What the heart is to the human body, the engine is to a machine, be it in a car or generator. Just as the heart has passages through which blood flows, so does the engine, with passages that allow for oil flow. This oil requires a certain optimum level of pressure to reach every part of the engine, and when the pressure required increases, you typically encounter a situation of high oil pressure.
In this detailed guide, you'll understand what causes high oil pressure, its causes, and how to solve it. However, dealing with traditional generators for your backup power supply inevitably leads to issues, whereas Jackery Solar Generators offer a reliable, safer, and quieter alternative that can charge most household appliances.
Key Takeaways
Here are a few key details to help you understand the essentials:
- High oil pressure occurs when the engine's oil pressure is above the optimal range's upper limit.
- It can be caused by a failed oil pump, blockages in the oil filter, and low lubricant levels, among other things.
- Diesel generators require regular maintenance and upkeep to ensure optimal oil pressure.
- Solar generators, on the other hand, don't rely on oil and require minimal upkeep.
What is the High Oil Pressure of a Diesel Generator?
The oil pressure in a diesel engine or generator indicates the amount of resistance the oil faces as it flows through the various passages. Oil pressure is typically measured using the unit “PSI” or “Bar” and varies between 25 and 65 PSI.
This pressure level is critical for the oil to reach every part of the engine and is called the “normal oil pressure.” Situations such as high, low, or no oil pressure are all relative to the pressure within the generator, as you'll see below:
- High Oil Pressure: This occurs when the oil pressure indicated on the pressure gauge exceeds the upper limit of the optimal range, suggesting a potential obstruction to the oil flow.
- Low Oil Pressure:Low oil pressure occurs when the oil pressure falls below the lower limit of the optimal range, preventing oil from reaching all the parts of the engine.
- No Oil Pressure:If the oil pressure gauge or the oil pump is damaged, there is no pressure within the engine to keep it lubricated.
For several reasons, oil pressure is crucial to running a diesel engine or generator. Optimum oil pressure levels are critical to ensuring the engine is always well-lubricated. If an engine suffers from low oil pressure, oil doesn't flow to all parts, and the engine could seize.
Here are a few reasons why oil pressure is critical to a diesel engine's functioning:
- It ensures that an engine runs smoothly over longer durations.
- It keeps unlubricated metal surfaces from coming in direct contact with one another. The friction caused often leads to the engine wearing out quicker.
- In extreme cases, it prevents the engine from failing or seizing due to excessive friction.
Signs of High Oil Pressure
Diesel engines, like any other, have ways of warning you that the oil pressure in them might be too high. Here are a few signs or symptoms you can look out for to gauge whether your engine oil pressure might be too high:
Oil Pressure Gauge Indicates High Oil Pressure
The first sign that the oil pressure in your diesel generator or engine might be too high is that the gauge gives you a higher reading than usual. The indicator typically shows the range within which the oil pressure is normal, so a higher reading can indicate a problem.
Ticking or Knocking Sounds
High oil pressure indicates that the engine has to exert more pressure to have the engine oil reach every passage to lubricate it. If, for example, the oil doesn't lubricate your engine well, you'll notice it making ticking, whirring, or knocking sounds due to the friction caused. This is another sign that your diesel generator's oil pressure might be too high.
Oil Leaks
If you notice oil leaks from your diesel generator, chances are the oil pressure is too high. The engine exerts greater pressure to ensure the oil flow, leading to leaks via the gaskets or seals.
Smoke Coming From the Exhaust
Efficient diesel engines are designed to emit minimal exhaust smoke. However, if you notice your exhaust emitting black smoke, the oil is burning in the combustion chamber due to high oil pressure.
Causes and Solutions for High Oil Pressure
Once you've identified the signs that the oil pressure in your diesel generator might be too high, you must understand what causes it and how you can fix it. This section explains the primary causes of high oil pressure and their solutions.
Low Lubricant Levels
Low lubricant levels are among the most common causes of high oil pressure. An engine with less than normal lubricant levels works harder to compensate for its reduction, resulting in high-pressure levels to ensure every engine passage is well lubricated.
Solution: Regularly check the amount of lubricant in your generator to ensure it doesn't fall below the optimum level.
Contaminated Oil Filter
The essential purpose of an oil filter is to remove any contaminants the oil or lubricant might have, such as metal particles or carbon residue. However, the oil filter can get clogged over time, especially if it isn't routinely replaced during a service. Black smoke from your generator's exhaust is a sign that your oil filter might need replacing.
Solution: Follow the generator's service guidelines and ensure that the oil filter is replaced based on the interval mentioned in the user manual.
