Nissan CD17

Nissan CD17 diesel engineThe Nissan CD17 is a 1.7 L (1,680 cc, 102.52 cu-in) straight four, water-cooled naturally aspirated diesel engine from Nissan CD family. The engine was used on Nissan mid-size models from 1982 to 1998.

The Nissan CD17 engine has a cast-iron cylinder block, an aluminum cylinder head with SOHC (Single over-head camshaft) with two valves per cylinder. The compression ratio rating is 21.8:1. Cylinder bore and the piston stroke is 80 mm (3.15 in) and 83.6 mm (3.29 in), respectively. The CD17 produced 61 PS (45 kW; 60 HP) at 5,000 rpm or 55 PS (40.5 kW; 54) at 5,000 rpm of horsepower and 104 Nm (10.6 kg·m; 76.7 ft·lb) at 2,800 rpm of torque.

The breakdown of the engine code is as follows:

  • CD – Engine Family
  • 17 – 1.7 Liter Displacement
