The solutions to reduce engine noise in BYD Qin are: 1. Install sound insulation equipment for the engine; 2. Switch the driving mode to economy mode. Taking the 2020 BYD Qin as an example, it belongs to the compact car category with body dimensions of: length 4675mm, width 1770mm, height 1500mm, wheelbase 2670mm, luggage compartment volume of 450L, and curb weight of 1630kg. The 2020 BYD Qin features a front MacPherson strut independent suspension and a rear torsion beam non-independent suspension. It is equipped with a permanent magnet electric motor delivering a maximum power of 100kW and maximum torque of 180Nm, paired with a 1-speed fixed gear ratio transmission.

I've been driving a BYD Qin for several years and have encountered the issue of loud engine noise, but there are actually some tricks to solving it. If the noise sounds like a roar, first check if the engine oil needs to be changed; I've tried switching to synthetic oil, and lower viscosity works better, reducing friction noise. The soundproofing pad under the hood might also be aging—just spend a little money to add some soundproofing foam. Tightening the engine screws is also crucial, as loose ones can easily cause vibrations and noise. If the noise is noticeable during acceleration, cleaning the intake tract and air filter will do the trick—this is something you can do yourself. Remember not to idle for too long and use ECO mode more often. When the hybrid system is well-tuned, the engine starts more smoothly, and the noise naturally decreases. After following these steps, the noise is under control, and driving becomes much more pleasant.

As someone who frequently tinkers with cars, addressing the engine noise in a BYD Qin requires a step-by-step approach. The noise source could stem from multiple areas: poor sealing of the sound insulation system, aged engine oil increasing friction, or loose fasteners. I recommend first using a multimeter to check oil pressure and temperature to confirm if it's an oil quality issue. Switch to a new synthetic oil with a viscosity of 5W-30 to reduce friction noise. If the soundproofing material is worn, replacing the gasket under the hood can help. Check if the air intake filter is clogged—cleaning or replacing it should resolve the issue. The unique startup noise of hybrids can be improved through software updates or adjusting the driving mode. It's best to schedule regular inspections at a service center to prevent minor issues from escalating. These professional methods are reliable for ensuring a quiet and safe drive.

I care about eco-driving, and the high noise level of the BYD Qin often indicates lower energy efficiency. The solution is proper maintenance: use low-resistance synthetic oil to reduce friction noise, and replace the air filter regularly to ensure smooth air intake. A well-maintained engine not only reduces noise but also saves fuel and cuts carbon emissions. Try optimizing the hybrid mode in the vehicle settings and accelerate smoothly to avoid high RPMs. These simple steps can reduce noise and benefit the environment. I've practiced them myself, and the results are noticeable.

Encountered BYD Qin noise issues, I solved them with cheap methods. First, checked the engine oil and changed it myself when dirty, opting for budget synthetic oil, costing around 20-30 yuan. Added a layer of soundproofing material under the hood, bought online for tens of yuan; tightened engine screws to prevent vibration noises. Cleaned the air filter myself without spending extra. Avoid aggressive acceleration during driving to reduce noise. These DIY fixes are simple and cost-effective, but for major issues, it's safer to consult professionals.
