The Toyota KZ is one of Toyota's small passenger diesel engines.

1KZ-T

The 1KZ-T is a version of the KZ series engine that used a fully mechanical injector pump instead, 2982 cc, 4 cylinders, SOHC, 2 valve per cylinder turbo diesel engine. Compression ratio remains the same at 21.2:1. Maximum output is 123 hp at 3600 rpm and maximum torque is 296 Nm at 2000 rpm. Applications:

1KZ-TE

The 1KZ-TE is a 2982 cc, 4 cylinder, SOHC, 2 valves per cylinder turbo diesel engine with indirect injection. Bore and stroke are 96x103 mm, with a compression ratio of 21.2:1. Maximum output is 130 PS at 3600 rpm with maximum torque of 287 Nm⋅m (212⋅ft) at 2000 rpm. Redline is 4400 rpm. Introduced as the replacement of the 2.4 2LTE engine in Toyota's Light Duty Commercial Vehicles in Japan, it was first introduced 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 (Electronic throttle control System - intelligent) 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 (Japan market), KZJ71W, KZJ78W, KZN160 and KZN165R (Australian & South African delivered model). The intercooler equipped version of the engine increases the output of the engine 140 PS [Aust. 130 hp] at 3600 rpm and maximum torque of 343 Nm at 2000 rpm. Applications:
