The Suzuki M engine family is a line of automobile engines from Suzuki. Ranging in displacement from 1.3 L to 1.8 L, it is a modern engine line with dual overhead cams, 16 valves, and multi-point fuel injection (MPFI). Fully developed in-house following Suzuki's separation from General Motors, the M engine replaced the long-lived G engine family.[1]

M13A

[edit]

The M13A displaces 1.3 L (1,328 cc); bore and stroke is 78 mm × 69.5 mm (3.07 in × 2.74 in). It has a 9.5:1 compression ratio and two variants:

M13AA

[edit]

The M13AA is an automotive engine manufactured by Suzuki Motor Corporation. The M13AA is a 1.3 L (1,328 cc) inline-four cylinder, 16 valve VVT engine used in the Suzuki Jimny, Suzuki Swift & Suzuki Ignis from 2005.

  • Compression Ratio 9.5:1
  • 85 PS (63 kW) at 6000 rpm, 110 N⋅m (81 lb⋅ft) at 4100 rpm

M15A

[edit]

The M15A displaces 1.5 L (1,490 cc); bore is and stroke 78 mm × 78 mm (3.07 in × 3.07 in). This engine has a variable valve timing valvetrain. With a 9.5:1 compression ratio, it produces 100 PS (74 kW) at 5,900 rpm and 133 N⋅m (98 lb⋅ft) at 4,100 rpm. The M15A used in the Suzuki Ignis (HT81S) has a higher compression ratio of 11.0:1, and produces 112 PS (82 kW) at 6400 rpm and 143 N⋅m (105 lb⋅ft) at 4100 rpm.

M16A

[edit]

The M16A displaces 1.6 L (1,586 cc). Bore is and stroke 78 mm × 83 mm (3.07 in × 3.27 in). This engine has a DOHC variable valve timing valve train and a multipoint injection system. The engine had many iterations, depending on the car in which it was installed and the intended use of the car. The M16A engine uses a chain cam instead of a cam belt. General dimensions:

Application:

M18A

[edit]

The M18A is based on the M16A, with a larger bore. It is the only M-series engine to use a different bore.[1] It displaces 1.8 L (1,796 cc); bore and stroke is 83 mm × 83 mm (3.27 in × 3.27 in). This engine has a variable valve timing valvetrain. With a 9.6:1 compression ratio, it produces 125 PS (92 kW) at 5,500 rpm and 170 N⋅m (125 lb⋅ft) at 4,200 rpm.

Due to the engine block being based on the same casting, a M16A cylinder head can be bolted onto a M18a shortblock with minor modifications. This has been done by tuners, by installing a M18A block with the stock internals (crank, pistons and rods) in a Suzuki Swift Sport, in order to have more torque on the whole rev band.
