Question

Advantage and disadvantage of LPG

Answer 1

Advantages of LPG:

It contains very less amount of carbon in it, hence LPG powered vehicles produce almost 50% less CO2 than petrol. However,nitrogen compounds are comparable to petrol.It mixes with air at all temperatures.It provides a uniform charge for combustion, in case of multi cylinder engine.It has very high compression ratios.It has very high antiknock characteristics.

Its calorific value is almost 80%, compared to that of gasoline.However, its very high octane number compensates the thermal efficiency.Researches proves that using it saves almost 50% of cost than petrol.The engine may have 50% longer life.

Disadvantages of LPG:

It produces 10% less power, compared to petrol,on the same engine.Its ignition temperature is higher than that of petrol,it leads to 5% less lifetime of valves.An efficient cooling system is required,since same is used to provide the heat to the LPG vaporizer (convert liquid into gas).Due to heavy cylinders, used to store LPG,weight of the engine gets increased considerably.A special fuel feed system is required for it.

Answer 2
