Acoustic Control Induction System

Acoustic Control Induction System, or ACIS, is an implementation of a Variable Length Intake Manifold system designed by Toyota.
Simply put, the ACIS system uses a single intake air control valve located in the intake to vary the length of the intake tract in order to optimize power and torque, as well as provide better fuel efficiency and reduce intake "roar"..
The engine control unit (ECU) controls the position of one or more air control valves based on input signals from throttle angle and engine RPM. The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run. By de-energizing the VSV, vacuum to the actuator is blocked and trapped vacuum is bled off of the actuator diaphragm. Toyota ACIS is an On/Off system. The valve (or valves in newer models with multiple valves to create more than 2 lengths) is either fully opened or fully closed. An example of early single-valve ACIS programming would be the 3.0L 3VZ-FE engine. The ECU actuates the VSV to close the valve when the throttle position is 60% or greater and engine speed is 3,900 RPM or greater.

HUMMER H3

The Hummer H3 was a crossover SUV/Sport Utility Truck from General Motors' Hummer division introduced in 2005 based on the GMT355 underpinning the Chevrolet Colorado and GMC Canyon compact pickup trucks. Produced at GM's Shreveport, Louisiana factory and the Port Elizabeth plant in South Africa the H3 was the smallest among the Hummer models, and the first to be built by GM. It was available either as a traditional midsize SUV or as a midsize pickup known as the H3T.

Electric bicycle

An electric bicycle is a conventional bicycle that has been fitted with an electric motor. Converting an existing bicycle by retrofitting it with a "conversion kit" is the simplest and least expensive electric vehicle conversion option. Most often electric bicycles or "e-bikes" are powered by rechargeable batteries however some experimental electric bicycles run directly on or recharge their batteries via solar panels, fuel cells, gas generators or other alternative energy sources. Some experimenters have even used super capacitors to store energy. Using an on-board generator may impact the legal jurisdictional definition of an electric bicycle. A few types of electric bicycles are able to re-capture a small amount of energy from braking and can re-charge the batteries while braking or traveling down hills (regenerative braking).

Some electric bikes have features where the motor can move the bicycle by itself (immediate start) if the rider chooses not to pedal with a button or throttle controller, while others require the rider to pedal at all times (pedal assist). This latter type may in some jurisdictions allow the vehicle to be used on bicycle trails that otherwise prohibit motorized vehicles of any kind (See motorized bicycle).
Many battery technologies are available for powering electric bikes. The most common and least expensive battery technology is sealed lead acid but LiFePO4 is fast becoming the battery of choice for the e-bike.
Converting one's bike to electric with a conversion kit is an easy and affordable solution for most people interested in learning more about electric vehicle conversion. E-Bikes are the cleanest, most affordable and most energy efficient form of transportation on the planet.
There may be some problems with the warranty however on the original bicycle being converted, if an electric bike conversion kit is added.

volkswagen beetle

The Volkswagen New Beetle is a small family car, introduced by Volkswagen in 1998, drawing heavy inspiration from the exterior design of the original Beetle. Unlike the original Beetle, the New Beetle has its engine in the front driving the front wheels and luggage storage in the rear. In May 2010, Volkswagen announced that production of the current body of the New Beetle will cease in 2011. A redesigned model will replace it.

At the 1994 North American International Auto Show, Volkswagen unveiled the Concept One, a "retro"-themed concept car with a resemblance to the original Volkswagen Beetle. Designed by J Mays and Freeman Thomas at the company's California design studio, the concept car was based on the platform of the Volkswagen Polo.

Porsche Cayman

Latest Vaian Porsche Cayman R 2011 from two seats to bring the concept car from Germany. Cayman R 2011 has a new chassis that is lighter, only about 120 pounds and a few other tweaks. Porsche vehicles are also bringing new features to the interior Cayman R 2011.

