[color=#000099][/color]Heavy-duty truck mechanic/engineer on trucks and diesel engine diagnosing issues

Turbocharger Malfunction :

BELOW IS A TROUBLESHOOTING TO HELP DIAGNOSE SOME DIESEL ISSUE ENGINE NOT STARTING CAUSES : Flate Battery Glowplug or relay Faulty Insufficient fuel supply Blocked fuel supply filter Faulty diesel injector faulty high presure fuel pump low compression injector blow by seat leaking when all this are all checked and they are all ok then finally it has : Internal engine problem such as: Piston,lose and check top cylinder improper valve seating

For lattest trucks that are have electronic engine and transmission like international trucks 2000-4000 series and other lattest trucks we include this when diagnosing. Faulty pressure Regulator sensor ,cam-crank sensor,EGR problem,ECU(electronic control unit) or PCM(powertrain control module)

THE ANSWER IS THE SMOKE:
We can generally understand what is wrong with a diesel engine by the colour of smoke emitted from the exhaust. There are three basic colours ,black,white and blue BLACK SMOKE
This is due to a air to fuel ratio inbalance,either the fuel system is delivering too much fuel into the engine or there is not enough clean air(oxygen)a few things to look for- (1)faulty injector (2 )faulty injector pump (3)dirty air cleaner (4)turbocharger or intercooler faulty (5)problem with cylinder head,valve clogged due to faulty Egr(exhaust gas recycling unit )

There is money in the field as an entrepreneur in automobile engineering.i see plp flag how to use diagnosing tools up and down but when you call them to program ECM or PCM(powetrain control module) or chip tuning,that is when we differentiate the boys from the men bt if you can much money and contract for you.you will make it faster as a heavy-duty trucks diagnoser than in small car bt the softwares are very expensive ranging from 400,000-6000,000 naira just google search; the learning process and repair process is very difficult Bt if you know glory be to God.example when you diagnose and find a code( 223) in international truck.code meaning :vehicle personality module(vpm) not communicating with electronic control module (ecm).then what will you do?.Can you see that the truck life is in your hand.

If you ve car repair issues both small,heavy-duty trucks,excavator issue just post it then we combat the issue and give you a remedy

In this new generation erra the labour market is becoming stuffy,the unemployment rate is increasing.when you graduate from university to the labour market no one cares who you are,you show the outside world who you think you are; by your skills.the reason i set this trend is for young plp to gain some experience on heavy-duty truck,because i ve learnt alot from nairaland it was in this forum i learnt how to register as a vendor/contractor in an oil/servicing company which i taught it was only for government connected big shot guy bt with help of nairalander it was very simple.my very first contract from oil serve in portharcourt to service a spoilt truck was with the knowledge i got from nairaland.so i will be updating this trend on issues on heavy-duty trucks repair and maintenance.

What a nice trend but i guess non mechanic engineer can blend up

Yes@holajeedayy ,it is an entrepreneurship post for both mechanic and non mechanic for diversification of income, so as to know how to use auto diagnostic scanner to find fault in vehicles and how to repair

Boss can i have your number or we chat better on whatapp 07030842589

@holadidayy Pls visit my facebook page at Heavy-duty trucks mechanic/technician/engineers,then reply back to me ;it is to prepare your mind a little bit.

i couldnt see a nigerian page there.

Just search for heavy-duty truck mechanic/technicians /engineer that is my page the page explains some mechanical topic and terminology,and finally i dont know what u mean by nigeria page

Let first start by answering your question by it terminology you said a wachia cng engine i believe it means:wachia compressed natural gas engine (2) you said when it reaches 1700 rpm it Increases by it self to 2200
OPINION:it can be caused by faulty(1) Governor:A vital component of all diesel engine is a mechanical or electronic Governor which regulate the idling speed and maximum speed of the engine by controlling the rate of fuel delivery without a govern or faulty govern cannot have a stable idling speed and can easily overspeed.(2) faulty ECU/ECM (3)i will like to know where this engine is used if it is used in a generator,truck,marine or where.thanks

Can i learn in your ph workshop?

Can i learn in your ph workshop?
Also what i mean be nigeria page is that the pages are open be white engr
