Why is the power different after changing the transmission?

The reasons for the difference in power after changing the transmission are as follows: Incorrect use of transmission fluid: Before replacing the automatic transmission fluid, the vehicle should be parked on a level surface with the handbrake engaged and the gear selector in the P position. Prior to draining the ATF, the transmission should be warmed up to operating temperature (or the fluid should be changed after driving) to reduce the viscosity of the fluid and ensure that impurities and sediment are drained along with the fluid. Open the drain plug to release the fluid, and carefully inspect the condition of the ATF to analyze the state of the automatic transmission. Issues with the transmission valve body: If the transmission valve body is damaged, it may cause sticking. If there is a leak, it can lead to gear shift shock during the shifting process, significantly reducing shift efficiency and also causing a decrease in the vehicle's power. Mismatch between the transmission computer and other computers: Changing the transmission requires program matching because the computer needs to better control the transmission by adjusting the current values of various solenoids to ensure the transmission outputs power more effectively.

What Causes Unstable Idle Speed and Obvious Body Shaking When Starting the Car?

Reasons for unstable idle speed and obvious body shaking when starting the car are as follows: Low ignition energy causing shaking: The first issue a car faces during cold start is low temperature. The engine's internal temperature is insufficient, and both fuel and lubricating oil temperatures are inadequate. Therefore, during cold starts, more fuel should be injected to meet power requirements. The larger the spark plug gap, the smaller the ignition energy. At low temperatures, fuel atomization is poor, requiring higher ignition energy. Over time, the spark plug's ignition gap tends to increase, leading to reduced ignition energy, which affects power performance and causes the car to shake. Inappropriate air-fuel mixture causing shaking: If the air-fuel mixture ratio in the car's engine compartment is not accurately adjusted, the car is prone to shaking. In closed-loop control cars, the oxygen sensor's minimum operating temperature is 370 degrees Celsius. If the car has just been started, the exhaust pipe temperature does not reach 370 degrees Celsius, so the oxygen sensor does not work. At this time, the ECU makes incorrect judgments, leading to errors in controlling the air-fuel mixture and ignition timing through its actuators, thereby reducing the car's power output and causing shaking.

What Happens When the Engine Cylinder Valve Fails?

When the engine cylinder valve fails, the car will produce abnormal noises, experience unstable idling, poor acceleration, lack of power, and overall weakness. In severe cases, the engine may fail to start. This significantly impacts the vehicle, causing poor sealing, air leaks, excessive carbon buildup, and oil burning. Introduction to Valves: Engine valves, also known as cylinder valves, include intake valves and exhaust valves for each cylinder to facilitate air intake and exhaust. Typically, an engine has one intake valve and one exhaust valve. The size of the valves determines the amount of air intake and the efficiency of exhaust gas expulsion. The goal is to maximize the intake of fresh air and the expulsion of exhaust gases, so in design, intake and exhaust valves are made as large as possible to achieve these objectives. Valve Working Principle: During engine operation, valves move at high speeds. Larger valves have greater inertia, requiring higher strength for both the valves themselves and their driving mechanisms. Therefore, a single valve cannot be made excessively large. To overcome this limitation, engineers devised increasing the number of intake and exhaust valves to enhance air intake and exhaust efficiency. This led to the development of the commonly heard four-valve engine, where each cylinder has two intake valves and two exhaust valves, typically found in high-end engines.

Where is Ora Electric Vehicle Produced?

Ora is an electric vehicle brand under Great Wall Motors, established in 2018. Here is a detailed introduction to Ora electric vehicles: 1. Development: Among Chinese automotive companies, Great Wall was the first to establish an independent new energy brand for its new energy vehicle business. With the launch of the Ora ORA brand, China's first dedicated electric vehicle platform—the ME platform—was introduced. From the chassis to the interior and exterior, it incorporates advanced smart connectivity technologies, achieving substantial breakthroughs in space, safety, and efficiency. The Ora brand is the result of Great Wall Motors' decade-long dedicated research and development, avoiding "oil-to-electric" conversions or "policy-driven vehicles." Leveraging decades of technical expertise, Great Wall launched its first native pure electric model, the Ora i-Q, providing consumers with more green mobility options while ensuring high-quality standards. 2. Design Philosophy: Ora integrates open design elements, aiming to offer the new generation of consumers a series of safe, reliable, and fun-to-drive pure electric vehicles with a positive and friendly approach. 3. Brand Positioning: Ora positions itself as a car brand that "loves women more," committed to establishing the correct values for the industry in treating female users.
