Automobile Manufacture Profession Application High-tech Following ten high-tech certainly are not the nowadays automobileindustry high-tech complete, but they will be basic may represent theworld automobile future 20 years development situation. Therefore,makes a comprehensive understanding to these high-tech also to be ableto be able dynamically to grasp the world automobile for you thescience and technology to have the help. 1st, V10 engine Development company: BMW Application vehicle type: Valuable horse M5 The new style valuable horse M5 has provided V 10 cylindersnew engines, the V10 engine displacement is 5.0L, the peak poweroutput is 378kW (507bhp), the maximum torque is 520Nm. The V10 engineuses the nature inspiration, enters the red area limit from 8250rpm(engine speed boundary). V 8 cylinders engines provides which withprevious generation M5 compare, the V10 output increased 25%,guaranteed the 1L displacement to surpass 100bhp the output, thisenable M5 to have the vehicle race unusual performance。 The V10 engine in order to balance the crank the revolution, established the air cylinder 90°; In order to guarantee bearsexplodes the cylinder, high revolves and the vibration rigidity, itscrank case has used the rudder core skeleton structure. Supports thecrank the bearing to have 6, this company uses the support structureon V engine, still was for the first time. V10 engine each aircylinder has 4 valves, provides bi-VANOS (invariable valve structure). This engine necessary use gear box is 7 fast automatic MTSMG. The characteristic reduced the speed change time, compared withbefore SMG, the speed change time reduced about 20%. Moreover, it alsoestablished the coordinate movement pattern 11 kinds to select andmatch the way. V 10 cylinders engines are same with other specialengines, is located the German Munich in this company the factory useflexible production line production　　 After 2nd, hangs the curving car axle WATTS connecting rod Development company: Pl
