What Causes Difficulty Starting a Hot Engine?

Reasons for difficulty starting a hot engine: 1. Carbon deposits: At high temperatures, carbon deposits have a strong adsorption effect on fuel. Excessive carbon buildup on pistons, throttle valves, and intake pipes can absorb part of the fuel, resulting in too much air and too little fuel, thereby affecting engine startup; 2. Faulty coolant temperature sensor and intake air temperature sensor: If these two sensors are damaged, they cannot provide correct temperature signals; 3. Fuel system failure: When the car is hot, the temperature is very high. If the owner opts for cheap, low-quality gasoline from small gas stations, it can cause gasoline to evaporate, resulting in an overly lean air-fuel mixture. Additionally, poor fuel pump operation or fuel injector leakage can also make it difficult to start.

What Causes an Increase in Car Antifreeze?

An increase in car antifreeze is often due to engine cylinder head gasket failure, which is a dangerous situation as engine oil enters the cooling system. Antifreeze is a crucial substance in the cooling system, circulating in the radiator and carrying away engine heat through pipes. Besides preventing freezing and cooling, it also has excellent properties such as preventing boiling in summer, rust removal, and corrosion resistance. Situations requiring antifreeze replacement include: 1. The color of the antifreeze in the reservoir has changed, showing a noticeable difference from the original; 2. Sediments or floating impurities are visible in the antifreeze; 3. The antifreeze level exceeds the designated limit; 4. Instruments detect insufficient freezing point of the antifreeze; 5. The engine temperature is too high.

What is the troubleshooting method for valve ablation and air leakage?

Valve ablation and air leakage troubleshooting methods are as follows: 1. Inspection: Check the sealing between the valve and the valve seat ring. Introduce 490~588 kPa compressed air into the cylinder and listen at the intake manifold and exhaust manifold respectively. Determine whether the air leakage is from the intake valve or the exhaust valve based on the sound of the leakage. 2. Characteristics of ablation: After valve ablation, the engine shows weak operation, black smoke from the exhaust pipe, and poor sound when firing. If the exhaust valve is ablated, the exhaust pipe will overheat or even turn red. 3. Determining valve ablation fault: The valve spring should be disassembled and inspected for obvious deformation and whether its stiffness meets the standard; check the valve and seat for ablation, grooves, pits, and pitting. Repair as much as possible according to the repair specifications, and replace with new parts if necessary.

How Long Does It Take for the Engine to Cool Down After Shutting Off?

Engine cooling takes about half an hour after shutting off. Engine cooling refers to the heat dissipation and insulation measures taken for components operating in high-temperature environments during engine operation, ensuring that the temperature of heated parts does not exceed the allowable range of material strength. Engine cooling methods include: 1. Film cooling, where liquid propellant or gas forms a film on the heated wall to prevent heat transfer from the gas to the wall, known as liquid film cooling or gas film cooling; 2. Sweat cooling, also known as transpiration cooling. The heated part is made of porous material, and the coolant seeps through the micropores to the heated surface, carrying away heat while forming a cooling film on the wall, providing excellent cooling effects; 3. Thermal insulation layer, where low thermal conductivity high-temperature resistant materials are applied or adhered to the heated wall to reduce heat transfer from the gas to the wall.
