Will the engine fail to start without oil?

It is possible to start the engine without oil because the surfaces of various engine components still have residual oil when the engine is off. The engine can start initially when there is no oil. However, after a few minutes of operation, the engine temperature rises, and the remaining oil evaporates. Continuing to drive with insufficient oil will lead to poor lubrication, causing wear on engine components and potentially severe consequences such as cylinder scuffing, ultimately damaging the engine. The role of engine oil: to lubricate moving parts and reduce temperature. As the engine temperature increases, without the lubrication and cooling provided by oil, the first components affected are the cylinder, piston, piston rings, crankshaft, and bearings. The bearings and crankshaft may fuse together due to excessive heat, preventing rotation and causing serious damage to the engine. Remember, starting the engine without oil is strictly prohibited.

Is It Normal for a New Car to Smoke and Have a Burning Smell?

It is normal for a new car to smoke and have a burning smell, which is caused by the evaporation of anti-corrosion coatings and oil stains on the engine's outer surface when heated. Heating and Evaporation: After the engine runs for a while, its outer surface becomes very hot, especially components like the exhaust pipe. These parts have various anti-corrosion treatments, including coatings. Initially, when heated, these coatings will partially evaporate, releasing a pungent odor. Surface Oil Stains: If there are oil stains on these components, they will also evaporate when heated, producing an unpleasant smell. Additionally, there are many plastic parts and decorative panels in the engine compartment, which can also emit odors when heated. However, there is no need to worry, as these smells will disappear over time once the evaporation process is complete.

What are the key points for assessing damage to vehicle chassis suspension components?

Key points for assessing damage to vehicle chassis suspension components: 1. Determine the repair method for the damaged area before vehicle maintenance: Generally, insurance companies prioritize repairing damaged components, meaning if the damaged parts can be repaired and their normal functionality is not affected post-repair, they should be repaired. If the damaged parts cannot be repaired, they can be replaced. 2. Determine the vehicle repair cost amount: Insurance companies usually assess vehicle repair costs based on the qualification level of the repair facility. For replaced damaged components, the pricing is based on the regional market price of the parts. 3. Conduct damage assessment and repairs at the same location whenever possible: Insurance companies have different pricing standards for damage assessments at 4S dealerships and independent repair shops, as they confirm repair cost standards based on the actual repair facility's standards.

What are the reasons for heavy steering in Wuling Hongguang?

Wuling Hongguang heavy steering reasons are as follows: 1. Dirty power steering fluid: Power steering fluid is the force transmission medium. If the fluid is dirty, it will cause poor circulation, making steering difficult. In more severe cases, the power steering pump may produce a "buzzing" sound. 2. Lack of power steering fluid or oil leakage: Check the relevant system for signs of oil leakage, focusing on the power steering fluid reservoir, power steering hoses, and steering gear. 3. Poor lubrication: Excessive tightness or lack of lubrication in the tie rod end ball joints, or bending of the steering shaft and sleeve causing jamming, etc. These are mechanical failures in the steering system.
