What is the difference between 1.4L and 1.5L?

The difference between 1.4L and 1.5L is the displacement: 1.4L has a displacement of 1.4 liters, while 1.5L has a displacement of 1.5 liters. Both 1.4L and 1.5L are naturally aspirated engines. The engine consists of: 1. Valve train; 2. Crankshaft and connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Fuel supply system. The function of the engine is to convert the heat energy of gasoline or diesel into mechanical energy by burning the expanding gas in a sealed cylinder to push the piston. Engine maintenance items include: 1. Regularly change the engine oil and oil filter; 2. Keep the crankcase well ventilated; 3. Regularly clean the crankcase; 4. Regularly clean the fuel system; 5. Regularly maintain the radiator; 6. Maintain and clean the fuel system.

What is the removal method for the three rear spark plugs of the Buick GL8?

The removal method for the three rear spark plugs of the Buick GL8 is as follows: 1. Use a screwdriver to remove the engine cover; 2. Clean the dust and oil stains from the high-voltage wire terminals; 3. Use a socket wrench to loosen the fixing screws of the high-voltage wire terminals; 4. Use a socket wrench to loosen the spark plugs; 5. Insert the soft tube from the high-voltage wire terminal into the combustion chamber; 6. Pull out and remove the spark plugs. Taking the 2021 Buick GL8 as an example, its body dimensions are: length 5238mm, width 1878mm, height 1776mm, wheelbase 3088mm, fuel tank capacity 66L, and trunk capacity 475L.

What happens if you use 92 octane gasoline in a Volkswagen CC?

According to the official vehicle manual recommendation, the Volkswagen CC should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap of the Volkswagen CC. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade. High compression ratio engines can still be tuned to use lower octane gasoline because factors other than compression ratio, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in a Volkswagen CC, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the practical effect being poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is significantly lower, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without obvious engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
