LPG represents a major improvement over conventional automotive fuel sources. It is also
more eco-friendly and is therefore cheaper in the commercial context than conventional
sources of car gasoline.
The conversion process
Diesel engines do not have spark ignition as diesel is a self igniting type fuel. However
Petrol and LPG needs ignition so they need a spark plug to provide the initial ignition to
run the combustion. As such converting a diesel engine into LPG compatible makes the
car incapable to run any further using diesel. Unlike in petrol engines which can be retro
fitted and made a virtual duel fuel system, converted diesel fuel cars are only mono fuel
The simplest way to do this conversion is to remove the cylinder head where the diesel
injectors were mounted and bore the holes of the machine spark plug into that spot. If there
is ample room for this, this operation is possible if the spark plug does not have to be
positioned anywhere. It is possible to either plug the initial diesel injector holes or use
them as LPG injectors.
Fuel efficiency, savings and changes after conversion
Test findings have not shown a single instance where the diesel / LPG mix has decreased
diesel consumption by more than 25 percent in converted vehicles.
None of the LPG / Diesel mix systems tested resulted in a more than 25 percent reduction
in diesel consumption. Some of the other benefits are as such, apart from the cost savings
as mentioned above. After the transformation of the fuel system into LPG, the diesel
engine becomes much quieter.In a diesel engine, there is a classic knock that is
significantly reduced following the conversion.
The ride becomes a lot smoother as the LPG elements begin their combustion before the
diesel fuel does. The engine also achieves the optimal temperature faster and greatly
decreases emissions of carbon dioxide, sulphur dioxide, metallic contaminants, etc. As
LPG is a hydrocarbon fuel, it is readily available because it is a by-product of the
manufacturing process of oil and natural gas.It effectively burns more efficiently and exits
the internal combustion chamber in a much purer form, containing much less sulphur and
