Functional Benefits
The assembly detects negative pressure changes in real-time, converts physical pressure into electrical signals for the engine control unit (ECU), and monitors air filter condition. The integrated air filter effectively removes dust and impurities, ensuring clean air enters the engine to prevent component wear and improve combustion efficiency.
Quality Assurance
Each unit undergoes rigorous factory testing including dimensional accuracy, detection precision, filtration efficiency, sealing performance, and high-low temperature resistance tests. This ensures OEM-grade quality standards and reliable performance in demanding bus applications.
Installation Guidance
For optimal performance: Install in correct direction and position aligned with air intake pipeline and filter base. Use qualified personnel familiar with safety practices. Clean installation interfaces before assembly. Use matching fasteners for secure fixation. Avoid over-tightening and protect from impact during installation.