Blocked Oil Passages In the Engine
Blocked oil passages create a barrier to the free flow of oil through the engine, which often increases oil pressure.
Solution: Remove the oil pan and brush away any accumulated sludge or debris. Do this routinely to ensure the oil passages remain free of obstructions and maintain optimum oil pressure levels.
Incorrect Oil Grade or Viscosity
Engine oils come in varying grades and viscosities, which are determined by the temperatures at which they operate. Thinner oils perform better in places with colder temperatures, whereas thicker oils perform better in warmer conditions.
Similarly, the oil used must also be of the right grade (blended, synthetic, and so on). If the oil's viscosity or grade is incorrect, your engine will have to exert higher pressure to ensure it remains lubricated.
Solution: Always ensure that the engine oil you use complies with the specifications in the generator's user manual to ensure optimal oil pressure levels.
Causes and Solutions for Low Oil Pressure
Just like a diesel generator can suffer from high oil pressure, it can often also face a situation in which its pressure levels drop below the optimal minimum. This section explores the key causes of low oil pressure in diesel engines and what you can do to fix them.
Oil Pump Worn Out
When your diesel engine wears out, the internal leakage of the oil pump's internal gear increases. When the gasket at the filter collector is worn out, this leads to low pressure due to an improper seal.
Solution: Check the oil pump and replace the seals and gaskets to ensure the oil pressure remains at optimal levels.
Oil Leakage
If you notice an oil leakage in your diesel generator, this could cause lower oil pressure. Leakages typically happen due to excessive wear and tear and increased clearance in the crankshaft or the camshaft. This clearance ultimately leads to oil leaking, reducing the overall pressure and affecting the engine's ability to lubricate all its components.
Solution: Regular servicing or maintenance of your generator is key to identifying wear and increased clearances that could lead to oil leakages. Take your generator to a dedicated service center to have all its components checked and any worn-out seals and gaskets replaced.
Blocked Oil Filter
The oil filter in your diesel generator must be regularly cleaned or replaced, lest you increase the chances of debris blocking the filter altogether. This can often lead to a reduction in the oil pressure, resulting in inefficient lubrication.
Solution: Ensure you replace your generator's oil filter based on the interval mentioned in the product's user manual. In the short term, buy a new oil filter and replace it with the old one to ensure a clean passageway for the oil to flow.
Pressure Limiting Valve Incorrectly Adjusted
The key role of the pressure limiting valve is to moderate the oil pressure flowing through the engine's components. If the spring force of this valve is either too small or entirely broken due to increased wear, the oil pressure will reduce.
Solution: It is crucial to regularly clean the pressure-limiting valve to remove debris. If a spring breaks, it must be replaced immediately.
Causes and Solutions for No Oil Pressure
While diesel generators are often prone to high or low oil pressure, they can encounter situations with no oil pressure. When there is no oil pressure, the gauge indicates a pressure of 0 PSI. This section lists some key reasons this might happen, along with their respective solutions.
Oil Pressure Gauge is Broken
A broken oil pressure gauge is unable to show the correct oil pressure reading. If it shows an oil pressure reading that's either too high or 0, this could mean the gauge is broken and needs to be replaced.
Solution: You can check if the gauge is broken by loosening the pipe joint of the oil pressure gauge. If pressure oil leaks out, you can be sure the gauge is damaged. You can take the generator to a service center to have the gauge replaced or buy one and do it yourself.
Damaged Oil Pump
A diesel generator that hasn't been serviced or maintained in a long time will experience immense wear. This wear can also damage the oil pump, resulting in no oil pressure.
Solution: Get your diesel generator serviced immediately to fix any components that have worn out, and replace the oil pump with a new one.
Alternatives for Diesel Generators
Like any car, diesel generators require regular maintenance and servicing. Continuous neglect can lead to a range of problems, including either very high or very low oil pressure. Incorrect oil pressure in a diesel generator can quicken its engine's wear and tear. If this issue is not addressed for a prolonged period, it could lead to the generator seizing entirely.
While diesel generators can be handy solutions for backup power supply, they have their fair share of downsides. Some of these include:
- They require regular maintenance to ensure their components aren't worn out, leading to oil pressure issues, among other problems.
- They're noisy and thus not suitable for indoor use.
- They emit harmful emissions and must be stored and used outdoors.
- They're more expensive when compared to alternatives like gasoline or portable generators.
You will likely encounter several options if you're in the market for a backup power supply solution. Depending on the scale of use, these could include portable, gasoline, inverter, or solar generators. However, each one has its pros and cons.
