Three-way catalytic cleaner is effective. Here is extended information about three-way catalytic cleaners: 1. Functions of three-way catalytic cleaner: Improves the oxidation-reduction efficiency of the three-way catalytic converter, reduces exhaust emissions, unclogs the three-way catalytic converter pipes, lowers exhaust back pressure, and enhances engine horsepower. It also reduces fuel consumption and extends the service life of the three-way catalytic converter. 2. When a car operates at low temperatures for a long time, the three-way catalytic converter cannot activate: Carbon soot emitted by the engine will adhere to the surface of the catalyst, preventing contact with CO and HC. Over time, this can clog the pores of the carrier, affecting its conversion efficiency. Additionally, if exhaust emissions are obstructed, the engine's power cannot be fully utilized, which is why many vehicles struggle to reach high speeds.

Is the three-way catalytic converter cleaner useful? From a technical perspective, it is a product designed to clean carbon deposits in the catalytic converter. The catalytic converter is the heart of the exhaust system, processing harmful gases like carbon monoxide, but long-term use can lead to carbon buildup and clogging. The cleaner is added to the fuel, dissolving carbon deposits during combustion and helping restore the converter's efficiency, such as improving fuel consumption and exhaust emissions. However, it is not a cure-all: it only works for mild clogging issues. If the catalytic converter is severely damaged or physically deformed, the cleaner may be ineffective or provide only temporary relief. I have seen many cases where high-quality products can temporarily solve the problem, but inferior ones may corrode components. Based on automotive engineers' opinions, it is recommended to use it every 10,000 to 20,000 kilometers as preventive maintenance, but it cannot replace professional diagnostics.

How many cylinders does a W12 have?

W12 refers to 12 cylinders, where 'W' denotes the W configuration, meaning there are four banks of cylinders arranged at an angle, with 3 cylinders in each bank. W12 engines are quite rare, but some vehicles are equipped with this type of engine, such as the Audi A8, Volkswagen Phaeton, and Bentley Continental. The displacement of a W12 engine typically exceeds 6.0 liters, and most large-displacement engines of this type are naturally aspirated. Engine displacement is the total volume of all the cylinders in an engine, usually measured in liters. The cylinder volume refers to the gas volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder bore and piston stroke.
