4h is high-speed four-wheel drive. 4h and 4l are two modes available on four-wheel-drive vehicles. 4h is the high-speed four-wheel-drive mode, while 4l is the low-speed four-wheel-drive mode. These two drive modes differ in terms of controlling the transmission and are used in different scenarios. Utilizing the appropriate four-wheel-drive mode based on terrain not only enhances the vehicle's off-road capability but also reduces fuel consumption to some extent. Usage scenarios for 4h and 4l modes: 1. Slippery surfaces: If driving on snow or slippery roads, the 4h mode is highly suitable, as it ensures sufficient traction while preventing excessive driving force that could cause wheel spin. 2. Climbing: Due to its high driving force, the 4l mode is ideal for steep slopes or off-road conditions, maximizing the vehicle's power output. 3. High-speed driving: High-speed four-wheel drive (4h) is not suitable for highway driving. For part-time four-wheel-drive vehicles, dry paved roads are not appropriate for using 4h or 4l modes; only the 2h mode should be selected.

What is the maximum temperature allowed for EA888 Channel 93?

093 channel steering angle is within the normal range between +3 to -3 degrees. The Volkswagen EA888 engine is a design by Volkswagen that integrates a series of advanced technologies including direct fuel injection, turbocharging, and variable valve timing, achieving a balance between power and fuel economy. Below is more related information: 1. EA888 Engine: The EA888 engine is the main power unit for Volkswagen Group's mid-to-high-end models, available in 1.8L and 2.0L displacements. It utilizes intake variable valve timing technology to effectively improve intake and exhaust efficiency, primarily achieved through a vane-type hydraulic adjuster located on the intake camshaft. The EA888 engine also features dual balance shafts positioned at the lower sides of the cylinder block, driven by the crankshaft and chain. The centrifugal force generated by the rotation of these balance shafts counteracts the centrifugal force produced by the crankshaft, significantly reducing vibration, thereby enhancing engine balance and lowering noise levels. 2. Timing Error Data Stream: Automotive timing error data streams can be analyzed using a dual-trace oscilloscope connected to the camshaft position sensor and crankshaft position sensor signals for comparison. Timing data errors indicate potential issues with the engine's timing chain, suggesting the need for timely replacement of the timing chain and tensioner to prevent further complications.

What is BYD's Battery Replacement Policy?

BYD's new energy vehicle core components come with a warranty period of 8 years or 150,000 kilometers, while the power battery cells are covered by a lifetime warranty. When the battery's power degrades by 20%, customers can apply for a free replacement. Below is more related information: Reasons behind BYD's new policy: 1. As a company that started with batteries, BYD's electric vehicles have inherent advantages. Although the world is pushing for the development of electric vehicles, it must be said that there are still many technological challenges to overcome. Among these, battery power degradation and driving range are the most concerning factors for the public. To address these concerns, BYD introduced its battery replacement policy to alleviate consumer worries. 2. BYD's ability to launch such a generous policy is largely due to its rapid development in recent years. Technologically, BYD has a long history of expertise, particularly in battery technology, which has allowed it to quickly surpass other domestic automakers in the new energy vehicle sector and closely follow international leaders like Tesla. BYD's confidence in introducing this policy reflects its belief in vehicle quality. If the quality were subpar, the cost of large-scale battery or motor replacements and warranties would be unsustainable for BYD.
