What does tfsi mean?

tfsi stands for Fuel Stratified Injection technology, which is applied in turbocharged engines. A turbocharger is an air compressor that serves to enhance the engine's output power. Without altering the engine's cylinder capacity, it achieves this by solely increasing the compression ratio of the air entering the cylinders. The working principle of a turbocharger is as follows: it utilizes the exhaust gases expelled from the engine's exhaust outlet as the driving force to propel the turbine wheel inside the turbine housing. Simultaneously, the turbine wheel is directly connected to the compressor wheel in the compressor housing. One end of the compressor housing is linked to the air filter, while the other end compresses the air drawn in from the air filter into the engine's cylinders, thereby increasing the amount of air inside the engine.

What Causes Low Battery Power?

The reasons for low battery power are: 1. Insufficient power generation from the alternator; 2. Battery aging or damage, resulting in insufficient charge retention; 3. Low rated capacity of the battery; 4. Vehicle has electrical leakage or excessive standby current; 5. Using electronic devices while the vehicle is parked; 6. Frequent short-distance driving. The battery charging method is: 1. Turn off the engine and remove the battery; 2. Open the vent caps on the battery; 3. Attach the red clamp of the dedicated charger to the battery's positive terminal marked with a plus sign, and the black clamp to the negative terminal marked with a minus sign; 4. Adjust to the 2nd gear and select 12-volt power supply; 5. Plug in the charger, turn on the switch, and start charging.

What is the fuel tank capacity of the CS55?

CS55 is equipped with a 1.5L 156 horsepower engine and comes in eight variants, all with a fuel tank capacity of 58L. This data is announced by the automobile manufacturer, and owners who have purchased the Changan CS55 can also check it on the vehicle's configuration sheet. The Toyota CHR uses 92-octane fuel. Among its models, the 1.5T automatic Xuanzhi, Xuan Cool, Xuandong, Xuans, Xuancai, and manual Xuans models all have a fuel consumption of 6.6L/100km, allowing a full tank to cover a distance of 879km. The 1.5T manual Xuanmu and Xuandong models have a fuel consumption of 6.5L/100km, with a full tank capable of covering 892km. During daily driving, it is essential to monitor the remaining fuel in the tank. This is typically observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.
