The MA is a straight-4 SOHC 0.9 L, 1.0 L, or 1.2 L engine introduced in 1982 by Nissan, intended primarily for the K10 series Micra/March model. It shares design similarities with the older E engine, with an 8-valve hemispherical cylinder head but differs in that it uses an aluminium cylinder block. Unusually, the specified ignition timing for the MA10 running on the specified 90 RON gasoline was 2 degrees after top dead centre, reflecting a very high flame speed in the compact combustion chambers.
