How To Use An Engineering Compass

Cummins Incorporated produces various types of diesel fuel engines that have a wide multifariousness of uses. It has made significant improvements over the years to become one of the world's largest manufacturers of diesel engines. Like every auto, they come with their share of problems. For instance, not properly servicing a lacking engine causes internal combustion and ruins your entire machine. Moreover, when your Cummins fuel injection pump malfunctions, you take to either cheque fuel delivery system or supervene upon the injection pump. Here are some of the most common troubleshooting information to assistance y'all solve certain Cummins engine issues.

Fuel System

Since all diesel engines are bailiwick to fuel arrangement problems, it'south of import to confirm your fuel quality. If your vehicle was running fine until yous last fueled it, you should doubtable fuel contamination as it tends to dull downwards or stop the motor. Moreover, if your engine is losing power especially in the cold season, you need to add No. 1 diesel fuel or an anti-gel additive. This is because diesel engines often gel-up at temperature beneath 10 degrees F making information technology hard to kickoff your engine.

Ensure that the injection organization is clean to supply each cylinder with the right amount of fuel. Inspect the various injector lines for damage and ensure that they aren't tight at the cylinder head. If your truck starts normally only has low power, check the fuel pump. Search for loose wires or a broken fuse. If these aren't the problem, accept the fuel pump output tested past a professional.

Cummins diesel engine must e'er have a good supply of air. An engine with depression ability over a period of fourth dimension might be having an issue with its air delivery system. Ensure that the air intake systems don't accept excessive dirt or debris. A sporadic hissing or metal noises from the turbocharger too as a respective drop in engine power indicates that your turbocharger is declining.

Low Cranking Speed

Vehicles that are turning over slowly have hard starting problems as a result of Cummins fuel injection pump declining to generate enough fuel pressure to initialize fuel injection. Low cranking speed is more than common during the colder season of the twelvemonth as a consequence of a dead or faulty battery. Ensure that you change your battery as before long as possible to avoid being stranded in the center of nowhere.

Diesel Cam Sensor

The Cam or crank sensor is a vital role in all Cummins engine. Ensure that it's not cracked, damaged or loose and if in doubt, modify the sensor as they are affordable and volition help you check out different problems related to your engine.

Blue Smoke From Your Diesel Exhaust

Blue smoke indicates that your diesel Cummin'southward engine is burning engine oil. There are other reasons that might suggest why your engine is emitting blue smoke like:

Worn-out piston rings or cylinders
Faulty diesel fuel lift pump
Faulty valve stem seals
As well much engine oil in your motorcar

White Fume From Your Diesel Exhaust

When white smoke is emitted from the exhaust, information technology indicates that the diesel fuel injected into your cylinders is not burning correctly. Information technology can besides issue from:

Fuel starvation to the pump leading to incorrect performance of the fuel pumps timing
Petrol or water contamination in your diesel fuel
Low engine compression
Engine timing out

Black Fume From Your Diesel Exhaust

Black fume results from an imbalance in air to fuel ratio. This imbalance occurs when too much fuel is being delivered into the engine by the diesel fuel organization or there'south non enough air. This smoke can also be caused by:

A faulty diesel pump
Dirty air filter
Faulty turbochargers or intercooler
Clogged valves within cylinder caput due to a faulty EGR
