mit. storm fuel pump modification
Posted 06 November 2004 - 10:06 PM
the car is black smoke, without activate the evo-mode system, i can see
from the side mirror that the black smoke comes out so frequently, if with
the evo-mode, no any motorcyclist dare to ride behind my car. my friend's
storm facing the same problem too. i heard from some ppl that with the fuel
pump be modified, it will reduce black smoke and also improve the power of
the car, and the cost is below RM2,000. wonder here anybody has already
done this to his or her storm, how is the performance and black smoke
thanks for sharing

Black smoke is a perrenial issue affecting diesel rig owners, but it can
be minimised using the recommended methods below :
1. Always replace the air filter and the diesel filter frequently.
2. Do not baby your engine. Most diesel rigs spend most of the time
idling in urban stop/start crawl. This causes the soot to accumulate in
the exhaust system. Give it some good highway (max torque + max rev)
trashing once a week.
3. Change your driving pattern, do not "put the boot in" when using the
accelerator, instead let the engine rev freely without suddenly
depressing the go pedal all the way while driving.
4. Finally keep the black smoke down by performing the free "Italian Tune-
Up" once a week to keep the horses alert and ready
* Your results might vary - make sure the timing belt is in good
condition and the engine state of tune (fuel pump and others) in good

Some have tried playing with the EGR.
use a plate that blocks the EGR valve or,
stuff a ball bearing that locates in the vacumn pipe to the EGR valve.
Both claim to be all singing and dancing.
basically if you use the blanking plate method you wont need to use a
ballbearing. the bearing is just a snide way of blocking the egr valves
vacuum pipe when done like that the EGR stuck in the closed position. if
you use a plate tho its completely blocked.
You will ended up with more NOx and less soot. JPJ so far only check the
particulate at the exhaust end.

the time even though I did a soot cleaning at the SC. I suspect the fuel
pump is the culprit. Thought of reducing the black smoke by adjusting the
fuel pump accordingly. SC told me servcing the fuel pump cost at least

only mean incomplete combustion. Most likely causes are either lack of
oxgyen or excessive fuel delivery or poor injector spray pattern.
Before sending fuel pump for expensive service, get the workshop to take
out the injector and check the spary pattern.

black smoke, my guess is either excessive fuel delivery, compromising the
fuel/air ratio or faulty injectors. I'll look at the fuel/air ratio first
before changing the injectors.

if you have one on your engine. Try the ball bearing method first or just
pull the vacuum hose connected to the EGR. It will only take a minute to do it.
If you want to see what a EGR looks like or how to use the ball bearing,

similar with a hand pump on top. dunno what is it!
curious, wanna try it.

The Ranger/Fighter turbo diesels (pre-egr) models, well, did not come
with the EGR system. Just the plain plumbing-no egr hoses are seen.
the hand pump thingamagic is the diesel fuel filter housing. The hand
pump is used to prime the fuel filter after diesel filter change/water
you should perform the Italian Tune-Up frequently to eliminate the black
smoke on these kind of engines.

BTW what is the Italian Tune-Up?
I am thinking that there must an adjustable nut or something in that
nature that i can adjust the fuel pump on the ranger so that the ratio
of fuel can be adjusted. what is your comments on this? Do you know where
is the adjustable nut?
I know Volvo FL10 lorries fuel pump can be adjsuted to reduce black smoke
from incomplete combustion.
