Below are the detailed reasons for the phenomenon of braking deviation in automotive air pressure braking systems: 1. Inconsistent tire pressure between the left and right wheels. 2. Inconsistent braking clearance between the left and right wheels. 3. Inconsistent contact area between the brake shoes and brake drums of the left and right wheels. 4. Water or oil contamination in the brake system of one front wheel. 5. Severe deformation or grooving of the brake drum on one front wheel. Braking deviation mainly manifests in the following two forms: 1. The vehicle deviates from its intended direction during braking while driving. 2. During emergency braking, the direction suddenly changes or the vehicle fishtails.

Brake deviation in air brake systems is usually caused by an imbalance in braking force between the left and right sides. From my research on trucks, the main reasons include uneven wear of brake drums or brake linings on both sides, leading to uneven force distribution when air pressure is too high or too low; improper adjustment of the air chamber push rod, such as rust or sticking, causing one side to brake more aggressively; air leaks or blockages in the air lines, resulting in uneven air distribution; suspension issues like loose shock absorbers or deformed linkages affecting wheel alignment; and brake chamber failures, such as diaphragm rupture, creating excessive pressure differences between the left and right sides. In such cases, it's essential to use a pressure gauge to check line pressure and troubleshoot each issue individually to prevent further damage. Proper maintenance can save a lot of trouble, so I always remind technicians to check these points during every service.

What is the difference between dual CVTC and ECVT?

The differences between dual CVTC and ECVT are as follows: 1. Dual CVTC: Dual CVTC is a variable valve timing system, which is a technology used in automotive piston engines. The variable valve timing system consists of solenoid valves and variable camshaft phase adjusters. By adjusting the camshaft phase of the engine, the intake volume can change with the engine speed, thereby achieving optimal combustion efficiency and improving fuel economy. The variable valve timing system can not only change the opening and closing times of the intake and exhaust valves but also enhance power output to some extent. Its principle involves using hydraulic action to alter the angle between the camshaft synchronous timing belt pulley and the end of the camshaft, thus changing the valve timing angle. 2. ECVT: ECVT can only be used in motor-driven or hybrid vehicles and is not applicable to gasoline engines. It adjusts speed through the motor, features an all-gear structure, can withstand greater torque, and offers higher efficiency and faster speed.

What is the CRDI car?

Honda CRider is actually the Honda Lingpai. The Honda Lingpai is a new strategic mid-size sedan under GAC Honda, specifically designed by GAC Honda to meet the comprehensive needs of post-80s consumers as a mainstream compact car. Here are the detailed specifications: 1. Powertrain: It is equipped with a brand-new 1.0t inline three-cylinder engine with the code name P10A3. This engine delivers a maximum power of 122 horsepower and a peak torque of 173 Nm. The transmission system is paired with either a six-speed manual or a CVT continuously variable transmission. 2. Features: In the mid-to-high trim levels of the new Lingpai, a 7-inch multimedia display is provided, integrating functions such as Bluetooth telephony, audio system, and vehicle information.

What are the reasons for the abnormal noise in the rear brake of the UY125?

The reasons for the abnormal noise in the rear brake of the UY125 are as follows: 1. Break-in period for new vehicles: New vehicles or recently replaced brake discs and pads will have a break-in period, during which some abnormal noises are unavoidable. These noises typically disappear after driving a few hundred kilometers. 2. Normal activation of the ABS system: During emergency braking, the brake pedal may produce a continuous "thudding" sound, sometimes accompanied by a pulsating sensation. This indicates that the ABS system is activated, which is normal. In such cases, firmly press the brake pedal all the way down, but this applies only to vehicles equipped with an ABS system. 3. Metal hard spots on the brake pads: Brake pads may contain small metal particles, which can produce sharp, screeching noises when lightly braking. This issue can be resolved by forcefully applying the brakes several times, removing and regrinding the brake pads, or replacing them with higher-quality ones. 4. Severe wear on the brake disc: Wear on the brake disc can create deep grooves around its circumference. Friction between the brake pads and the edges of these grooves can cause abnormal noises. If the grooves are not too deep, grinding the edges of the brake pads to avoid contact with the groove edges may solve the problem. If the grooves are very deep, replacing the brake disc is necessary. Generally, it is recommended to replace the brake disc every two brake pad replacements.

What lights to use when going straight through an intersection without traffic signals?

When passing through an intersection without traffic signals, you should alternately use high and low beams more than twice, slow down in advance, and signal by alternating between high and low beams while paying close attention to the traffic ahead. At night when approaching an uncontrolled intersection, switch between low and high beams near the intersection to alert vehicles and pedestrians from perpendicular directions and opposite lanes, while also reducing your speed. Below are related lighting instructions: 1. Driving at night without streetlights or under poor lighting conditions (headlights). 2. Meeting non-motor vehicles on narrow roads at night (low beam). 3. Following another vehicle closely in the same direction at night (low beam). 4. Meeting motor vehicles at night (low beam). 5. Passing over bridges or crosswalks at night (alternate between high and low beams). 6. Navigating sharp curves or slopes at night (alternate between high and low beams). 7. Passing through intersections without traffic signals at night (alternate between high and low beams). 8. Experiencing a vehicle breakdown on the road at night that obstructs traffic and is difficult to move (parking lights and hazard warning lights). 9. Driving in foggy conditions (fog lights and hazard warning lights).

What are the reasons for the Nissan Qashqai's inability to accelerate without fault codes?

Nissan Qashqai's inability to accelerate without fault codes may be due to spark plug erosion or a dirty air filter causing poor air intake. Below is relevant information about the Qashqai: 1.

Handling: The overall driving experience is quiet and comfortable. The high seating position provides a broad field of vision. The steering wheel offers clear direction, is light to turn, and has moderate resistance. The chassis is solid, with high ground clearance and strong off-road capability, along with good high-speed stability. The brakes are responsive, and the sound insulation is effective.

How Many More Years Can China III Gasoline Private Cars Be Driven?

China III vehicles are highly likely to be phased out. Although mandatory scrapping has not been enforced, they are facing guided scrapping. Restricted driving zones are increasing, with cities like Beijing and Shenzhen successively announcing restricted areas for China III vehicles. Additional information is as follows: 1. China III Standard: This refers to China's third-stage vehicle emission standards. The main requirements are: HC emissions below 0.2g/km, CO emissions below 2.3g/km, NOx emissions below 0.15g/km, with no PM requirement. 2. Vehicle Exhaust: Vehicle exhaust contains carbon monoxide, nitrogen oxides, and other solid particles harmful to human health, especially leaded gasoline, which poses greater risks. Lead in exhaust exists in particle form and spreads with the wind. Vehicle exhaust is highly complex, with over 100 components, and its main pollutants include carbon monoxide, hydrocarbons, and nitrogen oxides. 3. Gasoline Composition: Gasoline is primarily composed of carbon and hydrogen. During normal combustion, it produces carbon dioxide, water vapor, and excess oxygen, among other substances. However, due to impurities and additives in the fuel and incomplete combustion, harmful substances are often emitted.
