Nissan D engine explained

The Nissan D-series is an overhead valve series of engines which first appeared in 1964, with the 1.05-liter D engine. Similar to a number of British and other Datsun engines, it may have been derived from an Ohta design which also found its way into some Kurogane vehicles - both of these companies were swallowed up by Nissan in the early 1960s.

D (D10)

The D type engine was introduced for the 1964 update of the Datsun Cablight (A122). This engine displaces and is of an overhead valve design.^[1] Its internal dimensions are unknown, but the displacement is the same as the E-10 engine made by Tokyu Kogyo Kurogane from 1959 until 1962; this engine was originally developed by Ohta.^[2] The E-10 engine has a bore and stroke of NaN2NaN2;^[3] this is the same stroke as in the latter D11 engine. The D engine, unlike other Nissan engines of the period, also has its distributor mounted between the second and third cylinders rather than towards the back of the engine.^[1] Kurogane was taken over by Nissan in 1962 and the Datsun Cablight was a continuation of the Kurogane Mighty, which had already used the E-10 engine in the Mighty NC model.

Applications

• 1964 Datsun Cablight A122, A220

D11

The D11 is a 1138cc pushrod, three main bearing, inline-four with wedge combustion chambers, and a bore and stroke of NaN2NaN2, a compression ratio of 8.0:1, and was rated at 290NaN0 at 2800 rpm (D11-PU 41-U model). It weighed 137.50NaN0. Similar to the E & J series, and Austin A series in layout, it had a gear-driven cam drive similar to the larger SD series diesels; it was used in Datsun FG003 forklifts in the 1960s and then in the NFG101C-103C forklifts in the 1970s. These later industrial applications produce 270NaN0 at 2800 rpm.

Applications

• 1964–1968 Datsun Cablight A220 & A221

D12

The D12 is a 1189cc version of Nissan/Datsun's D-series inline-four. Also an overhead valve design, it produces 560NaN0 at 4800 rpm.^[4]

Applications

• 1968–1970 Datsun Cabstar A320
