Can 95 and 92 Octane Gasoline Be Mixed Together?

What are the causes of long-term fuel trim being too high?

The reasons for long-term fuel trim being too high are: 1. Clogged fuel injectors and poor spark plug combustion; 2. Poor quality gasoline; 3. Measurement deviation of the air flow meter and air leakage; 4. Long-term failure to replace the fuel filter, resulting in low fuel pressure; 5. Oxygen sensor detecting excessively high oxygen content. The suitable range for long-term fuel trim is between -23% and 16%. The following factors affect the fuel trim coefficient: 1. Engine misfire: When the engine misfires, incomplete combustion occurs in the cylinder, leading to high levels of HC and O2 in the exhaust. Since HC does not easily participate in catalytic reactions, oxygen consumption is low, and residual oxygen levels are high, causing the oxygen sensor to measure a lower voltage, indicating a lean mixture. The ECU then increases fuel injection, making the short-term fuel trim correction value positive. 2. Poor exhaust flow: A clogged exhaust pipe obstructs the discharge of exhaust gases, manifesting as excessive backpressure and reduced intake of fresh air into the cylinders. This results in incomplete combustion of the mixture, with the oxygen sensor voltage exceeding 0.45V, and the fuel trim coefficient becoming negative. 3. Low fuel pump pressure or clogged fuel injectors: Clogged fuel injectors cause symptoms such as sluggish acceleration and lack of power at high speeds. The engine remains in a lean mixture state.

How to Solve Timing Belt Noise?

Timing belt noise can be resolved by: 1. Determining whether the noise is caused by the belt itself or by damaged timing belt tensioner/idler pulleys; 2. Inspecting both sides of the timing belt for fine cracks - replacement is necessary if found; 3. Adjusting the belt tensioner if the vehicle has low mileage and the belt shows no cracks; 4. Checking the tensioner pulley - replace any faulty pulley causing noise. The timing belt is a critical component of the engine's valve timing system, connecting to the crankshaft with specific gear ratios to ensure precise intake/exhaust valve timing.

What Causes a Car to Fail to Start After Stalling?

There are several reasons why a car may fail to start after stalling: 1. Battery malfunction: A depleted car battery can cause the vehicle to fail to start after stalling. If the battery remains undercharged for an extended period, its lifespan will be significantly reduced. 2. Spark plug failure: Issues such as clogged spark plugs can also prevent the car from starting. Spark plugs function by discharging high-voltage pulses from the ignition coil, creating an electric spark that ignites the air-fuel mixture in the combustion chamber. If clogged, the car cannot be started. 3. Fuel pump failure: After prolonged use, the fuel pump may experience significant wear, leading to insufficient fuel supply.

Do You Need to Press the Clutch When Making a U-Turn in a Car?

You do not need to press the clutch when making a U-turn in a car, because you need to use the semi-engagement technique when starting. At this time, the speed difference between the clutch plate and the engine flywheel is too large. If you suddenly release the clutch pedal, it will cause the engine to stall. The clutch is a component found in all manual transmission cars. Manual transmission cars have a clutch pedal in the cabin. The function of the clutch is to connect or disconnect the engine from the transmission. When the clutch pedal is pressed, the connection between the engine and the transmission is disconnected. When the clutch pedal is released, the engine and the transmission will be connected.
