kk_RTR

Diesel engines have a very high compression ratio n so the engines have to be very sturdy (Read:Bulky).
Moreover, people here complain abt the vibes in RTR. Imagine wat will they say if they ride a diesel engine...(those who have ridden the diesel bullet aka Taurus will know what im saying) for those who haven't, imagine a 2 wheeled Tractor
starting the bike takes a lot of efforts....even the guys weighing 70 odd kgs will find find it hard.. so forget abt the others..Starter motors will be a lot heavy (read: Costly)

now talkin abt the recent technology in the Diesel engines, they have not reduced the Compression Ratio so that the engines can be made light weigh (compared to Petrol Engines) the Modern Diesel engines are light weight but only compared to their predecesssors...they are still considerably heavy.
Cold Starting a Diesel Engine is really a pain in ..... even the modern Diesel Engines are not as impressive as compared to the contemporary Petrol Engines.
The Torquier single cylinder mill will never ever be a smooth running mill it will have to be a multi cylinder (say inline or flat) this again will increase the COST of the bike..
A heavier Engine will also need a Stiffer Chassis, so more weight...


So now would u like to use a CHOTA HAATHI (BABY ELEPHANT) that doesn't move fast and also gives u more tremors than what the most powerful Earthquake wud have ever given????????

naaaaaaaaaaa...

But there is a Positive side of this too...
the Fuel Efficiency will be Rocket High...yup u guys read it correctly...
the Diesel Bullet used to deliver approx 70kmpl

Instead of Diesel bikes, manufacturers are going towards LPG and CNG bikes. Bajaj and TVS might be coming up with such bikes in the near future.

You can’t, diesel is compression ignited so if you reduce comp the engine won’t run. And yes you are right, a single pod diesel will feel like a generator.

RE had a diesel bullet for sometime with a greaves engine on it (same mill that our kissan bhais use to pump water, also a very efficiecent generator set :P). The tagline for is a bit of a take on the Old hero Honda line of "Fill it, write the odo reading on a piece of paper, shut it and forget it" lol!

Pfff It was everything that I dont like in a motorcycle heavy sluggish slow sounded like well a water pump/DG set.

Diesel is a great fuel but to power ships:P ... but bikes nah!

remember reading about this in the march issue of overdrive so googled it and giving the first link:

EVA Track T-800CDI diesel motorcycle launched, equipped with fortwo engine from smart

Another interesting link that turned up in my search:

DieselBike.net - 5nd British Diesel Motorcycle Rally.

I don't think Enfield made those Diesel Bullets. If I remember correctly, they were called "SooraJ" made by a 3rd party using the Bullet Cycle parts and Greaves Diesel engines.

I have a Diesel bull for this very reason. The torque produced by 5 hp machine is more amazing than the power 16Nm @ 1800. Many times i just slip to top gear and leave it in idle. The bike pulls cleanly in idle. I do have many plans to swap the engine with a much better options for touring purpose. Imagine triple digits of touring all day long and average of more than 50 kmpl that too diesel advantage. Currently the market is limited to 3600rpm for High speed diesels. Only force mini four super has an engine capable of hitting 4300 revs which is pretty close to bullet engine speed so i dont need to alter the gear box. But the con is its a single with 14 hp and 28 Nm engine. Ace HT is a twin perhaps the only twin in the market but the engine is slightly bulky and the revs limit to 3200 revs.

dear bro at shubhanker,
sorry would put it in the poll soon . just missed it

ma friend prajwal!
great job regarding the link u have provided by you. i appreciate ur intrest

dear coplay,
if u good give its specs i'll be very much happier

dear joel,
that some good technical thinking, i was rather thinking of 300cc 15-30 hp coupled with a turbo

dear sarvajit,
sorry bro will add it in . missed it in a confusion

dear gasolinejunkie,
seems ur unaware of current market trends. r&d are developing at a thunderous rate in our country . diesel engines rules indian markets, hope u r not aware of that too.anything is possible with dedicated r&d .just check the link

main_en

also check this data

main_en

bajaj, tvs or yamaha are not people who started to sell bikes just from few months back , they r in this field for more than few decades. thay have a strong r&d team and they have the potent to do so . thier potent is totally destroyed only by the conventional customers who dont want any new technology or still not yet came out of an pre-independence era

thanks,
madengine

Converting old army bullets to run on diesel was a common mod till the late 90s. Even RE had a diesel model called the Taurus, with a factory fitted Greaves diesel engine. It made about 6.5 bhp, was a devil to kick start and wasn't quick or fast. It was reviewed by Dilip Bam on Auto India mag. As I recall, the vibrations were so bad that the tail lamp unit fell off after a certain time.

There was also at least one other manufacturer of Diesel bikes. The bike was called Sooraj. It was similar to the bullet in build, but had a square headlamp, and slightly different fuel tank and covers and stuff. It too used a similar pumpset engine. It was a composite of various old school Indian bikes, mainly the Rajdoot and the Bullet.

Maybe someone should introduce a common-rail single cylinder diesel bike. The bullets are heavily priced as it is, but a CRDI cruiser sounds intriguing lol. Of all the indian bike manufacturers, I think that Bajaj is most likely to introduce something like that now. Especially since they have experience with small capacity diesel engines and mating them to two-wheeler gearboxes - The RE diesel autorick.

Maybe a two-stroke diesel would be a good idea.
