The wait may be over sooner than expected for those of us waiting for the Nano diesel. Bs motoring has snapped the Nano diesel being tested on the Mumbai – Pune expressway. As noticed, the rear end seems heavier (as the car has a lower ride height) and the rear underside seems different from the petrol Nano we have seen, making it obvious that Tata Motors has already started testing the diesel engine on the Nano.
The Nano diesel is to be powered by a common rail diesel engine (developed by Bosch) and is expected to be a single cylinder, about 600 – 700 cc engine producing about 30 – 35 bhp and considerably higher torque than the petrol version. It may not be out of place to mention that Ratan Tata had lately commented that the Nano Diesel will be made available “sooner than expected”. Its likely that the diesel version could hit the showrooms before the end of this year.

Wont there be more noise and vibration if its a single cylinder engine. Need to wait and watch.
The engine is going to be a good one if its from Bosch. However I wonder how a single cylinder engine can still have a common rail.

engine developed by bosch?? Tata must have had enough of their cars going up in flames due to their own engines…

That is a very ignorant statement to make. Moreover i do not believe it’ll be a single cylinder. The NVH will be a major constraint. NVH is a customer touch point and will not be sacrificed if the product is to do well. Bosch doesn’t develop engines, the engine block would not be developed by them.

CR in single cylinder!
To my knowledge, CR just maintains the high fuel pressure in its reservoir and helps in attaining max combustion efficiency (CI in this regard).
CR also helps reducing vibrations and emissions. Yes, vibration. High bar (pressure) of fuel helps reduce vibrations. CR will answer your question about noise and vibration.

Hello Mr.Madhav, how does common come into picture when there is only one cylinder.
Common makes sense only when there are more than one cylinders sharing a common rail.

twin cylinder it will be !. Could be a sell out.
