Fuel economy {{DESI STYLE}}

I do not understand one thing that why car and auto companies spend billions for inventing new technologies and produce complicated attachments like ECUs, CRDi systems et el just to make their cars and autos more fuel efficient.

Why all this hoola bloo in the name of technology when this could be achieved with atleast 80 years old technology.

Let us take for instance of a light transport vehicle, say a 2 tonner small truck. Going by the present market standards it should have atleast 4 cylinder diesel engine with minimum 3000 cc and if possible a turbo attachment. It will return anything between 10 to 12 kmpl or maximum upto 15kmpl.

Whereas, if we take into consideration about the actual performance of a low tech Lister or Petter engine having 6 to 8 hp configuration, it could easily run for an hour on just one litre of diesel on full load of 4" tubewell. ( Not an easy load, A four cylinder engine will consume 3 litres for the same job )

If we fit this Lister or Petter engine on any 2 tonner with reductions before the final transmission gear box, it could transform loads of torque into useful power to enable the LCV run atleast 40 to 50 kms in one hour with full load.

Yes, this is the point which I would like to stress that if this engine happens to consume one litre diesel in one hour and could run atleast 40 kms than it should come as a clear winner considering the fuel efficiency figure, low cost of the engine ( Rs. 10 to 15 Thousands per unit ) and easy spares availabilty throughout the continent.

Local Suburbs and rural market are not after the luxary of speed and comfort. It is after saving money while initial investment and on running costs.

All we need is to develop a very simple technology to fit these crude engines on rural transport vehicles ( RTVs) by removing all problems like heavy vibrations, and providing an auxillary gear system to have higher speeds and also providing a torque converter before the gear box etc.

Already there are working examples in the form of Petter rehras, Jugaroos assembled by local mechanics with jeep chassis and gear box attaching a Petter engine capable of hauling around 1500 bricks in a single trip. ( Half of what a 110 hp truck can load )

We need such vehicles for the rural and suburban masses

Any idea or suggestion ?
