The Isuzu Trooper is a mid-size SUV that was produced by the Japanese automaker Isuzu between 1981 and 2005. It was exported internationally as the Isuzu Bighorn, Isuzu Trooper, Isuzu Trooper II, Caribe 442, Acura SLX, Chevrolet Trooper, Subaru Bighorn, SsangYong Korando Family, Honda Horizon, Opel/Vauxhall Monterey, Holden Jackaroo/Monterey and HSV Jackaroo. In total, there were two generations of this vehicle: the first, produced between 1981 and 1991; and the second (UBS) produced between 1991 to 1997, with a substantial refresh in 1998. Its production ended in 2005. The Trooper began as a rather basic and somewhat underpowered on- and off-road vehicle, offered only with four-cylinder motor, four-speed manual transmission, and part-time four-wheel drive. The first generation evolved to add both amenities and luxuries, including optional air-conditioning, power windows, and a more powerful V6 engine. The second generation was even more refined and available in two-wheel drive as well as four. ==First generation (1981–1991)== The first-generation Trooper was available as a three- or five-door, with a solid 4.555:1 rear axle and an independent front suspension. In the Japanese market, the car was originally introduced as the "Isuzu Rodeo Bighorn", but the "Rodeo" part of the name was soon dropped. Early engines included a 2.0-liter gasoline and a 2.2-liter diesel, lightly powered even by early 1980s standards for the vehicle's empty weight. The four-wheel-drive system was engaged by operating a three-position shifter adjacent to the transmission shifter. Both Aisin manual-locking and Isuzu's own auto-locking hubs were employed. In 1986, Isuzu introduced the 4ZD1 four-cylinder 2.3-liter engine. Apart from higher power, changes to the previous engine included a Kevlar timing belt replacing the previous chain, and a larger two-barrel carburetor. This engine eventually proved somewhat problematic with a high incidence of burned valves due to poor coolant flow design of the overhead cam/valve head with mechanical lifters. A later head casting improvement by an Italian firm corrected this problem through improved coolant flow. Also available only for 1986 in the US was the 2.2l C223T turbocharged diesel engine, using a Garrett turbocharger. It was not a popular option because of the low power generated, and furthermore is notorious for a weak bottom end, the connecting rods not originally designed for the increased thermal and mechanical stress of forced induction. Because of those problems, Isuzu changed the 4ZE1 for 1988 and used the standard 2.8L GM V6 for 1989 until their own new V6 engines could be manufactured. In 1987, the rectangular headlights were introduced. For 1988, Isuzu introduced a 2.6-liter (4ZE1) ''I-TEC'' fuel-injected engine for the US market. In 1989, an optional General Motors 2.8-liter pushrod V6 borrowed from the Chevrolet S-10 pickup was also available. Manual transmission equipped models had a gear driven transfer case with a 2.28:1 low range ratio; models equipped with the 2.6-liter four-cylinder engine and automatic transmission had a 2.66:1 low range transfer case. Later first-generation models offered an optional four-speed automatic transmission. Models from 1988 to 1991 were equipped with live rear axles and four-wheel disc brakes. Overseas model engines included the Isuzu C223 (2,238 cc), C223T (a turbocharged version of the same) and in the late 80s naturally aspirated and turbocharged 2.8 L 4JB1 diesel versions, all straight-four engines. The turbocharged 2.8 originally produced , not much more than the of the considerably smaller C223T due to new stricter emissions standards. Later versions with intercoolers fitted offered as much as . In 1989 only, a short-wheelbase (90-inch) Isuzu Trooper was imported to the US market as the Trooper. All of these short wheelbase Troopers were equipped with 2.6-liter fuel-injected inline-four engines, 4.77:1 differential gears and 15×7-inch aluminium alloy "snowflake" pattern wheels. Automatic and manual transmissions were offered. In Central America, Troopers were offered with removable roofs and a higher wheel clearance. Powertrain options included the Isuzu 2.8-liter turbo diesel. In 1988, SsangYong Motors started licensed production of the Isuzu Trooper and sold it as the Korando Family, and was only marketed in South Korea, Scandinavia, Southeast Asia and to a lesser degree South America. It used the same 2.2 L diesel engine but later versions used both the 2.3 L Mercedes-Benz turbodiesel engine and the natural aspirated Peugeot 2.5 L diesel engine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Isuzu Trooper」の詳細全文を読む スポンサード リンク
