What Causes the Abnormal Noise When Starting the Ora Black Cat?
2 Answers
Ora Black Cat starting abnormal noise may be caused by a fault in a certain component of the car engine. The following is a detailed introduction about car engines: 1. Overview: The car engine is the device that provides power to the car, determining its power, economy, stability, and environmental friendliness. Depending on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power, among others. 2. Others: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which can convert the chemical energy of fuel into the mechanical energy of piston movement and output power externally. Gasoline engines have high rotational speed, small mass, low noise, easy starting, and low manufacturing costs. Diesel engines have a large compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engines.
When I start my Ora Black Cat, there's a creaking sound. I suspect it's an issue with the chassis suspension. Last year, I drove tens of thousands of kilometers in the city, with quite a few bumpy roads, which wore out the bushings of the rear suspension. The body shakes a lot when starting, and once the rubber buffer pads loosen, the noise starts. Additionally, the brake discs sometimes rust or accumulate dirt, and the torque output during startup causes slight friction with the brake pads, which is also annoyingly noisy. I tried tightening a few screws myself, but the problem wasn't resolved. Later, I took it to a professional shop for inspection, and it turned out the battery bracket's fasteners were loose. After the mechanic tightened them, the noise disappeared. I recommend regularly checking the chassis, especially since rubber parts age quickly. Don't wait for a major issue to arise—safety comes first when driving.
