Engine instructions

1. Car engine - Car engines are the heart parts of cars, and their size can be expressed by displacement (liters); according to the fuel used, they can be divided into gasoline engines and diesel engines; according to the working process It can be divided into four-stroke and two-stroke; according to the cooling method, it can be divided into air-cooled and water-cooled.

2. Kaiyue engine is divided into 1 cylinder, 2 cylinders,The position of 3-cylinder and 4-cylinder: from left to right, 1-cylinder, 4-cylinder, 2-cylinder and 3-cylinder respectively (as shown in the figure). Cylinder wire change method: Before replacing the cylinder pipe, a hexagonal socket wrench should be prepared. Stop the car, tighten the handbrake, pull out the key, and disconnect the battery cathode.

3. Fuel brand (RON) No. 90 or above gasoline (SH0041) closed-loop control engine must use unleaded gasoline.

Hyunyuedong engine compartment illustration

Hyunyuedong engine cover detailed explanation shows that the automobile engine cooling circulation water secondary storage tank heat pipe radiator cover brake system oil/clutch oil storage tank ( Only DOT3 or DOT4 brake system oil/clutch oil from sealed vessels is applied. Regularly maintain the remaining oil in the oil storage tank.

Hyundai Yuedong engine compartment illustration engine cooling water secondary water tank radiator cover brake fluid/clutch oil storage tank (only DOT3 or DOT4 brake fluid/clutch oil from the sealed container is used. Check the amount of oil in the oil storage tank regularly. The amount of oil should be between the MAX and MIN marks on the side of the oil storage tank.

Pull up the engine compartment cover handle, and the engine compartment cover will bounce up slightly;Reach into the central position of the front end of the engine hatch, touch the auxiliary hook handle of the engine hatch, lift the paddle up and hold it, and lift the engine hatch up at the same time.

Air compressor adjustment: The evaporated refrigerant is compressed into liquid, and then pumped into the evaporator to produce the cooling we need~! Exhaust manifold: The exhaust gas from each cylinder of the engine flows into the exhaust manifold through the exhaust manifold, and then discharged into the atmosphere through the ternary catalytic converter and silencer.

The Hyundai Yuedong fuse box is located in the engine compartment and the driver's seat side fuse box. The name and location instructions of the fuse can be found on the inside of the fuse/relay box cover. Turn off the engine and all other switches. All switches are placed in the OFF position. Remove the fuse box cover by pressing the tongue and pulling up.

There are many fuses and relays for electrical equipment in it.F 1 has two fuse boxes, and the other is at the bottom left of the driver in the cab. Please check the specific on-board instructions. Air intake: The air intake of the engine has been optimized, and its position has also been improved a lot.

Some dry knowledge about automobile generators and batteries

1. Automobile generators can also charge batteries at idle speed, but the charging current is relatively small. Moreover, the output voltage of automobile generators is about 14V-16V. While driving, cars use the electricity of the generator, and the greater the power consumption, the greater the running resistance of the generator, which indirectly affects the fuel consumption, so do not turn on too much electrical equipment when unnecessary.

2. Because the electricity of the car batteryThe pressure depends on the difference in the material of the pole plate and the concentration of the electrolyte, so after the discharge reaction, the car battery loses energy. The charging process is the opposite of the discharge process.

3. PHEV is the abbreviation of "Plug-in Hybrid Electric vehicle" in English, which is a plug-in hybrid vehicle on the market. PHEV can switch between pure electric mode and pure fuel mode at will, and even the motor and fuel engine can operate at the same time to hybridly provide power.

4. Let the generator continue to supply power to the electrical appliances in the car. Turn off all electrical switches in the car before turning off the engine to prevent increasing the battery load when starting the engine again. In addition, if the vehicle is not used for a long time, it is better to start the car a week, let the engine run for more than ten minutes, and let the generator charge the battery to maintain the battery storage capacity.

5. The battery of the car is out of power. I believe that there will be such a situation, that is, the car suddenly can't start. There are many reasons why the car can't start. The more common ones are starter failure, gasoline pump failure, generator failure, battery failure, etc. The above is that the car can't start. The cause and solution of the fire.

6. If the car battery is short of water, first of all, it should be determined whether the liquid in the battery has evaporated. When the battery is discharged, the concentration and specific gravity of sulfuric acid of the electrolyte will drop. After complete discharge, of course, the most accurate way is to measure the concentration of electrolyte with a specific gravity meter.
