Engine - INGENIUM I4 2.0L Petrol (G2313267): Overview

The Ingenium I4 2.0L petrol engine is an inline 4 cylinder, turbocharged engine that uses advanced modular design principles. The Ingenium I4 2.0L petrol engine has the following power outputs:

• 200 PS
• 250 PS
• 300 PS.

The engine features a split cooling system. The system contains a Powertrain Control Module (PCM) controlled electric thermostat and a fully variable coolant pump. The variable coolant pump enables engine coolant to remain static in the engine to maximize heat transfer during warm up. When engine coolant flow is required for engine cooling, the minimum flow is provided by the variable coolant pump.

The split cooling thermostat housing limits engine coolant flow in the cylinder block. The thermostat allows engine coolant to circulate through cross flow channels in the cylinder head. Parasitic losses are also optimized when the variable coolant pump is delivering reduced flow.

For additional information, refer to: ENGINE COOLING .

An electronically controlled variable flow oil pump with integral vacuum pump matches its flow rate according to engine speed, load and temperature. Oil flow to the piston cooling oil jets is solenoid controlled and operates only when needed.

The 2 camshafts incorporate the Variable Camshaft Timing (VCT) system. The VCT system allows the timing of the intake and exhaust valves to be adjusted independently of each other. The VCT system is controlled by the PCM using information from the Camshaft Position (CMP) sensors.

The Continuous Variable Valve Lift (CVVL) system adjusts the intake valve lift. The CVVL system allows the engine at operate at optimal efficiency. The CVVL system reduces fuel consumption and increases power and torque in the lower speed range. The CVVL system is controlled by the PCM.

The engine uses a Bosch High Pressure (HP) direct injection fuel system. The HP fuel is provided from a HP fuel pump driven by a cam on the exhaust camshaft. The HP fuel pump supplies HP fuel to the fuel rail, and the 4 fuel injectors at a controlled pressure.

There are many dynamic and static seals on the engine. All seals and gaskets on the engine are single use items and when removed, they are to be replaced.
