No, engine oil requires a combustible material to ignite. Under normal circumstances, engine oil will not burn when exposed to an open flame without any attached combustible material. However, engine oil itself is flammable, so if there is an attached combustible material carrying an open flame, it can catch fire. Therefore, for safety reasons, it is best to avoid exposing engine oil to open flames. Additionally, storage should be handled with care, and contact between engine oil and open flames should be minimized. The boiling point of engine oil is generally around 150°C, and its flash point should be 20–30°C higher than its operating temperature. The choice of engine oil should be based on the operating temperature, as not all vehicle models operate under the same conditions.

How to adjust the timing for a Chevrolet Cruze?

Steps to adjust the timing for a Chevrolet Cruze: 1. Lift the vehicle, remove the right front wheel, and take off the generator belt, engine rubber mount, and timing cover. 2. Rotate the crankshaft to align the mark on the crankshaft pulley with the mark on the housing. 3. For the camshaft marks, use a special tool to lock the position between the two camshafts, then use a hex wrench to turn the tensioner and remove the timing belt. 4. Install the new belt and tensioner, then reassemble in the reverse order of disassembly. 5. The belt has low noise, minimal self-deformation, and is easy to compensate for. The belt's lifespan is certainly shorter than metal gears, so it should be replaced regularly.

Can a Water-Damaged Car Key Be Repaired?

Water-damaged car keys can be repaired, but whether to repair or replace the key depends on the extent of damage to the key's circuit board. Below are some details about car key repair: 1. When a car key is damaged by water, the internal circuit board is usually short-circuited. 2. The circuit board contains many electronic components, and during repair, detailed measurements are required to determine the extent of the damage. If the damage is not severe, the key can be repaired. 3. If the damage is severe and the circuit board is completely burnt, repair is no longer a viable option.

What is the fuel tank capacity of the Changan Oshan X7 in liters?

The fuel tank capacity of the Changan Oshan X7 is 55 liters, as officially announced. Owners who have purchased the Changan Oshan X7 can also check this information on the vehicle's configuration sheet. The Changan Oshan X7 requires 92-octane gasoline, with a fuel consumption of 7-7.4L per 100 kilometers. A full tank can cover a distance of approximately 743 to 786 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, with additional space from the safe fill level to the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Can Plug-in Hybrid Vehicles Operate Without Charging?

Plug-in hybrid vehicles cannot operate without charging. The specific reasons are as follows: 1. Plug-in hybrid vehicles have two power drive systems: one is a traditional internal combustion engine drive, which consumes fuel (gasoline or diesel) to obtain driving force; the other is an electric drive, which consumes the power stored in the battery to obtain driving force. Under certain conditions, the two systems can work together to drive the vehicle. 2. Under normal circumstances, the engine of a plug-in hybrid vehicle cannot directly charge the power battery, but it can charge the battery through some energy recovery devices. Therefore, when the power battery is low on charge, it must be charged externally. In other words, plug-in hybrids must be charged.
