Because three-cylinder engines are not only lightweight but also very powerful, and their fuel consumption is much lower than that of four-cylinder or six-cylinder engines. Overview: Three-cylinder cars refer to vehicles equipped with three-cylinder engines, which offer better fuel economy and lower exhaust emissions. Features: The advantages of three-cylinder cars include a lighter and more compact engine. Compared to a four-cylinder engine, a three-cylinder engine has one less cylinder, one less piston, one less connecting rod, one less set of valves, one less spark plug, one less ignition coil, one less fuel injector, one less intake manifold, and one less exhaust manifold. The lighter weight results in better fuel economy and lower exhaust emissions.

Will stepping on the accelerator during Subject 2 result in failure?

Currently, there are no regulations stating that stepping on the accelerator during the Subject 2 exam is prohibited, so it will not result in point deductions. However, it is still best to avoid stepping on the accelerator. Here are the detailed reasons: There are currently no regulations prohibiting the use of the accelerator during the Subject 2 exam, and the exercises in Subject 2 do not require the use of the accelerator. Therefore, during regular practice sessions, the instructor's vehicle typically has the accelerator locked, preventing students from stepping on it. Additionally, as beginners who have just started learning to drive, students are not yet proficient in controlling the depth and pressure of the accelerator, which is why Subject 2 does not involve stepping on the accelerator.

Why is there a shortage of automotive chips?

The shortage of automotive chips is mainly attributed to three factors: technological evolution, insufficient production capacity, and supply-demand imbalance. Since the COVID-19 pandemic swept across the globe, the economies and production capabilities of major countries have been severely impacted. The global production of automotive chips is predominantly concentrated in Europe and America, regions that were heavily affected by the pandemic, leading to a natural shortage in the supply of automotive chips. Additionally, technological evolution and supply-demand imbalance also contribute to the shortage. Technological Evolution: Currently, global chip foundries are primarily focusing on 12-inch wafers, which has restricted the production capacity of 8-inch wafers. Automotive chips do not require high dimensional specifications, making 8-inch wafers ideal for their production. Insufficient Production Capacity: The automotive chip market is dominated by European and American manufacturers. During the pandemic, the production capacity of these manufacturers was severely affected, leading to tight supply of automotive chips. Supply-Demand Imbalance: The chip industry is characterized by a very typical cyclical nature. Therefore, during the pandemic when global automotive sales were sluggish, manufacturers of automotive chips were hesitant to expand production. However, they did not anticipate the rapid recovery of the Chinese market, which led to a significant increase in chip demand, resulting in a supply-demand imbalance in the market.

Is It Dangerous to Continue Driving with a Damaged Steering Gear?

Continuing to drive with a damaged steering gear is dangerous. The steering gear is the most critical component for the steering function of a car and an essential guarantee for driving safety. If the steering gear malfunctions, you will lose control of the direction, leading to hazardous situations. Common issues with steering gear noise include lack of lubrication in the steering column, which increases friction—ensure the steering column is well-lubricated; insufficient power steering fluid—promptly top it up; problems with the universal joint—regularly inspect and replace it as needed; aging or hardened rubber bushings in the suspension stabilizer bar links—replace them promptly; damaged plain bearings—inspect and replace them periodically. Precautions for using the steering gear include avoiding turning the steering wheel while the car is stationary—try to steer only when the vehicle is moving; after parking, return the steering wheel to the neutral position to prevent unnecessary stress on the suspension system and tires; when making a U-turn, avoid turning the steering wheel to its extreme limit.

Is There Any Consideration for the Car Delivery Date?

Purchasing a new car is a significant life event, and many people have various considerations, leading them to be particular about the timing. Taboos regarding the car delivery time: Personal taboo dates: Avoid dates where the five elements conflict with the owner's five elements; avoid days that clash with the owner's zodiac sign; avoid selecting the owner's birthday for car delivery; avoid personal special taboo dates for car delivery. Avoid the 'Sui Po' day for car delivery: The 'Sui Po' day is a date that conflicts with the current year's Tai Sui, and it is usually marked on the lunar calendar as 'Day of Sui Po, unfavorable for all matters.' Avoid inauspicious dates for car delivery: Generally, it is also not advisable to pick up the car on inauspicious dates such as 'Huang Sha' day, 'Wang Wang' day, 'Sang Che Sha' day, etc.

What does DPF exceeding the limit mean?

DPF exceeding the limit refers to emissions exceeding the standard. DPF (Diesel Particulate Filter) is a device installed in the exhaust system of diesel vehicles to reduce particulate matter in the exhaust through filtration. Here is relevant information: Function: The diesel particulate filter can effectively reduce particulate emissions. It first captures particulate matter in the exhaust gas and then oxidizes the captured particles to regenerate the particulate filter. The so-called filter regeneration means that during long-term operation of the DPF, the gradual accumulation of particulate matter in the filter will cause an increase in engine backpressure, leading to a decline in engine performance. Working process: The diesel particulate filter (DPF) captures particles through a hybrid filtration device combining surface and internal mechanisms, such as diffusion deposition, inertial deposition, or linear interception.
