The inspiration of the “Earth Dreams Technology” name comes from:
An expression for a set of technologies that takes into account both our need to protect the environment and our desire to provide a joy of driving.
Summary of the key features
1. A gasoline engine that achieves top-of-industry driving performance and fuel efficiency
By enhancing Honda’s original VTEC (Variable Valve Timing and Lift Electronic Control System) technology to thoroughly improve thermal efficiency and minimize friction, a combination of high output and fuel efficiency was achieved. Further, a new engine series employing a new structure for higher expandability was developed.
By gradually renewing the engine starting with the mini-vehicle N BOX, Honda aims to utilize this technology to achieve top-of-industry output and fuel efficiency in every vehicle class within three years.
A wide range of engine classes including the 660cc, 1.3L, 1.5L, 1.8L, 2.0L, 2.4L, and 3.5L classes will feature the technology.
660cc class engine
Employs DOHC and VTC (Variable Timing Control) to improve intake efficiency. Furthermore, the compact combustion chamber also achieves high thermal efficiency.
By shortening the bore pitch compared to the present engine models and reducing the thickness of the cylinder block and camshaft, engine weight is reduced by 15% and fuel efficiency is improved by 10%.
1.3 to 1.5L class engine
Employs VTC, direct injection technology and the Atkinson cycle using the DOHC, VTEC technologies as the base.
Also extensive friction reduction measures are implemented.
1.8 to 2.0L class engine
Employs direct injection technology and the Atkinson cycle using the DOHC, VTEC technologies as the base. Furthermore, implementation of VTC and high-capacity EGR (Exhaust Gas Recirculation) to both the intake and exhaust ports results in significantly reduced friction.
For the 2.0L class hybrid vehicle engines, use of an electric water pump eliminates the need for a belt in the auxiliary device and contributes to a reduction in friction. The VTC system also allows fuel-efficient driving from various driving styles.
2.4L class engine
Based on the DOHC and VTEC technologies, it employs VTC and direct injection technology and implements extensive friction reduction measures.
Standalone engine features include 5% improvements in fuel efficiency and output, as well as a 10% improvement in maximum torque compared to the previous engine.
3.5L class engine
Employs new valve train mechanisms and direct injection technology in the SOHC, VTEC, VMC systems to improve fuel efficiency by over 10% and output by 5%, relative to the present standalone engine model.
2. A compact diesel engine that achieves the world’s lightest body, top-of-class acceleration performance and fuel efficiency
Through optimizing engine rigidity and combustion pressure, an aluminium open deck for the cylinder block was enabled in this top-of-industry lightweight 1.6L class diesel engine.
By downsizing from the present 2.2L engine and extensively reducing mechanical friction in each section, a friction level equivalent to present gasoline engine models was achieved.
Optimization of the thermal management system thanks to improvements in the cooling system reduces CO2 output by over 15%.
Employment of a compact, high-efficiency turbocharger and weight reduction in the reciprocating sliding section results in a sporty and nimble ride.
3. CVT combining the fun of driving and fuel efficiency
Three CVT (Continuously Variable Transmission) structures for mini, compact, and mid-size vehicle classes have been newly developed for a variety of engine sizes.
A reinforced belt is used to realize a structure for which a wide ratio range can be set.
Implementation of analysis technology over the contact behaviour between the belt and pulley, and a high-precision hydraulic control system allows for continual optimization of hydraulic pressure to the pulley under a variety of driving conditions, contributing to improved fuel efficiency.
Use of an electronic oil pump to give an idle stop system with high response contributes significantly to improved usability and fuel efficiency.
“G-Design Shift”, a new coordinated control system for shift transmission, throttle, and hydraulic control responds quickly to driver demands and achieves an exhilarating, sporty drive with superior acceleration.
In the mini-vehicle class, a control mechanism and innovations in axle placement reduce the engine size lengthwise, while a reduction in parts by simplifying the transmission casing structure helps achieve a lightweight and compact body.
For the compact and mid-size classes, in addition to the reductions in size and weight, transmission efficiency was greatly improved by expanding the ratio range to achieve fuel efficiency improvements of 5% and 10% compared to the conventional CVT and comparable 5ATs, respectively.
4. A two-motor hybrid system that achieves top-of-industry efficiency
A two-motor hybrid system featuring top-of-industry efficiency enhancing driving performance and reduced CO2 emissions has been newly developed.
A special lithium-ion battery and charger is employed to enable mounting on plug-in hybrid vehicles.
Mid-sized vehicles equipped with this system are scheduled to begin production, starting with the plug-in hybrid model in 2012 and the hybrid model in 2013.
Three driving modes allowing for top-of-industry efficiency for various driving environments were developed, namely an “EV driving mode” for urban environments, a “hybrid driving mode” using electricity generated by the motor, and an “engine-connected driving mode” where the engine and tyres are mechanically connected during high-speed cruising.
Combination with a high-output 120kW motor allows for superior environmental performance and driving enjoyment.
5. A high-efficiency, high output electric SH-AWD hybrid system that combines superior driving and environmental performance
A new hybrid system, electric SH-AWD, was developed for large-sized vehicles. By combining a 3.5L, V6 engine with this hybrid system, acceleration equivalent to V8 engines, as well as fuel efficiency equal or superior to in-line 4-cylinder engines were achieved.
An electric 4WD system with independent 20kW+ motors on both sides for the rear wheels combines a 7-speed dual clutch transmission system with a built-in 30kW+ high-efficiency motor with the engine.
By mounting a high-performance lithium-ion battery and optimally controlling the front and rear motors, a new hybrid system with high fuel efficiency and output was the result.
By mounting two independent motors in the rear and employing a newly developed bilateral torque adjustable control system, incredibly tight cornering just like driving “on-the-rail” is achievable. With this mechanism, Honda strives to provide a stable ride for various driving environments.
6. A compact, high efficiency electric powertrain for EVs
Thanks to the high efficiency coaxial motor, low-friction gearbox and electric servo brake system, the system gives the highest electrical consumption capability in the world, meeting the required AC consumption rate of 29kWh/100mile (116MPGe) as set forth by the United States.
A traveling distance of 123 miles (LA-4mode: unadjusted) or 210km(JC08 mode) was achieved thanks to the mounting of a high capacity lithium-ion battery.
When using the 240V U.S. electric source, a full charge takes less than 3 hours (from the time a low-charge signal is lit till full charge).
By offering three driving modes (SPORT, NORMAL, ECON), the driver can freely select from a number of options to meet the needs of various driving styles such as power-saving or sporty driving.
