Honda’s Insight is back. Introduced as North America’s firstgas-electric hybrid vehicle in 1999, the Insight was an aluminum-bodiedtwo-seat economy car that offered great fuel economy and performance inthe same package. Now the Insight name has been applied to a new 2010model with more advanced technology and room for five passengers.
The original Insight used Honda’s IMA (Integrated Motor Assist)technology which placed a thin but powerful electric motor between thegas engine and the transmission. This motor would assist the gas engineas needed to improve fuel economy and performance. Several Civic andAccord models have used succeeding generations of the IMA technologyand the new Insight will incorporate the fifth generation of Honda’sIMA hybrid powertrain.
The IMA powertrain is really an integrated three part system: the1.3-litre three-cylinder gasoline engine uses low-friction featuressuch as offset cylinder bores, low tension rings and low frictionpistons to reduce parasitic drag. The single overhead cam engineutilizes two valves per cylinder with dual-stage rocker arms that arecontrolled by the engine computer to change valve lift and timing formaximum economy and performance. This i-VTEC valve control systemallows the engine operation on only some cylinders, and can alsomaximize electrical regenerative braking by reducing the gasolineengine braking during deceleration.



The electric motor located between the engine and the transmissioncan put out 13 horsepower at 1500 rpm and 58 lb-ft. of torque at 1000rpm. Combined with the gasoline engine, maximum power is 98 hp and 123ft lbs of torque. The ultra-thin brushless DC electric motor will startthe gas engine quickly during AutoStop events (during a stop at atraffic light) and can assist in accelerating the car away from a stop.It can also assist during steady state cruising situations and is ableto propel the car by electric power only in the mid- 40 km/h range ifdriving load conditions are light.
During deceleration, the IMA unit becomes a generator, while thecomputer operates the gasoline engine valvetrain to minimize enginebraking. Regenerative braking from the electric motor is then used torecharge the battery module.
Honda refers to the IMA power source as the Intelligent Power Unit(IPU). This module contains the battery assembly, the electric motorcontrol unit and a compact cooling system. The IPU is located below therear cargo area, allowing for a 60/40 split folding rear seat andmaximum cargo capacity.
The battery consists of 84 individual Nickel Metal Hydride “D” cellsconfigured into seven modules with a total output voltage of 100.8volts and a capacity of 5.7 amp-hours. Compared to the 4th generationbattery in the 2006 Civic, this battery unit is 19 per cent smaller and28 per cent lighter but has a 30 percent higher power output.


The CVT (Continuously Variable Transmission) unit is the third partof the hybrid powertrain. By keeping the gear ratios at their optimum,the CVT enables both the gasoline engine and the electric motor tooperate at peak efficiency. It can also be quickly controlled to othergear ratios during deceleration for the greatest regenerative braking.
The gas engine, electric motor and CVT all work together to providethe best performance and economy but there is still another variable –the driver.
Honda helps the driver operate the vehicle for maximum economy withtheir Ecological Drive Assist System (Eco Assist). By pressing the ECONbutton on the left side of the dash, the computer programming ischanged to enhance the efficiency of several vehicle systems, includingthrottle control, transmission operation, air conditioning, cruisecontrol and idle stop time. It also changes the colour of thespeedometer background to notify the driver how they are driving. Greenis good, while less efficient driving causes the display to change toblue-green and aggressive driving will change it to blue.
Finally, the driver can monitor the results on the dashmulti-information display. Fuel economy, driving efficiency and brakingefficiency are shown. There is also a lifetime performance display andECO Guide, which rewards efficient drivers by displaying a number of“leaves” on the display. Five leaves are the best reward. With thedriver now more aware of vehicle economy and how driving style affectsit, fuel economy is sure to improve even more.

本田的Insight回來。 作為北美地區第一批油電混合動力汽車在1999年,敏銳的洞察力是一個鋁健全兩個席位經濟提供了極大的汽車燃油經濟性和性能在同一個封裝。現在的洞察力名稱已被應用到一個新的模型, 2010年更先進的技術和房間的5名乘客。

使用原來的洞察本田的IMA (綜合電機輔助)技術,該技術將一個薄,但功能強大的電機之間的汽油發動機和變速箱。這將有助於汽車汽油發動機的需要,以改善燃油經濟性和性能。一些市民和Accord車型使用後世的IMA的技術和新的認識將納入第五代本田的IMA混合動力。

該IMA的動力實際上是一個綜合的三個部分系統: 1.3升3缸汽油發動機使用低摩擦特性,如抵消缸孔,低張力環和低摩擦活塞,以減少寄生阻力。單凸輪軸發動機採用每缸兩氣門雙階段搖桿武器控制的發動機電腦改變氣門升程和時間最長的經濟和性能。 這是我- VTEC氣門控制系統可在發動機運行的只有一些氣瓶,也可以最大限度地提高電力再生制動,減少在汽油發動機制動減速。

電動機之間的發動機和變速器可以把13匹馬力在1500轉和58磅英尺.扭矩在1000轉。結合汽油發動機,最大功率為98馬力和一二三英尺磅的扭矩。超薄無刷直流電動機將開始在汽油發動機迅速AutoStop事件(在停在交通燈) ,可以協助加快車離站。 它也可以協助巡航在穩態情況,並能推動汽車的電力只有在中期四十零公里每小時範圍如果駕駛輕負載條件下。

的單位成為一個發電機,而計算機的運行汽油發動機配氣,盡量減少發動機制動。再生制動系統的電動馬達,然後使用可充電電池模塊。

本田指的IMA電源的智能動力單元(議會聯盟) 。此模塊包含電池大會,電機控制單元和緊湊的冷卻系統。議會聯盟是位於下方的後方貨運領域,允許分裂60/40的折疊後座和最大的貨物的能力。

電池包括84個人的鎳金屬氫化物的“ D ”細胞配置分為七個單元,總輸出電壓為100.8伏特和能力五點七安培小時。相比,第四代電池在2006年公民,本電池組是百分之十九小和更輕的百分之二十八,但有百分之三十較高的輸出功率。


該電容式電壓互感器(無級變速器)單位是第三部分的混合動力。.通過保持其傳動比最佳,該無級變速器能使汽油發動機和電動機運行的峰值效率.它也可以迅速地控制其他減速時傳動比為最大的再生制動。

天然氣發動機,電動機和CVT共同努力,提供最佳的性能和經濟,但仍然有另一個變數-驅動程序。

本田幫助司機操作車輛的最大的經濟體系,其生態驅動輔助系統(生態協助) 。按經濟學上的按鈕左側的破折號,計算機編程的變化,以提高效率的若干車輛系統,包括節氣門控制,傳輸作業,空調,巡航控制和閒置的停止時間。它也改變了顏色的速度背景通知司機如何駕駛。 綠色是很好的,而效率較低的原因顯示駕駛變更為藍綠色並積極推動將其更改為藍色。

最後,司機可以監測結果的破折號多信息顯示。燃油經濟性,駕駛效率和制動效率的表現。還有一個一生業績顯示,經合組織指南,其中獎勵高效率的驅動程序顯示了一些“葉子”在顯示器上。五葉是最好的獎賞。 與司機現在更清楚地了解車輛的經濟和如何影響它的駕駛風格,燃油經濟性肯定會提高得更多。
