Erayak 4500PD Not Starting with Pipeline Natural Gas? Here's Why and How to Fix It!

Issue Analysis: How Pipeline Natural Gas Affects 4500PD Startup

The startup issue with the 4500PD is often related to the difference in fuel supply pressures. In normal usage, we recommend using bottled natural gas in conjunction with our specialized standard gas hose fittings, which are equipped with a pressure regulator to stabilize the gas pressure at the rated 0.5PSI. This is critical for proper machine operation. However, when users connect the generator to household pipeline natural gas, the difference in gas pressure makes it significantly harder for the machine to start.

Gas Supply Pressure Differences

• Pipeline Natural Gas: Household pipeline gas pressure is generally lower, typically ranging from 0.25 PSI to 5 PSI, and the pressure fluctuates more, which hinders the efficient mixing of gas and air, making ignition difficult.
• Bottled Natural Gas: Bottled natural gas has a higher pressure, typically around 30–40 PSI, which ensures a steady gas flow, making it easier to ignite and ensuring smooth startup.

Starter Speed Differences

• Electric Start Version (4500PDE): The electric start provides a higher and more stable cranking speed, effectively compressing the fuel mixture for reliable ignition.
• Manual Start Version (4500PDM): The manual start has a slower and more inconsistent speed, which makes ignition harder, especially with low-pressure natural gas.

Fuel-Air Mixing Efficiency

• Low Pressure Conditions: Pipeline natural gas's lower pressure hinders efficient mixing of air and gas, affecting the concentration of the mixture and leading to ignition failure.
• High Pressure Conditions: Bottled natural gas's higher pressure ensures better mixing efficiency, helping to stabilize ignition.

Ignition System Requirements

For the 4500PD generator, the manual start version requires a higher concentration of fuel for successful ignition. Low-pressure natural gas increases the difficulty of ignition due to the insufficient fuel-air mixture.

Suggested Solutions

1. Choose the Electric Start Version: For users connecting to pipeline natural gas, we recommend the electric start version (4500PDE), as it performs better in low-pressure conditions and ensures a smoother startup.

2. Install a Pressure Regulator for Pipeline Gas: If you must connect to household pipeline gas, ensure the installation of a pressure regulator that stabilizes the gas pressure at 0.5PSI. This will ensure proper and steady fuel supply. High pressure (e.g., above 1 PSI) may cause gas to flow too quickly, making ignition impossible, while low pressure (e.g., below 0.5 PSI) will result in insufficient fuel and prevent startup.

3. Consult a Professional Technician: We advise users to consult a professional technician for pipeline natural gas installations to ensure proper pressure settings and safe connections to the 4500PD.
