The Toyota SZ engine family is a series of straight-4 piston engines with a forward-facing exhaust. [1] Toyota Motor Manufacturing (UK) in Deeside produces SZ engines for the Yaris. [2] All three types of the SZ engine are built in Tianjin FAW Toyota Engine Co., Ltd. (TFTE) Plant No. 1 in Xiqing District, Tianjin, China. [3] [4] The 2SZ-FE and 3SZ-FE variations are also manufactured by PT Astra Daihatsu Motor's Karawang Engine Plant in Indonesia. [5] [6] [7]
The 1SZ-FE was jointly developed by Toyota and Daihatsu. It has 4 cylinders [1] It is 1.0 L (997 cc). 4 valve per cylinder. Bore and stroke is 69 mm × 66.7 mm (2.72 in × 2.63 in), with a compression ratio of 10.0:1. Output is 51.5 kW (69.1 hp; 70.0 PS) at 6000 rpm with 95 N⋅m (70 lbf⋅ft) of torque at 4000 rpm. It features VVT-i, off-set type crankshaft which reduces friction losses and narrow-angle valves. Engine weight of 68 kg (150 lb); was achieved by using cast-iron cylinder block produced by cold-box method.
Applications:
The 2SZ-FE is 1.3 L (1,298 cc). Bore and stroke is 72 mm × 79.7 mm (2.83 in × 3.14 in), with a compression ratio of 11.0:1. Output is 64 kW (86 hp; 87 PS) at 6000 rpm with 122 N⋅m (90 lbf⋅ft) of torque at 4200 rpm. Daihatsu's internal code for this engine is labeled as K3-DE/VE and the turbocharged version as K3-VET.[ citation needed] The engine features VVT-i (except for K3-DE model). In China, this engine is usually known as the 4A13.
Applications:
The 3SZ-VE is 1.5 L (1,495 cc), introduced in October 2005. First installed in 2005 on the second generation Daihatsu Terios. Bore and stroke is 72 mm × 91.8 mm (2.83 in × 3.61 in), with a compression ratio of 10.0:1 and redline of 6500 rpm. Output is 80 kW (107 hp; 109 PS) at 6000 rpm with 141 N⋅m (104 lbf⋅ft) of torque at 4400 rpm. Commercial variant in Daihatsu Luxio and Daihatsu Gran Max has output of 97 PS (96 hp; 71 kW) at 6000 rpm with 13.7 kg⋅m (134 N⋅m) of torque at 4400 rpm. [8] It features VVT-i.
