Inductive Ignition
TLDI adopts an inductive ignition system that provides the fuel combustion at higher efficiency, lower fuel consumption and
lower emission.
The inductive ignition of TLDI has spark plug ignition duration that is longer than that of conventional two stroke carbureted
engines for surer combustion of the air-fuel mixture in the combustion chamber, ensuring more stabilized engine operation
under varied operating environment. The adoption of this ignition system allows to achieve smoother engine operation with
lower fluctuation of engine speeds during idling.
1. TPS (Throttle Position Sensor) Assembly
TPS consists of two sections, TPS1 and TPS2, that
function together to detect openings of intake valve
(throttle butterfly) and throttle (advancer arm) of the
throttle body, and transmits the signals to ECU.
Remove only as an assembly. Do not remove
the two-phillips head screws (with paint that
hold sensors together).
2. CPS (Crank Position Sensor)
CPS detects the crank shaft position and revolution speed
by detecting the encoders located on the ring gear of the
flywheel, and transmits the signals to ECU.
3. Water Temperature Sensor
The water temperature sensor detects the temperature of
cooling water that flows through interior of cylinder and air
compressor, and transmits the signals to ECU.
4. Oil Level Sensor
During operation of the engine, the oil level sensor
operates and informs of low engine oil level through the
oil lamp of tachometer and buzzer if the oil level is lower
than the limit.
