What Causes Overly Rich Air-Fuel Mixture in Cars?

Reasons for overly rich air-fuel mixture in cars: 1. Idle speed, engine meeting torque requirements leading to overly rich mixture; 2. Oxygen sensor failure; 3. Inaccurate air intake measurement - check for fuel injector leakage and the working performance of the fuel pressure regulator, as poor performance can also cause an overly rich mixture. The air-fuel mixture in cars refers to the combination of fuel and air, typically gasoline, diesel, etc. mixed with air. However, with advancements in automotive technology and fuel diversity, it now also includes mixtures with various combustible gases such as natural gas, methane, coal gas, as well as ethanol, methanol, and other mixtures.

What is the difference between low-end torque and high-end torque?

The difference between low-end torque and high-end torque lies in the fact that the maximum power occurs at different RPM ranges. Below is a detailed introduction to the differences between the two: 1. Power aspect: The power is relatively small, and as the RPM increases, the power gradually amplifies. With further RPM increase, the power will slowly decline. A car with high torque at low RPM means it can output relatively high torque at lower RPMs, while a car with low torque at high RPM means it outputs relatively low torque at higher RPMs. 2. Engine internal structure aspect: Gasoline engines belong to the high RPM category, whereas diesel engines belong to the low RPM category.

How to Use the 8th Generation Camry's Manual-Automatic Transmission?

8th Generation Camry's manual-automatic transmission is specifically used by switching from P gear to D gear, and then from D gear to the left M gear. Pushing up shifts to a higher gear, while pushing down shifts to a lower gear. Below is more information about the manual-automatic transmission: 1. The manual-automatic transmission is also a type of automatic transmission, but it adds the function of manual shifting. 2. The driver controls the shifting timing based on the engine speed and actual road conditions. 3. In manual mode, when the vehicle brakes or decelerates, the transmission will automatically downshift, and the driver does not need to manually downshift unless encountering situations that require forced downshifting, such as accelerating to overtake.

What Causes Doors to Automatically Lock?

The reason doors automatically lock is that when the vehicle speed reaches the preset value in the computer, the door lock button will be automatically pressed. This feature, also known as speed-sensing auto-locking, is designed to prevent accidental door opening. There are other methods of automatic door locking as well. For instance, when the transmission is shifted into D (Drive) gear, the lock button will automatically engage to prevent unintended door opening. Some Chevrolet and Buick models use this locking method. Another method involves the doors automatically locking when the driver applies the brakes during driving, commonly found in domestic or some low-end vehicles. A less common locking method is when the doors automatically lock after the vehicle has been in continuous motion for 10 seconds.

What Causes the Exhaust Pipe to Turn Red?

Exhaust pipes turning red occur when part of the combustible gas from the cylinders enters the exhaust pipe and continues to burn. The specific reasons are as follows: Combustible gases rushing into the exhaust pipe: This leads to the exhaust gases entering the exhaust pipe, raising the exhaust temperature. If the fuel injection timing is too late, it not only slows down the combustion rate but also results in incomplete combustion, causing diesel to burn in the exhaust pipe during the later stages of injection, thereby increasing the exhaust temperature. Part of the combustible gas from the cylinders enters the exhaust pipe: An overly lean air-fuel mixture can cause slow combustion after ignition, extending into the exhaust stroke and continuing to burn. Exhaust valve leakage or insufficient valve clearance: If the exhaust valve does not seal properly or the valve clearance is too small, it allows combustion gases to enter the exhaust pipe, raising the exhaust pipe temperature.
