What Causes a Car Not to Move When in Gear?

Failure to shift gears in a car is a comprehensive functional issue involving the clutch, transmission, and drive axle. When diagnosing, first determine the faulty component, and you can start by checking the condition of both wheels. The diagnostic sequence typically proceeds from the drive wheel to the rear axle, then to the driveshaft, and finally to the clutch. If the driveshaft rotates but the car does not move forward, the issue lies with the rear axle. Lift the rear axle and rotate one rear wheel. If the opposite rear wheel turns in the reverse direction while the driveshaft does not follow, it indicates that all the rivets of the differential side gear are sheared. If the opposite rear wheel does not turn, check if the axle shaft is broken. When the car starts in a certain gear and the driveshaft does not rotate, the fault is in the transmission. Remove the transmission cover and check if the transmission shift fork is broken or if the guide block fixing screws are loose. If the above checks are normal, perform a shift test again. If the second shaft does not rotate in a certain gear, the half-round key of the gear is sheared; if the second shaft rotates in direct gear but does not rotate in other gears, the support bearings at both ends of the intermediate shaft may be separated, causing the intermediate shaft to drop. If the driveshaft does not rotate in any gear, the fault lies with the clutch. Check if the clutch is severely slipping, if the spline hub of the driven plate and all the steel plate rivets are sheared, or if the steel plate is broken.

What are the differences between the Sylphy and the Velite 6?

Here are the specific differences between the Sylphy and the Velite 6: 1. Overall Body: The top variant of the Sylphy has a shorter body length compared to the top variant of the Velite 6, but the Sylphy's wheelbase is longer than that of the Velite 6. The latest top variant of the Sylphy measures 4641(mm) in length, 1815(mm) in width, and 1447(mm) in height, with a wheelbase of 2712(mm). The latest top variant of the Velite 6 measures 4683(mm) in length, 1780(mm) in width, and 1465(mm) in height, with a wheelbase of 2700(mm). 2. Powertrain: The Sylphy is equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 135Ps, a maximum power output of 99kW, and a maximum torque of 159N·m, paired with a CVT transmission. The Velite 6 is also equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 122Ps, a maximum power output of 90kW, and a maximum torque of 155N·m, paired with a CVT transmission. In terms of power output, the top variant of the Sylphy is more powerful than the top variant of the Velite 6.

What is the purpose of a car audio amplifier?

The car audio system serves functions such as playing music and receiving radio broadcasts. It can help divert the driver's attention when fatigued, enrich the driving atmosphere inside the vehicle, and prevent fatigue-related driving incidents. With the continuous development of the automotive industry and technology, modern car audio systems are designed to alleviate boredom for both drivers and passengers. They achieve high standards in sound quality operation and shock absorption, ensuring consistent audio output quality even on bumpy roads. Car audio systems mainly consist of three components: the head unit, speakers, and amplifier. The head unit includes CD players, MP3 players with CD changers, with MP5 being the most common type.

Is It Necessary to Replace a Cracked Lower Control Arm Bushing?

The lower control arm in a vehicle's suspension system plays a crucial role in bearing loads, guiding the wheels, and absorbing vibrations. Over time, the rubber bushings of the lower control arm are prone to cracking, making it necessary to replace them. Failure to do so can significantly impact the vehicle's stability and handling. Since these bushings are made of rubber, aging and wear are common over extended periods. The functions of the lower control arm bushings are as follows: 1. Reduced Stability When Damaged: If the lower control arm bushings at the front axle or tire area are damaged, symptoms may include a loose or unstable feeling in the chassis suspension while driving, sometimes accompanied by unusual noises. At high speeds, the vehicle's stability will noticeably deteriorate. 2. Worsened Handling: The vehicle may struggle to maintain a straight-line direction. If the bushing is completely broken, replacement is mandatory, as the lower control arm is a critical component connecting the front axle to the tire. 3. Importance of the Lower Control Arm: The lower control arm is a vital part linking the front axle and the tire. If it fails, the tire alignment may shift, potentially damaging other connected components. Damage to the lower control arm bushings is often due to rubber fractures, which are visibly noticeable at the connection points, sometimes even fully detached.

What are the symbols for China's National Emission Standards from Stage I to Stage V?

From Stage I to Stage V, the emission standard symbols are I, II, III, IV, and V respectively. On July 1, 2000, China first introduced the National Stage I Emission Standard. Since it was based on European emission standards and aligned with international standards, Roman numerals were also adopted for the symbols from Stage I to Stage VI. Currently, China has begun implementing the National Stage VI standard. The Stage VI standard is divided into two phases: "Stage VI a" and "Stage VI b," which were uniformly implemented nationwide on July 1, 2020, and July 1, 2023, respectively. The Stage VI standard is extremely stringent, far exceeding Europe's Stage VI emission standards and the U.S. Tier 3 standard, making it one of the strictest emission standards globally. As a result, the implementation period for the Stage VI standard will also be longer. Methods to check a vehicle's emission standard are as follows: Check the vehicle's factory certificate: For new vehicles, you can check the vehicle's factory certificate or the vehicle conformity certificate. Log in to the public query platform on the environmental protection website: Log in to the public query platform on the Motor Vehicle Environmental Protection Website to verify. You will need to enter the vehicle's VIN (Vehicle Identification Number) and the last six digits of the engine number.

How to Save Fuel in the Era of High Oil Prices?

Here are some fuel-saving methods for cars: 1. Proper throttle control: Avoid sudden acceleration during daily driving. 2. Try not to drive at excessively high speeds or frequently overtake: For most vehicles, maintaining a speed of 60-80 km/h in the highest gear is the most fuel-efficient. Control throttle output and try to maintain a steady speed. 3. Avoid sudden braking: Sudden braking consumes more resources than sudden acceleration, including wasted fuel from the injectors, brake pad wear, and tire wear.
