What is a Torque Vectoring System?

A torque vectoring system refers to a system that can distribute power between the left and right wheels of a vehicle. When navigating a curve, it allocates more power to the outer wheel, enhancing stability during cornering. Here are the details: 1. When the vehicle turns right: The left rear wheel transmits more power to the road, so the torque vectoring system allocates more driving force to the left rear wheel. 2. When the vehicle turns left: The torque vectoring system delivers more driving force to the right rear wheel, causing it to transmit more power to the road in this scenario. 3.

Will Carbon Deposit Cleaning Block the Catalytic Converter?

Cleaning carbon deposits will not block the catalytic converter. This is because fuel additives clean carbon deposits gradually, and the particles removed are very small, so they will not cause the catalytic converter to become blocked. Below is an introduction to the automotive catalytic converter: 1. Appearance: The catalytic converter looks like a metal can from the outside, but inside it contains a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. 2. Exhaust Gas Purification Function: The precious metals act as catalysts, reducing HC and CO in the exhaust gases into water and CO2, while decomposing NOx into nitrogen and oxygen. This is the exhaust gas purification function of the catalytic converter.
