Nissan D engine

The Nissan D-seriesis 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 1.0 L; 63.8 cu in (1,046 cc) 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 70 mm × 68 mm (2.76 in × 2.68 in);[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.

D11

The D11 is a 1.1 L; 69.4 cu in (1,138 cc) pushrod, three main bearing, inline-four with wedge combustion chambers, and a bore and stroke of 73 mm × 68 mm (2.87 in × 2.68 in), a compression ratio of 8.0:1, and was rated at 29 PS (21 kW) at 2800 rpm (D11-PU 41-U model). It weighed 137.5 kg (303 lb). 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 27 PS (20 kW) at 2800 rpm.[4]

Applications
  • 1958–1966 Datsun Cablight A20, A120, A220, A221

D12

The D12 is a 1.2 L; 72.6 cu in (1,189 cc) version of Nissan/Datsun's D-series inline-four. Also an overhead valve design, it produces 56 PS (41 kW) at 4800 rpm.[5]

Applications
gollark: So if you have a set of electric cars with small batteries - enough to travel within a city and near it - available for rent, and you don't suffer too much overhead from having to rent them out, that could conceivably be a good method of transport.
gollark: Electric cars are expensive *partly* because they need batteries for hundred-mile journeys, even though most actually won't be this long. And cars are kind of inefficient because most of the time they're left idling.
gollark: Personally, I think that local public transport and short-range intra-city electric cars would be worth considering.
gollark: Batteries' energy density isn't that great right now, sadly.
gollark: Also, they cause pollution indirectly, much like electric cars, although less.
