Turbocharger Assembly 3620846 for Caterpillar 3512 & 3516 Engines

The Caterpillar 3512/3516 Engine Turbocharger Assembly 3620846 is a high-performance turbocharger component specifically designed for the Caterpillar 3512 and 3516 engine series.

I. Product Overview

Model: 3620846

Brand: Caterpillar

Applicable Engine Models: Caterpillar 3512, 3516

Type: Turbocharger Assembly

II. Structure and Function

The Caterpillar 3512/3516 Engine Turbocharger Assembly 3620846 primarily consists of components such as the turbine, compressor, bearings, and intercooler. These components work together to achieve the following functions:

Turbine Section: Composed of a turbine housing and turbine rotor, it is driven to rotate at high speed by high-temperature, high-pressure exhaust gases.

Compressor Section: Consists of a compressor housing and compressor rotor. The rotation of the turbine rotor drives the compressor rotor to rotate at high speed, thereby compressing the air entering the engine and increasing the intake pressure.

Bearing Section: Supports the high-speed rotation of the turbine rotor and compressor rotor, ensuring their stable operation.

Intercooler: Used to reduce the temperature of the compressed air, preventing excessively high intake air temperature from affecting the engine.

III. Working Principle

The working principle of the Caterpillar 3512/3516 Engine Turbocharger Assembly 3620846 is mainly based on waste heat energy recovery and air compression technology. When the engine is operating, high-temperature, high-pressure exhaust gases pass through the turbine section, driving the turbine rotor to rotate at high speed. The rotation of the turbine rotor drives the compressor rotor to rotate at high speed, thereby compressing the air entering the engine. The compressed air enters the intercooler for cooling before entering the engine combustion chamber, increasing the intake pressure and air density of the engine, thereby increasing the engine's power and torque.
