What is the fuel tank capacity of the Changan CS55 in liters?

The fuel tank capacity of the Changan CS55 is 58L. More relevant information is as follows: 1. The fuel tank is a container for storing fuel in a vehicle: it is a specialized container in the hydraulic system for storing hydraulic oil or hydraulic fluid. 2. Fuel tanks are divided into two types: open tanks and closed tanks. The fuel tank must have a sufficiently large volume; the suction pipe and return pipe should be inserted below the lowest liquid level to prevent air suction and splashing of return oil, which can create bubbles. The distance between the suction pipe and return pipe should be as far apart as possible, with a partition set up between them. 3. To maintain clean oil: the fuel tank should have a sealed cover plate around its perimeter, equipped with an air filter; the bottom of the fuel tank should be at least 150mm above the ground; special attention should be paid to the anti-corrosion treatment of the inner surface of the fuel tank. In addition to storing oil, the fuel tank in the hydraulic system also plays roles in heat dissipation, separating bubbles from the oil, and precipitating impurities. Many auxiliary components are installed in the fuel tank, such as coolers, heaters, air filters, and liquid level gauges.

Where are the 10 speakers located in the Haval Big Dog?

There is one center speaker in the front row, one on each A-pillar, one on each front door, two on each rear door, and a subwoofer in the trunk or on the left side of the third row, totaling 10 speakers. Below is relevant information: 1. Function: The horn is the audio signal device of a car. During driving, the driver emits necessary audio signals as required and regulated to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. 2. Working Principle: The car electric horn produces sound through the vibration of a metal diaphragm. It consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that pulls the armature, forcing the diaphragm to move. The armature movement opens the contacts, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, aided by its own elasticity and spring, returns to its original position with the armature, closing the contacts and reconnecting the circuit. Current flows through the contacts to the coil again, generating magnetic force and repeating the process. This cycle causes continuous vibration of the diaphragm, producing sound. The resonance board, rigidly connected to the diaphragm, ensures smooth vibration and more pleasant sound (i.e., the principle of electromagnetism).
