Suzuki K engine GudangMovies21 Rebahinxxi LK21
The Suzuki K engine family is a series of automobile engines from Suzuki, introduced in 1994. Displacements range from 0.7 L to 1.5 L. All engines have aluminium cylinder blocks with three or four cylinders in-line. Cylinder heads have two overhead camshafts, driven by chain, and four valves per cylinder. Fuel is gasoline/petrol, metered by multipoint fuel injection or direct injection. Some variants are turbocharged.
Since 2013, some of the K engines range have been upgraded with Dualjet technology. The upgrades include new two injectors per cylinder, increased compression ratio (improving the thermal efficiency), redesigned water jacket shape, piston cooling by oil jets, water-cooled EGR system and several other changes for fuel efficiency. The turbocharged variant with direct injection fuel system is called Boosterjet.
Furthermore, a mild hybrid technology with 12 or 48-volt Integrated Starter Generator (ISG) dubbed as Smart Hybrid Vehicle by Suzuki (SHVS) is available for markets with stricter emission regulation, such as Europe, Japan, India, Singapore and Mexico (marketed as Boostergreen). This mild hybrid technology helps to increase fuel mileage, providing optional acceleration and also reduces emissions. A strong hybrid variant with Motor Generator Unit (MGU) is available in Europe and Japan.

=This is the first K engine that appeared in 1994 and was discontinued in 2018. It is the smallest in the family and also the first K engine with VVT. This engine was available in several versions, such as naturally aspirated, turbocharged, lean-burn, CNG and strong hybrid. The hybrid version was also the first hybrid engine in the kei car class and only available for Suzuki Twin.
