Well, if petrol, octane and diesel come from the same mineral, then why is it possible to ride a bike with petrol, octane but not with diesel?
Many engines are running again. Well I want to run, maybe?
No, it’s not possible, come and see why
In simple words petrol is used in bikes to generate enough power to run the engine. In a petrol engine a spark from the spark plug ignites the petrol which moves the piston up and due to the crankshaft it comes down and this process continues and the bike is propelled.
It is also used to clean some bike components due to the viscosity of petrol and some other factors.
LPG or CNG cannot be used as substitutes, as their combustion rate is higher than petrol and hence there is a chance of fuel tank explosion.
And cannot be used in diesel bikes, because it is not possible to get the same energy as petrol by burning diesel. Because diesel combustion requires a large amount of fuel to be compressed and combusted, it requires a large cylinder which would not be suitable for a bike.
Although diesel engines have been used in other motorbikes including the Royal Enfield, motorbikes are not suitable vehicles for using diesel engines.
Some more reasons
Size:
Diesel engines are much larger in volume than petrol engines of the same horse power, hence the size, weight and price of the motorbike increases proportionately.
Noise and Vibration:
Diesel engine being a high compression (24:1) engine, noise pollution and vibration are much higher than petrol engines.
Heat: Due to the above, the heat generated in the cylinder is very high. To make an aircooled engine, the cooling area has to be increased, so the volume becomes very large.
Engine Corrosion: Excessive heat, noise and vibration cause engine parts to corrode quickly.
For the above reasons, petrol engines are preferred in motorbikes.
