Le l'hanno i Jap, in USA, in UK, e a noi no? Ecco che cosa vuol dire avere accesso: la possibilità di comprarla senza andare all'estero. | |

Guarda che cosa mi è arrivato per caso ieri sera: http://world.honda.com/news/2005/4050705_b.html AutomobileJuly 5, 2005 Honda Announces Development of New Honda Hybrid System Featuring 3-Stage i-VTEC + IMA -New Civic Hybrid powerplant scheduled for fall 2005 introduction- Watch The Movie TOKYO, Japan, July 5, 2005 - Honda Motor Co., Ltd. announced that it has developed a New Honda Hybrid System, which features a 3-stage i-VTEC engine that employs Honda's intelligent VTEC (Variable Valve Timing and Lift Electronic Control) system to provide three stages of valve timing (low-rpm, high-rpm, and cylinder idle mode), combined with Honda's IMA (Integrated Motor Assist) system that has been made significantly more compact and efficient. The New Honda Hybrid System will be introduced in the all-new Civic Hybrid, to be launched this fall. New Honda Hybrid System (3-stage i-VTEC + IMA) cut-away model The New Honda Hybrid System employs intelligent engine functions and a more efficient IMA system to achieve an approximate 20% increase in system output over the current system1 and the powerful performance of a 1.8-liter engine while improving fuel economy by 5%2, reducing the system size by 5% and attainting a world-leading level of emissions performance. The system offers significantly improved performance and fuel economy over the current system. 1 Current Civic Hybrid system 2 Compared to current Civic Hybrid when driven in 10-15 mode The 3-stage i-VTEC engine employs three hydraulic pathways to couple and uncouple five rocker arm assemblies, providing three stages of valve control depending on the driving conditions to achieve a combination of responsive driving and fuel economy. During deceleration when the cylinders are idle, combustion in all four cylinders is halted and the cylinders sealed shut, reducing pumping losses caused by engine aspiration for a 10% improvement in recovery of braking energy compared to the current model3. Virtually everything possible has been done to reduce friction as well, including the use of aluminum die-cast pistons, which feature low thermal expansion for less friction under high-temperature conditions, ion-plated piston rings, and plateau honing of the cylinder walls for a smoother surface. 3 Current Civic Hybrid Honda's independently developed electric motor employs coils with high-density windings and high-performance magnets to attain output 1.5 times that of the current model while maintaining the same size. The inverter used to control motor speed-also independently developed and manufactured by Honda-is integrated with the motor's ECU for more precise digital control, contributing to even greater motor efficiency and fuel economy. Battery output has been increased by around 30% over the current model3, while a more compact, custom designed battery storage box offers increased cooling performance and vibration resistance for improved long-term reliability. Also, a dynamic regenerative braking system is employed that hydraulically controls the brakes based on the amount of brake regeneration. This permits maximum braking regeneration along with smooth deceleration that conforms to brake-pedal pressure. The air conditioner features a hybrid compressor that is powered by both the engine and the motor. When the engine is in Idle Stop mode the compressor is powered by the motor; if rapid cooling is required it is powered by the engine and motor combined. When the temperature is stable it runs off the motor alone, for both improved comfort and fuel savings . *All values are based on Honda in-house calculations New Honda Hybrid System Modes of Operation . Vehicle stationary The engine is turned off and fuel consumption is zero. . Startup and acceleration The engine operates in low-speed valve timing mode, with motor assist. . Rapid acceleration The engine operates in high-speed valve timing mode, with motor assist. . Low-speed cruising The valves of all four of the engine's cylinders are closed and combustion halted. The motor alone powers the vehicle. . Gentle acceleration and high-speed cruising The engine operating in low-speed valve timing mode powers the vehicle. . Deceleration The valves of all four of the engine's cylinders are closed and combustion halted. The motor recovers the maximum amount of energy released during deceleration and stores it in the battery.

Questo SI che è l'ibrido parallelo AKA semplice: Al posto del volano c'è un motore elettrico che assiste il motore termico. Puoi notare che è piccolino, rispetto al motore Prius (ca. 4X). Poi su questa versione la Honda, come descrive il communicato stampa, fa i suoi truschini per consumar di meno ma: Sia in frenata, sia in partenza l'IMA trascina con se un peso morto: perdita di potenza in accelerazione e energia in decelerazione: il THS invece ha il termico spento e staccato dalla trasmissione, l'unica resistenza è il suo peso fisico. L'IMA può essere sia manuale che automatico; il cambio ce l'ha, invece al THS è assente; puoi solo esprimere il desiderio di andare avanti o indierto. Per molti, esso è un Pro alla Honda. Per il resto, questa tecnologia è veramente alla portata di tutti, mentre il THS della Toyota richiede un progetto ex-novo. | ||

| C'è qualcosa che mi puzza qua: Performance Engine Max. output (kW [PS]/rpm) 70[95]/6,000 Max. torque (N·m [kg·m]/rpm) 123[12.5]/4,500 Electric motor Max. output (kW [PS]/rpm) 15[20]/2,000 Max. torque (N·m [kg·m]/rpm) 103[10.5]/0~1,160 System Output Max. output (kW [PS]) 70+15[95+20] Max. torque (N·m [kg·m]) 167[17.0] 70KW @ 6000 + 15 @ 2000 non mi da 85KW 123nm @ 4500 + 103 @ 0-1160 mi può dar 167 ma a che giri? La Prius ha 57KW + 52KW = non 102KW ma 80KW @ 85 Km/H in su. (3250 rpm motore elettrico) 400 nm + 105 nm = non 505nm ma 485 a 25 km/h (955 rpm) |
