The Brabus C-class
The new C-class was only recently been introduced in Germany and already the tuning giant Brabus is set to give the new C-Class some engine upgrades and a modified bodykit with some accessories.
If Mercedes-Benz would like to keep its latest AMG-fettled creation under wraps until the New York Show then it’s entirely a different story for the people in Brabus since they simply just can’t wait to showoff what they did with the new W204 C-Class.
Brabus installs a special crankshaft together with some large pistons which increase the displacement to 4.0 liters. The four-valve cylinder heads were optimized for gas flow and were fitted with special camshafts. The other modification done includes a stainless-steel high-performance exhaust system with metal catalysts together with some newly programmed engine electronics. This conversion has resulted in a maximum power output of 244 kW and a peak torque of 420 Nm at 4200 r/min making the petrol-powered Brabus model capable of sprinting from 0 to 100 km/h in a matter of 5.6 seconds while reaching a top speed of 275 km/h.
Every detail and component of the C-class was not exempted from the attention of the Brabus from the Mercedes ignition coil to the oil burners; etc.---all received the company’s PowerXtra performance kit for the C200 CDI. The first stage of modification D2 (III) includes increasing the power of the 2.0 liter common-rail diesel by 29 kW while the torque soars to 450 Nm.
The Barbus D3 (III) kit increased the power stakes for the C200 CDI by delivering 143 kW while the torque remains the same as the D2 (III). The top of the range C320 CDI gets the D6 (III) kit which revs out an additional 36 kW and boosts the torque to a seismometer-tripping 590 Nm which according to Brabus will allow the C320 CDI to reach 0 to 100 km/h in as short as 6.9 seconds and reaching a top speed of 250 km/h.
The Brabus stainless-steel quad sport exhaust system is offered for all engine variants together with a pair of performance braking systems, custom-made alloys of up to 20 inches in diameter, lowering kits and sway bars.
The Brabus will also offer a striking body kit with time in the wind tunnel that has resulted in a mean looking vent front spoiler, three-piece rear spoiler and a utilitarian rear apron. There are also carbon-fiber mirror covers and an optional LED entrance lights which adds to the attractive styling of the Brabus C-Class.
The remarkable interior features of the Brabus C-Class are handcrafted with Mastik leather upholstery complete with Alcantara accents that is aside from the numerous carbon-fiber and wood trim kits. Accessories that include a sculpted sports steering wheel, aluminum foot pedals and an optimistic 330 km/h speedometer are also available as option.
It must be reassuring on the part of Mercedes-Benz knowing that there are companies like the Brabus that make use of their vehicles to compete head-to-head with the mighty BMW Series.

Engine vibration of construction machinery maintenance and effective method - construction machinery, engines, shock - construction machinery industry
Construction Machinery Engine How to vibration
Engine is the source of power, and our heart as valuable. As the main source of vibration of construction machinery, engine vibration is a technical tender mentioned, due to some effective ways to reduce the vibration. 1, local oscillator control Source of vibration control throughout the design, manufacture and even the use of the whole process, reflected in the balance as to improve engine performance, dynamic performance, Parts Precision machining and assembly. Engine vibration in the form of work is diverse, the main reasons are: the focus of periodic engine moving along the reciprocating parts Cylinder The role of the inertia force from top to bottom, all rotating parts of the centrifugal inertial force, the role of gas pressure caused by the crankshaft rotation cycle of alternating changes. These unbalanced forces and moments are usually the result by changing the engine design parameters to adjust the frequency of the system to avoid structural resonance, improved resonance characteristics, such as the body through modal analysis and finite element method to study the body's natural frequency of vibration mode and so on. Reduce machine vibration source and the first from the design stage to avoid the resonance considered in the overall design of systems engineering thinking through the full application of modern design methods, such as limited source design, reliability design, robust design, optimal design, computer aided design and intelligent system and expert system design. 2, vibration isolation 1, rubber vibration isolation The traditional use of elastic support lower engine vibration, vibration isolation device of simple structure, low cost and reliable performance. Rubber bearing is usually installed in Frame , According to the situation by force into compressive, shear and compression shear and other complex. Compression-type structure is simple, easy to manufacture, widely used and because the natural frequency is high, generally limited to the use of the vertical direction. Low shear vibration frequency, but intensity is not high. Compression and shear composite structure combines the advantages of the first two meet durability and reliability requirements, it is the most widely used at home and abroad. In order to rubber bearing isolation system has good isolation performance parameters form requires the same direction, the spring constant, which would also allow some form of size reduction. String 8 2, spiral steel wire rope isolator
Rope as a damping device with low frequency and large damping of the high-frequency performance of low-stiffness varying parameters, which can effectively reduce body vibration. With the traditional rubber vibration source, compared with anti-oil, anti-corrosion, anti-temperature, high temperature resistance, aging resistance, and the advantages of small size, isolation effect depends on its amplitude is. 3, hydraulic isolation Hydraulic support system is the traditional rubber bearing with hydraulic damping structure composed of one, in the low frequency range can provide larger damping, the value of the engine vibration play a significant role in the rapid decay, the lower the dynamic high frequency stiffness, can be reduced Cab Sound Vibration and dry inside. III engine vibration control of construction machinery Projects sometimes can not avoid resonance, thus, increase the system damping used or vibration absorber to reduce vibration. Vibration absorber is pressing band control using viscoelastic damping material has a high energy loss, when the vibration damping material spread, the material internally generated tension, bending and shearing deformation, which consume large amounts of vibration energy, so vibration attenuation. Vibration damping technology with the main advantage is that without changing the original structure, no additional auxiliary equipment, does not require external Energy , Taking up less space efficient is a promising measure vibration and noise reduction. Zhengzhou "Yutong Heavy Industries" production of new products 955A Wheel Loader Take the lead in the selection of shock absorber vibration absorber using this, the use of new technology to achieve the desired effect of reducing vibration and noise.
