Bi-fuel vehicles are those that can run on two types of fuel, typically gasoline and a volatile alternative fuel such as natural gas, LPG, or hydrogen. The two fuels are stored in separate tanks and the engine runs on one fuel at a time, with the driver able to switch between the two fuels manually or automatically. Bi-fuel vehicles are a type of hybrid vehicle, and they offer several benefits over traditional single-fuel engines, including reduced running costs, greater fuel efficiency, and lower emissions.

Bi-fuel cars are vehicles with multi-fuel engines capable of running on two fuels
Bi-fuel cars can switch between the two fuels manually or automatically. The driver can select the fuel type through a dashboard switch. Bi-fuel engines are also capable of running on only one fuel source if the other is not available, although they will operate less efficiently. Bi-fuel engines always use the most efficient fuel for the task, making them more efficient than single-fuel engines.
Bi-fuel cars are affordable, easy to operate, and offer significant fuel cost savings compared to petrol. They are also environmentally friendly, offering a cleaner alternative fuel option. Bi-fuel cars are particularly popular in Europe, with Poland, the Netherlands, the Baltic states, and Italy having many cars running on LPG or CNG. Dacia, for example, offers a range of bi-fuel vehicles, including the Sandero, Logan, and Duster models.

The two fuels are stored in separate tanks and the engine runs on one fuel at a time
Bi-fuel vehicles are those that can run on two different types of fuel. The two fuels are stored in separate tanks and the engine runs on one fuel at a time. The driver can switch between the two fuels manually or automatically. This is in contrast to a dual-fuel system, which uses two types of fuel at the same time in a mixture.
Bi-fuel vehicles are a more efficient option than single-fuel vehicles, as they allow the user to choose the most efficient fuel for the task at hand. They also streamline fuel storage, reducing the number of fill-ups required and the size of necessary storage tanks.
Bi-fuel vehicles typically burn gasoline and a volatile alternative fuel, such as natural gas (CNG), LPG, or hydrogen. LPG is a combination of propane and butane, added to an existing petrol engine by integrating a separate injection system. LPG is stored in a dedicated tank that is pressure-resistant and specially built to store the liquid. LPG engines are affordable, easy to operate, and offer fuel cost savings of more than 40% compared to petrol.
The conversion of a standard gasoline vehicle to a bi-fuel vehicle typically involves installing a gas cylinder in the trunk and an LPG or CNG injection system and electronics. This conversion is possible because the gases can use the spark-ignition of a gasoline engine. Diesel engines, on the other hand, are compression ignition engines and do not have spark plugs, requiring more extensive modifications to run on alternative fuels.

Bi-fuel engines allow the driver to switch between the two fuels at will
Bi-fuel vehicles are those that are equipped with engines capable of running on two different types of fuel. The two fuels are stored in separate tanks and the engine runs on one fuel at a time. Bi-fuel vehicles can switch between the two fuels, either manually or automatically.
The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG), followed by natural gas (CNG). LPG is a combination of propane and butane, added to an existing petrol engine by integrating a dedicated injection system and tank. LPG engines are affordable, easy to operate, and have larger fuel tanks than their petrol counterparts.
Dual-mode cars, such as the E85 compatible vehicle, are designed so that if one fuel source is exhausted, the engine can continue to run on the other fuel source. This is achieved through a dual-fuel system, which uses a mixture of two types of fuel at the same time. For example, a dual-fuel engine might start with one type of fuel, and then gradually add the secondary fuel source until the optimal mixture of the two fuels is achieved for efficient running.

Bi-fuel cars are more efficient to run compared to single-fuel engines
Bi-fuel cars are vehicles with multifuel engines capable of running on two different types of fuel. The two fuels are stored in separate tanks and the engine runs on one fuel at a time. Bi-fuel cars can switch between the two fuels manually or automatically. This is in contrast to dual-fuel vehicles, which must burn both fuels in combination.
Bi-fuel engines also offer cost savings of up to 50% when compared to a single-fuel system. For example, LPG fuel is cheaper than petrol, with an average price of £0.60/L. Bi-fuel technology can provide fuel cost savings of more than 40% compared to petrol. Bi-fuel engines also have larger fuel tanks, which result in longer runtimes. During extended power outages, operators can keep critical applications running longer by not being so dependent on diesel fuel.
Bi-fuel engines also offer flexibility in terms of fuel choices. For example, a dual-fuel engine can allow the use of alternative fuels such as sewage gas or landfill gas, paired with a more traditional fuel. This is especially useful in the trucking and busing industries, where dual-fuel vehicles are popular, typically combining diesel and natural gas for a dependable, economical solution. The most efficient use of fuels within this type of engine is a mix of 75% natural gas to 25% diesel fuel.
Bi-fuel engines also have benefits in terms of fuel storage and maintenance. Dual-fuel engines eliminate the need for large-scale on-site storage of expensive fuels such as diesel. They also lower the maintenance costs associated with diesel storage.

Bi-fuel cars are affordable, easy to operate, and have a larger fuel tank capacity
Bi-fuel cars are an affordable option for those looking to reduce running costs without compromising on quality. For example, LPG fuel is much cheaper than petrol, with an average price of £0.60/L. Bi-fuel technology provides fuel cost savings of more than 40% compared to petrol. The switch from petrol to LPG can be done manually or automatically when the LPG tank is empty.
Bi-fuel cars are also easy to operate. The LPG tank is located in place of the spare wheel and does not reduce the available interior space or boot volume. Filling the tank takes just 2 minutes, and you can easily alternate between combustion and LPG with the flick of a switch.
Bi-fuel cars have larger fuel tank capacities than their petrol-only counterparts. For example, the All-New Sandero/Stepway has a 50L/40L filling capacity + 50L petrol and 84L on the Duster (34 LPG + 50L petrol) compared to just one 50L tank for a petrol version.
Bi-fuel cars have multifuel engines capable of running on two fuels, with the engine running on one fuel at a time. The two fuels are stored in separate tanks and the car can switch between them manually or automatically. This is different from a dual-fuel vehicle, which must burn both fuels in combination.

Frequently asked questions
Bi-fuel cars are vehicles with multifuel engines capable of running on two fuels, such as petrol and LPG (liquefied petroleum gas). The two fuels are stored in separate tanks and the engine runs on one fuel at a time.
Bi-fuel cars are more efficient than single-fuel engines as they always use the most efficient fuel for the task at hand. They are also more environmentally friendly, with LPG being a cleaner alternative to petrol. Additionally, LPG is cheaper than petrol, with an average price of £0.60/L, resulting in fuel cost savings of more than 40% compared to petrol.
The switch between the two fuels can be done either manually or automatically (when one of the tanks is empty). A dedicated gauge helps monitor the tank levels and displays the remaining driving range.
Examples of bi-fuel cars include the Dacia Sandero, Logan, and Duster.
One potential drawback is the limited infrastructure for LPG refueling in certain countries. For example, there are only around 1,200 LPG fueling stations in the UK, compared to 8,000 standard petrol stations. However, LPG-powered cars are still quite popular in Europe.
