Automotive enthusiasts who know a lot of LPG can be replaced when the gasoline engine runs like a motorcycle. The result will be more economical and environmentally friendly. However, the facts are still too few people who dared to apply it.

If you do not know the technique, LPG cylinder for motorcycle fuel could explode and harm others around him, "said Budi Soelaiman Sunarto, founder of the Business Multipurpose Cooperative (KSU) Agro Makmur, Karanganyar regency, Central Java.

Currently LPG in containers the size of three kilograms of small tube is very easy to find. But, still not so many people are familiar with gasoline to LPG conversion techniques to running motorcycle engine.

Budi since 1998 formed the company in the village of Agro Makmur Doplang, Karangpandan, Karanganyar District. He developed an environmentally friendly energy technology-based ethanol and bio-methane or biogas. Equipped also making its production facilities, such as biogas tool to convert waste consumption of dry organic waste into methane or facilities for the use of bio-ethanol with fuel-efficient stoves ethanol.

Since 2009 found LPG to fuel motorbikes. One kilogram of LPG has been tested is able to run the bike as far as 100 kilometers to 200 kilometers. Mileage as far as it will depend on passenger load and gradient to the road taken.

Membrane

LPG can not necessarily just flowed into the combustion chamber engine motorcycles. If done carelessly, sparks in the combustion chamber will creep toward the source of LPG, the LPG cylinder explodes.

Budi said the key lies in the membrane. Membrane made of metal tubes that hold stocks of LPG before entering the combustion chamber through the carburetor. Then the carburetor was modified. Not too complicated modify it, stay off pelampungnya function. Function buoy was replaced with the membrane.

"Only two things that must be done. Never try to drain directly into the combustion chamber of LPG through the carburetor. Sparks will spread everywhere, LPG cylinder will explode, "

Gas supply valve

To test the feasibility of the membrane, Budi assisted researchers from the Center for Radioactive Waste Technology National Nuclear Energy Agency (Batan) Suryadi. According Suryadi, replacing the working principle of membrane function by considering the flexibility of the material floats.

The membrane consists of an iron tube 8 inches in diameter with a length of about 4 centimeters. On the surface of the upper and lower layers of rubber tube is given membrane. In order not to leak, rubber surface

coated with a thin metal plate. Of the membrane tube was supplied to the carburetor, the gas delivery valve.

According Suryadi, in testing the feasibility of the membrane, resistance to pressure to reach the required minimum of 12 bar. This is to anticipate the strength that comes from the pressure of LPG LPG cylinder.

Membrane limits the ability to hold on to exceed 12 bar pressure on the LPG cylinder which is only 10 bars.

After the LPG flow to the carburetor into the combustion chamber, will drape over the air. Regarding the composition, generally on a motorcycle petrol to 1 for gasoline with a capacity of 13 to 15 air capacity.

According to Budi, unlike the case with compositions that are required on LPG with air. Its composition is proportional to the capacity of LPG and 1 in 5 to 18 air capacity.

Such details. To start up the engine or motor, it takes the composition of 1 to 5 for the LPG and air (1: 5). Furthermore, for stationary engines running with the composition 1: 8.

Towards acceleration composition engine up 1: 12 and a 1: 18 when running normally.

3 kilograms of LPG retail prices in the market Rp 14,000 to Rp 15,000 per tube. This price is equivalent to about 3.3 liters of gasoline (the price of Rp 4,500 per liter).

According Suryadi, the range of 1 kilogram of LPG mileage could be 100 to 200 kilometers. So, one kilogram LPG cylinder 3 can be used for distances ranging from 300 to 600 kilometers, whereas only 3.3 liters of gasoline to around 100 kilometers.

"LPG is made from butane and propane are still relatively expensive when compared to the methane can be produced through anaerobic combustion of dry organic waste," said Suryadi.

Methane, according to Suryadi, the future of transportation fuels. Only this time packing and distribution is still a constraint.
