FUEL INFOMATION AND BREAK

Like most fluids, diesel fuel become thinner as it becomes hotter, and this change in viscosity affects the amount of fuel that flows through the injector at any given time.so to ensure the correct quantity of fuel is delivered, the ECM receives a signal from a fuel temperature sensor mounted inside the injector pump. As fuel temperature rises, the sensor reduces its electrical resistance. The ECM checks this value regularly and adjusts the fulling to compensate
A similar sensor on the cylinder head reacts to changes in engine coolant temperature, which the ECM uses to adjust fuel timing and quantity. The ECM also adjusts fuelling according to engine load, which is calculates from signals indicating the amount of air drawn in, road speed, engine speed and throttle position.The ABS system supplies the ECM with the road speed signal, and driver demand is signaled electrically by a throttle position (TP) sensor linked mechanically to the accelerator pedal. The signal voltage is varied as the pedal moves, allowing the ECM to determine the necessary engine speed and the rate of acceleration or retardation, and thus increase or reduce fuelling, or shut the fuelling off during overrun.
the clutch pedal switch signal the ECM whenever the clutch pedal is pressed, allowing it to shout off the cruise control function. Whenever the break pad applied, the ECM receives two signals from the break pedal switch one to deactivate cruise control, and one the check in the circuit.
