Exclusive - Fresh New Mazda Technology from Europe

[shakespeare]

Our friends at Mazda Australia have provided some information on the fresh new technology direct from Europe, see below for more information.

SKY-G
• Diesel-level efficiency
• B-segment fuel economy from C-segment while maximizing actual-use torque (-15 % fuel economy and +15% torque)
• Smooth and linear response with naturally aspirated engine, without expensive external devices (turbo, compressor)
• Efficient calibration that works for all engines due to their common combustion character. Meaning the series of engines could be deployed promptly across the entire all vehicle range.

SKY-D
• Provide the same fuel economy as a two-class-smaller GE vehicle (20% improvement from current DE)
• Comply with Europe Stage6, USA Tier2 Bin5 and Japan post new long term standards without expensive NOx after treatment
• Be more affordable than HEV with Stage6 compliance at lower cost than current Stage5 engine
• Provide smooth and linear response (Maximum speed: 5200rpm)


SKY-DRIVE
• Incorporate advantages of all types of transmissions: DCT, CVT and torque converted AT
• Contribute to improvement in fuel economy with 4 - 7%
• Provide manual-transmission-like direct feeling and quick shifting feel
• Have a smooth and powerful startup performance and smooth shifting
• Lightweight and compact


Next generation manual transmission
• Have a sporty and crisp MX-5-like shift feel
• Lightweight and compact


Chassis (Suspension / Steering)
• Balance linear and accurate steering/handling with stability and provide comfortable and premium ride.

Chassis (Brake)
• Achieve easy-to-control and effective brake performance

Body
• Achieve best crash safety performance of body i.e. in each market
• Develop the most lightweight body
• Provide high-level, kinematical performance-supporting stiffness of the body


SKY-G
Key technical points
• Realization of both high low-end torque and diesel like fuel economy with high compression ratio of 14:1
•
Technical highlights
Knocking avoidance by lowering fuel air mixture temperature
• Scavenge hot residual gas, cooling mixture temperature by injected fuel latent heat
• Adopted technology = 4-2-1 Exhaust system, multi-hole injectors
• Catalyst warm-up technology for 4-2-1 exhaust by fuel injection and in-cylinder flow (meet Euro Stage6, US PZEV)
• Adopted technology = Direct injection system
Stratified mixture formation after engine start (realizing ultra retarded combustion for exhaust gas temperature increase)
Engineering efficiency innovation
• Commonization of combustion and air intake behavior through CAE, computer aided engineering

SKY-D
Key technical points
• High expansion ratio combustion utilizing low compression ratio, and European Stage6, USA Tier2 Bin5 and Japan post new long term standard compliance without expensive NOx after treatment
Technical highlights
Technology will avoid miss firing during cold engine start and warm up conditions with compression ratio 14:1 diesel engine.
• Spatial fuel distribution control technology, and mixture temperature increasing technology by recirculating hot exhaust gas
• Adopted technology = Precise injection control by piezo injector, exhaust variable valve lift control
Manufacturing efficiency innovation
• Manufacturing line shared with gasoline engines  

SKY-Drive
Key technical points
• Realization of both lock-up area expansion and NVH performance
Technical highlights
Vibration damping control and precise oil pressure control
• Input torque variation damping and transfer function/sensitivity characteristics improvement
• Adopted technology = Small torus (vane), multiplate clutch, torque converter with low rigidity damper, engine / transmission vibration cooperative control
• Precise oil pressure control
• Adopted technology = Mechatronic module, direct linear solenoid

Chassis (Suspension / Steering)
Key technical points
• Achievement of both feeling of lightness in medium/low and high-speed areas stability and ride
Technical highlights
Yaw gain and steering response according to speed
• Kinematical and compliance characteristics improvement, steering gear ratio change to high speed, front caster angle enlargement, electric power assisted steering control improvement
Body-input reduction
• Kinematical and compliance characteristics improvement and damper lever ratio enlargement


Chassis (Brake)
Key technical points
• Realization of high-level balancing of effectiveness with stiffness feel, and shortening of brake stopping distance
Technical highlights
Achievement of both high frictional force and low vibratory force, weight reduction and braking heat performance
Achievement of both lower rolling resistance tires and shorter brake stopping distance

Interesting... Nothing there a bout a Forced Induction Petrol Engine. Lending some weight to the possibility tha the next gen MPS could see a high compression Turbo Diesel.

sounds good. Lets see it in action
