The three-way catalytic converter is an emission control device in the engine, and its proper functioning determines the engine's fuel consumption, power, and emission performance. If it becomes clogged or malfunctions, the exhaust emissions will exceed the standard. It is recommended to perform a non-dismantling cleaning, either by using the "drip method" or by adding a cleaning agent to the fuel tank. The specific steps for the "drip method" are as follows: 1. Start the engine and turn it off after the water temperature normalizes; 2. Pour the cleaning solution into a specialized device and connect the device's output to the vacuum pipe; 3. Start the engine, maintain the RPM at around 2000, open the flow control valve, and slowly drip the solution into the intake manifold for approximately 30 minutes; 4. After cleaning, keep the engine running at the same RPM for 3-5 minutes to expel any residual liquid.

What Causes the Sizzling Sound When Starting a Car?

Reasons for the sizzling sound when starting a car: loose or aged belts, or possibly a malfunctioning starter. When starting the engine, the starter's gear engages with the ring gear on the engine's flywheel, causing the starter to rotate and drive the engine's flywheel. The engine flywheel is connected to the crankshaft, which is linked to the connecting rod, and the connecting rod is connected to the engine's piston. Many peripheral devices around the car engine require operation, such as the alternator, air conditioning compressor, water pump, power steering pump, etc. These devices are connected to the engine's crankshaft via belts and can operate once the engine starts. Belts are rubber products, which can age and wear out over time with prolonged use.

Which is faster in a straight-line acceleration: front-wheel drive or rear-wheel drive?

Rear-wheel drive is faster in straight-line acceleration because rear-wheel drive cars have better traction at the rear wheels during launch, allowing the car to accelerate more quickly. Rear-wheel drive vehicles typically use a longitudinally mounted engine, which takes up a significant amount of rear passenger space. The rear wheels of rear-wheel drive cars are heavier, resulting in greater inertia, which can lead to oversteer. Additionally, rear-wheel drive cars are more challenging to drive on icy or snowy roads. Most front-wheel drive cars use a front-mounted engine, positioned closer to the front. In front-wheel drive cars, the front wheels are responsible for both steering and driving, placing a heavier burden on them. During sharp turns, front-wheel drive cars may experience understeer. The traction of front-wheel drive cars is generally poorer, and if the rear wheels cannot provide sufficient grip, they may drag the front wheels, causing slipping.

The ECO in a car refers to the economic driving mode, which is further divided into active ECO driving mode and non-active ECO driving mode. When the ECO indicator light on the dashboard is on, it means the vehicle's economic mode is activated.

This is because, after activating this mode, the ECU control unit calculates the appropriate amount of fuel to provide to the engine, effectively reducing fuel consumption compared to normal driving mode.
