What is the normal temperature of car engine oil?

Car engine oil normally operates at a temperature between 70 to 90 degrees Celsius. The working temperature of engine oil typically ranges from 70 to 90 degrees Celsius, with some areas potentially being higher, but it should not exceed the coolant temperature. Additionally, higher speeds can lead to relatively higher temperatures, reaching around 100 to 110 degrees Celsius. However, if the temperature consistently tends to exceed 120 degrees, it should be inspected. Engine oil, also known as motor lubricant, serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives are used to compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are an essential part of the lubricant.

Is It Advisable to Buy a New Car That Has Been in Stock for a Long Time?

It is not recommended to purchase a new car that has been in stock for a long time. This is because such vehicles have been parked for extended periods without undergoing periodic inspections and maintenance. Additionally, due to the lack of proper storage management, many stock cars are stored outdoors, exposed to sun and rain, which can lead to moisture damage and aging of electronic components and rubber parts. Typically, a car is considered a stock vehicle if it has been in inventory for more than three months or half a year. For imported cars, due to factors like transportation cycles, vehicles manufactured over a year ago are also classified as stock cars. For cars that have been parked for too long, the aging of electronic components and rubber parts is often undetectable without professional testing equipment. Moreover, many vehicles that have been in stock for extended periods may also suffer from issues like lack of oil or battery power.

What are the reasons for the engine warning light to come on?

There are usually the following reasons for the engine warning light to come on: 1. Poor combustion state: Poor combustion state of the engine is the main reason for the engine warning light to come on. During driving or at the moment of ignition, the engine warning light on the dashboard (usually red or yellow) will illuminate. In most cases, it will not disappear automatically, while in a few cases, it may disappear on its own. This is what is referred to as the engine warning light coming on. 2. Engine knocking: In the first scenario, some engine warning lights may come on, while others may not. In the second and third scenarios, the engine warning light will inevitably come on. 3. Internal reasons for the engine warning light coming on: Poor fuel quality; unclean engine cylinders with accumulated carbon deposits. Over time, the engine will inevitably accumulate some carbon deposits. These deposits can alter the engine's design parameters and, due to their unstable nature and heat retention, can cause disordered ignition, leading to engine knocking.

Why does a van suddenly stall and fail to start while driving?

The reasons why a van suddenly stalls and fails to start while driving are as follows: 1. Abnormal fuel supply: When it is confirmed that there is fuel in the tank, check whether there is fuel in the carburetor. If there is no fuel, it means the fuel line from the tank to the carburetor is blocked and should be cleaned and unclogged. If there is fuel in the carburetor but the engine still cannot start, check whether the carburetor fuel filter is blocked or if the main jet is dirty. 2. Engine overheating: Excessive temperature and poor lubrication can cause the piston and cylinder to seize, leading to stalling. After diagnosis, check whether there is lubricating oil in the crankcase. If there is little or no lubricating oil, check whether the oil pan or drain plug is leaking, or simply add the specified lubricating oil.

How many people are required for the HOV lane at minimum?

The HOV (High-Occupancy Vehicle) lane requires vehicles entering this lane to have at least 2 or more occupants (including the driver). Single-occupant vehicles are prohibited. The HOV lane is also known as the carpool lane. When this sign appears, it defaults to allowing only vehicles with 2 or more occupants. The HOV lane is marked with HOV-2+, or a combination of 2+ and a car image. Special cases may have unique markings, such as in Wuxi and other regions where HOV lanes require 3 or more occupants, marked as HOV-3+, or with 3+ added next to the car on the sign. The significance of the HOV lane: The dedicated HOV lane originates from Europe and America, playing a positive role in optimizing travel structures and road resource allocation, reducing the occupation of road resources by empty vehicles, and promoting carpooling and green travel. Carpooling reflects the encouragement of the sharing economy, providing a new solution to improve the efficiency of human-vehicle-road coordination, promote dynamic balance in transportation supply and demand, and optimize travel methods.
