What is a Car Three-Way Catalytic Converter?

Three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. Here are the details: Function: The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted by automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Design Principle: When high-temperature exhaust gas passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx, promoting certain oxidation-reduction chemical reactions. Among them, CO is oxidized at high temperature to become colorless and non-toxic carbon dioxide gas; NOx is converted into nitrogen and oxygen. The three harmful substances are converted into non-toxic gases, thereby purifying the exhaust emissions.

What are the symptoms of a broken transmission gear?

The symptoms of a broken transmission gear include difficulty in shifting gears, unusual odors inside the transmission case, the car not moving when engaged in gear, abnormal noises from the transmission, and excessive noise. Transmission gears often operate under varying speeds and loads, and the gear surfaces are subjected to impact loads, leading to gear damage. Common types of transmission gear damage include: 1. Wear on the end face of constantly meshing gears. The helical gear end face should have a certain axial clearance to ensure smooth operation. If the gear end is worn and grooved, it can be repaired by grinding; 2. Wear on the journal of constantly meshing gears, needle bearings, and seat holes. The clearance between the meshing gear seat hole, needle bearings, and journal should be between 0.01mm and 0.08mm. Otherwise, replacement is necessary.

What are the reasons for a motorcycle not stalling when parked?

The main reason for a motorcycle not stalling when parked is due to the influence of adverse weather conditions. Reasons influenced by adverse weather conditions: Engine dampness, wet circuits, blocked air filters, and oxygen-deficient mixture ratios can cause this situation. The idle speed and mixture ratio may temporarily become severely imbalanced or abnormal. If you must continue riding the motorcycle under these conditions, you can first gently dry the damp parts. Ordinary motorcycles are quite sensitive to weather influences, so it's best not to hastily make adjustments or repairs out of urgency. Solutions for a motorcycle not stalling when parked: Check if the crankshaft oil seal is damaged. You can remove the external parts of the crankshaft oil seal and inspect the seal. If the oil seal is damaged, it should be replaced with a new one.

What Causes the Metal Friction Sound in the Engine Compartment?

Introduction to the causes of metal friction sound in the engine compartment: Hydraulic lifters: If the oil pressure is too low or the hydraulic lifters themselves are worn, air entering the lifters can cause a metal friction sound when starting the car. Worn valve rocker arms: Excessive wear on the valve rocker arms leading to excessive clearance or too much sludge and carbon buildup, or a dirty throttle body can also cause a metal sound during cold starts. Improperly installed engine front cover: During cold starts, the output power increases, and the engine noise correspondingly increases, which is normal. However, if the noise is too loud, you can mention this situation during maintenance.
