Straight-four
[edit]SD20
[edit]The SD20 is a naturally aspirated 2.0 L (1,991 cc)straight-fourdiesel enginewith a bore and stroke of 83 mm × 92 mm (3.27 in × 3.62 in). It had threemain bearings.The Diesel versions of theNissan Cedricin the 1960s until the early 1980s used this engine, which produces 60 PS (44 kW) at 4,000 rpm.[1]It was first seen in a passenger car in June 1964, when it was fitted to the QGS31 Nissan Cedric.
SD22
[edit]First appearing in 1963 the SD22 is a naturally aspirated 2.2 L (2,164 cc) inline-four diesel engine. It is a stroked version of the smaller SD20 up to 100 mm (3.94 in). It produces 65 PS (48 kW) at 4,000 rpm as fitted to the 1983 430-series Nissan Cedric.[1]It was first used in a passenger car with the 330-seriesNissan Cedricfrom June 1977. It was also produced in a marine version MN 22 by Chrysler Marine under license during the 1980s.
The SD22 was used in the Datsun 720 pickup trucks from 1980 through 1983, where it produced 61 hp (45 kW) (SAE) at 4,000 rpm. Like its lesser SD20 relative (but unlike its SD33 six-cylinder derivative) it has three main bearings and was never available with turbocharging. 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. The engine may still be manufactured and imported by JESCO in California. JESCO also supplies parts. The marine version, using a water-cooledexhaust manifoldand expansion tank is also still available from other manufacturers.
