Electronics, software

The emulator is installed in vehicles for which the fuel level indicator does not show correctly after installation. This means that the gas control unit thinks that it is running on petrol and the fuel is running low on the display, even though the petrol tank is still full.


We sell inserts for gas-phase filters in classic or polyester design (better filtration properties).

We also have in stock gas-phase filters of foreign systems (Lovato, Tartarini, BRC, etc.)

The filter inserts must be replaced every 10,000 km, otherwise, the injectors may be damaged and the warranty may be voided.

For more info call 595 700 570.

Order a filter change at 595 700 570 or by e-mail or via the inquiry form and make an appointment.

Replacing the filters itself is a matter of about 15 minutes.


Currently, our products do not have the R115 homologation, which is required in some EU countries.

You need to have a revision protocol; if you don't, you need to do a revision with the listing and you will get a new one.

You take the revision protocol (or also the attachment to the technical certificate) + the large TC. With that, you will go to the municipal office with the extension. scope and you want an application for LPG registration. Based on this, they will write LPG as an alternative drive to a large TC.

A new little TC will exhibit for you for 50 CZK. Then all that's left is a transcript.

From 6.9. 2011, vehicles with alternative LPG / CNG propulsion can be legally parked in any underground, above-ground or covered garage. However, provided that the garage is not marked with a traffic sign prohibiting entry to LPG / CNG vehicles. However, the places marked in this way have decreased rapidly since 2011.

Tanks and multivalves

If it is a brand that we assemble (GZWM, STAKO), we are able to deliver a new passport through the manufacturer. We are not able to advise on other brands.


We offer LPG installations in almost all passenger cars, regardless of manufacturer or brand.

However, some direct fuel injection engines are an exception, such as Mercedes with CGI (Charged Gasoline Injection) and BMW with HPI (High Pressure Injection). Currently, direct fuel injection engines are problematic for LPG installations.

For some new Renault, the VIN code is in the trunk under the spare wheel. If the owner of the vehicle wants to install gas or replace the tank, it is necessary to go to another place for a replacement VIN code.

The procedure is as follows:

  1. Go to the municipality with extended powers and apply for a VIN COUNTING AUTHORIZATION IN SPARE TECHNOLOGY.
  2. Ask immediately how the new VIN will be checked (each official wants it differently).
  3. With permission to go to a specialized company that is authorized to perform this activity
  4. Go to the station of techn. inspection with the new VIN (or continue according to the agreement at the municipality).

We recommend CARSCH AUTO in Ostrava and its surroundings.

The risk of an LPG tank explosion is significantly lower than in the case of a tank with conventional fuel (petrol, diesel). Even in extreme fire situations, safety tank systems should protect the car from explosions against rapid pressure build-up.

Vehicles usually start burning from spilt fuel. LPG gas explosions occur only rarely and mostly due to leaks in the system and only apply to vehicles that are parked in enclosed spaces, ie garages or underground car parks.

If you have parked in a closed garage or underground (which is sometimes forbidden but commonly violated), and you feel gas next to your car, try to manually push the car out without turning on the engine. When you are out, try to start the car and go to the service station.

Consumption is approximately 5-10% higher than petrol. This is true provided that the vehicle is in good technical condition, the measured gasoline consumption can of course be compared with the measured gas consumption. If the customer wishes, we are able to measure the difference in LPG / petrol performance.

Every filling station with a reputable LPG supplier always switches to a winter LPG mixture in the winter, as is customary, for example, with diesel. In this case, the user of such a drive makes no difference.

The ever-tightening rules and regulations for LPG components ensure their complete safety. As an example, we can mention the tank of vehicles, where the LPG tank is made of steel and, unlike gasoline tanks, undergoes very demanding destructive tests. The customer is also informed of periodic inspections (once a year) to ensure the safe operation of the vehicle.

Currently, the discount cannot be applied to multi-valves, maintenance instructions and filling points.

To register the LPG installation in the technical certificate at the office, an invoice is required for converting the vehicle to gas (the invoice should include the VIN number of the car or its license plate) and a certificate of homologation for the installation of the gas installation. Therefore, it is necessary to contact the companies that issued these documents. Without this information, it is difficult to proceed. In the event that the company of the issuer of the document no longer exists, we will contact the owner of the homologation, who will issue a duplicate homologation. In case we do not know where the car was converted to gas, we should find out what products we have installed and find a representative of these companies in the immediate vicinity.

We recommend changing the engine oil at the intervals specified by the vehicle manufacturer. Although LPG oil looks like new for a long time, it probably doesn't contain carbon, but it can be contaminated with various other chemicals that can significantly reduce the lubricity of engine oil. These are mainly sulfur and heavy hydrocarbons, the content of which is still subject to CTIA inspections at LPG filling stations throughout the Czech Republic.
