Nissan A15 Engine Specifications
The Nissan A15 or A15S is an 1.5
l (1,487 cc) four-cylinder four-stroke gasoline engine from Nissan
A-family. The engine was manufactured by Nissan Motor Company from 1979
through 1998. The Nissan Vanette C22 with A15 engine was built in
Malaysia at the Tan Chong assembly plant in Segambut (Kuala Lumpur)
until 2010.
The A15 motor uses a lightweight cast-iron block and an aluminum
cylinder head, with overhead valves and single camshaft. Bore and stroke
were 76.0 mm and 82.0 mm. Compression ratio rating was
8.9:1 for California, 8.5:1 for Non-California and Canada models and
9.0:1 for industrial applications. The A15 was produced in various
ratings from 67 HP (50 kW) to 85 HP (63 kW).
The A15E engine with Electronic Port Fuel Injection system was offered
in Asian markets.

operated with spring and oil pressure. The rubber shoe type tensioner
insulates vibration of the chain and controls the tension of the chain.
