Best dual fuel Generators are devices used to supply electrical power to appliances or machines. They convert mechanical energy into electrical energy. The mechanical energy is obtained from external sources such as engines powered by gasoline, liquid propane, natural gas, diesel, etc.
It is important to understand that the generators do not create electricity, but supply the mechanical energy that forces the movement of electrons or particles carrying the charge that we call electricity through the wires in the circuit.
Simplifying it further, let us compare the electrical charge to water. The water is there in a pipe or a reservoir. All we do is force the water to flow by applying mechanical force. This force is the push that sets the flow of water into motion. The mechanical force may be in the form of gravity or pedalling of the water wheel.
How Does a Generator Work?
All generators work on the principle of Electromagnetic Induction mathematically described by James Maxwell and proven experimentally by Michael Faraday. Thus electromagnetic induction is the push induced by a magnetic field in an electrical conductor such as a wire. This push is called an electromotive force or voltage. This voltage sets off a cascade of electrons in the wire which we use as electricity.
This initial push is generated by the generators. The mechanical energy is provided by the fuels you use to run the engine. In the case of dual fuel generators, propane or LNG and air laden with oxygen are drawn into the cylinder. This process is like the one that occurs in a spark ignited engine.
The only difference is that theair-fuel ratio is lesser than in a carburetor. Near the end of the compression, stroke gasoline is injected causing the LNG to burn.
Best dual fuel generators can be fuelled 100 percent on gasoline or in a mixture with natural gas. On both, the modes the power density, transient response and torque curve are maintained.
Best Dual Fuel Generators Uses
Generators power anything that runs on electricity. They are an independent or standalone supply of electricity. And can be used anywhere as they are portable. They are usually used as standby or backup power supply in the event of a power outage. They can also be used for convenience or recreation while camping or partying at a remote location where there is no access to grid electricity.
Considering the greenhouse effect and global warming it is in our favour to use fuels such as natural gas that burn completely. As they burn completely they do not let out residues such as soot, etc.
Also, the calorific value of the fuel makes up for the carbon dioxide emitted, thereby reducing the carbon footprint.Oil and gas are the largest cost of operation. The fuel efficiency of the latest generation of generators allows for an impressive cost reduction. Further, the abundance of natural gas and the expansion of its production have brought down the fuel costs.Besides the integrated controls of these generators have optimized the substitution rate and an automatic and seamless transition between the gasoline and dual fuel modeshave increased the fuel efficiency.
Substitution rate is a critical parameter for dual fuel operation where a portion of the total energy is provided by LNG. Higher the substitution rates the higher the savings on fuel costs. The dual fuel generators are required to meet the compression ignition emission regulations with an oxidation catalyst to lower non-methane hydrocarbon(NMHC) and carbon monoxide (CO) emissions. The ability to function 100% on the two modes offers flexibility depending on the availability of the fuels. You can even switch the fuel whilst the generator is operating. Last but on the least, in the event of fuel shortage one fuel can be substituted for another.
Types of Best Dual Fuel Generators
There are various kinds of generators such as the EMD or Electro-Motive Diesel generators. EMDs are minimal risk and maintenance-free generators with a low RPM rate.Then there are diesel generators,these are a combination of a diesel engine and electrical generator plus an alternator used for peak lopping, exporting electricity and grid support.
The third kind is the portable generators. These are generators on wheels that run on gasoline. And the last type is the natural gas generators that generate 20 – 2500 KW of electricity depending on their size that ranges from 150 – 4000 HP. The dual fuel generators are a combination of the last two types – gasoline and natural gas generators. The functioning of these generators has been explained above.
There are other dual fuel generators classified based on the fuel they use. The diesel generators can use 80% diesel and 20% biodiesel reducing emissions and our dependence on fossil fuels. Emulsified diesel uses a small amount of water mixed with diesel to improve the thermal efficiency and reduce exhaust emissions.( We have also reviewed the Τop Best 15 Inverter Generators in 2020).
The features to look for on a dual fuel generator are aheavy-duty frame with four-point rubber mounts. These offers anchorage and a quiet vibration-freeoperation.It should have a set of wheels and handles that make it easy to move around or portable.
There should bean electric start and a recoil rope start system. As the name suggests the gensetshould run on two fuels. The usual choice of the customers is the gasoline and propane generator. But there are generators that run on diesel in combination with other fuels. The fuel tanks capacity should be able to support 8 hours of running time at a 50% load capacity.
A7-horsepower engine with cast iron sleeves should allow the genset to produce 3850 watts of power continuously and should be able to surge up by another 1000 watts.
It should have a 12-volt DC outlet to charge the batteries.There should be safety sensor such as low oil shut off sensors, voltage guard, etc. The design andproduction should be EPA approved. And last but not the least, the product should come with a year’s warranty.
Characteristics of Best Dual Fuel Generators
The characteristics to look for are the cost-effectiveness and ease of use. This means it should be easy to crank up and be portable. It should be environmentally friendly and meet the industry standards and regulations.
The generator should have features that help control and modulate the flow of the fuel sand safety shutdowns in the event of a leak. The gen set should be able to run 100% on one type of fuel until both are replenished, making the generator dependable in all conditions.It should be constructed of a tough material so that it can withstand extreme climate conditions.
The design should be supplemented with safety features such as toggle switches, low oil sensors, volt guard, temperature sensors to increase the efficiency of the generator. There should be temperature, Hertz and time gauges to monitor these functions of the generator.It should have a capacity to generate enormous amounts of electricity and powerful enough to work for long hours. The safety features and gauges should be able to support and monitor the power needs of a wide range of tools and appliances without harming their circuits.

Low Fuel Shut Off
It’s an amazing feature that can protect your appliances from all types of damages. The generator starts fluctuating when the fuel ends in the generator. It may cause some serious damage to your appliances. But the Low Fuel Shut Off feature can save you by automatically turning off the generator when the fuel level is low.
12 Hours Operation
Now, that’s something we really liked about this generator. It can accommodate your electricity needs for almost 12 hours when the tank is full. It means you’d get enough time to complete your tasks rather than worrying about filling in the fuel tank again and gain.
Electric Push Start
Starting a generator can be a huge pain in the neck if it doesn’t come with the electric push start feature. With this feature, you can start the generator with your finger. The generator comes with a battery that sends electric current into the engine when you press the start button. The battery needs to be replaced after a year or so.
Pulsar G12KBN is a heavy-duty generator that can accommodate your electricity needs in case of a power outage. Dual Fuel Capacity and Electric Push Start are the most remarkable features of this generator that make it prominent among others. Pulsar G12KBN can serve you for years if you pay proper attention to its maintenance.
