Biodiesel is an alternative fuel resource that can be prepared from the vegetable oil, animal fats and wasted cooking oils. The process of converting the oils to biodiesel is called as transesterification. Crops such as palm, soy bean, rapeseed etc are the biggest source for producing oil that is used for biofuel production.
Mostly waste vegetable oil is used for producing biodiesel. This vegetable oil is got from the restaurants, chip shops, food producing industries etc. But the oil that is got straight from the oil industry has a great potential it is not used commercially because the price of these raw oils are very expensive. And the product that is developed from this oil is also too expensive to compete with the diesel prepared with fossil materials.
This biodiesel can be used as an alternative to petroleum as it a renewable resource. Biodiesel produced from this oils cause less pollution than the petroleum. This can be used in combination with either petroleum oil or heating oil and also can be used alone. In combination of petroleum the common mix is 20/80 i.e. 20% of biodiesel and 80% of petroleum. Use of biodiesel in the engines requires only little or no modification.
Biodiesel is now been used as a diesel engine in number of agencies. The results are said to be comparable with petroleum in all the areas like power, efficiency, climbing, hauling etc.
Like other conventional diesels at very cold temperature biodiesel also will cloud and form gel. The recommendation for the vehicle that uses the biodiesel is the same as the others. Park them in the shelter, you can use fuel heater if necessary or can mix with #1 diesel.
In cold season it is should be handled carefully
Has vaguely few energy content then diesel fuel
Tries to weaken as non-synthetic or natural rubber in the parts of the fuel system
There might be higher level of nitrogen oxides emission depending on the state of engine tune.
Biodiesel is more 4 times eco-friendly than petroleum. And it is also non-toxic. It will not suddenly catch fire under normal conditions since it has a high flash point. The odor of this biodiesel is also mild and pleasant.
