A new cylinder head achieved this, improving the intake and exhaust ducts. Also adopted were a new camshaft, a new exhaust manifold of a 3-1/3-1 type, two 2-inch diameter exhaust pipes, and three Weber DCOE 45-45 side-draft carburetors. The Torino and the Jeep Tornado engine continued production through 1982.
The cause of the problem was found to be one head bolt hole that was drilled too shallow at the factory, meaning the head bolt bottomed out and could never seal properly. In 1998, a thicker, multi-layer steel head gasket was introduced that eliminated this problem. General Specifications. Cylinder Configuration: In-line 4
The gross power and torque outputs decreased to 72 hp (54 kW; 73 PS) and 112 lb⋅ft (152 N⋅m), respectively, when the engine had a 6.9:1 compression ratio. Bore and stroke dimensions were the same as the L-head engine at 3 + 1 ⁄ 8 x 4 + 3 ⁄ 8 inches, giving 134.2 cu in (2,199 cc). [3] The F4-134 was introduced in 1950 in the Jeep Truck. [4]
It was an L-head design, with valves parallel with the cylinders. Initial power output was 60 hp (45 kW; 61 PS) at 4000 rpm and 105 lb⋅ft (142 N⋅m) of torque at 2000 rpm with 6.48:1 compression. [4] The L134 was phased out by the F-head Willys Hurricane engine beginning in 1950.
In 1986, the head underwent a minor revision: the head bolts were increased from 7/16 to 1/2 inch. From 1997 until 2002, it was marketed as the "PowerTech I4." [ 7 ] It was produced through 2002 for the Jeep Wrangler , as well as for the Dodge Dakota pickup that also featured the AMC/Jeep-designed four-cylinder as its standard engine on regular ...
2.5 L; 152.2 cu in (2,494 cc) inline-5, with two (pushrod-actuated) valves-per-cylinder and indirect fuel injection from either Bosch or Spica. 88 mm × 82 mm (3.46 in × 3.23 in). This engine is a five-cylinder version of the 2-litre HR488, and also uses KKK turbochargers. Applications:
The Chrysler Pentastar engine family is a series of aluminium (die-cast cylinder block) dual overhead cam 24-valve gasoline V6 engines introduced for the 2011 model year in Chrysler, Dodge, and Jeep vehicles.
They were later also used in some rear wheel drive cars like the Jeep Wrangler. The engines were produced in two major variants differing by their piston displacement: a 3.3 L; 201.4 cu in (3,301 cc) and a 3.8 L; 230.5 cu in (3,778 cc). The 3.3 was dropped after 2010 with the Chrysler minivans, and the 3.8 was dropped after 2011 with the Jeep ...
