Understanding Skyactiv Technology

Skyactiv Technology is a suite of automotive advancements developed by Mazda, aimed at enhancing fuel efficiency and engine performance. This technology encompasses more than just engine improvements, extending to transmissions, body structure, and chassis design. Introduced in 2011, Skyactiv represents Mazda’s commitment to innovation and sustainability in the automotive industry.

Skyactiv Engines: Efficiency and Performance

Skyactiv-G Gasoline Engines

Skyactiv-G is Mazda’s innovative approach to the high-compression gasoline engine. These engines compress air and fuel in the cylinder to a higher degree before ignition, generating more power from a given amount of fuel. However, high-compression engines often face issues like spark knock, which can threaten efficiency and longevity. Mazda has addressed this by incorporating a small combustion well atop the piston and injecting fuel in precise, fast bursts, reducing the time for chaotic combustion. The G in Skyactiv-G stands for gasoline, highlighting its fuel-efficient design.

Skyactiv-D Diesel Engines

Skyactiv-D represents Mazda’s take on diesel engines, which traditionally use high compression to cause spontaneous combustion of air and fuel without a spark plug. Mazda has lowered the compression ratio to allow more time for the diesel fuel to mix with air before detonation. This, combined with precise fuel injection, results in a cleaner and more thorough burn. The lower compression ratio also helps in reducing emissions and improving overall engine efficiency.

Technological Innovations

Mazda’s Skyactiv engines are packed with technological innovations that set them apart. For instance, the Skyactiv-X engine combines the best of both gasoline and diesel technologies. It uses high compression to ignite the air/fuel mixture but retains a traditional spark plug to fine-tune the combustion process. This allows the engine to run lean, inhaling more air than fuel, which improves fuel efficiency and reduces emissions. The Skyactiv-X engine can reach a compression ratio of 16:1, an improvement over the 14.0:1 ratio of the Skyactiv-G, making it the first commercial petrol engine to use homogeneous charge compression ignition (HCCI).

Mazda’s Skyactiv technology is a testament to their commitment to innovation and efficiency, redefining what modern engines can achieve.

Skyactiv Transmissions: A New Approach

Skyactiv-Drive

Skyactiv-Drive represents Mazda’s innovative family of automatic transmissions, known as SKY-Drive. Mazda opted against dual-clutch technology due to its sub-optimal performance in certain scenarios. Instead, they re-engineered the conventional automatic transmission. This new design minimizes the role of the torque converter, using a multi-plate clutch to disengage it most of the time. The Skyactiv automatic transmission features six or eight forward gears and one reverse gear, along with a short torque converter and an integrated clutch.

Skyactiv-MT

Skyactiv-MT is Mazda’s line of manual transmissions. To achieve lighter shift effort and a shorter shift lever stroke, the lever ratio has been increased. However, to counterbalance the shorter internal stroke, a small module spline is utilized. This results in shift throws being reduced by 15%, making it the shortest shifting manual transmission in any passenger car. The triple-shafted gear train design, which places the reverse and first gears on the same shaft and uses a shorter secondary shaft, also contributes to weight reduction.

Advantages Over Traditional Transmissions

Skyactiv transmissions offer several advantages over traditional ones:

  • Enhanced Efficiency: The advanced control module in Skyactiv-Drive ensures quick responses and smooth acceleration, optimizing fuel economy.
  • Improved Performance: The re-engineered design of both Skyactiv-Drive and Skyactiv-MT provides superior performance in various driving conditions.
  • Weight Reduction: The innovative design of Skyactiv-MT contributes to a lighter overall transmission system.

Mazda’s Skyactiv transmissions redefine efficiency and performance, setting a new standard in the automotive industry.

Skyactiv-Body and Chassis: Redefining Vehicle Structure

Lightweight Design

Mazda’s SKYACTIV®-BODY is engineered to be 8% lighter and 30% more rigid than previous models. This reduction in weight is achieved without compromising the vehicle’s structural integrity, leading to improved fuel efficiency and performance.

Enhanced Safety Features

The SKYACTIV® platform incorporates ultra-high tensile-strength steel in critical areas, making the body both lighter and stronger. This design not only enhances the vehicle’s safety but also contributes to its overall stability and handling.

Improved Handling

The SKYACTIV®-CHASSIS features advanced front and rear suspension mechanisms and an electric power steering system. These innovations result in a 14% reduction in weight, which significantly enhances the vehicle’s efficiency and handling. The chassis achieves nimbleness at low speeds and stability at high speeds, providing a superior driving experience.

Environmental Benefits of Skyactiv Technology
