Suzuki has added an improved 1.2 litre K12B engine to the Suzuki Swift range in markets like the UK. The new engine (a £500 option) is the new Dualjet engine previously offered only for the Japanese market.
The new Dualjet engine increases power over the regular 90 PS 1.2 litre engine to 94 PS, and torque is up from 118 Nm at 4,800 to 120 Nm at 4,400 rpm.
The Dualjet engine uses twin fuel injectors per cylinder, an increased compression ratio of 12.0:1 (versus 11.0:1), and the addition of engine auto start/stop. It’s also paired with a gearbox that has revised ratios.
The new setup positions the fuel injectors very close to the engine inlet valves allows for a finer fuel atomisation. Internal modifications to the engine include the use of a new type of inlet port and combustion chamber with other mechanical parts also modified to reduce frictional losses.
The piston crowns have also been modified with a slight bowl shape to achieve higher air turbulence inside the cylinder, and the pistons have cooling oil jets to help reduce internal temperatures. Additionally, a new Exhaust Gas Recirculation (EGR) system helps avoid abnormal combustion or ‘knocking’.
In Malaysia, the Suzuki Swift comes with a larger 1.4 litre engine that produces 94 PS and 130 Nm. The DualJet engine matches it in horsepower, but is down 10 Nm of torque.

now that’s real jet engine for you..
CFE = cannot fuel efficient (9.1L/100km = 10.9 km/Liter)

Proton king of road and RV.
Proton Iriz can smoke this car anytime.
Swift = swiper, Iriz = idealism
well, that escalated quickly…
Well done, again sushi cars rock!
While everyone is lower down the engine size, increase the compression ratio and add in more features like dual inject, EGR to improve power output and fuel consumption. We still see some un-launched B segment hatchback paired with 1.6 engine.
2 possibilities only:
1. Engine is powerless
2. Drivers are power-hunger
Is it coming to msia?
it doesn’t change much? what gives?
of course diesel use higher compression.
Not bad for 1.2 NA engine. City car.
isn’t it time the Swift have a totally new exterior design… too many face lifts is making it look like joan rivers! Same face… just shinier
The emission requirement simply just make whatever car looks retarded.
bro, the videos error lah..
