Global Application Features of KB, a New Gasoline Engine for Compact Vehicles

The main purposes of the KB variant engine development were not only to reduce fuel consumption or to enhance reliability & quality but also to make better productivity for global manufacture. This paper introduces technical approaches of KB, higher thermal efficiency, better performance and emissions, and well balanced product design with such high energy efficiency, and low-cost and global application. Maximum brake torque per displacement is 7% higher and overall engine weight is lighter by 24kg than an existing 1.3L engine. Design feature includes compactness, low noise characteristics and universal production design considered with globally purchasable materials and simple manufacturing requirement. These contribute short production preparation period and short production task time at Suzuki's key overseas local factories e.g., Maruti Suzuki India Limited.
