Opel Z10XE

Opel Z10XE EcotecThe Opel Z10XE is a 1.0 l (973 cc, 60.96 cu-in) straight-three four-stroke natural aspirated gasoline small-displacement engine from the GM Family O Ecotec engines, developed by Opel, at the time a subsidiary of General Motors. The engine was manufactured from 2000 to 2003.

This engine was a modified version of the engine Opel X10XE, under the emission standards Euro 4. The Opel Z10XE engine uses a light-weight cast-iron semi-closed deck engine block with a cast-iron crankshaft and aluminum head with dual chain-driven overhead camshafts (DOHC) and four valves per cylinder (12 valves in total). The engine is equipped with the EGR system.

Bore and stroke are 72.5 mm (2.85 in) and 78.6 mm (3.09 in), respectively. Compression ratio rating is 10.1:1. The Z10XE engine produces 58 PS (43 kW; 58 HP) at 5,600 rpm of maximum horsepower and 85 Nm (8.7 kg·m; 62.7 ft·lb) at 2,800 rpm of maximum torque.

The breakdown of the engine code is as follows:

  • Z – Euro 4 engine
  • 10 – 1.0 Liter displacement
  • X – Comression ratio from 10 to 11.5:1
  • E – Multi Point Fuel Injection system
