The automobile oil pump is installed inside the engine, usually located inside the oil pan, which can be seen by removing the oil pan. The oil pump is connected to a filter screen at the bottom. The function of the oil pump is to raise the oil to a certain pressure and then forcibly deliver it to the moving surfaces of various engine components. Oil pumps can be divided into two types based on their structural form: gear type and rotor type. Gear-type oil pumps are further divided into internal gear type and external gear type, with the latter generally referred to as gear-type oil pumps. When the engine is running, the drive gear on the camshaft drives the transmission gear of the oil pump, causing the drive gear fixed on the drive gear shaft to rotate, which in turn drives the driven gear to rotate in the opposite direction, delivering the oil from the inlet chamber to the outlet chamber through the tooth gaps and pump walls.

Why does the reversing camera guide line disappear on the Camry?

Camry reversing camera guide line disappears due to display settings. What configurations does the Camry have: Configuration parameters of the 2021 Camry. The Camry has launched two models powered by a 2.0L engine and a 2.5L engine respectively, as well as a hybrid model equipped with a 2.5L engine. How to handle the disappearance of the reversing camera guide line on the Camry: Generally, there is a camera switch control in the display settings. Turn the switch to ON to resolve the issue. If the camera is faulty, replace the reversing camera. Wiring issues are the most common problem, as the reversing camera wiring harness runs from the dashboard all the way to the trunk area, covering a long distance. It is likely that a section of the wiring harness or a connector has poor contact, requiring thorough inspection.

What is the normal tire pressure for the Geely Binyue?

The normal tire pressure for the Geely Binyue is 2.2-2.5 bar. Generally, the manufacturer's recommended tire pressure can be found in places such as the vehicle's user manual, the label near the B-pillar of the driver's door, the drawer next to the driver's seat, and the back of the fuel tank cap when refueling. According to the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. In summer, the tire pressure is generally set to the lower limit of the standard tire pressure for car tires. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. In winter, the tire pressure should be based on the standard tire pressure for car tires, and it can be appropriately increased by about 0.2 bar.

What are the reasons for low tire pressure in Accord?

The reasons for low tire pressure in Accord are: air leakage from the tire valve; reduced tire sealing performance due to wheel hub deformation; uneven tire force distribution. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and easy deviation, which are unfavorable factors for driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the function of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear; The friction between the tire and the ground multiplies, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowout; Increases tire body deformation, making the tire side prone to cracks, while generating flexural movement, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, cord breakage, and also increasing the tire's contact area with the ground, accelerating shoulder wear.

What is the actual fuel consumption of the Tharu 1.4T?

The real fuel consumption range of the Tharu 1.4T is 6.98 to 9.12 liters per 100 kilometers. Vehicle Introduction: The SAIC Volkswagen Tharu features a square front face with a two-bar grille extending to the headlights, paired with a rugged bumper design and a prominent central logo. The new car's design language somewhat resembles the Teramont, with chrome trim on the grille using an armor-style design in its original color, combined with black honeycomb trim panels, giving it a tough appearance. The bumper adopts a "big beard" design, with black surrounds and a silver skid plate. As a compact SUV, the overall look conveys an off-road style. Powertrain Introduction: The 1.4T engine in the Tharu delivers a maximum horsepower of 150 and a peak torque of 250, paired with a DQ-speed dual-clutch transmission in the drivetrain. On paper, this powertrain performance is decent, though not as powerful as the 2.0T. From actual test results, the Tharu's 0-100 km/h acceleration time remains at 9 seconds, which is entirely sufficient for everyday driving scenarios.
