Anonymous users2024-02-07If the engine water temperature of the car is too high or too low, it basically means that the cooling system of the car has a faulty problem.
The key to the cooling system of the car is to dissipate heat into the air to avoid the role of overheating the engine, the car engine runs well in a moderate high temperature state, if the Wendy of the engine is too low, it will accelerate the wear and tear of the car components, affect the efficiency of the car engine is low, so that the pollutants of the car will be emitted more, of course, the cooling system of the car can also maintain the engine temperature of the car in a good range, so that it can maintain a constant temperature, The antifreeze temperature of most cars is around 93 degrees Celsius, and the car's engine is running at its best.

Anonymous users2024-02-06The most common failure of an oxygen sensor is failure, and there are two main reasons for this:
The first is clogged with carbon particles, at which point the signal voltage of the oxygen sensor will be too high, and the engine computer will therefore issue instructions to reduce the amount of fuel injected, making the mixture too thin.
The second is that dust and oil block the through hole between the oxygen sensor and the atmosphere, at this time, the signal voltage of the oxygen sensor will be low, and the engine voltage will indicate that the injector will inject more fuel, causing the mixture to be too thick.
The oxygen sensor is an important component of the electronically controlled fuel injection engine, and if it fails, it will not only exceed the emission standard, but also worsen the operating condition of the engine.
