812W06100-0004/3 Intercooler

The Intercooler 812W06100-0004/3 is a specialized charge air cooler assembly designed for heavy-duty trucks such as the Sinotruk SITRAK C7H and Howo T7H. As a crucial component of the turbocharged engine system, it serves vital functions.

Product Function

1.Core Cooling Function

The primary function of the intercooler is to reduce the temperature of the hot, compressed intake air. After air is compressed by the turbocharger, its temperature rises significantly, and its density decreases. The intercooler cools this hot air through heat dissipation, thereby increasing air density and intake volume, which enhances engine power.

2.Heat Exchange Efficiency Optimization

The intercooler features an advanced cooling fin design. It directs the compressed air through numerous small tubes while ambient cold air from the front of the vehicle flows over fins connected to these tubes, effectively cooling the compressed air. This design can typically provide an additional 5%-10% power increase.

3.Pressure Loss Control

While ensuring excellent cooling capacity, the product focuses on minimizing pressure drop. By optimizing the design of the tubes and fins, it achieves a balance between suppressing pressure loss and improving cooling efficiency, ensuring high heat exchange performance without creating excessive air flow resistance.

Main Purpose

1.Engine Performance Enhancement

The intercooler is primarily used to improve the volumetric efficiency of turbocharged engines. Data shows that for the same air-fuel ratio, a 10°C drop in intake air temperature can increase engine power by 3%-5%. Lowering intake temperature also reduces fuel consumption and improves the engine's adaptability to high altitudes.

2.Preventing Engine Issues

Uncooled, hot compressed air entering the combustion chamber can lead to excessively high combustion temperatures, causing problems like knocking. This intercooler effectively lowers the intake air temperature, preventing engine knock and reducing NOx emissions, thereby lowering air pollution.

3.High-Altitude Adaptation

At high altitudes, using an intercooler allows for the use of a compressor with a higher pressure ratio, enabling the engine to produce more power and improving vehicle adaptability. This product ensures the engine can maintain stable power output at high altitudes for normal vehicle operation.
