How do you maintain a Perkins engine?


Maintaining your Perkins engine is the key to its optimum performance. Slight changes in performance can easily go un-noticed, often a drop of 20% in performance can happen before the operator notices. Missing service intervals can lead to reduction in performance, let alone the worst case of a vital part failing.

Each engine supplied comes with a detailed list of checks for you to carry out at set intervals.The performance checks required will vary buy engine type and operating conditions, so it is wise to ensure the checks and frequency are right for your engine.

The regular checks that you need to carry out fall into daily and weekly categories, along with regular servicing and others at various specified intervals. They all have the same aim of ensuring that your engine runs as long as possible at the maximum efficiency. No two schedules are exactly the same, so you should always check the schedule for your particular engine.

Every Perkins engine has its own maintenance schedule.
It’s also worth noting that the checks either relate to the calendar time or the hours your engine has been running. Checks should take place far more often on an engine in almost constant use than for one used occasionally. So, for example, changing the cooling system engine coolant is recommended every two years – but it will need attention sooner if your engine runs for 3,000 hours, which is the equivalent of running 24/7 for just over four months.

Remember, the daily checks are just as important as the regular servicing

Daily checks include:

Cooling system coolant level
Driven equipment
The engine air cleaner service
Engine air pre-cleaner, cleaning it if necessary
Engine oil level
Fuel system primary filter/water separator
V-belts
Walk-around inspection
Every 50 service hours or weekly checks include:

Fuel tank water and sediment, draining if necessary

Its has become imperative that much informations about diesel generator and their simple maintenance techniques and safety tips are so scarce in this platform. So, I decided to be of an helping hand to those who are of need.

Erratic power supply or total darkness in Nigeria is not news any more. Most homes,businesses and manufacturing industries all relied on alternative source of power supply to run their machines. This machine cost lot of money, also, needs adequate attention and knowledge. So,feel free to post your technical questions, enquiery, maintenance tips, overhauling,electrical faults etc here.

Engine oil deterioration causes and preventive measures


Engine oil cooling, lubrication, cleaning, sealing function, the quality of oil is directly related to engine performance. With the increase in working hours of the engine oil due to high temperature oxidation, corrosion and other mechanical parts wear material and fuel vapor factors to be contaminated, in addition, the engine oil also contains a certain amount of consumption in normal use. To regularly check the oil level and the level of contamination, to ensure that the engine in good operating conditions.
An oil deterioration Cause Analysis
(1) cooling water to seep oil
When the diesel engine appeared wet perforated liner, cylinder liner sealing water ring damage, damage to the oil cooler, cylinder head gasket is damaged, the cylinder head damage and other reasons, the cooling water will enter the oil so that oil emulsion deterioration. This situation can be observed coolant is abnormal excessive consumption of oil to determine whether phenomena such as moisture content of emulsion.
Oil containing water, will accelerate sludge formation, oil the tarnished deterioration (commonly known as aging), weakening of antioxidant resistance and dispersion properties of the additives.

