ENGINE CONTROL SYSTEM [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]

id0140u0139900

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 variable control has been adopted reducing engine load.

― Engine oil solenoid valve adopted

• The engine coolant control valve adjusts the engine coolant control valve opening angle and supplies engine coolant to the appropriate engine coolant passage according to the changes in the engine coolant temperature.

• Further engine warming has been promoted by blocking each water passage while the engine is cool.

― Coolant control valve adopted

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

― Fuel pump control module adopted

*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.
