What are the causes and solutions for low oil pressure?

The causes and solutions for low oil pressure are as follows: Insufficient oil volume: If the oil volume is insufficient, the oil pump's pumping capacity will decrease or fail to pump oil due to air intake, leading to a drop in oil pressure. The crankshaft and bearings, as well as the cylinder liner and piston, will experience increased wear due to poor lubrication. Check the oil level in the oil pan before each shift to ensure sufficient oil volume. Excessive clearance between the crankshaft and bearings: After prolonged engine use, the clearance between the crankshaft and connecting rod bearings gradually increases, preventing the formation of an oil wedge and causing a drop in oil pressure. It has been measured that for every 0.01mm increase in this clearance, the oil pressure drops by 0.01Mpa. The crankshaft can be reground, and connecting rod bearings of corresponding sizes can be selected to restore the clearance to technical standards.

What brand is the tire with a scorpion logo?

It is the Pirelli brand. Pirelli's earliest Scorpion tire dates back to 1981, when Pirelli specially developed the Scorpion run-flat tire for the Lamborghini LM002 ultra-high-performance off-road vehicle. The relevant introduction about tires is as follows: Tire introduction: Tires are rubber products, so even if not used, they will naturally age. Before using stock tires, it is necessary to check for cracks and rubber aging before use. Tire storage method: If stored in a suitable environment with constant temperature and away from light, the speed of rubber aging will slow down significantly, and there will be no problem using them even after several years. If stored in a place with direct sunlight and large temperature differences, causing rubber aging and cracking, even if unused, they are not suitable for use. Rubber without elasticity cannot provide the necessary grip.

Do automatic transmission cars have a clutch pedal?

Automatic transmission cars do not have a clutch pedal, but they do have a clutch - an automatic clutch that does not require operation, hence no clutch pedal. The clutch in an automatic transmission car is located inside the gearbox, and there are several clutches controlled by the gearbox's electronic control system. The biggest difference between manual and automatic transmission cars is that manual transmission cars require foot coordination for gear shifting, while automatic transmissions don't need the driver to press a clutch pedal at all. Automatic transmissions can be further divided into conventional automatic transmissions, semi-automatic transmissions, CVT continuously variable transmissions, and DSG dual-clutch transmissions. The clutch acts like a bridge between the engine and the transmission, responsible for interrupting and connecting power transmission. Although automatic transmissions don't have a clutch pedal, it doesn't mean they lack a clutch. Automatic transmissions with gears not only have clutches but often multiple ones - each speed gear has its own set of clutches. These clutch plates continuously engage or disengage based on changes in vehicle speed, engine RPM, and accelerator pedal position to achieve automatic gear shifting.

What Causes Slight Shaking During Auto Hold?

The causes of slight shaking during auto hold include excessive carbon buildup and aging engine mounts. Specific reasons are as follows: Excessive Carbon Buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup in the engine, the air-fuel mixture becomes too lean during cold starts, making it difficult to start. In such cases, the car may only start easily when the carbon deposits become saturated with gasoline. The gasoline absorbed by the carbon deposits is then drawn into the combustion chamber by the engine's vacuum, causing the mixture to become too rich. This fluctuation between lean and rich mixtures leads to idle shaking after a cold start. Aging Engine Mounts: Car shaking can also be related to aging engine mounts. Engine mounts are essentially the engine's vibration damping system. They are responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations can be transmitted to the steering wheel and cabin, causing noticeable shaking at idle.

What Oil Should Be Used for Screw Pumps?

Screw pumps require screw-type air compressor oil. The types and maintenance methods of screw-type air compressor oil are as follows: Types of screw-type air compressor oil: There are mineral-based Aoliang screw air compressor oils, which generally have a service life of about 3,000 hours, and fully synthetic Aoliang air compressor oils, which have a service life of over 6,000 hours but are more expensive. You can choose according to your needs. Maintenance of screw pumps: When stopping the screw pump, first close the discharge stop valve, and then close the suction stop valve after the pump has completely stopped. Due to the relatively long length and poor rigidity of the working screw, it is prone to bending, which can cause operational issues. The shaft system connection must be well aligned; alignment is best performed after installation and positioning to avoid deformation caused by pipeline stress. The connecting pipelines should be independently fixed to minimize stress on the pump, etc.

Does the Dash Cam Have to Be in the Car to View Footage?

It is not necessary for the dash cam to be in the car to view footage; it can be used anywhere with a stable power supply. The recording capabilities and functions of a dash cam are as follows: Recording Capabilities of a Dash Cam: Generally, a dash cam is designed to record the road conditions directly in front of the vehicle. Some models also feature dual recording, capturing both front and rear views. However, whether it's a single or dual recording dash cam, none can view or record the interior of the car. Functions of a Dash Cam: Many car owners install dash cams in their vehicles. The primary function of a dash cam is to record events happening in front of the car, which can serve as crucial evidence in the event of an accident.
