Nissan A10 Engine Specifications
The Nissan A10 is an inline 1.0 liter (988 cc)
four-cylinder, four-stroke cycle gasoline engine from Nissan A-family,
released in September 1966 for Datsun 1000 (1967 model year).
The A10 engine produced 55 HP (41 kW, 56 PS) of max power at 6,000 rpm
and 75.5 Nm (56 lb-ft) of peak torque at 4,000 rpm (on Datsun Sunny B10,
JDM) and 61 HP (45.5 kW, 62 PS) of max power on Datsun 1000. Bore and
stroke were 73.0 mm and 59.0 mm. Compression ratio rating
was 8.5:1.
In September 1969, the Datsun 1000 Coupe was introduced. This model was
equipped with an updated version of the A10 with a new carburetor and
increased to 9.0:1 compression ratio. This new motor produced 66.6 PS
(66 HP, 49 kW) of max power. Later versions of A10 engine produced 58 HP
(43 kW, 58 PS). The A10 was used in the Nissan Sunny B10 (Datsun 1000)
and B20 from 1967 to 1970, Nissan Cherry E10 (Datsun 100A) from 1971 to
1976.

| CYLINDER BLOCK |
The A10 has a cast-iron cylinder block utilizes a three bearing
supported system. The cylinder block is provided with a baffle plate and
a steel net to reduce oil consumption. The cylinder bore is 73.0 mm
(2.87 in) and stroke is 59.0 mm (2.32 in).
The crankshaft is supported by three main bearings.
These main bearings are lubricated through oil holes which intersect the
main oil gallery in parallel with cylinder bores. The A10 uses flat head
pistons. The piston pin is connected to the piston by a full floating
fit and to the connecting rod by a press fit.
Full pressure lubrication is directed to the connecting rod through
drilled oil passages from the adjacent main bearing journal so that oil
is supplied to give maximum lubrication just before a full bearing load
is applied.

| CYLINDER HEAD |
The valve system has a push rod type rocker arm which uses the single
type valve springs.
The camshaft is supported by five camshaft bearings. Camshaft bearings
are lubricated through oil holes which intersect the main oil gallery of
the cylinder block. Concentric passages are drilled in the front and
rear parts of the camshaft for supplying oil to each cam lobe through an
oil hole drilled in the base circle of each lobe. A lubricant is
supplied to the front oil gallery from the second camshaft bearing. From
the center camshaft bearing, a lubricant is supplied to the valve rocker
shaft through the center rocker shaft bracket.
The camshaft is driven with a double row roller chain from the
crankshaft. The tension of the chain is controlled by the chain
tensioner which is operated with spring and oil pressure. The rubber
shoe type tensioner insulates vibration of the chain and controls the
tension of the chain.
The intake manifold has two openings: one is located on the primary side
and the other on the secondary side.
The exhaust manifold has a heat control valve which assures stable and
smooth engine running after starting in cold season. The manifold is
connected to the exhaust pipe by flangers, which completely eliminate
exhaust leaking.
