Engine power reduction can be caused by fuel system malfunctions, intake system issues, or ignition system failures. Below are detailed explanations: Fuel System Malfunctions: Faulty fuel pumps, clogged fuel filters, or carbon buildup in fuel injectors can all lead to decreased engine power. Intake System Issues: Blocked air filters, leaks in the intake ducts, or carbon deposits on the throttle body can result in insufficient air intake. This causes weak acceleration, slow speed increase, and a jerky feeling. Ignition System Failures: Poor spark plug performance can prevent the proper combustion of the air-fuel mixture in the combustion chamber, and in severe cases, lead to engine misfires.

How to solve the oil burning issue in Peugeot 3008 1.6T?

It is usually caused by the aging of the valve oil seal rubber, and replacing this part can solve the problem. Here is the relevant introduction: 1. Oil burning: Oil burning generally manifests as blue exhaust smoke coming out of the tailpipe while driving, which indicates that excessive engine oil has entered the combustion chamber and participated in combustion. Under normal circumstances, the engine will also burn a small amount of oil from the cylinder block, pistons, and lubrication during operation. However, what we are discussing here is oil burning that exceeds the normal range. 2. Engine oil: Engine oil, also known as engine lubricant, plays roles such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion prevention, and shock absorption. It is known as the 'blood' of a car.

What is the equivalent Chinese emission standard for Euro IV with OBD?

Euro IV with OBD is equivalent to China IV standard. China IV standard refers to the fourth phase of national motor vehicle pollutant emission standards in China. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as the active layer of catalytic converters, secondary air injection, and exhaust gas recirculation systems with cooling devices, these standards control and reduce vehicle emissions to below specified limits. Methods to check a vehicle's emission standard: 1. Check the motor vehicle certificate of conformity; 2. Look for the vehicle delivery checklist; 3. Log in to the motor vehicle exhaust pollution supervision and management website; 4. Check the back of the environmental protection label on the vehicle's front windshield; 5.
