Chronology
Predecessor
SuccessorSuzuki R engine (K6A)

The Suzuki K engine family is a series of all aluminium inline-three or four cylinder automobile engines from Suzuki, introduced in 1994. The displacement is ranging from 0.7 L to 1.5 L. This is a timing chain head driven DOHC 4-valve per cylinder engine with VVT and using multipoint fuel injection or direct injection fuel system.

Since 2013,[2] some of the K engines range has been upgraded with several new technologies. The upgrades including new two injectors per cylinder, smaller compression chamber, increasing the compression ratio, improving the thermal efficiency, redesigned water jacket shape, adding piston cooling oil jets, adoption of water-cooled EGR system and several other changes for fuel efficiency, this technology is known as Dualjet.[3] The direct injection with turbocharger variant is called Boosterjet.[4][5]

Furthermore, a start-stop mild hybrid technology with 12 or 48-volt electrical system known as Smart Hybrid Vehicle by Suzuki (SHVS) is also available for markets with stricter emission regulation, such as in Europe, Japan and India. This mild hybrid technology is helping to increase fuel mileage, providing optional acceleration and also reduce the emissions.[6][7]
