Does the New Santana Need to Have Its Ignition Timing Angle Installed?

From the moment of ignition until the piston reaches the top dead center of compression, the angle through which the crankshaft rotates during this period is called the ignition timing angle. Installation is not required, but adjustment may sometimes be necessary. Adjusting the ignition timing angle: Remove the secondary chamber vacuum hose from the vacuum advance compensation device and block the two ports connected to the hose. Then, let the engine idle, and use a timing light to check the ignition timing angle. Verifying the ignition timing angle: Start the engine and repeatedly press the accelerator pedal. If the engine feels powerful and there are no abnormal knocking sounds, it indicates that the ignition timing angle is appropriate. A timing light can also be used to confirm the ignition timing angle. As the engine speed increases, the timing mark will move in the direction of increasing ignition timing angle.

Is Audi a Joint Venture or Domestic Brand?

Audi only offers imported vehicles and joint venture models, with no purely domestic variants. Domestic vehicles refer to models produced by China's independent automotive brands. Joint venture vehicles of German brands like Audi are manufactured domestically, with Audi models in China being produced by FAW. Audi maintains globally unified quality inspection standards, utilizing fully automated triangular coordinate laser measuring instruments that can detect any production deviations during quality checks. The Audi A6L model, produced by FAW, features the FAW Audi emblem on its rear, which is absent on imported models. The 'L' suffix in the model designation indicates an extended wheelbase, catering to Chinese consumers' preference for longer vehicles, explaining why imported Audi models often appear slightly shorter than their FAW-produced counterparts.
