  • cng technologies in each country

    id like everyone to tell us which technology is used in their country, and which is the cost for the conversion

    i am not so instructed in this area, but ill try to explain what we use in argentina:

    most conversions are of the negative pressure type, it means, gas is delivered in order to the ammount or air circulating through air intake.
    this conversion costs 900 us dollars, or 600 euro, and consists in a gas tank, a reducing valve, a delivery throttle valve (or commanded throttle valve), and a venturi mixer located in the air intake hose
    in engines with carburator this installation is very good, in electronic injection cars, emulators to induce the ecu to think everything is ok should be implemented

    nowadays its is possible to convert using possitive pressure equipment, commanded by the very own cars ecu at a cost of 2000 us dollars or 1500 euro, being impossible to install this kits in carburator type engines. it consists on a constant pressure reducing valve, followed by a manifold of electronically controlled valves, commanded by a gnv central, which takes control on those valves according to original cars ecu outputs

    regulations about emissions of gnv cars dont exist or dont apply, normally all tests are based upon the car running on gasoline

    Dear luiswainer,

    'Be careful what you wish for...' Here is a link to a discussion already on our website. It gives some insights into entering the U.S. market.

    I hope this help and if I can answer any additional questions feel free to respond.

    Best regards,

      Re: cng technologies in each country

      i am reading and am quite intrested on us regulations
      everything seems to make ppl understand that us govmt will make its best to improve oil consumption, or at least this is my perception

      i am not involved in equipment manufacturing, just like the system, and the big infrastructure in my country helps me to run in a cheap and more friendly fuel (and have places to refuel)

      i only could see similar things in italy and germany, where almost every gas station has its lpg valve also (couldnt see more than one or two cng stations)
      of course i was runing on 1.6 euro/liter benzine

        HI!!

        In India currently ventury based system is being used however testing on Sequential syatem is in process and trials are being done by CNG companies. The same would be applicable since April 2010.

        Cost of conversion here depends upon the size of tank you choose (Generally starts from US$ 480 and goes upto US$ 1000.00)

        CNG in India is priced city wise where as its cheapest in the capital (New Delhi) Priced approx US$ 0.36 Per Kg

          I just got back from a little vacation in Peru. I didn’t see the CE station, Bummer, but I did see a significant number of “compressed gas” vehicles. The ever present “moto taxi” seems to often run on some sort of CG, CNG or LPG, I wasn’t sure. I wasn’t really clear what they were and although the people that I asked were adamant that they were Natural Gas vehicles. It seemed that the safety regulations were a bit different in Peru compared to the US. Tanks on the converted vehicles often sat in the passenger compartment, strapped down but in plain view. When I asked about conversion, I was told that the cost was $300 to $600. I had to wonder if the answers I was receiving were meant to placate and not accurate.

            $300 to 400 for a CNG conversion is common in some asian countries without enforced regulations as well. So you got that right. But it's not safe, nor clean.

              How much does a CNG conversion (aftermarket) cost in the Netherlands?

                At least US$ 4,000. Could easily be US$ 10,000. Every part has to be certified. A complete file has to be submitted to the inspection even before they start looking at the vehicle. Aftermarket conversions are not very common. I always advise people to buy a new CNG vehicle: plenty of choice at the same price of a diesel vehicle.

                      Italy is the leading conversion market in the world.
                      We actually have around a million vehicle converted. Conversion is very easy but cost depends on the type of engine and the cost of the service that for hour of job can be around 50 Euro + taxes here.
                      So the conversion kit can't cost normally more then 900 euro ll together for a 4 cylinder (with tanks and certification) an 8 cylinder can cost three times that amount.
                      ctually after 20 years of progress the conversion market is slowing down in my country, cause the manufacturers are producing state of art brand new bifuel vehicle with full worldwide guarantee and efficiency that resemble the one of a normal gasoline vehicles.
                      The current Offer between commercial vehicles and private passenger cards can quantified in some 40 different kind of models and severl more engine types.

                        Hello,

                        In Iran you can go to the car manufacturer and make them to convert your car to CNG or dual fuel car.
                        It costs about 100$ in Iran

                            Negative pressure kits are still prevalent in Brazil due to their lower initial cost. For less than $2000 dollars a negative pressure CNG setup can be adapted into any soccer-mom van...
