id0100000002dd


Special Features

•  For SKYACTIV-G 2.0, the following is performed to lower fuel consumption.
―  Improvement of mechanical resistance loss
•  Narrowed down crankshaft journal
•  Optimized piston skirt shape
•  Lowered piston ring tension
•  Roller follower adopted
•  Reduction of valve spring load
•  Stabilization of timing chain behavior
•  Optimized engine coolant passage
•  Optimized water pump impeller shape
•  Lowered drive belt tension
•  Optimized oil passage
•  Optimized oil pump shape
•  Oil pump discharging pressure control has been adopted.
―  Improvement of pumping loss
•  Variable valve timing mechanism has been adopted on both sides of intake and exhaust.
•  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.
