ENGINE [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]
SM2565214
id0100000002u0
Special Features
• For SKYACTIV-G 2.0 and SKYACTIV-G 2.5 (without cylinder deactivation), the following have been adopted to lower fuel consumption.
-
― Mechanical resistance loss improvement from:
-
• 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 adopted.
― Pumping loss improvement from:-
• Variable valve timing mechanism adopted on both sides of intake and exhaust.
-
• Cooling loss improvement
-
― Coolant control valve adopted― Optimized engine coolant passage
• 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
• 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.
*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.
