Volkswagen develops a new system that combines mechanical and turbocharged
Known as SuperTurbo, the system is a combination of turbocharger specialist Eaton that eliminates turbo lag while improving engine power and fuel efficiency over existing conventional turbocharged engines. 15% to 20%. The model equipped with this system will be available at the Frankfurt Motor Show next month.
The system utilizes a supercharger to operate at low engine speeds to increase torque output at low speeds, while another turbocharger provides additional power while the engine is running at medium speed once the turbine reaches sufficient When the speed provides powerful power, a clutch will separate the supercharger from the engine and close the intake valve to avoid the use of a supercharger.
Volkswagen plans to use the system extensively, first on the 06 golf with a 1.4-liter direct-injection gasoline engine, and then promote it to other models. The engine is available in two different versions: one with an output of 140 hp and a peak torque of 184 lb-ft, while the other with a higher performance has a maximum power of 170 hp and a peak torque of 199 lb. In comparison, Volkswagen's current 2.0-liter four-cylinder engine has a maximum power of 150 hp / 148 lb-ft. In addition, the more powerful 1.6-liter and 2.0-liter engines that Volkswagen is developing will also be equipped with this booster system, which will have 195 horsepower and 240 horsepower respectively.
The unit will first be equipped on models sold in the European market to compete with those equipped with turbo diesel engines. This system may also be equipped on diesel vehicles, but in the future North American market depends on the price of oil and local demand for high-power engines.
The wolf speaks a new language: Volkswagen combines two turbochargers to make full use of the advantages of both, that is, to increase power and achieve fuel-saving purposes. The small displacement car can still have powerful power and low fuel consumption, which is really good for both.
The bumpers are designed to protect the hood, trunk, grill, fuel, exhaust and cooling system. A Bumper is a shield that is usually made of steel, aluminum, rubber or plastic. It absorbs shocks from car accidents. The standard requires protection in the region 16 to 20 inches above the road surface.Bumpers protect important equipment on automobiles such as headlights, taillights, hood and exhaust and cooling systems. These components are all expensive to replace, and a bumper can eliminate or reduce the costs of repairing them.These traits allow a bumper to line up flush with an opposing bumper in order to absorb any impact and maintain stability.
