The SD22 is a normaly aspirated 2.2L (2164 cc) Straight 4 diesel engine. It produces 70 hp.^{[verification needed]} It was used in the 1965-1971 Nissan Cedric It was also produced in the marine version MN 22 by Chrysler Marine after Nissan and Chrysler merged during the 1980's.

The SD22 was used in the Datsun 720 pickup trucks 1980 through 1983, producing 61 SAE brake horsepower @ 4000 rpm. The engine has three main bearings (an SD33 six minus two rear cylinders) and was never turbocharged like the phoffs car. In 1981, pistons were upgraded to a three ring piston with a steel compression ring carrier cast as part of the piston for improved durability.

The engine is popular in Australia utilized mostly as a reliable pump for remote livestock stations. It is also used in the Scout. To the best of my knowledge, the engine is still manufactured and imported by JESCO in California. JESCO also supplies parts. Blue Ridge Marine in Lake City, Washington, USA, 800.621.2215 handles the marine version.
