The search for economical and environmentally friendly transport is becoming increasingly relevant for owners looking to reduce operating costs. In this context, branded cars ŠkodaThe plants equipped with the factory liquefied natural gas (CNG) power supply system occupy a special niche. The integration of gas equipment ensures reliability, which is difficult to achieve with self-installation.
Many motorists mistakenly believe that gas is a compromise in terms of dynamics and comfort. However, the modern TGI engines developed by the Czech concern refute this myth. You get a car that does not require modifications, retains a full dealer warranty and is ready to work in any climatic conditions immediately after purchase.
Owners who have chosen Škoda In methane, they get a unique combination of environmental friendliness and practicality. The factory system allows the use of both gasoline and gas, switching between them automatically depending on the fuel level. This solution is ideal for those who travel a lot in the city, but sometimes travel outside of settlements where infrastructure may be poorly developed.
Advantages of the TGI Factory Gas System
The main difference between TGI-labeled cars is that engineers Škoda The engine and body were adapted to the specific requirements of methane. Unlike converted cars, the load-bearing structure of the body does not suffer here, and the cylinders are integrated into the design so as to minimize the loss of useful luggage volume.
Safety is a priority when developing such models. The system is equipped with a variety of sensors that monitor the pressure, temperature and integrity of pipelines. In case of an emergency, the valves automatically shut off the gas supply, and the system instantly switches to gasoline. This eliminates the risk of leakage or explosion, which is often a concern for garage plant owners.
The economic benefits are obvious even at current fuel prices. The cost of one cubic meter of methane is much lower than the price of a liter of gasoline, which reduces the cost of refueling in two or more times. With active operation, the difference in the budget becomes significant after a few months of car ownership.

Technical features and system design
The system is based on the use of compressed natural gas, which is stored in special cylinders under high pressure. The pressure in cylinders can reach 200 bar, which requires the use of particularly durable materials such as composites or special steels. This ensures long service life and fuel storage safety.
The evaporator gearbox plays a key role in the operation of the entire system. It lowers the gas pressure to the working level and heats it, turning it from a liquid state into a gaseous state before being fed into the engine. This process occurs automatically and unnoticed by the driver, ensuring a stable fuel supply.
The system is controlled through an electronic unit that is integrated into the overall network of the car. The unit analyzes data from oxygen sensors, throttle position and pressure in the fuel ramp, adjusting the ignition advance angle to optimize methane combustion.
During operation, it is important to monitor the level of fuel. A separate indicator is displayed in the dashboard showing the amount of gas. When the gas runs out, the system smoothly switches to gasoline, and the driver receives a notification on the display of the onboard computer.
- 🔋 Cylinders undergo hydraulic tests at a pressure of 150% of the worker
- 🌡️ The reducer uses the heat of the coolant to heat the gas.
- 💻 The engine ECU adapts to the octane number of the gas (about 110)
What happens at low temperatures?
At temperatures below -10°C, the evaporation of the gas can slow down, which requires additional heating of the gearbox. In the factory systems, an additional circuit of antifreeze circulation is provided, which guarantees stable operation even in severe frosts.
The system also includes an emergency pressure relief valve. In the event of a fire or overheating of the cylinder, this valve opens, releasing the gas outwards through a special tube located away from the body of the car, preventing an explosion.
Economic feasibility and payback
Calculation of the return on methane depends on the annual mileage. For drivers who travel more than 30,000 km per year, the difference in fuel costs becomes apparent in the first year of operation. Methane costs on average 2-2.5 times cheaper than gasoline, which with large volumes allows you to save tens of thousands of rubles annually.
However, it is worth considering the initial cost of the car. Models with a factory TGI installation often cost 15-20% more than conventional gasoline versions. This is due to the more complex design of the engine, the presence of expensive cylinders and specific electronics. Recovery is achieved by reducing operating costs.
In addition to direct savings on fuel, owners of such cars can claim tax benefits in some regions. The lower emissions of harmful substances make such cars attractive to city authorities, who may offer discounts on parking or exemption from the transport tax.
