Q: What is the difference between active and passive regeneration in diesel exhaust purification equipment?
A: Passive regeneration relies on elevated exhaust temperatures and specific NOx/PM ratios to burn off soot, which limits its effectiveness during low-load operation or cold starts . Active regeneration, featured in our Diesel Exhaust Purification Equipment, uses electric heaters to initiate cleaning regardless of engine operating conditions, ensuring reliable performance even with intermittent use .

Q: Can this equipment be used for both stationary generators and mobile diesel engines?
A: Yes. Our Diesel Exhaust Purification Equipment is suitable for a wide range of applications including diesel generators, forklifts, excavators, loaders, and other mobile equipment . Custom mounting configurations are available for different installation requirements.

Q: How often does the DPF filter need cleaning or replacement?
A: With active regeneration, the system automatically cleans itself during operation, typically requiring minimal manual intervention. The filter elements themselves have a service life of 3-5 years depending on usage intensity and fuel quality . Manual cleaning may be required if the diesel fuel quality is poor or if the engine has high oil consumption .

Q: What is the back pressure impact on engine performance?
A: Our Diesel Exhaust Purification Equipment is engineered to maintain average back pressure well below engine manufacturers' specifications, ensuring no negative effect on engine performance . The large filtration area and optimized flow path minimize pressure drop while maintaining high filtration efficiency.

Q: Is this system suitable for indoor use in manufacturing facilities?
A: Absolutely. This Diesel Exhaust Purification Equipment is ideal for indoor applications such as warehouse forklifts, indoor generator sets, and manufacturing plants where exhaust emissions must be controlled for worker safety and regulatory compliance . The high-efficiency filtration significantly reduces exposure to harmful diesel particulates and gases.

Q: What maintenance does this diesel exhaust purification equipment require?
A: Maintenance requirements are minimal. The active regeneration system handles routine cleaning automatically . Recommended maintenance includes visual inspection every 1000 operating hours , periodic checking of electrical connections, and filter replacement at the end of service life. For applications with poor fuel quality, occasional manual cleaning with compressed air may be necessary .
