Why LPG / CNG

At a time when petrol and diesel price attacking forty crowns, the interest of motorists turning to gas. Does it make sense steps to conserve?

Imaginary scissors between the prices of petrol and diesel against gaseous fuels widened so that today the conversion to gas is also considering its obdurate opponents. No wonder the new Octavia gas against gasoline pay for themselves after covering thirty-four thousand kilometers. For the average motorist, this means two years of operation, service chauffeur to handle even for a quarter. Gas why he was attracted to.

LPG

Advantages of LPG

• The biggest advantage is cost savings for fuel (up to 50% saving)
• Higher engine life
• Increasing the overall finish
• Environmental Investigations
• A dense network of petrol stations in both the Czech Republic and Europe

Disadvantages of LPG

• The initial investment in rebuilding (the opportunity to resolve installment)
• In some cases, reduction of the luggage compartment for the tank
• Inability underground parking

CNG

Advantages of CNG

• Save on Fuel
• Eco-driving
• Quieter car
• Safe operation
• The possibility of the use of domestic filling stations

Disadvantages of CNG

• The low number of filling vacancies in the CR (rising)
• High initial investment in rebuilding
• Reducing the luggage compartment
• Smaller driving distance to CNG

LPG or CNG?

 
       So why gas? Just a simple equation to calculate that if you run a lot, he quickly pays for itself. But it is good to twice than enthusiastic about it.
      Who wants natural gas, whether looking after the original installation of the vehicle manufacturer and rebuilding forget. This is because in this case much more complicated, larger tanks are needed and later adaptation is simply not worth it. But has this drive more about the future, although for natural gas since the beginning of this year pays excise duty (but at least EUR gradual increase to tolerable 2.36 per cubic meter crown in 2020). "If you have tanked where natural gas is sold to auto factory good choice at a price comparable with diesel. At the same time run for the crown per kilometer, "says enthusiast and owner of multiple car on CNG Zdeněk Rezac. He admits, however, that the problem is a small supply of used cars as (when they drop the price to a reasonable limit), and thus they need to Germany or Austria. We strongly discourages retired taxis, whose users also liked this fuel.
       If we talk about the investigation, then it's more a case of LPG. Rebuilding it might otherwise be an ordinary car, treatment is not expensive and workshop offering installation of LPG can be found in almost every major city. It can take two to three days, unfortunately, is now due to greater interest waiting for several weeks. So who is seriously considering the gas should hurry. Workshops warn that although the components are not yet, but soon may not be.
       Neither the authorities should not be afraid. Thanks slůvkům "type mass rebuilding" is written in an official vehicle modifications to documents as easy as in the case of a towing devices. And if you are worried about losing the guarantee with a new car, it is possible only under the assumption that it would cause defects in direct connection with mounted gas. For entrepreneurs, however, applies when buying such guarantees which they agree. Here we recommend specifically to treat dealer.

What is the difference between LPG and CNG?

 
       LPG (liquid petroleum gas - liquid petroleum gas) is a by-product of the extraction and processing of oil. In tanks of vehicles is a liquid, is heavier than air, therefore, in case of leakage does not spontaneous ventilation. For this reason, it is forbidden entrance to the underground garage. Its combustion produced emissions significantly lower than gasoline or diesel.

Advantages

• large network of filling stations (about 800) and service / break
• less expensive remodeling (20-30 thousand. CZK according to engine type), suitable for petrol engines with a smaller annual proyezd km
• savings of about 40% compared to gasoline
• the possibility of placing the tank to reserve space without limitation trunk, while preserving the original tank

Disadvantages

• variable quality gas
• liter LPG consumption higher than gasoline
• economically based only on the transition from gasoline to LPG version, the transition from the operation of the diesel version to the LPG brings savings
• it is not possible to produce a renewable resource
   

      CNG / BioCNG (compressed natural gas - compressed natural gas or biomethane) is natural gas or biomethane (natural gas produced from renewable energy sources or waste) usually compressed to 200 bar min. In tanks of vehicles in gaseous form, is lighter than air, ie in the event of leakage occurs spontaneous ventilation. Its combustion produced emissions significantly lower than that of petrol or diesel and are also tens of percent lower than that of LPG.

Advantages

• consistent quality of gas equivalent octane number of 130 favorably influencing quiet engine
• savings of about 60% compared to gasoline, 40% diesel
• Offer original modified CNG vehicles without occupation of trunk
• The possibility of a truck and bus transport on CNG with a significant economic effect using a modified factory CNG versions
• the possibility of producing BioCNG from waste (sewage, garbage, sewage) and renewable sources (corn, grass)

Disadvantages

• smaller network of petrol stations (45 in 2012), it is possible to eliminate in-house services (ask us about the possibility of renting a filling device)
• expensive remodeling of about 40 thousand. CZK because of pressure bottles with the annexation of the boot
• infrequent service network
• higher cost of acquiring a factory modified CNG version (about 50 thousand. CZK for comparable performance)

It is worth to me?

         For whom, then gas? There are two groups. First gas car lovers who may not even enough to roll, to build gas responsibly, properly invest in revisions and casually little saving. And then others, who look only to the crown, still buys old ham, mainly to run on gas, and then often wonder that it must solve technical problems. Such damage good idea, and the other is rightly not love.
        We raise our hand for the first trip. At the same time strongly advised that if you want to save, you must not do so at all costs. All minor fuel does have one thing in common - without a certain amount of enthusiasm and occasional half-closed eyes (there are still negatives), it simply will not work. If you accept this, you can easily save money and still have the feel good about themselves.
        By the way, as well as economical diesel engine reliably destroy suspicious diesel, the same thing happens with extralevným gas. In short, you have to calculate if you just want to ride or take a little extra work and save it. We recommend, however, plumb blindly in search of savings and consider the pros and cons that you did not become a series of disappointed. Gas can not help it and eventually you about as they fled to diesel.
