Jeep has announced that the heart of the 2019 Jeep Cherokee will be a 2.2-liter MultiJet 195ps engine. The 2.2-liter MultiJet II turbo diesel with stop/start tech will be paired with a 9-speed automatic transmission.
The architecture of the 2.2-liter engine includes a specific 16 valve twin camshaft aluminum head designed to withstand the increased working pressure of the common rail with injection rate shaping, which operates at 2000 bar. The design of the pistons, connecting rods and crankshaft, is optimized to reduce weight.
The shape of the combustion chamber and the reduced compression ratio means low NOx emissions and high performance, while the solenoid injectors atomize the fuel very finely for greater fuel efficiency and a quieter drive.
The engine features a novel variable geometry turbocharger integrated in the exhaust manifold. This reduces engine weight and improves the functionality of the exhaust gas treatment system.
This integrates the selective catalyst reduction functionality over a DPF substrate, in order to promote NOx reduction through ADblue injection, and particulate matter reduction through regeneration management. The 2.2-liter engine is Euro 6d-Temp standard compliant.
The upgraded 9-speed transmission uses new control software to refine drivability, improve launches, provide smooth power delivery at highway speeds, and improve fuel efficiency.
