Die aktuelle 5. Generation des Honda Inspire basiert wieder auf dem US-Accord der 7. Generation. Die дuЯere Form ist praktisch unverдndert.

Unter dem Blech gibt es allerdings viele interessante neue Konzepte, so bietet Honda im Inspire erstmals das Sicherheitspaket CMS in einem Serienfahrzeug an.

CMS ist ein radargestьtztes System, daЯ aktiv Unfдlle verhindern bzw. die Unfallschwere mindern kann. Mehr zu CMS

Als Motorisierung wird in Japan ausschlieЯlich ein 3-Liter-V6 Motor (SOHC, i-VTEC, J30A) mit 250 PS angeboten. Dieser neue Motor soll ьber eine variable Zylindersteuerung verfьgen, den englischen Text dazu habe ich unten angehдngt.

Honda introduces #145;Variable Cylinder Management#146; in V6 3.0-litre I-VTEC engine

Honda Motor Co. Ltd has today introduced a new V6 engine featuring the latest iteration of its i-VTEC (‘intelligent’ VTEC) technology. Through new ‘Variable Cylinder Management’ technology, the V6 3.0-litre i-VTEC engine runs on all six cylinders during acceleration and when high output is required, yet employs only three cylinders during cruising and at low engine loads.

The new engine thus combines the performance of a 3.0-litre V6 engine, while offering fuel economy of 11.6 km/litre #150; comparable to that of a 2.4-litre 4-cylinder engine. This new powertrain will debut in the new Inspire model scheduled for release in Japan 19 June, 2003.

In addition to its low fuel consumption, this V6 3.0-litre i-VTEC engine also significantly reduces exhaust emissions, helping the Inspire meet Japan’s Ministry of Land, Infrastructure, and Transportation requirements for Ultra-Low Emissions and 2010 fuel consumption standards, making it eligible for preferential ‘Green Tax’ treatment. The new engine achieves this by combining high-density catalytic converters located directly below each cylinder head for further improved exhaust gas processing at low engine temperatures with exceptionally fine air/fuel ratio control.

The adoption of a variable intake system, over-sized intake valves, and low back-pressure catalytic converters improves engine respiration efficiency, helping deliver maximum output of 184 kW (250 PS) and maximum torque of 296 Nm. ‘Variable Cylinder Management’ system analyses throttle opening, vehicle speed, engine speed, and gearing to determine that the car is cruising, and then idles the intake and exhaust valves of the three cylinders in the rear cylinder bank. With zero valve lift, the cylinders are sealed, and no fuel is injected. Pumping losses are thus reduced by as much as 65%.

When operating in 3-cylinder mode, engine vibration is reduced by extrapolating vibration from the change in crankshaft rotation speed and sending the information to the ‘active control’ engine mount, which compresses/extends an actuator in same-phase, same-period motion to dampen the engine mount. Similarly, a speaker creates an opposite phase sound or ‘active noise control’, to provide a cancelling effect, for a quieter interior which leaves the driver unaware of changes in cylinder activation.
