Nissan A engine

April 30, 2023

The Nissan A series of internal combustion gasoline engines have been used in Datsun, Nissan and Premier brand vehicles. Displacements of this four-stroke engine family ranged from 1.0-liter to 1.5-liter and have been produced from 1967 till 2009. It is a small-displacement four-cylinder straight engine. It uses a lightweight cast iron block and an aluminum cylinder head, with overhead valves actuated by pushrods.

Chronology
PredecessorNissan C engine / Nissan E engine (OHV)
SuccessorNissan E engine (OHC)

The Nissan A engine design is a refined, quiet and durable gasoline engine. It appears to be a modern replacement of the earlier iron-headed Nissan C and Nissan E engines and is of similar dimensions. The 1960s E series was an all-new design from newly acquired Aichi Kokuki, and integrated Nissan's improvements to the BMC B-Series engine design of the 1950s (Nissan was a licensee of Austin Motor Company technology), mainly comprising changing the camshaft from the left side to the right side so removing the intrusion of the pushrods from the porting allowing 8 individual ports instead of 5 originally, and moving the oil pump from the rear of the camshaft to the right side of the block. As production continued, 1974 and newer A-series engines had different block castings, with relocated motor mount bosses.

A10: the first A-series engine

The A10 is a 1.0-liter (988 cc) engine, released in September 1966 in the 1967 model year Datsun 1000. The A10 featured a three main bearing crankshaft. Bore was 73 mm and stroke was 59 mm (same as the Nissan C engine). With a two-barrel Hitachi carburetor and an 8.5 to 1 compression ratio this engine produced 62 PS (46 kW; 61 hp) at 6000 rpm and 8.5 kg⋅m (83 N⋅m; 61 lb⋅ft). The Datsun 1000 Coupé, introduced in Sept 1968, was equipped with an uprated A10 engine boasting a free flowing dual outlet exhaust manifold with increased compression, now 9 to 1. With a revised carburetor, this engine produced 66 PS (49 kW; 65 hp). Export versions of the A10 as installed in the Datsun 100A produced 59 PS (43 kW; 58 hp) SAE at 6000 rpm and 8.3 kg⋅m (81 N⋅m; 60 lb⋅ft) at 4000 rpm.[1]

A belt-driven SOHC version of the A10 was built as the E10 into the early nineties.

Applications

A12 (1200): further refinements

The A12 is a 1,171 cc (1.2 L; 71 cu in) engine with a 73 mm (2.9 in) bore, like the previous A10 engine, but with its stroke increased to 70 mm (2.8 in). With five main bearings on a forged steel crankshaft, the engine is extremely smooth and durable. The two-barrel (twin-choke) Hitachi carburettor was significantly improved with the addition of a power valve circuit. The A12 engine produced 70 PS (51 kW; 69 hp) and 70 ft⋅lb (95 N⋅m) torque.

A special version of the A12 called the "A12 GX" engine, was available (A12GX or A12T for front-wheel drive applications). With twin Hitachi sidedraft carburetors, a longer duration camshaft and 10:1 compression ratio, it delivered 83 PS (61 kW; 82 hp) at 6400 rpm, up 20 percent from a standard A12 engine. The GX engine was offered in Japanese Domestic Market Nissan Sunny 1200 GX sedans and coupes. The identical specification A12T engine was offered in the front-wheel-drive Nissan Cherry X-1.[2]

An overbored version of the A12 was used in period race cars, including Nissan factory (works) racing Sunnys. Many were overbored from the original 73 mm (2.9 in) to 76.76 mm (3.022 in) using Tomei forged pistons for a displacement of 1,296 cc (79.1 cu in), while others used 76 mm (3.0 in) Datsun Competition forged pistons, for a displacement of 1,270 cc (78 cu in). These legendary engines competed in Japan's Touring Sedan (TS) class races against the 1200s archrival Toyota Starlet.[3]

Perhaps the most interesting variety of A series engines was the AY12 engine. This was a special race-only Nissan factory (works) racing version with a crossflow cylinder head.[4]

The AY12 was used in an under 1,300 cc (79 cu in)-class with a 76–76.8 mm (2.99–3.02 in) bore diameter. The intake valve was 40–41 mm (1.57–1.61 in) and exhaust valves were 33–34 mm (1.30–1.34 in). The pistons were also a special design and the valve rocker system was different from the standard A12 due to the use of a crossflow layout for the racing engine.

