The normal high pressure for the BYD e5 air conditioning system should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); the normal low pressure should be between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). If the low pressure is higher or lower than this range, it indicates that the expansion valve adjustment is abnormal. Issues with the compressor are not included in this category. Below is an introduction to the normal pressure range for car air conditioning: 1. Normal conditions: The normal high pressure for car air conditioning should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); the normal low pressure should be between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). If the low pressure is higher or lower than this range, it indicates that the expansion valve adjustment is abnormal. Issues with the compressor are not included in this category. 2. At idle speed: If the ambient temperature is high, such as under direct sunlight in summer, the high pressure might be slightly higher, up to around 2.5~2.8MPa, but it generally does not exceed 3.1MPa, otherwise the pressure switch will activate the protection function.

Will the Engine Stall If I Brake in Second Gear Without Depressing the Clutch?

Braking in second gear without depressing the clutch will cause the engine to stall because the car's clutch does not fully disengage, leading to stalling. Below are specific details about the clutch: Location: 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. Function: During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transferring the engine's power input to the transmission. Role: The clutch is a common component in mechanical transmission systems, allowing the drivetrain to be separated or engaged at any time.

How many days does it take to check traffic violations?

Traffic violations can usually be checked within 2 to 5 working days. Here is relevant information: Relevant laws: According to Article 19 of the "Procedures for the Handling of Road Traffic Safety Violations" issued on April 30, 2004, within ten days from the date when the traffic technical monitoring equipment collects the violation records, the traffic management department of the public security organ at the place where the violation occurred shall review the recorded content. After verification, it will be entered into the road traffic violation information management system as evidence of the violation. Notes: For local violations, the records can generally be found on the traffic violation inquiry website within a week. For out-of-town violations, it may take 2~3 weeks to check. It is best to inquire about out-of-town violations on the traffic website where the violation occurred.

What does it mean to add urea to a diesel vehicle?

Adding urea to a diesel vehicle is a process aimed at meeting emission standards. Below are specific details about urea: Introduction: The primary harmful substances in diesel vehicle exhaust are nitrogen oxides and particulates. Technical measures within the engine can reduce particulate emissions, leaving nitrogen oxides as the main component in the exhaust. Urea is injected into the exhaust after-treatment device, where it decomposes into ammonia at high temperatures. In the presence of a catalyst, the ammonia reacts with nitrogen oxides. Purpose: Adding urea helps reduce nitrogen oxide compounds in the exhaust, lowering emission pollution and making the vehicle more environmentally friendly. Currently, most diesel engines employ Selective Catalytic Reduction (SCR) technology. The general principle is that after the engine exhaust exits the turbocharger, it flows directly into the exhaust pipe and passes through a catalytic converter. A urea nozzle on the exhaust pipe then sprays a urea aqueous solution under computer control. This solution reacts with nitrogen oxides in the exhaust within the SCR catalytic converter through redox reactions, ultimately converting the exhaust into nitrogen gas and water before being released.

What is the normal pressure difference between four tires?

The normal pressure difference between four tires should be within 0.1bar. However, it is not necessary to adjust immediately if the difference exceeds 0.1bar, as the error in tire pressure monitoring and different vehicle load conditions may temporarily cause variations in tire pressure. Tire pressure monitoring is a system that automatically and continuously monitors the air pressure in tires while driving, alerting the driver to leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct TPMS: Direct TPMS uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the data for each tire. The system automatically alerts the driver when the tire pressure is too low or there is a leak. Indirect TPMS: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius of tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of both the above systems. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a full direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data of the actual pressure in all four tires as a direct system does.

Why does the car's idle speed fluctuate up and down?

The fluctuating idle speed of a car is caused by a faulty carbon canister, and replacing the car's carbon canister can resolve the issue. Below are specific details about the car's carbon canister: Installation and Function: It is installed between the fuel tank and the engine, utilizing the adsorption capability of its internal activated charcoal to absorb and store gasoline vapors from the fuel tank. Working Principle: When the engine starts, the solenoid valve between the activated charcoal canister and the intake manifold opens according to the ECU's command. At this point, the gasoline vapors inside the activated charcoal canister are drawn into the cylinder along with the air under the vacuum pressure of the intake pipe to participate in combustion. This not only reduces unnecessary emissions but also lowers the engine's fuel consumption.
