Road Run testing was done on Santro car which had an EFI
engine. The fuel tank of car was used in fuel supply to
engine. According to HDIP, the testing database needs to
be enhanced in a further controlled environment for deeper
analysis. Thus testing was repeated together by HDIP and
Clean Power Pvt Ltd on carburettor operated car with alteration
in fuel supply. The alteration in fuel supply was to cater
the un-used quantity of fuel in the tank after each test. |
In
this testing, representatives of HDIP (a Senor Scientific
Officer and a staff member) personally participated and
had observations with highly calibrated laboratory equipment
in order to get accurate results. |
Based
on the experience with ethanol, optional use of ethanol
as transport fuel is recommended. A pilot filling station
of ethanol (E5 & E10), with blending at the point of
sale, shall help to practically evaluate supply chain, logistic
and dispensing issues. This will enhance the database of
ethanol usage and also clarify commercial, economic and
cultural issues. |

| FINDINGS |
|
There
was no problem of starting the engine. Every time, engine
started instantaneously. Average self duration was less
than 01 second. |
| |
There
was no sign of knocking and missing. |
|
The
engine temperature gauge remained at the same level as for
petrol. This means, if there were any temperature variations,
they were off-set by the temperature thermostat. |
| 
|
The
acceleration of car was same for petrol, E5 and E10. The
acceleration was very slightly less for E20 at speed of
100 kph and above. The reduced acceleration was definitely
insignificant as compared to acceleration loss with use
of CNG. |
|
The
fuel efficiency varied under different conditions and with
different blends. |
|
No
problem was faced during handling, storage, transportation
and blending of ethanol during these tests. |
