The Toyota Prado engine number can be found on the front engine block, under the hood. The Toyota Prado engine number can be found on the front engine block under the hood. An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.). ), reactors, engines, etc. The precautions for using the engine are as follows: 1. Avoid driving in neutral: the engine itself has a deceleration and fuel cut-off function. If you use neutral, it does not promote fuel economy. If oil stains are found on the ground, determine whether there is an oil leak and communicate with the car 4S store in time to eliminate potential safety hazards. 3. For cars equipped with turbochargers, do not stop the engine immediately after avoir conducts at high temperature; or going up a hill, and let it idle for 10 minutes. After a few minutes, turn off the engine. Cars with turbochargers form carbon deposits several times faster than regular naturally aspirated cars. 4. When water is mixed or absorbed into the brake fluid, or impurities or sediments are found in the brake fluid, it should be replaced in time or filtered carefully. otherwise it will cause insufficient brake pressure, thereby affecting the braking effect.
1. The combustible mixture is too rich. The remaining unburned parts will accumulate on the spark plug electrode and be carbonized, causing the spark plug to flash abnormally until it is damaged by carbonization. The reasons for the fuel mixture being too rich are usually that the carburetor oil levelis too high, the main air volume hole of the carburetor is clogged and the air filter element is seriously clogged. Additionally, the carburetor choke is blocked and cannot be fully opened, or the enrichment valve is not working properly, which is also the reason why the fuel mixture is too rich.
2. Engine oil leak. During engine operation, if blue or black smoke is emitted from the exhaust pipe, this indicates that excess engine oil has entered the cylinder, which will cause a large amount of deposits to be produced of carbon by the spark plug electrode or its humidification. by engine oil and unable to produce sparks. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check whether the oil volume of the oil pump is too large and the rod sleeve seal and check valver are defective. For four-stroke engines, check the piston rings on the piston, especially the oil ring, whether it is worn or not. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are severely worn, the valve guide seal is hardened, or the seal lip is excessively worn, the mounting gap will be too large and the effect of The seal will be lost. Both of these abnormal situations will eventually cause oil in the valve rocker arm chamber to be drawn into the cylinder along the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.
3. In the ignition system, the magneto is demagnetized, the wire connections insideof the ignition coil and electronic ignition, the output end of the generator and the input end of the ignition coil are loose and the ignition advance time is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits on the spark plug electrode.
4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the selected calorific value is one or two ratios lower than that stated in the instruction manual, the spark plug temperature will be If it rises too high, the heat cannot be dissipated in time, causing a abnormal combustion and eventually melting the spark plug electrode and causing premature damage. When the spark plug itself is installed and used, someFaults are not easy to detect and also affect ignition performance. For example, if the spark plug is poorly sealed or the spark plug is solid, it should be adjusted or replaced in time. 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.
