Suzuki will introduce the Swift hatchback with a new petrol engine in the European markets in 2015. The vehicle will get the new 1.2-litre petrol unit that incorporates Suzuki’s latest technology that utilises twin fuel injectors for improved fuel economy.
The new technology, known as Dualjet, allows the Swift to offer an impressive 65.7mpg of fuel economy on EC combined fuel consumption cycles (around 24kmpl). Another benefit of Dualjet technology is reduced CO2 emission of 99g/km. Utilising Dualjet technology that positions the fuel injectors very closer to the engine inlet valves allows for a finer fuel atomisation (or 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 company has modified the piston crowns to achieve higher air turbulence inside the cylinder and the pistons have cooling oil jets to reduce internal temperatures. Moreover, a new type of Exhaust Gas Recirculation (EGR) system is used which helps avoid abnormal combustion or ‘knocking’
The engine is capable of producing a top power output of 90PS and a peak torque of 120Nm at 4,400rpm. The vehicle also gets slightly modified gear rations and additional Engine Auto Stop Start. The new Dualjet 1.2L engine for Swift will initially be available as an optional engine choice on SZ4 two wheel drive models and will cost around an addition £500 (INR 50,000).
