The Nissan RD engine series is basically a diesel version of the Nissan RB engine, only available in a single overhead cam, six-cylinder layout. It was the successor to the Nissan LD and SD six-cylinder engines and was joined by the six-cylinder Nissan TD engine.

From 1997 onwards the turbocharged versions were fitted with electronic fuel injection. The turbodiesel version known as the RD28T (or RD28ET with electronic fuel injection) and were also fitted to the Nissan Safari (also known as the Nissan Patrol) off-road vehicle.

Since the Nissan RD engine is based on the Nissan RB engine, they have many similarities and many parts are interchangeable. The engine block was similar to the RB30 engine except it had more material, was heavier and had an 85 mm bore vs the 86 mm bore of the RB30 and a 83 mm rather than 85 mm stroke. One issue is that the stronger vibrations from the diesel engine can loosen the crank/harmonic balancer bolt (originally from the RB engines) which in turn becomes loose or falls off, causing major engine damage. It is recommended to use thread locking fluid when installing.

The cylinder head was of a non-crossflow design, meaning that the exhaust and intake ports were on one side of the cylinder head.
