Causes of severe idle vibration in Civic: Air Flow Sensor Issues: It may be due to chaotic signals from sensors like the air flow sensor or fuel consumption sensor in the engine, causing the ECU to receive inaccurate data and resulting in engine vibration at idle. Engine Oil Problems: The vibration could occur because the engine oil fails to circulate promptly during operation, depriving the engine of optimal mechanical operating conditions. ECU Malfunction: Another common factor is inherent issues with the vehicle's ECU itself. Poor signal reception from the engine or chaotic output signals from the ECU can lead to engine operational problems.

Can I Take Back the Old Car Battery When Replacing It?

Can I Take Back the Old Car Battery When Replacing It? The following is relevant information: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the battery referred to is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Notes: You can take back the old car battery when replacing it, but it is generally sold directly to the battery store for recycling. After replacing the battery, the original battery is of no use to the vehicle owner and is difficult to store. If it leaks, it can have a certain impact on surrounding items.

What is the difference between the high-power and low-power versions of the H6?

High-power version is more expensive and better equipped than the low-power version. The related explanations are as follows: 1. Introduction The engine technology is advanced. The high-power version adopts a direct-injection engine, which allows for more complete combustion of gasoline, enhancing fuel efficiency. The high-power version has 19 more horsepower and provides 75 more torque than the low-power version. The maximum torque RPM is also reduced to 1400, making it relatively more fuel-consuming. 2. Additional Notes: In terms of exterior appearance, the high-power version is more attractive than the low-power version. There are also significant improvements in functional configurations and safety features. The compression ratio of the high-power version is 10:1, while that of the low-power version is 11:1.

Is it illegal to modify a car's steering wheel?

Modifying a car's steering wheel is not illegal. Here is the relevant information: 1. Introduction: A steering wheel is a wheel-shaped device used to control the direction of a car. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. 2. Function: The steering wheel is generally connected to the steering shaft via splines. Using a steering wheel with a larger diameter reduces the force required from the driver when turning. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel more reasonable in the vehicle.

What are the three elements in an automotive three-way catalyst?

Three-way refers to the three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name three-way. Relevant explanations are as follows: 1. Introduction: The three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. The three-way catalyst converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Supplementary explanation: The three-way catalytic converter also contains certain purifying agents. When toxic gases pass through the exhaust pipe, the three-way catalytic converter releases these purifying agents onto the carrier, forming a catalytic effect to purify the toxic gases.

Is It Necessary to Use Iridium Spark Plugs in Regular Cars?

Regular cars can switch to iridium spark plugs, which can increase power and also reduce fuel consumption. What are spark plugs made of: Spark plugs mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. What types of spark plugs are there: Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Replacement cycle for spark plugs: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
