Motorcycle fuel pump not working may be caused by damage to the fuel pump, poor contact or open circuit in the fuel pump wiring, insufficient gasoline in the tank, clogged fuel lines or fuel filters preventing fuel flow, or vacuum formation in the fuel tank making it difficult to deliver fuel. If it's the oil pump that's not working, check whether the pump itself is damaged, whether there are issues with the pump drive mechanism (such as the oil pump gear or chain), whether the oil filter screen or filter element and oil passages are clogged, or whether the oil level is too low. Below are the functions of car preheating in winter: Functions of preheating: Reduces engine wear and checks whether the car's fuel system, electrical system, cooling system, and mechanical transmission are functioning normally. Reasons for preheating: After a car has been parked for a long time, the engine oil flows back to the oil pan at the bottom of the engine, leaving the upper part of the engine without lubrication. It takes about 30 seconds after starting for the oil pump to circulate oil to the parts of the engine that need lubrication the most, such as the pistons, connecting rods, and crankshaft.

What is the name for the storage compartment inside the car door?

The interior panel inside the door is called a storage compartment. Below is relevant information about car doors: Introduction: Car doors provide access for drivers and passengers to enter and exit the vehicle while isolating external disturbances. They also offer some protection against side impacts, safeguarding occupants. Function: The aesthetic appeal of a car is also related to the design of its doors. The quality of car doors is primarily reflected in their anti-collision performance, sealing performance, ease of opening and closing, as well as other functional indicators. Anti-collision performance is particularly important because during a side impact, the buffer distance is very short, making it easy for occupants to be injured.

What is the suitable tire pressure for Haval H6 in summer?

Haval H6's tire pressure in summer should be maintained between 2.3-2.5 bar. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear of the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing tire elasticity and increasing load during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, causing internal cracks or blowouts. Hazards of insufficient tire pressure: Increases friction with the road surface, leading to higher fuel consumption; Makes steering heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive compression; Weakens cord and rubber functionality, leading to delamination or cord breakage, and excessive friction with the rim causing bead damage and abnormal wear; Multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire deformation, causing sidewall cracks and excessive flexing, leading to overheating, rubber aging, cord fatigue, and accelerated shoulder wear.

What Causes Increased Fuel Consumption in Sedans?

Car fuel consumption may increase due to the following reasons: Issues with spark plugs and high-voltage wires: As the vehicle's usage time extends, abnormalities may occur in the ignition circuit, leading to increased fuel consumption. Fuel system obstruction: Prolonged use of the vehicle can easily cause carbon buildup, resulting in poor fuel system flow. It is necessary to promptly clean the fuel injectors and throttle body to achieve the effect of reducing fuel consumption. Tire wear level: The wear level of the car tires can also affect the vehicle's fuel consumption. Severe tire wear can cause slipping, leading to increased engine power output and higher fuel consumption.
