Spark plugs, pistons, connecting rods, crankshafts and sumps are the main parts of Jeep engines. The pistons move up and down inside the cylinder, and Jeeps may have four, six or eight cylinder engines in flat, in-line or V configurations.
Engines must have spark, air and fuel to run. The spark plugs provide the spark that ignites the air and fuel mixture, causing combustion. The intake and exhaust valves open and close to let air and fuel into the engine and release exhaust gas. The connecting rod connects the pistons to the crankshaft, and the crankshaft moves the pistons up and down. Piston rings prevent the air and fuel mixture and exhaust gas from entering the sump and keep oil in the sump from entering the combustion area of the engine.
Jeep is a subsidiary of Fiat Chrysler Automobiles. The automobile maker only produces sport-utility and off-road vehicles, as of October 2015, but previously had pickup trucks in its line up, including the Honcho, J-20 and Comanche models. The modern Jeep Wrangler features solid front and rear axles for durability and strength while off-road driving and has a 3.6 liter Pentastar V6 engine that produces 285 horsepower and 260 pound-feet of torque. This engine allows drivers to get an estimated 21 mpg on the highway and 17 mpg in the city.
