• SKYACTIV technologies- An Overview • 1. SKYACTIV-GHighly-efficient direct-injection gasoline engine that attainsthe highest gasoline engine compression ratio of 14.0:1 with zero knocking. • It is used for mass production of vehicles to achieve a high compression ratio • An improved engine efficiency owing to the high compression combustion, that results in 15 percent increase in fuel efficiency and torque. • A 4-2-1 exhaust system, multi-hole injectors, cavity pistons and other innovations help in achieving the high compression ratio. • 2. SKYACTIV-DA clean diesel engine which would meet global emissions regulations without costly NOx after treatments — urea selective catalytic reduction (SCR) or a Lean NOx Trap (LNT) — owing to the world’s lowest diesel engine compression ratio of 14.0:1 • 20 percent better fuel efficiency • A novel two-stage turbocharger realizes smooth and linear response from low to high engine speeds and greatly increases low- and high-end torque • Follows global emissions regulations, without expensive NOx after treatment

• 3. SKYACTIV-Drive Highly efficient automatic transmission that achieves excellent torque transfer efficiency through a wider lock-up range and features the bestfeatures of all transmission types • It has all the benefits of traditional automatic transmissions,consistently variable transmissions, and dual clutch transmissions • A dramatically widened lock-up range upgrades torque transfer efficiency and realizes a direct driving feel that is equivalent to a manual transmission • A 4-to-7 percent improvement in fuel economy in comparison to the current transmission • 4. SKYACTIV-MTA light and compact manual transmission with crispy and light shift feel like that of a sports car. • Short stroke and gives a light shift feel • Reduced size and weight due to a revised structure • More efficient vehicle packaging owing to its compact size • Reduced internal friction leads to economical fuel efficiency

• 5. SKYACTIV-BodyA lightweight, highly-rigid body with an excellent crash safety execution and high rigidity for greater driving pleasure • Highly rigid and lightness • Excellent crash safety performance and lightness • A “straight structure” in which each part of the frame is configured to be as straight as possible. Moreover, a “continuous framework” approach was adopted in which each section functions in a coordinated manner with the other connecting sections • 6. SKYACTIV-ChassisHigh-performance lightweight chassis which balances precise handling with a comfortable ride feel to realize pleasure duringdriving. • If you want to take up CAD CAM course in Pune, then opt for CRB Tech Solutions .
