EGR (Exhaust Gas Recirculation) reduces NOx emissions by recirculating a portion of exhaust gas back into the engine.

• EGR valve controls the flow of exhaust gas back into the engine

• Recirculated exhaust gas reduces combustion temperature and lowers NOx emissions

• EGR system can get clogged with carbon buildup over time

• EGR malfunction can cause engine performance issues and increased emissions

Engine oil functions include lubrication, cooling, cleaning, sealing, and corrosion prevention.

• Lubrication: reduces friction between moving parts

• Cooling: helps dissipate heat from the engine

• Cleaning: removes dirt and debris from the engine

• Sealing: prevents leaks and maintains compression

• Corrosion prevention: protects engine components from rust and corrosion
