This is wat i found somewhere on net.. seems interesting as swift and liana engines are same:
The Swift's engine is a new aluminum, DOHC, 16-valve, naturally aspirated, fuel-injected inline four-cylinder unit designated M13A. It obtains a total displacement of 1328 cm3 with over-square internal dimensions of 78.0-mm (3.07-in) bore and 69.5-mm (2.77-in) stroke. The cylinder block is aluminum into which semi-wet cast iron liners are pressed, as consistent with the Suzuki aluminum block construction practice. The cylinder bore is machined with a dummy head bolted on. The block is a deep-skirt design, with two additional bolts securing each of three center bearing caps. The forged steel crankshaft is fully balanced with eight weights. Dual overhead camshafts are driven by a single-stage silent chain of 8.0-mm (0.3-in) pitch, and in turn act on four valves per cylinder via bucket-type tappets, with clearance adjustment achieved by a shim inserted atop the tappet. The intake camshaft is fitted with a vane-type VVT-i continuously variable timing device, which alters timing within a range of 60°.
