Beiqi Saab d50 engine has the following fatal shortcomings.

The fatal disadvantage of Beiqi Bao Si D50 engine is that the engine noise is too high. But it is also possible that the air intake is blocked or the oil circuit is not smooth, the throttle valve is dirty, the engine belt is loose, the dynamic balance of the wheel or crankshaft flywheel is damaged, or a cylinder of the engine does not inject fuel. These reasons will also cause some cylinders not to do work, resulting in chattering noise and low power. The fatal disadvantage of Beiqi SicBoD50 engine may be insufficient power. The reasons include: 1. SIBCBOD 50 is weak, and when it is below 2000 rpm, it still slowly increases the speed according to its own rhythm; 2. The safety cage reindeer horn body from SAAB is adopted, and the whole front is divided into three energy-absorbing areas to protect the safety of drivers and passengers in the cockpit to the maximum extent. In terms of active safety, SicBoD50 is equipped with ESC body stability control system, and uses the same supplier as Volkswagen, Volvo and other brands to ensure the quality of vehicles in active safety; 3. Among them, emergency braking assistance, body dynamic stability control, automatic curve control, drag torque control and other safety systems are often only available in luxury models. The complete configuration of SICBOD 50 shows that BAIC Group is harsh on the quality of SICBOD 50. The engine of Beiqi SicBoD50 seems to have no fatal shortcomings. Personally, I think it's quite good. The only key disadvantage may be that there are few cars, which is not very advantageous in terms of maintenance convenience and value preservation. However, the comfort and fuel economy of the car are good.
