What is Biodiesel? || Features || Advantages || Disadvantages || knowledgeaboutautomobile.com

Biodiesel:

        



Introduction:

Biodiesel is a form of diesel fuel manufactured from vegetable oils, animal fats or recycled restaurant oils.



Features of biodiesel:

It is safe and biodegradable and produces fewer air pollutants than petroleum-based diesel. It can be used in its pure form (B100) or blended with petroleum diesel.

Common blends include B2 (2% biodiesel), B5 and B20. B2 and B5 can be used safely in most diesel engines.

However, most vehicle manufacturers do not recommend using blends greater than B5, and engine damage caused by higher blends is not covered by some manufacturer warranties.



 Advantages:

  •  can be used in most diesel engines, especially newer ones
  •  produces fewer air pollutants (other than NO x ) and greenhouse gases
  •  biodegradable
  •  non-toxic
  •  safer to handle.

Disadvantages:

  • use of blends above B5 may not yet be approved by manufacturers
  • lower fuel economy and power (10% lower for B100, 2% for B20)
  • more NO x emissions
  • B100 generally not suitable for use in low temperatures
  • concerns about B100’s impact on engine durability.

What is the MAGNETO IGNITION SYSTEM? | WORKING | knowledgeaboutautomobile957

MAGNETO IGNITION SYSTEM Magneto is a special type of ignition system with its own electric generator to provide the necessary energy for the system. It is mounted on the engine and replaces all the components of the coil ignition system except the spark plug. A magneto when rotated by the engine is capable of producing a very high voltage and it does not need a battery as a source of external energy. The high tension magneto incorporates the windings to generate the primary voltage as well as to step up the voltage and thus does not require a separate coil to boost up the voltage required to operate the spark plug. Magneto can be either rotating armature type or rotating magnet type. In the first type, the armature consisting of the primary and secondary windings all rotate between the poles of a stationary magnet. whilst, in the second type the magnet revolves and the windings are kept stationary. A third type of magnet to called the polar inductor type is also in use. In the polar in...
