СЕРДЕЧНИК В СБОРЕ ОХЛАДИТЕЛЯ Caterpillar 5428990

An Aftercooler Core reduces the temperature of compressed air before it enters the engine, allowing denser air to support better combustion efficiency. Lowering the air temperature helps improve fuel usage, supports stable power output, and reduces the chances of overheating during continuous operation. The cooling process enhances air quality entering the combustion chamber, leading to smoother operation and improved overall performance, and also helps maintain controlled thermal conditions within the engine.Attributes:• Limits debris presence with a maximum allowed weight of 25 milligram.• Controls maximum particle size to 3.175 mm within internal surfaces and openings.• Maintains a maximum particle area of 2.58 square mm for cleanliness standards.• Core uses an aluminum single‑row tube‑fin design with 12.7 fins per inch air fins.• Turbulator density is specified as 20.32 fins per inch.Applications: An Aftercooler Core is located in the intake air system between the air compression stage and the engine intake and cools the compressed air before entering the engine to improve combustion efficiency.
