Check diesel generator exhaust system scope before ordering by reviewing back pressure, silencer position, insulation, expansion joints, and wall or roof discharge.

What buyers should know first
The exhaust system is often split between generator supplier, installer, and civil contractor. If the RFQ only says exhaust pipe included, the buyer may miss back-pressure limits, insulation, flexible joints, silencer supports, roof flashing, or discharge direction.
For Yangzhou Tesla Power Equipment Co., Ltd. enquiries, the useful starting point is not only the engine brand. The purchaser should state the site load, duty rating, voltage, frequency, installation limits, control scope, and the documents expected with the quotation.
In practice
| Item to confirm | Why it matters | What to send with the RFQ |
|---|---|---|
| Back pressure | Too much restriction can affect engine operation. | Total pipe length, bends, silencer type, outlet route. |
| Thermal protection | Hot exhaust parts can damage cables or create safety risks. | Insulation requirement and clearance to nearby equipment. |
| Vibration movement | Rigid pipe connections can stress the engine outlet. | Flexible joint location and pipe support method. |
| Discharge point | Exhaust gas should not return to air intakes or occupied areas. | Wall or roof exit, rain cap, nearby openings. |
What to confirm before quotation
- Ask for the engine exhaust back-pressure limit for the proposed generator model.
- Separate supply scope for exhaust pipe, elbow, silencer, expansion joint, insulation, support, and rain cap.
- Check whether the silencer is residential, industrial, or project-specific.
- Confirm that exhaust outlet direction will not affect ventilation inlets, windows, or neighboring buildings.
- Include local fire and safety requirements in the installation review.
Common configuration mistakes
- Adding long exhaust runs after purchase without checking back pressure.
- Mounting the silencer directly on the engine without independent support where support is required.
- Leaving insulation out of the quotation in a tight generator room.
- Routing exhaust near the radiator outlet and creating hot air recirculation.
Documents to request
- Engine exhaust data and maximum back-pressure value.
- Exhaust layout drawing with pipe size, bends, and silencer location.
- Silencer datasheet and noise expectation.
- Installation responsibility matrix for pipe supports and wall openings.

Before requesting a quotation
Send the load list, required kW or kVA, voltage, phase, frequency, altitude, ambient temperature, duty rating, enclosure preference, ATS or paralleling requirement, fuel arrangement, and delivery destination. If the generator will feed emergency, medical, production, or data equipment, include the one-line diagram and the required handover tests.
Common questions
Can the exhaust pipe be extended after delivery?
It can be modified only after checking pipe size, length, bends, and back pressure against the engine data.
Is the silencer always included?
Many packages include a standard silencer, but type, attenuation level, supports, and installation accessories should be confirmed.
Why does insulation matter?
Insulation helps reduce surface temperature risk and heat load in the room, especially near cables and service walkways.
What should the RFQ drawing show?
Show generator position, exhaust route, wall or roof exit, nearby air intakes, and the expected silencer location.