Applications

1974 redesign

For the 1974 model year, the A engine was modified, and all subsequent A engines use the new block style. Since there was increasing need for accessories like air conditioning, anti-pollution air pumps and the like, the distributor was moved from the front side of the engine to the middle of the block to make room for these accessories. Additionally, the motor mount positions were moved slightly. Nissan introduced its emission control technology, called NAPS (Nissan NAPS) with the redesign.

This "new" A12 retained the same bore, stroke and most other specifications of the previous A12.

Applications

A12A

The A12A is a 1.2-liter (1,237 cc) engine. It used a casting similar to the A12 and same stroke, but used a 75 mm bore (up from 73 mm), for an increase of 66 cc capacity. It too was of an overhead valve design. The A12A also uses a different (stronger) conrod with a larger diameter gudgeon pin.

The A12A shared a common block and crankshaft with the redesigned A12 and A13 engines.

Applications

A13 (1974): the first tall-deck A engine

The 1974 A13 is a 1.3-liter (1288 cc) engine with 73 mm bore like the A10 and A12 above, but stroke increased to 77 mm, and compression ratio reduced to 8.5:1. This engine features a "tall-block" with a deck height 15 mm (0.59 in) higher than previous A-series engines.

Applications

Making this engine a 75 hp (56 kW). An important fact is that this model only existed in the 1974 model year.

A13 (1979–1982) – short-deck engine

The redesigned A13 is a 1.3-liter engine. It used the same basic block casting as the A12 and same stroke of 70 mm, but used a 76 mm bore for a displacement of 1,270 cc. This engine was also used as the basis for a number of Formula Pacific and Formula 3 race engines.

Applications

A14

The A14 is a 1.4-liter (1397 cc) engine produced from the 1975 Model year through 2008. The bore was increased to 76 mm, up from 73 mm of previous A-series engines. Like the previous A13 engine, the A14 is a "tall-block" variant. It was produced in various ratings from 50 Horsepower to 85 hp (63 kW).

A twin-carburetor "GX" version of this engine (A14T) was available in some markets.

Applications
  • 1975–1978 Nissan Sunny B210 (140Y or B-210)
  • 1976-1978 Nissan/Datsun F-10
  • 1977.11-1982 Datsun Sunny HB310 (aka Datsun 140Y or Datsun 210)
  • 1977–1982 Nissan Pulsar N10 (aka Datsun/Nissan Cherry, Datsun 310) 92 PS (JDM)
  • 1977–1981 Nissan Stanza/Auster/Violet, 80 PS (JDM)[8]
  • 1978–1988 Nissan Vanette (PC120) – 75 PS (55 kW; 74 hp) at 5400 rpm[5] (originally only in 'Coach' passenger versions)
  • 1982–2008 Nissan 1400 LDV (model B140. Only sold in South Africa).
  • Datsun Forklift models (including turbocharged variant). Replaced the A15 normally aspirated engine due to emission controls implemented in the Asian markets.

A fuel-injected version (A14E) was offered in Asian markets in the B310.

A15 – Stroker motor

 
A15 in a Grove-Manlift

The A15 is a 1.5-liter (1,487 cc) engine produced from 1979 till 2009 where it was used in the Malaysian Vanette C22. The stroke was increased by 5 mm from the A14 engine to now measure 82 mm, while the bore remained 76 mm. It produces 80 PS (59 kW; 79 hp). It used only a different block casting number, but retained the same "tall-block" deck height, measurements and BMEP as the A14. In the Nissan B120 Sunny "RoadStar" truck it is capable of 49 mpg (17,3 km/L).[9]

A fuel-injected version of the A15 (A15E) was offered in Asian markets.
