Is manufacturing of Two Wheeler diesel engines feasible ?

This will boost the manufacturing of Two Wheelers running on diesel fuel.

Thanks & Regards,

According to Wikipedia, they exist and are manufactured worldwide. Take a look @ this article: https://en.m.wikipedia.org/wiki/Diesel_motorcycle

Remember, diesel fuel needs very high compression to fire, and that requires very heavy engines which is obviously bad for motorcycles.

Plus, diesel engines don't normally operate in the rev ranges that are best for motorcycling.

its not feasible because diesel engine has a compression ratio 24:1, which is higher than petrol engine compression ratio of 11:1. Diesel engine must be bigger and of heavy metal in order to handle this high compression ratio. That's why the diesel engine is heavier than petrol engine and not suitable for small vehicle like motorcycle.

Because Diesel engine works on high pressure, so wear and tear is high in diesel engines. To reduce this wear and tear oil change are frequently required at every 5,000 kilometer instead of 10,000 kilometer in the case of petrol engine. Diesel engine produces more torque but low rpm than petrol engine. So in bikes where we need high speed, it is not suitable.

Also, Diesel has high energy per gallon as compare with the petrol. When diesel burns, it produces a large amount of heat which can destroy walls of the cylinder and other parts of the engine. So to reduce this heat, we need a greater surface area and proper cooling system. In order to achieve this greater surface area, the engines are made slightly bigger.

Due to their higher maintenance than petrol engines it is not suitable for two-wheelers. Diesel engines use more materials and also have advanced fuel injection system which makes it expensive.

Due to these reasons diesel engines are not commonly used in two-wheelers, but two-wheelers manufactures like Royal Enfield introduced it's first diesel bike but due to these reasons & due to pollution laws the bike was not so popular. However new technologies have to be made to overcome these types of limitations.
These all reasons does not mean that diesel engine is not better than petrol engine, but these engines presently not used in small two-wheelers. Diesel engines have it's own advantages.

Do you feel with Technology advancements, the desired diesel engines can be manufactured and there could be a potential market in the future for two wheeler vehicles running on diesel fuel?
