Why does the oil pressure light come on at idle but goes off when accelerating?

The oil pressure light, also known as the oil warning light, illuminates when the oil pressure is insufficient. If the oil light comes on at idle but goes off when accelerating, the most likely cause is a malfunctioning oil pump. However, before checking the oil pump for faults, it's advisable to first inspect simpler and more easily identifiable issues such as whether the oil level is sufficient and whether the viscosity of the oil used meets the required specifications. Below is an introduction to the function of the oil pump: How the oil pump works: Most oil pumps are driven by the crankshaft via a belt or gears, meaning the oil pump starts working as soon as the engine is started. The oil pump is responsible for pumping oil from the oil pan through the oil passages to the upper parts of the engine, such as the camshaft, ensuring that components are adequately lubricated during high-speed operation. Types of oil pumps: There are two types of oil pumps: rotor pumps and gear pumps. At idle, they can provide oil pressure of around 300 kPa. If the oil pressure is too low, some engine components may not receive sufficient lubrication, leading to increased wear.

What are the installation techniques for tubeless tire valves?

Tubeless tire valve installation techniques involve threading the valve from the inside of the rim, with the smaller end passing through from the inside. Use pliers to pull it, and there is a circular groove at the back, so the base will snap into the rim's circle. To install the valve, it is not always necessary to remove the tire. You can deflate the tire, press down on the installation position of the valve to expose the valve base, cut off the original valve base, pull out the valve, and then replace it. Relevant information about tubeless tires is as follows: Introduction to Tubeless Tires: Tubeless tires are tires without inner tubes. These tires have an additional rubber sealing layer about 2-3 mm thick on the inner wall, which ensures good airtightness between the tire and the rim by using the tire's inner wall and the bead's airtight layer. The outer tire serves the function of the inner tube, and when the tire is inflated, the bead tightly combines with the rim, effectively preventing air leakage. Appearance: In terms of appearance, tubeless tires are not significantly different from ordinary radial tires. The main difference lies in the valve. The valve of a tubeless tire is directly fixed to the rim, whereas the valve of an ordinary tire is installed on the inner tube.

Can Temporary License Plates Still Be Used After Official Plates Are Issued?

They can be used within the validity period, but some road traffic regulations impose restrictions on vehicles with temporary license plates. For example, elevated roads in Shanghai have such restrictions. Additional Information: New Traffic Regulations on Temporary License Plate Placement: Starting from January 1, 2011, the temporary license plates for passenger vehicles were increased from 1 to 2, and the installation method was changed from 'placing' to 'pasting' in designated positions. One plate should be pasted on the lower left or right corner of the front windshield inside the vehicle, where it does not obstruct the driver's view, and the other should be pasted on the lower left corner of the rear windshield inside the vehicle. Running a Red Light with Temporary Plates: According to the new traffic regulations, motor vehicles without license plates are not allowed on the road. New vehicles must display either official or temporary license plates to be driven on the road. Starting from January 1, 2013, driving a motor vehicle on the road without displaying a license plate, or intentionally obscuring, damaging, or not installing the license plate as required, will result in a one-time deduction of 12 points.

What is the normal high pressure for car air conditioning?

Car air conditioning normal high pressure should be 3-7MPa (13-17kg/cm2 or 190-250Lbf/in2); normal low pressure should be between 0.15-0.25MPa (5-5kg/cm2 or 20-35Lbf/in2). Car air conditioning system: The car air conditioning system is a device that cools, heats, ventilates and purifies the air in the compartment. It can provide a comfortable riding environment for passengers, reduce driver fatigue and improve driving safety. Air conditioning has become one of the indicators to measure whether a car is fully functional. Disadvantages of car air conditioning: When the air conditioning is turned on, passengers should not smoke in the car. Because when the air conditioning is turned on, the air in the car circulates in a relatively closed environment. Firstly, the smoke is not easy to dissipate. Secondly, the tiny particles in the smoke will adhere to the air conditioning intake filter, causing long-term odor in the car. Regular professional air conditioning system cleaning and deodorizing maintenance is recommended.
