Applications:
The 1KZ-TE is a, 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. The bore and the stroke are, with a compression ratio of 21.2:1. Maximum output is at 3600 rpm with a maximum torque of ⋅m at 2000 rpm. The redline is 4400 rpm. Introduced as the replacement of the 2.4 2L-TE engine in Toyota's Light Duty Commercial Vehicles in Japan, it was first included in the 70-series Prado in May of 1993 followed by the Hiace and Hilux Surf in August of the same year. The 1KZ-TE also adopts the electronically controlled fuel injection, ETCS-i technology which is similar in basic construction to a modern gasoline injector, although using 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 KZN130, KZJ71W, KZJ78W, KZN160 and KZN165R.
The intercooler equipped version of the engine increases the output of the engine at 3600 rpm and a maximum torque of at 2000 rpm.
