ENGINE CONTROL SYSTEM [SKYACTIV-G 2.0]

id0140f4139900

Outline

• L-jetronic^*1 and D-jetronic^*2 type detectors have been combined for intake air amount detection, improving the accuracy of the intake air amount measurement.

― MAF sensor adopted

― MAP sensor adopted

― IAT sensor No.1 and No.2 adopted

• Valve timing control has been adopted on both sides of the intake and exhaust, improving fuel economy and emission performance.

Intake side: Electric variable valve timing control

― Intake CMP sensor adopted

― Electric variable valve timing motor/driver adopted

― Electric variable valve timing relay adopted

Exhaust side: Hydraulic variable valve timing control

― Exhaust CMP sensor adopted

• Engine oil control has been adopted reducing engine load.

― Engine oil solenoid valve adopted

• DC-DC converter control has been adopted for improved power supply stability.

― DC-DC converter adopted

• With the adoption of fuel pump control, fuel pump power consumption has been reduced, improving fuel economy.

― Fuel pump control module adopted

• Generator output control adopted, fuel economy/idling stability improved.

― Current sensor adopted

• With the adoption of the ion sensor, which detects pre-ignition, engine reliability has been improved.

• LIN communication has been adopted to the current sensor and DC-DC converter for simplified wiring harnesses.

*1 :Measures the intake air amount directly using the MAF sensor.

*2 :Measures the intake air pressure introduced into the cylinder using the MAP sensor and calculates the intake air amount indirectly.
