2010 Honda Insight - Technology
The hybrid engine Technology powered with 1.3-liter four-cylinder engine putting out 98 horsepower and 123 lb-ft of torque�the Honda claims is a five-passenger subcompact. It�s mated to a continuously variable transmission (CVT), which provides infinite ratios to keep the engine operating within its most efficient range. On the upscale EX model, Honda offers paddle shifters mounted behind the steering wheel that give the driver the experience of a seven-speed gearbox. A CVT doesn�t actually have gears, so the system uses electronics to direct the transmission to up- or downshift in specific ways when a driver hits the paddle.
The hybrid heart of the system is the fifth generation of Honda�s Integrated Motor Assist (IMA) system. The lightweight, ultra-thin electric motor between the engine and transmission puts out 10 kilowatts (13 horsepower). It is powered by a flat nickel metal hydride battery pack that sits under the rear deck, just behind the gas tank under the rear seat. The battery holds 0.58 kilowatt hours of energy�just slightly less than half the 1.3 kilowatt-hours of the current Toyota Prius pack. The Insight battery is recharged with both spare engine power and regenerative braking, and its accelerator connects to an electronic sensor rather than a cable, also known as �drive-by-wire."
the unique is that Energy for the motor is stored in the usual nickel metal hydride battery pack. Just as Ford has done with the new Fusion hybrid, Honda has updated the Insight's battery, making it smaller and lighter. It contains 7 modules with a dozen D-size cells each. The power output of the modules is 30 percent greater than the Civic and the pack has a total capacity of 580 Wh. That's somewhat less than the 869 Wh of the Civic but it's in keeping with the cost-reduced nature of the Insight. The power electronics, motor ECU and an air cooling system are all integrated with the battery pack. The entire assembly sits below the cargo floor between the rear wheels.see you next
