⚙Differential

⚙Differential When a car is going straight, the left and right wheels rotate at the same speed. Rotation rate is usually expressed in rpm (revolutions per minute). rpm tells you how many revolutions per minute. At 500rpm, it is considered to be 500 revolutions per minute. Larger generators run at 1500rpm to produce a frequency of 50Hz. Excavator side panels work at 1800rpm. The left and right wheels rotate at the same speed as the car is moving When turning, the left and right wheels do not rotate at the same speed. When turning left, the left wheel spins slowly and the right wheel spins fast. When you turn right, the right wheel slows down and the left wheel spins fast. If both left and right wheels rotate at the same rpm, there is no way to turn. Due to this, it is not possible to connect the left and right wheels with the same shaft. Let me give you an example of a rear-wheel-drive car. In the rear seat, the front wheel is not connected to the engine. The power of the engine is...

Four wheel drive (4WD)

Four-wheel drive system ( 4WD ) 


Four wheel drive (4WD) is generally the all wheel drive (AWD) system. It was started in the late 1920s, and during World War II, Jeep-type off-road military trucks were especially popular because of the 4WD.
4WD engines were also used in front engines and mid engines, especially in pickups and light trucks.



In addition, the most powerful of the AWD, FWD, RWD of the car is the AWD, and the four-wheel drive in the starting condition makes the traction better than other FWD, RWD. Also, the 4WD and AWD mentioned above seem to be pretty much the same, but the only difference is that the 4WD is a four-wheel drive system that only allows the car to operate when needed, and can only be driven with 2WD when not needed.


Here are some of the highlights of 4WD:
Part time: 4WD is a system that only works when needed. It is often used in off-road vehicles, and when the car's tires are slippery and can not be driven at the same time, the four-wheel drive system's slow torque is called 4WD part time because it is not a permanent system. How it works: As soon as the driver presses the 4WD switch, it starts working.

Full time: How it works is now called AWD. In addition, both on-road and off-road are included, and all four wheels will rotate at the same speed. Its structure is that the differential is centered and all back and forth are alike.


On demand: It involves an electronic system that only works in slippery conditions as the car automatically detects.

About Oxygen Sensor

About Oxygen Sensor This time, I would like to talk about the oxygen sensor O2 sensor. As technology advances, sensors are being installed all over the car to sense the sensitivity of each car. So the O2 sensor here is called the O2 sensor. Of the many sensors used only in oxygen cars, the O2 sensor plays a very important role. Here's what the O2 sensor oxygen sensor is used for The O2 sensor in the exhaust manifold exhaust installed near the Max value after processing engine exhaust air through the exhaust vapors into what eventually ventured into developed the O2 sensor into the exhaust in the exhaust fumes from the fire and there is much in excess of the amount of oxygen sensor has the ability to measure the amount of oxygen from the exhaust sensor if the engine oil and the ratio required to check testosterone was applied to average the wrong O2 sensor to measure the ratio of the mixture onto the low oxygen ညး exact way any computer box ECU This is a function of the O2 sensor Ho...
