highway speed wcich is max speed for my rocky. and my "friend" turned the same srew (with turbo engine) and no problem at all so something is broken. but i'll set the old settings and then you need to tell me how to get more power out of my 2,8 dl Wink

all engines are the same real

all engines are the same really mate! i tune the engine on my hovercraft and have messed about with a few cars in my time!

the point i was trying to make was, that if you want more power without the engine bogging out, then just more fuel (which adjusting the governer screw will do) is not enough. you also need to get more air into the engine!
if i wanted to get more hp out any engine the first thing would be a induction type air intake, then i would put on a different exhaust, then start playing with the fuel ratios.
putting on a tuned exhaust, or zorst with more back pressure and a induction intake could add several (if not more) hp to the engine!

point taken

yes i noticed as soon as i did the adjustments that i needed to use the pedal slowly as when there was too much diesel going in it slowed the acceleration. and i dont think the engine will survive adding a turbo. i have to look up what the things you mentioned are because english is not my native tongue. someone said that diesel engine should have as straight as possible exhaust and no resistance in flow at all.. so should i put as big pipe as possible.. and what is the induction intake?? and i will see what the mechanic sais about my dieselpump. and thank you a lot for your input on the problem..

im no expert on exhausts, the

im no expert on exhausts, there must been tuned exhaust available for this type of engine, will have a look on the net and see if i can find you something! its tricky you have to get the expansion area correct i.e. just increaseing or decreasing the size might not have the desired effect, it should be calculated!
regards an induction kit, its a means of getting crap loads more air into the engine, you take off the current air filter, and fit a straigh bit of pipe with a sodding great K & N air filter on the end, this will suck loads more air into the engine! not quite like having a turbo but can be very effective!
again will see if there is such a thing for this type of engine about Smile

THANK YOU! And a deep bow ;)

THANK YOU! And a deep bow Wink I'm a beginner in this 4x4 tuning and rocky is a tricky one because we don't have anyone importing it anymore Sad everyone is driving toyotas but mine is more fun! and with old one you can experiment without too much headache if something goes wrong. And with 31" sahara's and toyota mechanical winch rocky is a beast! only if there were diff locks!!!

well unless anyone knows any

well unless anyone knows any different it appears you cant get induction kits or tuned zorsts for a 2.8d fourtrak???
a k & N filter element would help i suspect, as would opening the size of the airfilter intake so more air can get in!
i might experiment with some alu pipe and a old k & n filter i have from my hovercraft to see how this effect performance!
will let you know what i find out!

i will also talk to the guy that made tune pipes for my hovercraft rotax engine and see what he says!

cheers

Hi revving idle speed

Modern engines, diesel and petrol, have automatic monitoring of the fuel input. Various conditions are measured by sensors: such as rpm, engine temp, manifold vacuum, accelerator position. Whereas those were once sensed by simple mechanical gadgets, today much of the monitoring is communicated along insulated copper wires with neat little slide plugs/ sockets. With brassy contact surfaces. Which are not usually serviced.

The engine bay is a very hot dirty environment. Some engine problems may arise from corroded contact, a well known fact re the battery terminals.

When idle or starting or other engine performance parameters are bad, a first step for this driver, is to wiggle each of the plug/ socket connectors..... in my experience this may greatly improve matters.
