What does the auto parts to whole vehicle price ratio mean?

Auto parts to whole vehicle price ratio refers to the ratio between the price of parts and the sales price of the whole vehicle. Specific meaning of the ratio: The auto parts to whole vehicle price ratio specifically refers to the sum of the prices of all installed parts of the vehicle divided by the sales price of the whole vehicle, multiplied by one hundred percent, resulting in a percentage coefficient. Calculation method of the ratio: Calculating the complete parts to whole vehicle price ratio is quite difficult, as manufacturers do not disclose the prices of all components. Therefore, simplified versions such as "50 frequently damaged parts ratio" and "100 frequently damaged parts ratio" have emerged as reference methods. Moreover, different manufacturers adopt varying calculation approaches.

What Causes the Loud Buzzing Sound in the Engine?

It may be caused by a malfunctioning temperature sensor or thermostat, or excessive clearance between the piston and cylinder wall. Below are detailed explanations about automobile engines: Overview: The automobile engine is the device that provides power to the vehicle, determining its performance, fuel efficiency, stability, and environmental friendliness. Depending on the power source, automobile engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. Others: Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston movement and outputting power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, excellent thermal efficiency, and better fuel economy and emission performance compared to gasoline engines.

What causes difficulty starting after a hot engine shutdown?

Difficulty starting after a hot engine shutdown can be attributed to the following reasons: Fuel injector leakage: While fuel injector spray is normal operation, leakage constitutes additional fuel supply. The more severe the injector leakage, the richer the air-fuel mixture becomes, leading to hard starting when the engine is hot. Canister purge valve failure: During hot starts, fuel atomization is normally adequate without requiring additional vapor. If the charcoal canister continues supplying vapor to the intake, it creates an over-rich mixture that makes starting difficult. Fuel quality issues: Highly volatile fuel can create excessive vapor pressure in the fuel rail. When this pressure exceeds the fuel system pressure, vapor lock occurs. This results in overly lean fuel vapor being injected, causing starting difficulties.

How many hours does new car maintenance take?

Car maintenance typically takes about 1 hour. The duration depends on the maintenance items. If it's just changing the engine oil, oil filter, air filter, and cabin air filter, it usually takes about 1 hour including car washing time. For more comprehensive maintenance like changing engine oil, three filters, transmission fluid, cleaning the catalytic converter or throttle body, it will take at least 2 to 3 hours. The maintenance time is directly proportional to the number of maintenance items. Below is relevant information: Notes: Generally, minor maintenance should be performed every six months or every 5,000 kilometers driven. Depending on the number of vehicles in the shop and staff workload, minor maintenance usually takes between 20 minutes to 1 hour. The main content includes changing engine oil and oil filter, and inspecting the air filter. Maintenance content: Minor maintenance doesn't involve many items, mainly checking some wear-prone parts including engine oil and three filters. Generally, the first maintenance should be performed at 5,000 kilometers or one year of use, while the second maintenance at 10,000 kilometers or two years of use. The main content is inspecting the car's three major components: engine, chassis, and transmission. Always keep records of car maintenance for future reference if problems arise.

What are the symptoms of a bad stabilizer bar bushing?

When the stabilizer bar bushing is worn out, there will be abnormal noises such as clunking or squeaking sounds during driving and braking. These noises occur every time the vehicle goes over bumps or uneven roads, not from collisions but from the rubber being squeezed. In the second stage, the chassis may produce "thudding" or "rattling" sounds, which feel like blunt objects colliding with each other. These sounds are noticeably louder than the "thumping" noise from the suspension. Below is relevant information: Working Principle: The stabilizer bar bushing is designed and installed on the lower control arms of both front wheels to control the overall symmetry of the front wheels. Its main function is to manage the front wheels' camber angle, maintain the tracking ability of the steering wheels, prevent excessive lateral roll of the body during turns, improve ride comfort, enhance the overall rigidity of the chassis, and increase the vehicle's driving stability. Solution: If the bushing is damaged, owners with strong DIY skills can purchase and replace it themselves. Before replacement, to further confirm the issue, a small amount of lubricant can be sprayed to see if the noise improves. If there is improvement, replacement can be considered. Of course, owners with complete tools can also remove the tire, detach the stabilizer bar link ball joint, and shake the stabilizer bar by hand to check for any gaps, further confirming the condition of the bushing.
