Suzuki in the U.K. is introducing a new engine for its popular Swift model
17 Sep 2014|5,640 views
The U.K. arm of Suzuki is planning to introduce a new 1.2-litre petrol unit for the Swift early next year. The new power unit allegedly incorporates Suzuki's latest technology that utilises twin fuel injectors for improved fuel economy. Known as Dualjet, the new technology has resulted in Swift attaining 27.9km/L on the EC Combined fuel consumption cycle, representing a 16 percent improvement over the current petrol engine, with emissions ratings of just 99g/km.
Utilising Dualjet technology that positions the fuel injectors very close to the engine inlet valves allows for a finer fuel mixture - which in turn provides a more effective transfer into the cylinder. 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 and facilitate smoother running.
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 type of Exhaust Gas Recirculation (EGR) system is used, which helps avoid abnormal combustion or 'knocking'.
The maximum power output is 88bhp with a slightly increased torque figure of 120Nm at 4,400rpm. Other modifications include slight alterations to gear ratios for greater flexibility on the road, and the addition of Engine Auto Stop-Start (EASS).
