VR6 engine is Volkswagen Group developed, it can be called automotive powertrain wonderful work, special small angle structures can make it take up less space, providing a more structural layout of the entire vehicle extensive feasibility. Through clever design of the intake and exhaust mechanism can make it on the VR6 engine equipped with many modern electronic technology to help smooth breathing engine, through a series of measures to reduce vibrations to reach a more excellent running smoothness, the most important thing is successful VR6 engine and laid a solid foundation for the development of a new generation of compact large displacement engine.
The new VR6 engine Another major change is made from cast iron cylinder replaced by aluminum casting, let the engine heat better. While in the intake system, intake VR6 engine uses plastic material, while with the control device of the variable intake length, can be switched between different intake passage by rotation, for better high and low speed torque output.
For a V-type 6-cylinder engine with an angle of 60 degrees among the most optimized design can be obtained excellent running stability. The 15-degree V-type small-angle VR6 natural break on the golden angle this practice, and engineering personnel through a series of means, particularly by introducing an effective balance shaft to reduce vibration when the engine is running, but the innate structure VR6 the difference or let it not be comparable smooth V6 engine.
