Troubleshooting Diesel Engine Cooling System

Cooling System for an engine is one of the most important parts. Each engine has its own cooling system. We use different cooling system for different engine. Water cooling, Oil cooling, Air cooling is most common cooling system. In this post I will discuss about the Diesel Engine Generator Water cooling system. If we burn diesel inside the engine then it will become hot. For this reason we use water inside the engine and it reduces engine inner temperature. This method name is Jacket Water Cooling System. Let ’ s learn more about this cooling system. Jacket Water Cooling System is normally two types: – a) Open Circuit Cooling System b) Close Circuit Cooling System.     Open Circuit Cooling System: Usually in this method the engine is cooled by water from the external source like ponds or water tanks.     Close Circuit Cooling System: In this method the water reserved inside the engine and the radiator or a heat exchanger is used to...

Diesel Engine Abnormal Noise, Smoke And Oil Pressure

With each new light on the dash, we hold our breath as the thought of expensive bills flashes through our minds. As a car owner, preventative engine maintenance  is one of the most important things you can do to keep your vehicle healthy and your wallet happy. Although it ’ s not always black and white when it comes to our finely tuned machines, technicians at Milex Complete Auto Care share some of the more obvious signs that your vehicle may be experiencing engine damage. Check Engine Light You may be patiently waiting in the carpool line when an immediate anxious moment hits every vehicle owner; your check engine light illuminates. We all know that dreadful feeling when our stomach sinks and we can only hope the light is informing us of a loose gas cap. As unnerving as it may be, an illuminated check engine light is a useful tool to inform you of potential engine trouble. Although issues may range in severity, it is always a good idea to have your vehicle serviced f...

Troubleshoot Overheating Issue For Diesel Engine

1) Inspect the Coolant Level: The most obvious system to inspect upon discovering overheating issue is the coolant level. If the coolant is too low this can allow pockets of air into cooling system. When air gets into the cooling system it will cause a reduction of coolant flow due to the presence of air bubbles. Air flow alone isn ’ t going to get the job done to keep engine temperatures constant. If you find coolant levels to be too low simply add more coolant to the engine. Other causes of air bubbles is the deterioration of the cylinder liner. When the combustion cycle occurs it causes tremendous pressures up to 65,000 psi with in the cylinder liner. Over thousands of hours of operation, upon combustion, the liner beings to vibrate violently within the engine block injecting air back into the cooling system. These tiny bubbles can then do damage to the liner in the form of pitting (cavitation) and eventually eat away the liner all the way to the cylinder bore. T...

Fuel Injector Information and Maintenance

What is a diesel engine fuel injector? What are the benefits of a diesel engine fuel injector? How does a diesel engine fuel injector work, what makes it fail, and how difficult is it to maintain? These are important questions to every owner of a diesel engine . The diesel engine fuel injector is actually what separates it from average gas engines and is the most complex aspect of the diesel engine. So, let ’ s start off with the basics. Gas engines use port injection or a carburetor to inject fuel before the intake stroke. This occurs outside the cylinder. What this means is gas engines load fuel into the cylinder during the compression and intake stroke phase all at once. It the compression of the fuel and air mixture is compressed too much, it ignites and causes a sort of knocking to the engine, creating excessive heat and damaging the system. This is where diesel engines differ significantly. A diesel engine uses a fuel injector to directly inject the fuel into the cy...
