What Causes Engine Failure?

Engine failure can be caused by malfunctions in the fuel supply system, ignition system, intake system, exhaust system, and various sensor components. A faulty oxygen sensor near the three-way catalytic converter can also trigger engine failure. Vehicle owners can use the elimination method to troubleshoot each component individually. If the engine warning light comes on while driving, it is advisable to visit a repair shop to check the fault codes. In automotive design, to ensure the engine operates in good condition and maintains its normal working lifespan, oxygen sensors are installed to monitor the engine's combustion status. Poor combustion conditions can lead to excessive engine wear, resulting in the illumination of the engine warning light.

Will Changing Tires Affect the Tire Pressure Monitoring System?

Changing tires does not affect the tire pressure monitoring system because the sensors of the tire pressure monitor are placed on the wheel hubs. After changing tires, the tire pressure monitoring system can still accurately detect the tire pressure. There are three commonly used methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure of a tire decreases, the weight of the vehicle causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data of the actual pressure in all four tires as a direct system does.

Symptoms of Engine Misfire?

Automobile engine misfire manifests as: 1. Unstable idling and abnormal engine vibration; 2. Significant power reduction; 3. Difficulty starting the vehicle and engine prone to stalling; 4. Black smoke emitted from the exhaust pipe. The primary causes of engine misfire stem from the ignition system and fuel injection system. Severe burning of the contacts in the distributor cap of the ignition system can cause spark jumping, mostly occurring between corresponding terminals on the cap, leading to erratic idling and severe power loss. Faulty ignition coils can also result in misfire, often causing severe burning of the distributor cap. Issues with the ignition coil most commonly lead to sudden severe power loss and engine stalling.

Where is the camshaft located?

The camshaft can be positioned in three ways: lower-mounted, middle-mounted, and overhead-mounted. In a lower-mounted valve train, the camshaft is located in the crankcase. In a middle-mounted valve train, the camshaft is positioned in the upper part of the engine block. In an overhead-mounted valve train, the camshaft is situated on the cylinder head. Most mass-produced vehicles today are equipped with overhead camshaft engines. Additional relevant information is as follows: 1. Camshaft arrangement: Common drive methods between the camshaft and crankshaft include gear drive, chain drive, and toothed belt drive. Lower-mounted and middle-mounted camshafts typically use cylindrical timing gears for driving the crankshaft, usually requiring only one pair of gears. If the gear diameter is too large, an additional idler gear can be added. To ensure smooth meshing and reduce operational noise, helical gears are commonly used for timing gears. 2. Chain drive: Chain drive is often used between overhead camshafts and the crankshaft, but its reliability and durability are inferior to gear drive. Toothed belts have replaced drive chains in many high-speed engines due to their quieter operation, reliability, and lower cost. However, some high-power engines still use chain drives. For double overhead camshafts, the exhaust camshaft is typically driven by the crankshaft via a toothed timing belt or chain, while the intake camshaft is driven by the exhaust camshaft through a metal chain. Alternatively, both intake and exhaust camshafts may be driven directly by the crankshaft through a toothed belt or chain.
