6.1L Engine
The 6.1L-liter V8 HEMI made its Jeep debut within the 2006 Grand Cherokee SRT8 which went on sale in January of 2006. When SRT powertrain engineers got down to develop a extra highly effective HEMI they had been conscious of the engine’s heritage, which led to adopting conventional HEMI engine cues together with an orange-painted cylinder block and black valve covers. SRT engineers who developed the 6.1L engine achieved extra horsepower by including extra cubic inches, rising the compression ratio, and redesigning the cylinder head, consumption and exhaust methods for higher circulation and elevated engine pace.

For extra displacement, SRT engineers bored out the diameter of the cylinders within the HEMI by 3.5 millimeters every as a way to improve the full displacement to six.1 liters from 5.7 liters. Compression ratio was additionally elevated to 10.3:1 from 9.6:1, rising engine effectivity and energy. Cylinders are honed with torque plates to make sure a more true bore, to cut back friction and improve energy.

Engine respiratory was elevated with new higher-flow cylinder heads, a specifically designed consumption manifold, and exhaust headers with particular person tubes encased in a stainless-steel shell, all distinctive to the 6.1-liter HEMI engine. Larger-diameter valves and reshaped ports within the heads enable for maximized air circulation. The consumption manifold was designed with bigger diameter and shorter runners for higher-speed tuning. Exhaust runners enable elevated fuel circulation whereas sustaining quick catalyst light-off, whereas including 12 horsepower over the 5.7-liter engine’s solid manifolds. Exhaust is routed by a big diameter (2.75-inch vs. 2.5-inch) exhaust system with 3.5-inch chrome ideas.

To additional improve horsepower, performance-oriented camshaft profiles had been developed to permit extra air out and in of the cylinders, in addition to handle the next engine pace. A billet metal, high-strength camshaft options extra overlap and elevate for higher efficiency. Silent chain, 5-bearings. Bi-metal materials besides quantity 3 Babbit. Deep-fillet rolled journals for improved fatigue life, press match damper to reduce torsional vibration.

SRT engineers elevated the HEMI’s peak energy output engine pace by almost 20 % to six,000 revolutions per minute (rpm) from 5,000 rpm. Intake and exhaust valve stems are hole, and the exhaust valve stems are full of sodium to assist dissipate warmth extra effectively.

The high-performance SRT 6.1-liter HEMI is strengthened with redesigned elements, together with a bolstered engine block, cast micro-alloy metal crankshaft with retuned damper, high-strength powdered metallic connecting rods and floating-pin pistons. The pistons are cooled by oil squirters, aimed on the underside of every piston to assist piston cooling for engine sturdiness. A particular oil pump strain reduction valve is added to accommodate the squirter oil circulation. The oil pan and windage tray are modified to handle oil return to the pan sump at excessive engine speeds and enhance energy.

  Type and Description 6.1-Liter, HEMI® V-8, 90-degree V-type, liquid-cooled. The improvement of the SRT 6.1-liter HEMI V-8 began with a world-class basis – the Chrysler Group’s 5.7-liter HEMI V-8 engine. From there, a crew of SRT powertrain engineers built-in race-proven engine applied sciences to create the highly effective new SRT 6.1-liter HEMI. Bore x Stroke 4.055 x 3.58 (103 mm x 90.9 mm). To get extra air out and in of the cylinders, SRT engineers bored out the diameter of every cylinder by roughly 3.5 millimeters as a way to improve the full displacement from 5.7 liters to six.1 liters. Cylinders are honed with torque plates to make sure a more true bore, to cut back friction and improve energy. Camshaft A billet metal, high-strength camshaft options extra overlap and elevate for higher efficiency. Silent chain, 5-bearings. Bi-metal materials besides quantity 3 Babbit.

Fuel Requirement Premium 91 octane (R+M)/2 really useful Headers / Exhaust Individual tubes encased in a stainless-steel shell. Exhaust runners enable elevated fuel circulation whereas sustaining quick catalyst light-off, whereas including 12 horsepower over the 5.7-liter engine’s solid manifolds.The 6.1L exhaust system makes use of two catalytic converters situated within the entrance exhaust pipe, and a single muffler and a duel tailpipe/resonator meeting. The entrance exhaust pipe/catalytic converter meeting is a hydra-form skinny wall air hole design. This design is used to cut back warmth, noise and enhance emissions. Knock sensors To management the combustion course of, SRT engineers fine-tuned the engine administration system utilizing twin large band knock sensors with premium gas. Lubrication Pressure feed – full circulation filtration Manifolds Continuing its air-pumping effectivity, engine respiratory is improved with specifically designed consumption and exhaust manifolds. The solid aluminum consumption manifold is designed with shorter, larger-diameter and tapered runners for high-speed tuning. Internal runners are core-dipped to easy the runner end and enhance air circulation. The exhaust manifolds are geared up with ball flange retailers to guarantee a decent seal and pressure free connections. Max. Engine Speed 6400 rpm (electronically restricted) Oil Capacity 7 qt. (6.6L). The oil pan and windage tray are modified to handle oil return to the pan sump at excessive engine speeds and enhance energy. Oil Pressure Minimum, at curb idle pace, 04 psi (25 kPa) / @ 3000 rpm, 25-110 psi (170 – 758 kPa). Oil squirters Aimed on the underside of every piston, added to assist piston cooling for engine sturdiness. A particular oil pump strain reduction valve is added to accommodate the squirter oil circulation. Pistons and rods Larger-diameter, flat-top pistons with high-load functionality are specified to deal with the SRT 6.1-liter HEMI’s compression ratio, which was elevated to 10.3:1 from 9.6:1. Connecting rods are redesigned and make use of higher-strength powder metallic materials. New floating piston pins are launched to deal with increased masses.

Active full-time single-speed with variable torque, strong electronically managed clutch pack in heart differential and open entrance and rear differentials. The NV146 switch case gives On-Demand Active Four-Wheel Drive for optimum traction in a variety of situations. The switch case makes use of the electronically managed clutch pack to distribute between 0% and 50% of the accessible torque to the entrance axle. The NV146 electronics present an energetic system as a result of it will possibly anticipate and forestall slip.The NV146 single-speed switch case gives the next advantages:

 

  • No shift lever or driver interplay required.
  • On-demand four-wheel drive gives easy operation and automobile stability underneath all situations as a result of torque is continually being transferred.
  • Even torque distribution gives traction to take care of ahead movement underneath most situations.
  • The Brake Traction Control System (BTCS) works in tandem with on-demand four-wheel drive. BTCS gives resistance to any wheel that’s slipping to permit extra torque switch to wheels with traction.
  • Robust design and improved sealing improve reliability.
Operation Controls for the NV146 switch case energetic clutch (torque biasing machine) are situated within the Final Drive Control Module (FDCM) and communicated on the CAN C bus. The FDCM screens wheel speeds on the entrance and rear axles to detect wheel slippage. An entire automobile dynamics mannequin calculates slip at every tire for given vehicle-operating situations. The clutch pack within the switch case is engaged to reduce the pace distinction between the entrance and rear axle, leading to torque switch to the axle with increased traction. The electronically managed moist clutch pack makes use of an electrical motor to actuate a sector plate. The sector plate actuates a clutch lever that applies regular power to the multi-disc moist clutch pack bridging the differential. The clutch discs are alternately splined to the entrance and rear driveshafts. When regular power is utilized to this clutch pack, torque is transferred to equalize pace variations between entrance and rear axles.
