Chrysler 2.0L Turbo GME Hurricane Engine: Specs, Problems, and Reliability

Chrysler 2.0L Turbo GME Hurricane Engine: Specs, Problems, and Reliability. The 2.0 L GME T4 Hurricane turbo engine is a 2.0-liter inline four-cylinder turbocharged gasoline engine with direct fuel injection. This engine is part of the Global Medium Engine (GME) architecture family members created due to the powertrain division of the Fiat Chrysler Automobiles (short for FCA) group. The American version, made due to the FCA US division, was introduced first in the 2018 Jeep Wrangler and a year later became available for the Jeep Cherokee.

This new engine has a low-pressure, sand-cast aluminum cylinder block with cast-iron liners. The engine block is an open deck design and different from European engines with a closed deck used in Alfa Romeo’s cars. The 2.0 L GME engine has a lightweight crankshaft that seats with an offset from cylinder bores. The crankshaft offset reduces cylinder wall side loading since the connecting rod is more vertical during the power stroke. The engine block is also equipped with a low-friction roller bearing equilibrium shaft and a variable displacement two-stage oil pump.

Two-stage oil pump supplies high-pressure mode only under high-load engine operation and low-pressure oil during typical driving conditions. It also sents oil for the piston cooling jets (piston oil squirters), fitted with each cylinder bore to control piston temperatures and reduce spark knock. Pistons are cast aluminum with four valve pockets and plasma-coated piston rings.

In addition to the block, there is a cast aluminum alloy cylinder head. The 2.0 Hurricane head includes four valves per cylinder, sodium-filled exhaust valves, a central injector, MultiAir valvetrain with dual overhead camshafts (DOHC), high tumble intake ports, and a water-cooled, integrated exhaust manifold. The intake and exhaust camshafts are driven by a low-friction timing chain (an inverted tooth chain) and equipped with dual Variable Valve Timing (VVT) system. The engine uses hollow shafts with perfected cam journals to reduce weight (3.5 lbs less) and improve durability.

The 2.0 L GME T4 engine uses a direct injection system. The high-pressure fuel pump produces up to 2,900-psi for the high-pressure common-rail injection system. This system injects fuel via multi-hole fuel nozzles inside the cylinders, supplying better fuel atomization and allowing for more precise fuel delivery than port injection. The next feature improving both performance and efficiency is a turbocharged intake. There is a twin-scroll, low-inertia turbocharger with an electronically actuated wastegate.

It is attached to the cylinder head as the exhaust manifold is integrated into it. The integrated and water-cooled exhaust manifold reduces exhaust temperatures increasing turbocharger longevity, and accelerates engine warming up. The intake has a built-in water/air charge intake air cooler.

The intake air cooler, throttle body, and turbocharger use a separate cooling circuit. The cooling system also presents a variable flow water pump and an electric auxiliary water pump. The exhaust gas recirculation (EGR) system is water-cooled also.

2.0 L GME turbo fours in some applications use a belt-starter-generator (BSG) to help the engine at lower revs. This eTorque system also delivers better auto stop/start performance and improves low-end throttle response before the turbo spools up. The engine complies with all modern emission standards thanks to the GPEC4 engine-management system with a close-coupled catalyst, wide range O2 sensor, and C-EGR system.

Due to the combination of high compression ratio (10:1) and turbocharging, the turbo hurricane requires minimum unleaded regular, 87 octane (R + M)/ 2; 91 octane or higher recommended for optimum fuel economy and performance. The 2.0 turbo Hurricane is a good alternative to the Chrysler 2.4-liter engine and 3.6 L Pentastar V6.

Jeep 2.0 GME T4 turbo Engine Problems and Reliability

The engine just appeared on sale, and it’s hard to say about its long-run reliability. For the most part, owners complain that the engine light has started after several hundred/thousand miles on a new car. And the reasons for this are very diverse. Perhaps a failed sensor, loose hoses, or connectors that indicate poor build at the factory and subsequent quality control. This can be explained by the fact that the engine is new and complex, consists of many parts, and takes time to test and resolve upcoming issues.
