At present, in terms of the development of new energy vehicles, the battery energy density of pure electric vehicles still cannot reach the level of current internal combustion engine vehicles. Therefore, the development of plug-in hybrid vehicles is an effective means to solve the problem of energy conservation and environmental protection of automobiles. Volkswagen Group has adopted plug-in hybrid power technology as its main route for its future new energy strategy, and Volkswagen CEO Martin Wendern confirmed: "In the next few years, we will use plug-in hybrids to pass all levels. The products are all electrified and help the electric propulsion system to achieve breakthroughs.†Recently, Netcom learned from autoevolution: Volkswagen will launch a new generation of Touran, the new car will be built with the new MQB platform. In addition to the ordinary power, Volkswagen will also introduce a plug-in hybrid. For the mobile model, the power system will use the 1.4TSI engine with the electric motor. The fuel consumption of the new car is only 2L, which is significantly lower than that of the gasoline version. Volkswagen New Energy Strategy Target 2018 Global Largest New Energy Vehicle Manufacturer According to the strategy of the new energy vehicle released by the Volkswagen Group, the new energy vehicle will benefit all of its models, helping to achieve the goal of the world's largest manufacturer of electric vehicles and plug-in hybrids in 2018. At present, the Volkswagen brand has three plug-in hybrid models including XL1, Golf GTE and Passat, which will be unveiled at the Paris Motor Show. The plug-in hybrid version of Touran is expected to become the fourth plug-in hybrid version of Volkswagen. In addition, under the support of the modular platform technology system, Volkswagen Group's two high-end products - Porsche Panamera plug-in hybrid car and Audi A3 e-tron will soon be put into production, after the Audi A6 and Porsche Cayenne and other categories and The series will introduce plug-in hybrid products. Plug-in hybrid version of Touran 100 km fuel consumption is only 2L Although German Volkswagen's main direction in the field of new energy vehicles was not plug-in hybrid power system, the German Volkswagen Group's technology accumulation in this field is not blank. At present, its plug-in hybrid powertrain has a driving range of nearly 30 in pure electric mode. Miles or 50 kilometers; the official total fuel consumption of the 1.4T Touran model with the smallest displacement is 7.4L. With the help of the electric motor, the 1.4T plug-in hybrid version of Touran is expected to drop to 2L, and the fuel consumption will be greatly reduced. Volkswagen replaces Touran with MQB platform As a compact MPV model, the new Volkswagen Touran will be built on the MQB platform. Thanks to the modular platform technology, the new wheelbase will be lengthened and the interior space will be further enhanced. In terms of power, the new car will be equipped with 1.2T, 1.4T, 1.8T engines and plug-in hybrid version. In terms of configuration, the new car will adopt a panoramic sunroof design. As the size of the entire car increases, the rear door of the new car will also increase. It is reported that the Touran model equipped with the internal combustion engine will be unveiled at the Paris Motor Show in October this year, and the plug-in hybrid version is expected to be released next year.
General Introduction
Bit Face Shape Selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The
all-around application bit face specifically for medium hard and homogeneous rock formations.
Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce theload and wear on the gauge buttons, but poor hole deviation control.
4. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Carbide Button Shape Selection:
1. Semi-Ballistic Buttons
2. Ballistic Button
3. Spherical Button
4. Two-step Button
