Engine - INGENIUM I4 2.0L Diesel (G1890692): Overview

The Ingenium I4 2.0L Diesel is an in-line four cylinder, turbocharged engine which employs advanced modular design principles. The Ingenium I4 2.0L Diesel four-cylinder engine has the following power and torque outputs: 180PS/430 Nm.

The engine features a split-cooling system; 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 maintains static coolant in the cylinder block while allowing 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.

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.

Variable Camshaft Timing (VCT) on the exhaust camshaft enables faster catalytic converter heating, minimizing harmful emissions during the critical warm-up phase. The VCT system is controlled by the Powertrain Control Module (PCM) using information from Camshaft Position (CMP) sensor. The engine uses a Bosch high pressure direct injection, common rail fuel system with fuel pressure provided by a high pressure fuel pump which is chain driven from the crankshaft. The high pressure fuel pump supplies the fuel rail at a pressure of 1800 bar (26106 lbf/in² ), the fuel rail then supplies the four fuel injectors with fuel at a controlled pressure. The high pressure fuel system provides low noise, high efficiency and excellent fuel mixture formation within the combustion chambers.

The engine incorporates a sophisticated Exhaust Gas Recirculation (EGR) system which further assists to ensure emissions are below the limits set by EU6 and LEV160 regulations. The engine meets EU6 emission regulations in Europe and Rest of World (ROW). EU6 and LEV160 compliance is achieved using Selective Catalyst Reduction (SCR).

The turbocharger design utilizes a high temperature cast iron exhaust manifold with a Mitsubishi Variable Geometry Turbocharger (VGT).

Ingenium I4 2.0L Diesel engines are characterized by the rapid build-up of torque from very low engine speeds, enabled by highly efficient Variable Geometry Turbocharger (VGT). Maximum torque is maintained over a wide engine speed range, ensuring instantaneous response and strong acceleration whenever the driver demands it.
