TD in cars stands for turbocharging. To address the inherent shortcomings of SDI, a turbocharging device is installed on diesel engines, significantly increasing the intake pressure. The compression ratio generally exceeds 10, allowing for high torque even at low RPMs. Moreover, due to more complete combustion, the content of harmful particles in emissions is also reduced. The TDI-equipped direct-injection turbocharged diesel engine technology is highly advanced and incorporates multiple cutting-edge technologies, such as the pump-jet system and adjustable vane turbochargers, which are applied in passenger cars. TDI utilizes high-pressure fuel injection technology with a pump-jet system. This system ensures better mixing of diesel and air, leading to more thorough combustion.

What does a safety technical inspection point deduction violation mean?

Safety technical inspection point deduction violation means that when a motor vehicle is driving on the road, the driver may commit some traffic violations. Once detected by electronic surveillance, the driver will be penalized. Below is the principle of how red-light running is captured by electronic surveillance: 1. First photo: When the front wheels of the vehicle pass over the induction coil on the ground, the electronic device takes the first photo of the vehicle. 2. Second photo: When the rear wheels of the vehicle pass over the induction coil on the ground, the electronic device takes the second photo of the vehicle. 3. Third photo: When the vehicle passes through the intersection and crosses the induction coil on the opposite side of the ground, the electronic device takes the third photo of the vehicle. Below is additional related information: 1. Penalty: Running a red light is a violation of traffic signal rules. Drivers who violate traffic signals at intersections will be subject to corresponding penalties. 2. Red-light running: Generally, if the vehicle stops after crossing the stop line, it will not be penalized.
