1KZ-TE
The 1KZ-TE is a 3.0 L (2982 cc), 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. Bore is 96 mm and stroke is 103 mm, with a compression ratio of 21.2:1. Maximum output is 130 hp (97 kW) @ 3600 rpm with maximum torque of 287 N·m (211 lb·ft) @ 2000 rpm. Redline is 4400 rpm. First produced in 1993, it is still used in new model vehicles today. The 1KZ-TE also adopts the electronically controlled fuel injection, ETCS-i (Electronic Throttle Control System - intelligent) technology which is similar in basic construction to a modern gasoline injector, although utilizing considerably higher injection pressures, it is an indirect injection engine which gives it a significant efficiency and fuel consumption penalty. It was replaced in most markets with the 1KD-FTV engine which uses common-rail direct injection.
Used in KZJ71W, KZJ78W, KZN160 and KZN165R (Australian & South African delivered model).
The intercooler equipped version of the engine increases the output of the engine 145 hp (108 kW) [Aust. 130 hp (96 kW)] @ 3600 rpm and maximum torque of 343 N·m (253 lb·ft) @ 2000 rpm.
