The 2021 Focus does not feature a four-cylinder engine. It offers a 1.5L three-cylinder and a 1.5T inline three-cylinder engine. Below are the specific drawbacks of three-cylinder engines: 1. Higher costs: Both manufacturing and maintenance costs are higher compared to conventional four-cylinder engines. To achieve high output with small displacement and address the strong vibrations caused by structural asymmetry, many new technologies are required. 2. Higher vibration levels: The unbalanced working state makes it more prone to vibrations. Due to the unequal number of cylinders on each side of the engine, it is more likely to experience shaking during operation, and the engine noise may also be louder. Although balance shaft technology is used to mitigate excessive vibration, the vibration levels are still higher than those of four-cylinder or six-cylinder engines. 3. Lower acceleration performance: Smaller intake volume results in generally weaker starting and acceleration performance. Compared to a four-cylinder engine, having one less cylinder leads to a reduced intake volume, which also limits acceleration performance during the initial stage.

I've driven the 2021 Focus, which has a three-cylinder engine instead of a four-cylinder. Ford equipped this generation with a 1.5-liter EcoBoost three-cylinder engine as its main powertrain. This design focuses on fuel efficiency and environmental friendliness. In my daily city driving, the fuel consumption is around 7 liters per 100km, saving significantly compared to four-cylinder cars. The power is adequate, with quick turbo response during acceleration, though the engine sound feels slightly thin at high speeds. If you're concerned about vibration issues, I recommend paying extra attention to idle conditions during test drives. After six months of ownership, I haven't experienced major problems. Overall, it's very suitable for small families. Using full synthetic oil during maintenance keeps the engine running smoothly. The Focus maintains agile handling, with more precise cornering thanks to its lightweight body. As an economical car, it's a solid choice.

How to Bleed the Brakes of a Geely Emgrand EC7?

Bleeding steps: 1. The air bleeding operation requires two people to cooperate. After replacing or adding brake fluid, the air in the hydraulic pipeline should be bled. 2. One person continuously presses the brake pedal inside the vehicle to raise the pedal position and holds the brake pedal steady without loosening. Meanwhile, the other person underneath the vehicle loosens the bleeder valve to allow the air and brake fluid in the pipeline to be discharged together. 3. When the pedal position drops, immediately tighten the bleeder valve. Repeat this process several times until no air bubbles are discharged from the plastic tube. 4. Tighten the bleeder valve and reinstall the dust cover. Follow the above method to bleed the other wheel cylinders in sequence. During the bleeding process, check and replenish the brake fluid while discharging the air until all the air is completely expelled. 5. Then, add an adequate amount of the specified type of brake fluid to the reservoir.

What are the precursors of timing chain failure in Roewe 350?

Roewe 350 timing chain failure precursors include difficulty in ignition when starting the car in a cold state, or obvious "clicking" abnormal noise from the engine when stepping on the accelerator pedal. If you find that the car has difficulty in ignition or the engine noise is very loud, you should check whether the timing chain of the car is faulty in time. If so, the timing chain should be repaired or replaced in time. The following is the information about the timing chain: 1. The timing chain connects the timing wheel of the engine cylinder head and the crankshaft, and cooperates with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. 2. The timing chain plays a "bridge" role in the engine. Driven by the crankshaft, it transmits kinetic energy to the corresponding parts, and keeps the pistons, valves and other parts in the correct position at different steps, so that the engine can operate normally.

How to Replace the Coolant in Zotye Damai X5 Radiator?

Steps to replace the coolant: 1. Open the engine hood and unscrew the radiator cap. 2. Turn on the drain valve at the bottom of the radiator to drain the existing fluid. After filling the radiator with coolant, start the engine to circulate the coolant in the radiator. 3. Once the operation is complete, inspect the entire radiator and pipelines for any leaks. If leaks are found, drain the coolant again, address the leakage issue, and then restart the process. Below is some information about coolant: 1. Coolant consists of 50% pure water, 40% methanol, and 10% other substances including dyes, corrosion inhibitors, and scale removers. 2. Compared to tap water, ethylene glycol is most notable for its antifreeze properties, whereas water cannot prevent freezing. Additionally, ethylene glycol has a high boiling point, low volatility, moderate viscosity that changes little with temperature, and excellent thermal stability. Therefore, ethylene glycol-based coolant is an ideal cooling solution.

Why does the car shake when starting cold in winter?

Cold start shaking in cars can be attributed to the following reasons: 1. Low temperature: The engine temperature is insufficient, and both fuel and lubricant temperatures are too low. During cold starts, additional fuel injection is required to meet power demands. Larger spark plug gaps result in smaller ignition energy. Poor fuel atomization at low temperatures demands higher ignition energy. Prolonged vehicle use can enlarge spark plug gaps, reducing ignition energy and consequently affecting power performance, leading to shaking. 2. Incorrect air-fuel mixture ratio: Inaccurate fuel-air mixture ratio occurs in both open-loop and closed-loop control systems. In closed-loop controlled vehicles, the oxygen sensor's minimum operating temperature is 370°C. If the exhaust pipe temperature hasn't reached 370°C upon startup, the oxygen sensor won't function. This causes the ECU to make incorrect judgments, leading to errors in controlling the fuel-air mixture and ignition timing through actuators, thereby reducing power output and causing shaking. 3. Faulty coolant temperature sensor: The coolant temperature sensor is crucial for the ECU to determine engine operating conditions. If the engine starts at -10°C but the ECU calculates fuel injection based on 20°C conditions, the insufficient fuel quantity will naturally cause shaking.
