What Diesel Vehicles and Non-Road Equipment are CDPFs Suitable For? Full Application Scenario Guide

CDPFs (Catalytic Diesel Particulate Filters) are widely used across both on-road and off-road diesel-powered vehicles and equipment. Their high particle filtration efficiency and low-temperature passive regeneration make them ideal for operations with strict emission requirements, long idling periods, or harsh working environments.

✅ CDPF Applications – Main Vehicle and Equipment Types:

1. On-Road Diesel Vehicles:

• City buses (frequent idling, short-distance travel, prone to soot buildup)

• Long-haul trucks and heavy-duty transport vehicles

• Sanitation trucks, postal vehicles, refrigerated trucks

• Diesel vehicles being retrofitted to meet Euro V/VI from Euro III/IV

2. Off-Road Diesel Equipment:

• Construction Machinery: Excavators, wheel loaders, bulldozers, rollers

• Diesel Generators: Used for telecom stations, hospitals, construction sites

• Agricultural Machinery: Harvesters, tractors, pesticide sprayers

• Mining Equipment: Underground vehicles, drilling machines

• Port and Terminal Equipment: Container stackers, forklifts, trailers

✅ Scenario Analysis:

• Urban Low-Speed Driving: CDPFs can regenerate passively at lower exhaust temperatures, ideal for frequent stop-and-go conditions.

• Heavy-Load Continuous Operation: Stable high exhaust temperatures ensure consistent PM capture and regeneration.

• Indoor or Enclosed Environments: Such as mines or warehouses, where effective emission control is essential for worker safety.

• High-Regulation Zones: Like city centers, ecological zones, ports, and airports, where emission compliance is strictly enforced.
