Has the 2020 ZF 9AT been resolved?

2020 ZF 9AT has not been resolved. Here is more related information: ZF 9AT issues: The main problem with the ZF 9AT is its unreasonable gear ratio distribution. The first gear ratio is 4.7, while the ninth gear ratio is 0.48, resulting in a span of 9.8 (4.7÷0.48=9.8). In comparison, the span of the GM 9AT is 7.6. Additionally, the gear ratio change between the first and second gears of the ZF transmission is more significant, leading to more noticeable jerks. Compared to Mercedes and GM, whose ninth gear ratios are around 0.6, ZF's ninth gear ratio is as low as 0.48, which is somewhat aggressive. GM 9AT: The gear ratio of GM's 9AT is more reasonable. Its overdrive gears are only the 8th and 9th gears, balancing fuel efficiency with practicality—the 9th gear can engage at a speed of 95 km/h. According to different cycle condition statistics, the usage frequency of the 9th gear is between 13% and 52%, while ZF's is only about 10%.

What are the symptoms of a damaged exhaust manifold gasket?

Exhaust manifold gasket damage most directly manifests as air leakage, loud noise, and weak engine performance. Below is additional information on exhaust manifold gasket damage: 1. Improper operation: When a vehicle reaches the top of a slope, the engine temperature is relatively high, and the exhaust gas temperature is also very high, resulting in high temperatures being transmitted to the exhaust pipe and other components. Many drivers use the exhaust brake as soon as they start descending the slope, but due to the high temperature, the exhaust manifold gasket is prone to burning out. 2. Using the exhaust brake at high RPM: Engaging the exhaust brake when the engine is running at high RPM can create excessive instantaneous pressure, which is one of the reasons for exhaust manifold gasket failure. According to engineers from Shaanxi Automobile Research Institute, it is recommended that users use the exhaust brake below 1500 RPM.

How Many Liters of Fuel Does a Car Consume When Running the Air Conditioner for One Hour?

It consumes approximately 2-3 liters of fuel per hour. Since the engine remains idling, the fuel consumption is not very high. Here is some relevant information: Reason for fuel consumption: The power source of the car's air conditioning system comes from the engine. The engine drives the air conditioning system compressor via a belt, and the power for the air conditioning system fans also comes from the car. Therefore, running the air conditioner will definitely increase fuel consumption. A noticeable reaction is that when the air conditioner is turned on at idle, you can clearly feel the engine speed decrease because the compressor adds an extra load. Inspection: However, if fuel consumption is unusually high, it is recommended to check the fuel system. If there is no noticeable lack of power when accelerating, the issue is likely due to fuel leakage in either the high-pressure or low-pressure system. Alternatively, it could be a problem with the fuel from the gas station or the fuel gauge.

How Many Turns Can an F1 Racing Steering Wheel Make?

An F1 racing steering wheel can only make half a turn. Here are some additional details: 1. Reasons why an F1 racing steering wheel can only make half a turn: Due to the small size of the F1 racing cockpit, drivers can only keep the steering wheel straight without performing any additional movements. F1 cars are extremely fast, and turning the steering wheel a full circle and then turning it back would take too much time. Since F1 cars are four-wheel drive, a half-turn of the steering wheel is sufficient to make a U-turn. Additionally, the F1 steering wheel includes all the switches the driver uses to control the car. 2. Standard steering wheel handling techniques are as follows: The positions of the left and right hands on the steering wheel are described using fixed clock face positions. The starting position for the left hand: 9~10 o'clock, and the starting position for the right hand: 3~4 o'clock.

What Causes the Temperature Warning Light to Illuminate When the Coolant Temperature is Normal?

The temperature gauge shows normal readings but the red warning light is on, which is generally a false alarm from the coolant temperature warning system. When the owner adds antifreeze, if the vent hole on the side of the reservoir's damping tube is positioned too low, it can create a compressed air column inside the damping tube. This causes the liquid level in the damping tube to be significantly lower than that in the expansion tank and close to the sensor's alarm threshold. Vibration during driving can easily trigger a false alarm. Below is an introduction to the temperature gauge: 1. Normal coolant temperature: The coolant temperature typically displays between 70-90°C after the engine warms up, which is considered normal. If the coolant level in the radiator is low, the temperature will rise, requiring the addition of water. If the temperature gauge needle approaches the 'H' mark or the red danger zone, and the temperature warning light comes on, it indicates that the engine coolant temperature is excessively high. 2. Working principle: The temperature gauge sensor is a thermistor-type sensor threaded into the engine's coolant passage. The thermistor determines the current flowing through the temperature gauge coil, which drives the needle on the gauge to move accordingly.

Is the Corolla 1.2T engine durable?

Corolla 1.2T engine is durable. Below are relevant introductions about automotive engines: Function of automotive engines: It is the device that provides power for the car, serving as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. Depending on the power source, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement and output power externally. Engine maintenance methods: Use high-quality engine oil, use qualified coolant, regularly clean radiator scale, regularly remove carbon deposits from the car, replace the car's three filters on time, and maintain reasonable engine speed.
