⚙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...

The answer is as to why car tires open on the highway

”The answer is as to why car tires open on the highway.
Every car driver should know “




It has been reported for a long time that car tires are often open on the Yangon-Nay Pyi Taw Expressway, initially because the road is a concrete road.

I think it's easy. Later, I remembered what I read while changing my car tires and shared it with my friends

First of all, let's look at the numbers written on the side of the tire. For example, let's say P195 / 60R15 87S…

The numbers on the front indicate the tire size, and the latest 87S is important for safety.

Load…..lbs………KGs…|…..Load……lbs……….KGs

71…….761……..345…|…..91………1356……..615

72…….783……..355…|…..92………1389……..630

73…….805……..365…|…..93………1433……..650

74…….827……..375…|…..94………1477……..670

75…….853……..387…|…..95………1521……..690

76…….882……..400…|…..96………1565……..710

77…….908……..412…|…..97………1609……..730

78…….937……..425…|…..98………1653……..750

79…….963……..437…|…..99………1709……..775

80…….992……..450…|…..100……..1764……..800

81…….1019…….462…|…..101……..1819……..825

82…….1047…….475…|…..102……..1874……..850

83…….1074…….487…|…..103……..1929……..875

84…….1102…….500…|…..104……..1984……..900

85…….1135…….515…|…..105……..2039……..925

86…….1168…….530…|…..106……..2094……..950

87…….1201…….545…|…..107……..2149……..975

88…….1235…….560…|…..108……..2205……..1000

89…….1279…….580…|…..109……..2271……..1030

90…….1323…….600…|…..110……..2337……..1060

On the Yangon-Nay Pyi Taw Expressway, car tires are often open, and even more important is the speed limit.

Starting in 1991, the tire speed limit was consistently expressed in the same way as above. For example, in the case of the P195 / 60R15 87S.

. According to the latest letter S, the top speed of this tire is 112 mph (180 km / h).

The table below shows the maximum tire speed of the tires.
L 75 mph 120 km/h Off-Road & Light Truck Tires

M 81 mph 130 km/h Temporary Spare Tires

N 87 mph 140km/h

P 93 mph 150 km/h

Q 99 mph 160 km/h Studless & Studdable Winter Tires

R 106 mph 170 km/h H.D. Light Truck Tires

S 112 mph 180 km/h Family Sedans & Vans <<< from Example Above T 118 mph 190 km/h Family Sedans & Vans U 124 mph 200 km/h H 130 mph 210 km/h Sport Sedans & Coupes V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars W 168mph 270 km/h Y 186mph 300 km/h Z 149mph+ 240 km/h+(let suppose so)

On the Yangon-Nay Pyi Taw Expressway, car tires are often open, and even more important is the speed limit.

The tire has a max speed rating of 160kmh, but the best way is to test it with a new tire.

Therefore, you should not drive at max speed. Tires also have an expiration date and a manufacture date. The manufacture date is always required.

The manufacture date is usually framed in four boxes. The first two digits are the tire production week and the last two digits are the year.

This link shows the 1105 after YYY in the frame. It can be read that it was released in the 11th week of 2005.

(PS: The picture and text are copied from the link, so just look at the outside wheel.)

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...

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...
