FAQs on Sinotruk Howo CNG Parts

1. What is the recommended replacement cycle for CNG filters?
High-pressure CNG Parts filters: every 10,000-20,000 km; low-pressure filters every 10,000-15,000 km. In dusty environments, reduce interval by 30%.

2. Are Howo CNG Parts compatible with other truck brands?
While precision-engineered for Sinotruk Howo, many components (valves, fittings, PRVs) follow universal ISO 15500 standards and can be adapted to compatible CNG systems – consult our technical team.

3. Do you offer warranty on CNG parts?
Yes, manufacturer warranty up to 2 years or 100,000 km (whichever first) on major CNG Parts including cylinders, ECUs, regulators, and injectors.

4. How to detect a leaking CNG injector?
Use diagnostic ECU for fuel trim deviations or apply soapy water to injector seals. We provide step-by-step leak-check guidance with every part shipment.

5. What is the service life of Howo CNG cylinders?
Our type-4 carbon-fiber cylinders offer a 15-year service life with mandatory hydrostatic testing every 5 years (per ECE R110). All cylinders come with traceable serial numbers.

6. Can I upgrade my diesel Howo truck to CNG using these parts?
Sinotruk Howo CNG Parts are primarily for OEM CNG models, but complete conversion kits (ECU, injectors, cylinders, regulators) are available for approved retrofits – contact our engineering support.

7. How do I verify genuine Sinotruk Howo CNG Parts?
Authentic CNG Parts feature a QR-coded hologram label and serial number on each component. Verify directly on our official portal or request batch certificates.

8. What preventive maintenance extends CNG parts life?
Regularly inspect high-pressure hoses every 6 months, change coalescing filters annually, and recalibrate ECU after 50,000 km. Following these steps ensures CNG Parts reach maximum design life.

Troubleshooting & Solutions for CNG Parts

Engine power loss & poor acceleration
→ Clogged high-pressure filter: replace sintered filter element (5-10μm).
→ Also check for restricted CNG injectors; clean or replace if flow is below spec.

Gas smell inside cabin or near engine bay
→ Loose high-pressure fittings: retorque using calibrated wrench to manufacturer specs.
→ Inspect and replace worn PTFE sealing washers or O-rings immediately.

Hard starting or extended crank on CNG mode
→ Faulty gas temperature sensor or incorrect coolant temperature input – recalibrate ECU.
→ Verify rail pressure; replace low-pressure regulator diaphragm if unstable.

Excessive valve / clicking noise from injectors
→ Worn CNG injector poppet or sticky solenoid – ultrasonic cleaning or replacement.
→ Incorrect rail pressure (too high) – adjust 2nd stage regulator to 0.8-1.2bar.

Fuel gauge shows incorrect gas level
→ Pressure/level sensor drift – recalibrate or replace sensor (4-20mA output).
→ Also check wiring harness to CNG ECU for intermittent connection.

Engine stalls when switching to CNG
→ ECU parameters out of range: perform adaptation reset with diagnostic tool.
→ Verify gas quality: low methane content may cause misfire; drain any oil carryover from filter.
