How does an LPG generator conversion work
An LPG (liquid propane gas) generator retrofit involves converting a gasoline generator to run on LPG petrol generator manufacturer. This usually involves installing a new carburetor designed for use with LPG and ensuring all of the generator’s seals and gaskets are compatible with LPG.Additionally, the generator’s air intake and fuel delivery systems may need modification. The conversion process typically involves:
●
Removing the generator’s existing carburetor and installing a new LPG-compatible carburetor.
● Ensuring all generator seals and gaskets are LPG compatible.
● Adjusting the generator’s air as needed and fuel system.
● It is worth noting that converting a generator from petrol to LPG should only be done by a qualified and expert technician as it can be very dangerous if done incorrectly.
With fuel prices on the rise, why not look for affordable alternatives?
Dual-fuel generators use both gasoline and natural gas. You are free to run your generator on natural gas or gasoline. You can easily change from one fuel to another simply by turning off one of the fuels. Dual-fuel carbs ensure you’re always with power no matter what happens.
Why switch to LPG?
We at BISON are big advocates for switching from petrol to LPG, whether a small generator or a slightly larger one. The substantial long-term benefits make the switch worthwhile.
a) Reduced costs
LPG has lower long-term costs for several reasons, including emissions and engine life.
b) Environment
LPG produces fewer emissions than gasoline and is more environmentally friendly.
c) Convenience
LPG is easier to transport and refill; switching to LPG also allows generators to produce less noise pollution as it is quieter.
d) Reliability
LPG generators tend to be more reliable than gasoline generators because they are less affected by issues like stale fuel or clogged carburetors.
Almost all small engines and generators can benefit from switching to LPG. Plus, it’s now easier than ever to make the switch.
In some areas, LPG is more readily available than gasoline, making it a more practical option for running a generator.
How to convert a gasoline generator to LPG
To convert a gasoline generator to LPG fuel, follow the steps below. Before starting, make sure you have all the necessary materials and tools.
a) Materials and tools required
LPG conversion kit (specific to your generator make and model)
Wrench set
Screwdriver set
Hose clamp
Pliers
b) Step-by-step instructions
● Safety First: Ensure the generator is turned off and disconnected from any power source before starting a conversion. Also, make sure the gas tank is empty.
● Remove the air filter: Locate the air filter housing on the generator and, depending on the fastener used, use a screwdriver or wrench to remove it. Store the screws or bolts safely, as you will need them later.
● Disconnect the carburetor: Use a wrench to disconnect the fuel line from the carburetor.
● Remove the bolts or screws holding the carburetor in place.
● Carefully remove the carburetor from the engine and set it aside.
● Installing an LPG conversion kit: An LPG conversion kit should include a regulator explicitly designed for your generator. Use the hardware provided to connect the conversion unit to the designated mounting location on the generator. Make sure the adjuster is securely fastened.
● Reinstall the air filter: Put the housing back in place and secure it with the original screws or bolts.
● Connect the LPG fuel tank: Follow the instructions included with the LPG conversion kit to connect the LPG fuel tank to the regulator. Make sure all connections are tight and secure.
● Test the generator: Turn on the LPG fuel supply and start the generator according to the manufacturer’s instructions. Check for leaks around the connections and listen for any unusual sounds. If everything works fine, you have successfully converted your gasoline generator to LPG fuel.
By following these steps, you will enjoy the benefits of LPG fuel, such as reduced emissions and lower fuel costs.
Dual fuel or LPG-only conversion?
On the surface, being able to run on natural gas or gasoline might seem like a desirable thing. However, examining the logic behind this assumption shows that it is flawed for most applications. Let’s say you operate primarily on LPG, and one day you run out of petrol. You have gas in the tank, so switch to gas operation until you get more. What’s wrong with this? First off, how long is the gas in the tank? If it’s been more than a few months old, it’s likely stopped being gasoline and turned into something like French Polish oil.
Gasoline degrades during storage as the more volatile elements evaporate, leaving a soup of less volatile components mixed with concentrated additives. This will have a lower calorific value than fresh gasoline, and the engine will not be able to produce full power. This degradation is accelerated by storing it in a vented oil tank above a hot engine. If the engine is not making full power, it will slow down under load. If the engine slows down under load, the fan that cools the alternator also slows down. See where this is going?
What if I use fresh gasoline from the tank? Well, that’s fine, but why would you want to carry a new can of gas with you instead of a spare bottle? In most cases, you will, of course, have an extra bottle of gas. If you only have one gas bottle, if at the end of the day’s use, you have less gas left in the bottle than you’ll need the next day, you’ll be forced to refill the bottle before it’s empty, wasting gas.
Dual fuel doesn’t add up at all. In most cases, the compromise in performance and the extra installation hassle are unjustified. The same logic behind a dual gas conversion, you can keep a horse in the back seat of your car in case you run out of gas. That’s what we did, but it was unpopular with passengers.
Impact of LPG conversion on machine life
When the gasoline engine expels the burned gas from the cylinder, it opens the exhaust valve, and the gas is removed from the exhaust port by the rising piston. When the exhaust valve is open, a small portion of the valve stem is exposed to the hot gasses, and any oil on it is evaporated. Gasoline contains additives that help improve the lubrication of this exposed part, while LPG does not. Therefore, LPG machines are likelier to wear the exhaust valve stem and its guides than gasoline engines. In an engine, the lubrication delivered to the valve gears is so abundant that wear is negligible. It may be worth adding an oil conditioner to help lubricate the valves. Regardless, the cost of replacing exhaust valves and valve guides is insignificant compared to the economics of running on LPG.
The additive system is designed to protect the valves from this extra wear, but in our opinion, the excess wear is so minimal that it can be safely discounted in most cases.
FAQs
1) Can you run a propane generator on natural gas without modification?
No, you cannot run a propane generator on natural gas without modifications. The two fuels have different characteristics, hoses, and slightly different engine settings for propane. Attempting to run a propane generator on natural gas without making the necessary modifications will simply not work at best and result in engine damage or even an explosion at worst. If you haven’t purchased a generator yet and are considering running on natural gas, propane, and gas, your best bet is a tri-fuel generator. Another option is to install a certified conversion kit on your generator.
2) Do generators run better on natural gas or propane?
Your requirements and circumstances will determine the answer to this question. Since propane has a higher energy density than natural gas, a generator powered by propane will provide a higher output than one powered by natural gas of the same size. Plus, it burns cleaner than natural gas and is more environmentally friendly. However, natural gas is generally less expensive than propane and is more common in urban areas. If you hook up your generator to a natural gas line, it will also be able to run continuously for extended periods.
3) How much power will a generator lose using natural gas?
Typically around 20% of efficiency is lost. The natural gas composition may vary. But it’s not an exact science, like choosing between an inverter generator and a regular generator. Inverters generate energy in different ways but also lose power, usually to a lesser extent. Natural gas is the most affordable alternative in cities, but you must consider the wattage you will lose.
4) What’s the fuel consumption of LPG-converted generators?
Each machine has slightly different characteristics, but as a rule of thumb, an LPG-converted machine will use 0.4 kg of LPG per kW/h of electricity generated.