Cayman R 2011 has new features such as Alcantara and leather upholstery, sport seats, door handles and console rope dicata key color for the exterior. This vehicle suspension parts also increases to be lower, if viewed from the front wheels and rear axle distance is 20 cm lower than the Cayman S. series Motivation comes from Porsche’s 4.3-liter flat-six, bumped slightly to 330 horsepower, while the transmission options including Porsche MDD excellent automatic gearbox six-speed manual or traditional. According to carmakers, the Cayman 2855-pound R will hit 62 miles per hour in less than five seconds and top out at 175 mph. Find R Cayman at the dealer to charge $ 66,000 before the end of the year. Follow the jump for the official press release from Porsche.

Porsche would reveal a new Cayman at the LA Machine Pretence – Porsche Cayman R, is 121 lb light and has ten more horses than the Cayman S. It’s the perfect Crocodilian for those who suppose it requisite upright a hint solon power and a ghost fewer unit. The refer pays extortion to the low Porsche with the “R” determination, the 911 R of 1967. It give go on marketing in Feb 2011, at a damage of $66,300.

With the new Cayman R, Porsche also focused on reducing the car’s unit. For that the set misused only lightweight components and renounced to any suitability equipment. There is also a new set 19 progress feathery wheels. The lead is a numerate weight of 2855 lb and a power-to-weight apportion of 8.6 lb per h.p..

The Porsche Cayman R is supercharged by a tuned-up 3.4 liter six-cylinder engine, develops an spectacular 330 horsepower. In the classical plan it transmits its noesis to the place wheels via a six-speed exercise casing. The the velocity from 0 to 60 mph, now prefabricated in 4.9 seconds (or 4,7 seconds with the facultative Athlete Chrono packages) and the top quicken of 175 mph with practice case, or 174 mph with PDK.

dodge viper

The Dodge Viper is a V10-powered sports car made by the Dodge division of Chrysler. Production of the two seat sports car began at New Mack Assembly in 1991 and moved to its current home at Conner Avenue Assembly in October 1995. The car, and numerous variations, has made many appearances in TV shows, video games, movies, and music videos. The replacement for the fourth generation Dodge Viper formed the basis for the Mercedes-Benz SLS AMG. Although Chrysler considered ending production because of financial problems, chief executive Sergio Marchionne announced and showed on September 14, 2010 a redesign of the Viper for 2012.
The Viper was conceived as a historical take on the classic American sports car. The iconic AC Cobra was a source of inspiration, and the final version of the Viper bears this out with its powerful engine, minimalist straightforward design, muscular and aggressive styling, and high performances. Some saw claims to kinship with the Cobra as a marketing exercise, ignoring that Carroll Shelby was heavily involved in the initial design of the Viper, and subsequent design of the Viper GTS coupe. Notably, the later (1996 through 2002) Viper GTS coupe took a few design cues from the Pete Brock designed Shelby Cobra Daytona. Though the proportions seem similar at first glance, the designs are quite unique. Carroll Shelby was key in the development of the RT/10 as well as having a hand in the development of the GTS model.
The Viper was initially conceived in late 1988 at Chrysler's Advanced Design Studios. The following February, Chrysler president Bob Lutz suggested to Tom Gale at Chrysler Design that the company should consider producing a modern Cobra, and a clay model was presented to Lutz a few months later. Produced in sheet metal by Metalcrafters, the car appeared as a concept at the North American International Auto Show in 1989. Public reaction was so enthusiastic, that chief engineer Roy Sjoberg was directed to develop it as a standard production vehicle.
Sjoberg selected 85 engineers to be "Team Viper," with development beginning in March 1989. The team asked the then-Chrysler subsidiary Lamborghini to cast some prototype aluminum blocks based on Dodge's V10 truck engine[citation needed] for sports car use in May. The production body was completed in the fall, with a chassis prototype running in December. Though a V8 was first used in the test mule, the V10, which the production car was meant to use, was ready in February 1990.
Official approval from Chrysler chairman Lee Iacocca came in May 1990. One year later, Carroll Shelby piloted a pre-production car as the pace vehicle in the Indianapolis 500 race. In November 1991, the car was released to reviewers with first retail shipments beginning in January 1992.
