How to Solve High Temperature Protection of Exhaust Pipe?

1 Answers

High temperature protection of the exhaust pipe is caused by excessive system air. After evacuating the system, adding refrigerant can solve the issue, and the leakage point needs to be repaired. Types of exhaust devices: Exhaust temperature protection is one type of compressor temperature protection device. Effects of excessive temperature: During compressor operation, certain factors can cause the exhaust temperature to exceed normal levels. This not only increases the compressor's power consumption but also leads to carbonization of lubricating oil, deteriorating its performance and affecting the normal operation of the compressor. To avoid excessively high exhaust temperatures, a liquid injection valve can be used to control the exhaust temperature. Main causes: Excessively high exhaust temperature is mainly caused by high return gas temperature, significant motor heating, high compression ratio, high condensation pressure, and improper refrigerant selection.

Is a 1.5t engine a 3-cylinder or 4-cylinder?

1.5t engines come in both 3-cylinder and 4-cylinder configurations. Below is how an engine works: 1. Intake stroke: The piston is driven by the crankshaft to move from top dead center to bottom dead center, while the intake valve opens and the exhaust valve closes; 2. Compression stroke: The piston moves from bottom dead center to top dead center, with both intake and exhaust valves closed; 3. Combustion expansion stroke: Both intake and exhaust valves remain closed, the spark plug ignites, and the air-fuel mixture burns intensely; Additional information: An engine is a machine that converts other forms of energy into mechanical energy. Based on working principles, engines are categorized into: external combustion engines, internal combustion engines, gas turbines, and jet engines.

What Causes the Electronic Parking Brake Warning Light to Illuminate in the Vezel?

Introduction to the reasons why the electronic parking brake warning light illuminates in the Vezel: 1. The parking brake is not fully released: You can pull the parking brake and release it again to see if the light turns off. 2. Brake fluid leakage: You can go to a repair shop or 4S store to check and fix the brake fluid leakage position, then replenish the brake fluid. These two lights will turn off and return to normal. 3. Brake pads thinning: This causes the brake fluid level in the reservoir to drop. When it drops to the point where the brake fluid level sensor is activated, the parking brake light will illuminate. However, when the fluid level is just at the threshold of activation, the parking brake light may flicker on and off as the vehicle moves.

Should You Press the Clutch or Brake First When Starting on a Slope?

When starting on a slope, you should press the brake first and then the clutch. If you press the clutch first, the car will be in neutral, losing engine control and causing it to roll backward. Therefore, when starting on a slope, you should press the brake first and then the clutch. Here is some relevant information about the clutch: 1. Introduction: The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. 2. Friction Clutch: The friction clutch is the most widely used and historically oldest type of clutch. It basically consists of four parts: the driving part, the driven part, the pressing mechanism, and the operating mechanism.

Which Gear Should Be Used for Curve Driving?

For curve driving in Subject 2 of the driving test, use second gear. Below is relevant information about vehicle gear shifting: Precautions: When downshifting, the method of double-clutching plus a blip of the throttle should be used. The principle of downshifting with a throttle blip is: the faster the speed, the larger the "throttle blip"; the slower the speed, the smaller the "throttle blip". At low engine speeds, the "throttle blip" should be larger; at high speeds, it should be smaller. On flat roads, the "throttle blip" should be larger; when going uphill, it should be smaller. Techniques: Gear shifting should be timely, accurate, smooth, and quick. When starting the car, generally use the low gear (first gear). After starting, as long as road conditions permit, shift up to higher gears promptly and progressively.
