What is the firing order of a four-cylinder engine?

The firing order of a four-cylinder engine can be either 1-2-4-3 or 1-3-4-2, depending on factors such as the crankshaft structure. Here is some relevant information: 1. Working cycle: The working cycle of a four-stroke gasoline engine consists of four piston strokes, namely the intake stroke, compression stroke, power stroke, and exhaust stroke. Currently, all internal combustion engines used are four-stroke engines. The four strokes refer to one working cycle, where the piston moves up and down four times to complete the intake, compression, power, and exhaust processes. 2. Crankshaft: The crankshaft is an important component in a car engine. Its function is to convert the gas force transmitted by the piston and connecting rod into torque, transforming the linear motion of the piston into rotational motion, which is used to drive the car's transmission system, the engine's valve train, and other auxiliary devices.

Where is the Tire Pressure Monitoring in the Sylphy?

The tire pressure indicator of the Sylphy can be viewed on the instrument display screen, which directly shows the specific values of all four tires. According to the requirements and regulations of the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the completion of the tire pressure reset.

What is the normal antifreeze level for Mercedes-Benz?

The normal antifreeze level for Mercedes-Benz is when the coolant level is above the fill line mark. If the level is too low, please add antifreeze coolant. Coolant level: The Mercedes GLC coolant reservoir will have water level markings. Under normal conditions: if the cooling system is cold, the coolant level should be above the fill line mark. If the level is too low, please add antifreeze coolant. Before opening the filler cap, let the engine cool down. To add coolant, use a mixture of diluted coolant concentrate and clean tap water in a 1:1 ratio. Function of antifreeze: Antifreeze, also known as antifreeze coolant, is a coolant with antifreeze properties. The engine generates a lot of heat during operation and needs to be cooled. Antifreeze is the circulating fluid used in the engine cooling system. Therefore, antifreeze is mainly used to dissipate heat from the powertrain.

Where is the production date located on a Fengfan battery?

Fengfan battery production date is composed of a series of Arabic numerals and English letters, located on the surface of the battery. The production date of a car battery plays a decisive role in checking the aging degree of the battery. The production date of the battery needs to be interpreted according to the manufacturer's coding method. For example, a Fengfan battery labeled as 4A0735331 indicates that '4' represents the year 2014, 'A' represents January, 'B' represents February, and so on, while '07' stands for the 7th day of the month. In summary, this battery was produced on January 7, 2014. As for the remaining '35331' identifier, it refers to the production unit code and team serial number. It is best to purchase batteries from official channels, as there are some small factories in the market that recycle old batteries. The production dates marked on such batteries are basically unreliable, with no good quality assurance, and lacking overvoltage and overcurrent protection, posing certain safety hazards during charging.
