Key 4-Cylinder Engine Technologies
The 2.4-liter Accord engine incorporates a host of advanced technologies, highlighted by the adoption of Honda's latest i-VTEC ("intelligent") valve-control system. Developed from technology initially seen in the world of Formula One racing, Honda's original VTEC (Variable valve Timing and lift Electronic Control) system changed the valve lift, timing and duration to suit the engine's running condition.
With continuous phase adjustment of the intake camshaft, i-VTEC adds VTC (Variable Timing Control) to the mix. This latest enhancement, first used on the Acura RSX and also found on the new Honda CR-V and Civic Si engines, provides further improvements to power and torque figures while optimizing overall operating efficiency and minimizing tailpipe emissions. With its greater output, the i-VTEC engine provides the new Accord with better total performance under all types of driving conditions and terrain.
With all-aluminum construction and a 16-valve DOHC design, the new 2.4-liter Accord develops 160 horsepower at 5,500 rpm and 161 lb.-ft. of torque at 4,500 rpm in both LEV and SULEV forms. The combination of VTEC technology with the new VTC provides the engine with even stronger low- and mid-range punch as well as a robust high end. This "intelligent" variation on the basic theme retains the original VTEC hardware that permits the optimization of valve lift and duration as the engine transitions from low-speed to high-speed operation, while adding the ability to continuously vary phasing of the intake cam based on both rpm and load factors. The net result is optimized idle stability, emissions, torque and power.
To further improve its operating efficiency, the engine has been rotated 180 degrees from the previous Accord four. This change permits the catalytic converter to be mounted closer to the exhaust manifold (now on the rear side of the engine), which promotes quicker light-off and thereby helps further reduce cold-start emissions.
2003 Honda Accord
I blame the Americans. No, not for the crisis in the Middle East, not for global warming, not even for fast food. However, I do hold the Americans responsible for making my car ugly. The Honda Civic Hybrid I’ve been lent does many things admirably. It’s a smooth, reasonably well equipped cruiser that is doing its little bit to save the planet by using less fuel than it otherwise would.
LEONBERG-HOFINGEN, Germany — TechArt Automobildesign knows Porsches. It also knows how to make Porsches go the extra mile — even limited-edition, midengine über-Porsches like the Carrera GT.
Lotus Engineering today unveiled the Lotus Exige 265E. Lotus says car is not only probably the world's fastest ethanol automobile, it's also the most powerful road version of the Lotus Exige ever made. The research vehicle weighs just 2,050 pounds, runs on E85 fuel, and has an output of 265 horsepower at 8000 rpm, and peak torque of 184 pound-feet at 5500 rpm. The engine is a modified version of the Exige's existing Toyota powerplant. It will reach 60 mph in just 3.88 seconds, and 100 mph in 9.2 seconds, for a top speed of 158 mph
According to news, the 5.0-liter V8 and electric motor powered car will be able to produce 435 horsepower, reach 60 mph in under 4.0 seconds, and attain top speed beyond 200 mph. The car uses the same powerplant as the Lexus 600h sedan. Due to Toyota’s involvement in F1 racing, engine has been opted for the V8 instead as the race has favorably shifted from V10 to the V8. The car will be unveiled at the 2007 Tokyo Motor Show, which coincides with Japanese Grand Prix, which would be utilizing the car as the official pace car.
The New York Police Department will test drive 10 new Dodge Chargers with V-8 engines to see if the performance sedans can handle the rigors of potholed streets and other anti-driving features of Gotham as well as they can handle 150-mph top speeds, The Associated Press reported.
