4-piston caliper refers to a brake caliper that has four hydraulic pistons in operation. The more pistons a brake caliper has, the greater and more stable the braking force it generates. Related information is as follows: 1. Introduction to brake calipers: It refers to a clamping device that functions to decelerate, stop, or maintain the stopped state of moving wheels, generally used only in disc brake systems. 2. Components of disc brakes: Consisting of a brake oil pump, a brake disc connected to the wheel, and the brake caliper on the disc. When braking, high-pressure brake oil pushes the pistons inside the caliper, pressing the brake pads against the brake disc to produce the braking effect. Disc brakes are divided into two types: ordinary disc brakes and ventilated disc brakes.

What's the difference between 24v and 48v?

Taking lead-acid maintenance-free batteries for electric vehicles as an example, different voltages correspond to different numbers of batteries. The following are the differences between the two: 1. Voltage: The rated voltage of the former's pull-in coil is DC 48v, while the latter's is DC 24v. 2. Contact: The contacts of the former allow a current of 10A under 220v AC, the same as the latter under the same voltage, meaning the former's contact capacity is slightly larger than the latter's, at 2420VA. 3. Practical selection: Consider whether the contact capacity matches the actual needs and whether the control voltage matches the rated value of the relay's pull-in coil. If a 24v current is used to control a relay with a 48v pull-in coil, issues such as failure to pull in or insecure pull-in may occur.

What are the reasons for a diesel engine suddenly stalling?

The reasons for a diesel engine suddenly stalling are as follows: 1. Poor operation of the low-pressure fuel system: Before stalling, the diesel engine's speed gradually decreases, but the engine sound remains normal, and the exhaust gas color shows no abnormalities, yet it can still lead to sudden stalling. 2. Presence of water in the diesel fuel: This may cause the diesel engine's speed to become unstable before stalling, with white smoke coming from the exhaust pipe, leading to sudden stalling during operation. 3. Damaged cylinder head gasket: If the diesel engine continues to emit white smoke and stalls or fails to start after removing water, the cylinder head gasket may need to be replaced before testing the engine again.

How far can you drive with a flat tire?

Run-flat tires can still be driven for a certain distance after a puncture, while regular tires cannot continue to be driven. Below are some methods to prevent tire blowouts: 1. Regularly check tire conditions: Inspect tire pressure, observe if the tire sidewalls are cracked, and monitor tread wear. 2. Install a tire pressure monitoring system: The device will automatically alert you when tire pressure is abnormal, preventing blowouts. 3. Apply puncture-proof treatment to tires: Spray a protective film on the inner wall of the tire to prevent punctures and air leaks when encountering sharp objects. 4. Rotate tires periodically: This helps ensure even tire wear and avoids using tires of different models or with significant wear differences on the same axle. 5. Regularly correct wheel balance: Severe imbalance can cause high-frequency vibrations at high speeds, leading to uneven tire wear and compromising driving safety. After tire repairs, promptly perform balance checks and adjustments.
