What is the solution for H4 headlights not focusing light?

H4 single-installation xenon lights have the biggest issues of light scattering and slow flickering. The solution is to install a lens. The structure of H4 model headlights combines high and low beams in one reflector bowl, which has two focal points. Replacing with xenon lights makes it difficult to align both focal points simultaneously, resulting in scattered light after modification for some vehicles. Here are specific details about H4 model headlights: 1. H4 headlights are a type of automotive headlight bulb specification and model. H4 is a dual-filament, three-pin bulb with both low and high beams in one bulb, typically rated at 55W for low beam and 60W for high beam; or 90W for low beam and 100W for high beam. 2. The performance of these headlights is relatively poor. The reflector bowl is too large, causing the emitted light to scatter excessively and not focus well. If modified with xenon or LED lights, the effect is comparatively worse with severe divergence, which can dazzle oncoming vehicles.

How many liters of engine oil should be added for the Toyota Land Cruiser 4.0?

The Land Cruiser 4.0 requires 6 liters of engine oil. Below is relevant information about the Land Cruiser: 1. Introduction: The Land Cruiser is the LAND-CRUISER 200 produced by Toyota, an imported ORV off-road vehicle manufactured by Toyota. While inheriting the original design DNA, its appearance evolves towards a style with a "freshness and advancement" of the new era. It is a hardcore off-road vehicle with four-wheel drive, a wheelbase of 2850 mm, and four-wheel disc brakes. 2. Configuration: The Land Cruiser employs the latest technologies and features such as the Crawl Control low-speed cruise driving assist system, KDSS kinetic dynamic suspension system, HAC hill-start assist control system, and the adoption of the VVT-i system. These enhancements not only improve durability, reliability, and off-road performance but also achieve a higher sense of luxury and quality, truly making it a world-class SUV.

Can a swollen battery still be recycled?

Once a battery is swollen, it is considered scrapped, and merchants will not attempt to repair it. Trade-in programs essentially recycle the lead and plastic at a discounted rate, regardless of the battery's condition. A swollen battery cannot and should not be repaired; it is recommended to replace it directly. This is because a swollen battery is prone to reverse polarity—where the positive terminal becomes negative and the negative terminal becomes positive—which can cause the charger to burn out and damage the controller. In the worst-case scenario, if the controller and charger lack comprehensive protection features, it could even lead to a vehicle fire. Battery swelling is one of the common causes of battery failure, typically manifesting as bulging on both sides. The primary reasons for swelling are excessive charging or discharging currents, leading to rapid temperature increases inside the battery. If the gas cannot vent in time, the pressure builds up until the battery swells or deforms. Upon discovering a swollen battery, prompt repair or replacement is necessary. During maintenance, it is crucial to inspect the charging system to ensure the charging voltage and current are within reasonable limits and that the generator and charging circuits are functioning properly.

Deduction Criteria for Designated Starting Point

Deduction criteria for designated starting point: 1. Scoring standards for hill parking: After parking, if the right side of the vehicle is more than 30 cm away from the roadside line, 10 points will be deducted; if it is more than 50 cm away, 100 points will be deducted; crossing or touching the line will result in a 100-point deduction. If the front bumper is not aligned with the pole line after parking, and the deviation is within 50 cm, 10 points will be deducted; if the deviation exceeds 50 cm, 100 points will be deducted. Failing to fully engage the parking brake will result in a 10-point deduction. 2. Scoring standards for hill starting: Failing to start within 30 seconds will result in a 100-point deduction; stalling once during starting will deduct 10 points; if the gear is not in neutral or park when starting the engine, 100 points will be deducted. If the vehicle rolls back less than 30 cm during starting, 10 points will be deducted; if it rolls back more than 30 cm, 100 points will be deducted.

What is the emission standard for 2009 cars?

2009 cars comply with the China IV emission standard. Below is relevant information about the China IV standard: 1. Introduction: The China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard. Automobile emissions mainly include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, it controls and reduces vehicle emissions to below specified limits. 2. Implementation timeline: In March 2009, the Industrial Policy Department of the Ministry of Industry and Information Technology convened a meeting with relevant enterprises to discuss the implementation of automobile emission standards (China III, China IV, China V), attended by major automotive manufacturers and engine producers. On December 21, 2010, the General Office of the Ministry of Environmental Protection of the People's Republic of China officially replied to the China Association of Automobile Manufacturers with the document Huan Ban Han [2010] No. 1390 "Reply Letter Regarding the Implementation Date of National Motor Vehicle Emission Standard Phase IV Limits".

Which is more comfortable to drive, a sedan or an SUV?

The comfort of a sedan is better than that of an SUV. Here are the differences between sedans and SUVs: 1. Safety performance: SUVs have lower safety, while sedans have higher safety. SUVs are generally taller with higher ground clearance and a higher center of gravity. If there is an emergency situation ahead while driving on the highway and sudden braking is required, the SUV is more likely to roll over. Sedans have lower ground clearance and a lower center of gravity, making them less prone to rollovers during sudden braking compared to SUVs. 2. Riding comfort: Sedans are more comfortable than SUVs. SUVs are generally taller, resulting in greater wind resistance during driving, which requires more effort to overcome. To achieve the same driving effect, SUVs consume more fuel. In contrast, sedans are designed with a curved shape and lower height, resulting in less wind resistance and lower fuel consumption during driving. 3. Fuel consumption: SUVs consume more fuel, while sedans consume less. The seat backrest of a sedan is designed in a "semi-reclined" position, providing a more comfortable seating posture during driving. On the other hand, the backrest of an SUV is generally designed to be upright, which may reduce comfort during long drives.
