3. INTODUCTION
•KARIZMA – 2003 > KARIZMA R-2007 >ZMR- 2009>
ZMR (EBR)- 2014
•PGM-Fi
•ECU monitored (16 Bit)
•Genes from HONDA CRF230L

4. SENSORS IN ZMR
•Throttle Angle Sensors (TAS)
• Air Intake Temperature Sensors
• Mass Air Flow Sensors (MAF)
• Oil Temperature Sensors (OTS)
• Oxygen Sensors
• Crank Angle sensors
• Bank Angle Sensors (BAS)
• Speed Sensors

5. THROTTLE ANGLE SENSOR (TPS)
Throttle is a valve mechanism allowing
to modify the amount of gas flow into
the cylinders of a gasoline internal
combustion engine.
TPS
POTENTIOMETRIC MAGNETIC INDUCTIVE

6. INTAKE AIR TEMPERATURE
SENSOR
• Monitors the temperature of the air entering
the engine.
• PARAMETER- Air Density & A/F mixture
• Similar to THERMISTER

7. MASS AIR FLOW SENSOR
• To determine the mass flow rate of air entering a fuel-
injected internal combustion engine.
1
• I = constant
2
• When bike moves, air contacts with wire
• Temperature of wire decrease
3
• Resistance (R) decreases
• Thereby More Current (I) & Voltage (V)
4
• As more I increases, more Temperature too increases
5
• At some point it attains equilibrium

8. MAF SENSOR
PLATINUM WIRE

9. OIL TEMPERATURE SENSOR
• Monitors the temperature of the engine oil
in vehicle & displays this measurement to
the vehicle’s occupants
• Its a thermistor that varies in resistance as
engine oil temperature changes
OXYGEN SENSOR

10. OXYGEN SENSOR
• Oxygen sensor sends measurements of the
amount of oxygen flowing into the intake or
exhaust system to the ECU.
• Generally monitor exhaust gas.

11. Oxygen Sensor
• Operates by measuring the difference in
oxygen between exhaust gas and external air, &
generates a voltage or changes its resistance
depending on the difference between the two

12. CRANK ANGLE SENSOR
Monitor ing The Position/ Rotational Speed Of Crankshaft.
•The Inductive
Sensor
•Hall Effect
Sensor
•Magneto
Resistive Sensor
•Optical Sensor

13. CAS
Inductive Sensors have the simplest construction and are
usually purely passive devices.
Hall Effect & Magneto Resistive Sensors have the
advantage over inductive sensors in that they can detect
static (non-changing) magnetic fields.
Optical Sensors do not
have great resistance
against fouling, but are
able to provide the
most precise edge
detection

14. SPEED SENSOR (RPM)
• Type of Tachometer
• Wheel speed sensor was initially used to replace
the mechanical linkage from the road wheels to
the speedometer, eliminating cable breakage
and simplifying the gauge construction

15. BANK ANGLE SENSOR
• Safety Device.
• Detects if a motorbike is leaning on an extreme
angle or if the bike has been dropped &
subsequently cuts power to the engine.
• To minimize the risks of a motorcyclist being
dragged back into the motorbike by a fast
spinning wheel when the bike is dropped at
speed.

16. BAS

17. CONCLUSION
• Sensors must harmony together with ECU.
• Continuous feedback system.
• Best delivery power even at Lean or Rich.
• Auto diagnostic characteristic.
• Pinnacle as “ ABOVE ALL”
