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. In India the supply is as per BIS : 14861
Perceived advantages :-
1) Kit costs as low as Rs.6000/- to Rs.7000/- (CNG kits cost upwards of Rs.30,000/-)
2) Cost per kilometer of running approx. 80 paise (petrol being nearly Rs.2 per km)
3) Household subsidised cooking gas cylinders available easily.
4) Dealers available dime a dozen in every locality who proclaim their ongoing illegal business of fitting LPG kits in vehicles as legal.

Advantages over other fuels
The combustion of Autogas is smoother as a result of the higher octane content. Unlike other fuels, no additives are required to guarantee high quality.
• Autogas contains no lead and is therefore cleaner and leaves no residue.
• It is actually better than petrol because it reaches the engine in pure gas form with improved combustion resulting and fewer knocking.
• With modern technology, there is hardly any discharge of carbon monoxide, and compared to petrol and diesel, the exhaust fumes contain less harmful substances.
• The life of the engine is extended as a result of the absence of acids and carbon deposits. One can safely state that engines on LPG last almost twice than that on Petrol/Gasoline.
• Less carbon means less fouling of spark plugs and points i.e less wear and tear.
• The engine oil does not become diluted with a consequential reduction in servicing costs.
• Unlike diesel, you do not have to adjust your driving style. Cold starting is no problem, engine performance is almost exactly the same as with petrol. There is no spilling when filling your tank and no possibility of theft or pilfering. Engine noise is low and you\'ll be driving in a more environment-friendly way.
• The environmental advantages of Autogas for automotive use are indisputable.

Q. 1. What exactly is LPG and where does it come from?
Ans. 40% of LPG comes from the refining of crude oil and 60% straight from field production. At atmospheric pressure it is a vapour, under modest pressure it becomes liquid.

Q. 2. Most of my fleet is diesel powered?
Ans. This is not uncommon, so make the switch when your vehicles come up for replacement. Let us carry out a cost saving analysis now so you can see the benefits of changing your fleet to run on Calor Autogas.

Q. 3. What is going to happen to the price of Autogas in the future?
Ans. The cost of Autogas currently stands at around 45p per litre. Thanks to its environmental benefits, LPG has found favour with the government. In 2006 the Chancellor agreed to continue to give notice 3 years in advance of any changes in fuel duty. As a result, the price of Autogas at the pumps will continue to be around half that of petrol and diesel for the foreseeable future.

With care for the environment becoming a higher day-to-day priority, schemes are also being put in place which see taxation, insurance and parking incentivised towards LPG vehicles.

Q. 4. How is the infrastructure developing?
Ans. Currently there are more than 1,200 LPG refuelling stations in the UK, and this number is constantly increasing - however depot based fleets can take advantage of LPG immediately by installing their own tank on-site.

Q. 5. What about the cost?
Ans. Autogas retails at around half the price per litre of unleaded petrol and diesel. In practice this means that an Autogas vehicle is about 40% cheaper to run than a conventional fuelled equivalent, so depending on your mileage, the payback period of the Autogas conversion (currently around £1600) could be less than 2 years.

Q. 6. What happens if an Autogas vehicle is involved in an accident?
Ans. All LPG tanks are rigorously tested and all are considerably stronger than conventional fuel tanks. The UK has stringent safety standards for Autogas vehicles and by selecting a reputable equipment manufacturer and/or converter approved by the LPGA you are assured peace of mind.

Q. 7. How much cleaner is Autogas than petrol?
Ans. Carbon dioxide is widely regarded as a main contributor to the greenhouse effect, which is making our planet warmer. Autogas reduces CO2 emissions from vehicles previously powered by petrol by 15%. Autogas also emits 97% less Benzene than unleaded petrol.

Q. 8. How much cleaner is Autogas than diesel?
Ans. The black smoke that we see coming from diesel vehicles cause over 20,000 premature deaths a year. By replacing a diesel engine with an Autogas equivalent, over 90% less of this particulate matter would be emitted.

Q. 9. If I convert my vehicles to Calor Autogas, can I still drive on petrol?
Ans. Yes, and with bi-fuel you\'ll almost double your range. The petrol tank still remains in the car and the driver can switch from gas to petrol, or vice-versa.

Q. 10. Can LPG damage my engine?
Ans. No. In fact, LPG is a cleaner burning fuel engine, so life is extended and less maintenance is required.

Q. 11. Will converting affect the performance?
Ans. There is very little difference in performance - however, with a liquid injection system, performance can be increased by 5%. Some drivers find increased drivability and for anyone used to driving on diesel, there\'s obviously a significant reduction in noise.

Q. 12. What about the vehicle warranty?
Ans. All OEM bi-fuel vehicles carry full manufacturer\'s warranty. Most retrofit conversion specialists will cover the LPG systems; however this needs to be checked.

Q. 13. How much space does the tank take up?
Ans. For a range of about 300 miles most tanks take up less space than a spare wheel.

This is Highly durabel LPG Gas Kit Cylinder that stores Liquid Petrolium Gas at high pressure. It is generally place at the back of the automobile near cabinet.

These pipes are made of copper and used in LPG Kit t connect the cylinder and Kit

This is the place where Liquid Petrolium Gas Mix with air in accurate proportion so that to burn properly into the engine.

This switch is used in changing the types of fuel allow to pass into the engine of LPG Gas kit fitted automobiles.

Power Valve is the device into the LPG Kit that give spark to burn the fuel into the Engine

This the cylidrical portal of power valve

This is the valve that allows to flow petrol into the engine

Gas Tight Box is the device through which gas flow is mentained.

Injector Emulator inject LPG gas into the engine

This pipe allows the flow of gas into the engine

Water Petrol Pipe allows petrol fuel to enter into the Engine

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. Two 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.
