Liquefied petroleum gas (LPG) is mostly propane when used for automotive purposes. It is produced as a by-product of natural gas processing or oil refining, and is often used as a bottled gas for cooking and heating. LPG is mainly used in cars and light vans. This means they have separate tanks for the LPG and petrol, and can operate on either fuel simply by flicking a switch. Running solely on LPG will however provide the greatest environmental and financial benefits although a small amount of petrol will be needed as most LPG vehicles start up on petrol and then switch over to LPG after a few seconds.
LPG will not burn LPG has a higher ignition temperature (4500 C) than automotive diesel oil [(ADO) 3800 C] and gasoline (3000 C) but not as high as Natural Gas for Vehicles [(NGV) 7000 C). A much hotter source is therefore, required for ignition of both LPG and NGV when used as automotive fuel.
  • LPG is stored as a liquid in its fuel container and develops an inherent vapour pressure which forces the liquid fuel to flow to a simple but effective fuel system.
  • If the fuel-air ratio is outside its flammability range of 1.8% to 9.6%.
  • NOTE : As a comparison the flammability range of acetylene is approximately 2.5%-8%. It is a gaseous fuel commonly used extensively in workshops and industrial sites - without mishaps - and yet it is potentially many times more hazardous than LPG.
  • LPG has a distinctive odour (ethyl mercaptan) added to it. This enables leak detection at very low concentrations of down to 1/5 of the lower limit of flammability.
  • In the case of leakage, LPG vapour, which is denser than air, mixes quickly with air to produce flammable vapours which collect in hollows or depressions in the vicinity of the leak. The presence of an LPG leak can be detected by the distinctive odour added to it.
  • Whenever LPG odour can be smelt it is extremely important to turn off the services valve and remove or eliminate all ignition sources.
  • Warning : Do not activate any ignition source by attending to start the engine or by turning any switch "ON” or "OFF". (Ignition, door and boot switches can be sources of ignition).
  • If the vehicle is indoors push or tow it to an open area away from opening in building and ignition sources then permit any leaking or residual gas vapour to disperse. (LPG vapour can also be dispersed with high pressure water diffuse spray).
  • Any vehicle which has an LPG leak or a suspected LPG leak should be inspected by an accredited or licensed LPG installer who will be able to test and repair the faulty system to restore it to a leak free condition.
  • Ignition sources are many and varied. Some common sources are matches, cigarette lighter, welding, grinding and operation of electrical switches. Too often-overlooked ignition sources static electricity and pilot flame on domestic hot water systems. Become familiar with sources of ignition in your workshop of garage.
  • We provide the latest kits from LOVATO, Italy who provide fourth generation LPG / CNG equipments which provide high performance and quality, low consumption with easy installations. The brand marketed by us is the best and world leader with ISO-9001, ISO:15500 standards or ECE-67-R approvals and are being exporting to many countries in Europe, America & Asia.
    A Vaporizer has functions dropping a LP gas pressure from a high pressure to a low pressure, vaporizing a liquid state LP gas which is stored as the state in the gas storage container, and controlling a leaving gas pressure. Vaporizer has two chambers which are called the primary and secondary chambers. When LP gas flows through the primary and secondary chambers, which drops its pressure from the fuel container pressure to an atmospheric pressure. At the secondary chamber the pressure reaches to an atmospheric pressure. Then the LP gas is mixed with air according to a vacuum pressure level of a Mixer
    This LPG vapour filter is fitted between the reducer/vaporizer and the gas injector rail on an Sequential Injection Systems. Carburetor or Single point injection systems doesn't require a filter. Filter should be changed about every 12,000 miles.
    This filter has 10mm ends and is also suitable for Zavoli, Bigas, Romano etc. most sequential injection systems on the market today.

    There are basically two models. One model is for cars with carburetors. This switch has a pulse sensing mechanism, which cut off the supply of LPG in case engine stops.It also cut off the supply within 2 seconds in case the engine stalls or fail to start. Another Model is for MPFI Cars. This is a Micro Processor based switch for MPFI cars. Here the car start on petrol & change over to gas automatically when the engine r. p. m. increases that is when the acceleration is given. This has auto chock & level indicators. The Electronic/Electrical circuit is developed by the company that as confidential trade practice keeping in view the safety of the user as upmost consideration.
    A gas cylinder or tank is a pressure vessel used to store gases at high pressure. There is also an provision for a safety solenoid which acts as a pressure relief valve and cuts the supply of gas in case of leakage and impact/accident. Besides the LPG tanks are made of strong steel and tested for explosion with three times the working pressure. Tanks are never filled with more than 80% capacity and have a Multivalve which is covered by a vacuum tight box releasing all vapors/LPG in case of leakage to outside of the car.
    The multifunction Valves have the features such as for Excess Flow Control, Manual Service Valve, LPG Level Gauge, 80% fill limiter and Pressure Relief Valve.
    The multivalve is connected to the switch via a electronic sensor showing the level of LPG in the tank. Tanks and Multivalves are approved by the Government of India, Explosives Department for safety

    This is a Mechanical device which functions on the principal of venture. This ensure Air-fuel mixing in the correct proportions. Thus this device is installed for introducing gaseous fuel to the induction air of the engine. The venture and other dimensions/design of the mix are so developed that different Models of Gas-Air Mixers are suitable for function on different cars.
    During gas operation, this device cuts off the flow of petrol on cars equipped with electronic injection and emulate the signal of the injections of other sensors. This device comes in different models and the right emulator model for car varies depending on the type of injection system.

    The LPG Solenoid Valve cuts off the flow of LPG during the period the vehicle is working on petrol and it allows LPG to pass when the vehicle is switched ON to LPG. lt incorporates an interchangeable filter and a magnet for keeping off from supply line any impurities that may be present in LPG. The filter is so designed and fitted in side the valve body so that it is capable of removing all particulate matter from the fuel that could cause malfunction of Shut off Valve or Vaporizer/ Pressure Regulator.
