The document discusses the i3s technology, an automatic start/stop system in vehicles that helps reduce fuel consumption and greenhouse gas emissions. It highlights the historical development of this technology, its advantages and disadvantages, and its growing adoption across various automobile segments. i3s technology is expected to play a significant role in achieving stricter carbon emission standards by 2020.

2. WASTING FUEL
Delhi wastes 40kL of fuel per day in traffic jams
6 billions gallons of gasoline wasting in USA per year
11 million tons of CO2 & 0.2 million tons of NOx and 5k tons of particulate
matter into air

3. IDLE START/STOP SYSTEM
• I3S technology is one of the best
technologies available in automobile industry.
• I3S is a green technology that automatically
shuts the
engine when idling and turns it on when
needed
• It can assure you to save fuel and reduce
green house gas (GHS)

4. HISTORY
• Devices of this type have been
developed by Toyota in 1964 tested
since mid 1970s.
• Fiat Regata “ES”, Volkswagen Lupo
“3L” and Audi A2 “3L” etc.
• Recently, Hero Motor Corp has
introduced I3S tech for two wheels in
India

5. ENGINE START/STOP
• I3S is a battery operated sensor circuit that detects the
idleness of the engine.
• When it detects the idleness of the engine, it turns off
the engine and when clutch/accelerator is pressed it
turns on again.
• You can switch on or off the I3S circuit with a switch
but optimum battery level is needed to operate this
function.

11. ADVANTAGES AND DISADVANTAGES
PRO’S
• Fuel consumption is reduced
by up to 5% – 10% in city
driving
• CO2 emissions are
reduced by up to 5% –10%
• The engine restarts with in
350 ms and in
complete silence.
CON’S
• Fuel saving is not as good as
Hybrid
• Some vehicle functions may
not run when engine
is off (Ex: AC)
• This technology require special
type of battery &
stator

12. • Used in Hero Splendor i -Smart bike
• BMW uses S/S Tech. across many of its cars & MINI line for
2008
• Bentley Bentayaga (2016) model
• General Motors used this Tech. as eAssist Technology
• Volkswagen began using S/S system with polo, Golf & Passat
(2007)
• M&M has introduced the S/S system based on Micro Hybrid
system to India
APPLICATION

13. • More than 50% of the newly registered vehicles will
have Start/Stop as standard technology after 2013
• Even though this technology is widely used in
small/mid segment cars, but it also has high potential
for compact and luxury car segments
• It is key technology to be used with other fuel saving
technologies to attain the stringent carbon norms of
2020
