  • Auto Parts Factory:How To Detect Oxygen Sensor Failure

    In the electronically controlled gasoline injection engine, the oxygen sensor for closed-loop control of the fuel system is an important electronic component, used to monitor the oxygen content in the exhaust gas, and fed back to the ECU with a voltage signal to keep the air-fuel ratio at 14.7. At the same time, it is also an endorsement alarm component for multiple fault signals. The common failure of the zirconia sensor is that the surface is covered with lead or carbide, which results in gas impermeability and oxygen ion diffusion and failure. When the fault lamp alarms and the sensor fails to read, it is necessary to diagnose it, because the oxygen sensor alarm is not necessarily a sensor failure,…

  • This Is How The Car Chassis Is Damaged

    Hitman 1: Speed ​​bump Vulnerable parts: front bumper extension, exhaust pipe, suspension The speed reduction belt is used to force the vehicle to slow down. However, there are no standards in the design of the speed reduction belts. They have different heights and different shapes. Some are relatively high, and some car owners have no habit of decelerating through the speed reduction belt, which is very desirable. Generally, the front bumper and exhaust pipe are relatively easy to be pinched. Coping method: Reduce the speed, so that the general speed reduction belt can pass safely, unless your chassis is too low. Hitman 2: The top and bottom of a steep slope Vulnerable parts: front bumper, exhaust pipe, tie rod, etc.…

  • Automotive Engine Principle

    Working principle of gasoline engine (gasoline engine) Four-stroke gasoline engine is a good mixture of air and gasoline at a certain ratio. car engine car engine Aerated gas is sucked into the cylinder during the intake stroke, and the mixed gas is compressed and ignited to generate heat energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to reciprocate linear motion, and output mechanical energy to the outside through the connecting rod and crank flywheel mechanism. A four-stroke gasoline engine completes a working cycle in the intake stroke, compression stroke, power stroke, and exhaust stroke. ⑴Intake stroke Driven by the crankshaft, the piston moves from top dead center to bottom dead center. At…

  • Overview Of Auto Parts

    I. Overview of Auto Parts Auto parts are the units that make up the whole car and products that serve the car. There are tens of thousands of components in a car, with a wide variety and complex structural forms. Classification of auto parts Classified by standardization. (1) Parts A single finished product, a single product that does not use an assembly process, or two or more products that have a specified function and are usually not disassembled are parts, such as tires, wheels, and pistons. (2) Unit body A functional combination consisting of any combination of parts and components with a certain functional characteristic, which can usually work independently in different environments (3) Subassembly When two or more parts…
