This post will introduce the working principle and components of diesel engine cooling system in detail. It is worth taking a few time to read it.
Diesel engines are heat-generating sources. They are cooled by circulating a water-based coolant through a water jacket, which is part of the engine. The coolant is circulated through pipes to the radiator to remove the heat added to the coolant by the engine and then back to the engine.

Piston rings seal the combustion chamber. They are set with precision so as to apply the correct pressure on the cylinder wall or liner, which ensures there is a consistent film of oil across the cylinder's working surfaces. This provides sufficient lubrication and protects against wear.
Piston rings from Perkins come as three rings. They are the top compression ring, then the intermediate compression ring and finally the oil control ring. These parts are relatively small in size but play a large role in the main cylinder block of your engine.

Many of our kits include reagent bottles for steeping and storing bitters. This type of bottle has been used to store chemicals for at least 150 years, though the idea for the ground glass stopper dates back to the late 1700s. The combination of glass bottle and stopper makes the container very resistant to chemical corrosion with a few exceptions. Very strong alkali should not be stored in these bottles because the alkali can cause the stopper to corrode and fuse to the neck of the bottle.

Are Composition Shingles and Asphalt Shingles the Same Thing?
The roofing industry is full of different names and terms that are hard to understand as a homeowner. This can be confusing and often frustrating.
Especially when different roofing contractors use different terms to mean the same thing. This brings us to a commonly asked question, “Are composition shingles and asphalt shingles the same thing?”

Are You Storing Food Safely?
Whether putting food in the refrigerator, the freezer, or the cupboard, you have plenty of opportunities to prevent foodborne illnesses.
The goal is to keep yourself and others from being sickened by microorganisms such as Salmonella, E. coli O157:H7, and C. botulinum, which causes botulism. Keeping foods chilled at proper temperatures is one of the best ways to prevent or slow the growth of these bacteria.