2) crankcase vent bad air resistance.
When the diesel engine work, there will always be part of the combustible gas and exhaust gas into the crankcase by the clearance of the piston rings and cylinder walls, if the serious damage of piston rings, this phenomenon will be more serious. Fuel vapor to condense into the crankcase will dilute the oil, acid and water vapor in the exhaust gas will corrode the parts, and leads not gradually diluted, aging, and coke, so that the engine oil performance deterioration. In addition, elevated temperature and pressure of gas will allow the box to enter the crankcase, resulting in the exudation of oil from the oil seals, gaskets, etc.; due to the reciprocating motion of the piston, the gas pressure of the crankcase cyclical changes, the impact launched working properly, serious cause in the crankcase of oil and sneaked into the combustion chamber and cylinder cover. To this end, the ad hoc diesel engine through the trachea (breathing tube), both within and outside the crankcase pressure is in equilibrium, thus prolonging the duration of use of the oil. When the crankcase vent bad air resistance will accelerate the oxidative deterioration of oil.
(3) diesel engine to overheat.
Engine overheating the main reason for the cooling water within the scale too much in the cooling system, water pump failure of the cooling water cycle interrupt, clogged radiator, bad radiator cap and thermostat, fan belt too loose or broken, the hot season load long run, the combustion chamber of carbon deposition and lubricating oil system, oil is insufficient as a result. When the engine overheating will cause the oil temperature, thus speeding up the aging of the oil deterioration.
Engine oil at high temperature under high pressure, the deterioration of its anti-oxidation stability, exacerbated by thermal decomposition, oxidation and polymerization process. In the case of high temperature, oil and incomplete combustion product of condensation of water vapor and dust entrained in the intake mixture will cause the oil deterioration accelerated.
(4) improper maintenance of diesel engines.
When changing the oil, if cleaning the lubrication system or no serious cleaning crankcase oil filter or oil cooler cleaning is not thorough or drain installed oil filter gasket, the diesel engine by adding new oil, even time is short (only a few hours), also make the oil re-residual contamination seriously polluted, thus accelerating the deterioration of oil.

(5) diesel engines use gasoline engine oil.
The diesel engine compression ratio is 2 times more than the gasoline engine, the main parts of the high temperature and pressure impact than the gasoline engine is much larger, and thus the production of materials in some parts is different. For example, the gasoline engine main bearing and connecting rod bearings available material is relatively soft, good corrosion resistance babbitt to make diesel engine bearing lead bronze or lead alloy and high-performance materials must be used to make, but the corrosion of these materials performance is poor.

6) The mixed use of different grades of engine oil.
Various grades of oil, in addition to their different viscosity grades, the chemical composition of different, mainly is composed of oil additives and quantities. Under normal circumstances, the variety and quality grade of oil is classified in accordance with the type and quantity of the additive composition, because different types of additives and chemical properties are different, so different types of oil additives can not be mixed, otherwise you can make the oil additives react chemically, so that the use of oil performance degradation, accelerated deterioration.
(7) oil grade used improperly.
Due to a variety of different types of diesel engine work, technical condition and performance requirements, the requirements of the choice of oil grade is not the same. If the oil used by the diesel engine is not required, will result in not working properly, leading to accelerated oil deterioration.


2, measures of prevention of oil deterioration

(1) always check the oil level of oil.
This check should be before the diesel engine start or stop 10min until 10min to check the oil level again. Supplementary oil should pay strict attention to clean and check for leakage.
(2) regular checks of the quality of the oil.
Check the oil level, check the engine oil should pay attention to pollution levels, oil should not be on the Dipstick color (oil) black phenomenon phenomenon. When the oil reached the interval mileage oil change indicator, it is timely to replace oil. Multi-grade oils tend to darken when in use, is a normal phenomenon. Commonly used method to check the engine oil quality: comparison of traces of oil, viscosity tests and assays, such as several.

Today, we shall discuss the correlation and different between various generator set.

For point of note, the most common generator sets such as Mikano, FG Wilson, Jubaili, Marapco, Shark, Demba etc all have same engine which is Perkins engine. That implies that they uses same engine parts. Their only different is the name printed on the soundproof. This how that comes to possibility. The named generator brands don't manufacture generator, they only obtain the license or go into trade deal to assemble the parts which they import from Perkins in UK. Perkins Engines are manufacture in UK not Nigeria. So, these companies only construct the soundproof that houses the Perkins engines.

In simple language, Mikano 20 kvA has same engine has 20 kvA FG Wilson, Marapco and the rest.

The only difference of note is the Electrical component of the generator. A generator is divided into mechanical and electrical components. So, the electrical component that has the alternator differs from brand to brand. But, hardly do they have fault once they are well protected from water intrusion.

Mantrac generator are manufacture and assembled by CAT ie caterpillar. Mantrac carries caterpillars engine and quite different from Perkins.

Cummis generator are manufacture in
