Opel X10XE

The Opel X10XE is a 1.0 l (973 cc, 60.96 cu-in) straight-three four-stroke natural aspirated gasoline small-displacement engine developed by Opel, at the time a subsidiary of General Motors. The engine was manufactured from 1997 to 2000.

The X10XE 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 Bosch Motronic M1.5.5 ECU (Euro II).

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 X10XE engine produces 54 PS (40 kW; 54 HP) at 5,600 rpm of maximum horsepower and 82 Nm (8.4 kg·m; 60.5 ft·lb) at 2,800 rpm of maximum torque.

The breakdown of the engine code is as follows:

• X – Euro 2 engine
• 10 – 1.0 Liter displacement
• X – Comression ratio from 10 to 11.5:1
• E – Multi Point Fuel Injection system