When reselling a car, its cost can also be higher than its counterparts on gasoline, especially in regions with a developed network of gas refueling stations. Buyers are often willing to pay extra for a ready-made, certified system, not wanting to waste time and money on the installation of handicraft equipment.
| Parameter | Gasoline | Methane (CNG) |
|---|---|---|
| Fuel cost (conditionally) | 55 rub/liter | 22 rub/cube. |
| Consumption (mixed cycle) | 7.5 l/100 km | 9.0 cubic metres/100 km |
| Operating costs | High | Low |
| CO2 emissions | High | Average |
| Range (gasoline + gas) | 600 km | 900 km |
⚠️ Payback figures are averaged and may vary depending on current fuel prices in your area and driving style. Do not forget to include in the calculation the cost of scheduled maintenance of the gas system.
The payback of the factory gas system comes faster with large mileage, but requires an initial investment in the purchase of a more expensive model.
Infrastructure and availability of refuelling
The development of a gas refueling network is the main factor influencing the choice of a methane-powered car. In the major cities of Russia and Europe, the network of AGNKS (automotive gas filling compressor stations) is well developed. You can find a gas station in almost every area of the metropolis.
However, when planning long trips, it is necessary to study the map of gas station locations in advance. In remote regions or on some routes, the distance between stations may exceed 150-200 km, which requires careful route planning. In such cases, having a gasoline reserve becomes critical.
Modern navigation systems Škoda often have built-in search functions for gas stations, including gas stations. This allows the driver to see the nearest stations directly on the multimedia system screen, without resorting to using third-party applications.
The cost of servicing a CNG filling station is also worth considering. Methane refueling is typically faster than propane-butane refueling due to more automated processes. However, not all stations are equipped with modern dispensers capable of working with high pressure, so it is worth choosing proven networks.
- 🗺️ Use the navigator with the "Methane" filter to plan routes
- 📉 The range on gas is usually 300-400 km depending on the volume of the cylinders
- ⛽ Combined mode allows you to refuel anywhere there is gasoline
Save a list of verified gas stations in your navigator in advance, especially if you are planning a trip to a new region, to avoid downtime along the way.
Maintenance and safety
Servicing a car with a factory TGI system does not require any special difficulties, but has its own specific nuances. The main task is to regularly check the tightness of connections and the condition of the cylinders. This must be carried out by certified services that have a license to work with gas equipment.
An important step is replacing the fuel filter and checking the performance of the gearbox. Contaminants in the gas can cause injector failure or engine instability. It is also necessary to monitor the level of antifreeze, as it is used to heat the gas in the reducer.
The frequency of replacing gas filters is usually 30,000 - 40,000 km. This depends on the quality of the fuel at gas stations and operating conditions. Ignoring this procedure may result in a clogged throttle valve and loss of engine power.
Cylinders have a service life determined by the manufacturer and are subject to mandatory recertification. This usually happens once every 5 years. After the expiration date, cylinders must be replaced with new ones to ensure safe operation.
☑️ Scheduled maintenance of the gas system
If a malfunction occurs with the gas system, the on-board computer will display an appropriate error. In most cases, the car will automatically switch to gasoline, allowing you to drive to the service without risk.
Prospects for the development of CNG technologies at Škoda
Volkswagen Group, to which it belongs Škoda, actively invests in the development of technologies for the use of alternative fuels. Despite the global trend towards electrification, methane remains an important transition solution, especially for commercial vehicles and taxis.
New models with improved efficiency of TGI engines are expected to appear in the future. Engineers are working to increase power and reduce fuel consumption to make gas even more competitive with diesel and gasoline.
Infrastructure development also plays a key role. Governments in many countries are encouraging the construction of new CNG filling stations, which makes the use of methane more accessible to ordinary drivers. This creates a favorable environment for the growing popularity of such cars.
Even in the era of electric vehicles, Škoda methane-powered vehicles maintain their position as a reliable and economical option for those who are not ready to switch to electricity or need a car with a long range without dependence on charging stations.
