182. エンジン
エンジンは、自動車を推進するために必要な動力を生み出す機械です。一般的な車両では内燃機関がガソリンやディーゼルを燃焼し、電気自動車では内燃機関の代わりに1基以上の電動モーターを使用します。
多くの部品が連携してエネルギーを機械的動力へ変換します。確実な作動と車両安全のため、適切な潤滑、冷却、整備、排出ガス制御が重要です。
What does a vehicle engine do?
An engine converts energy into mechanical power that can be used to drive the vehicle's wheels. Internal-combustion engines obtain this energy by burning fuel, while electric vehicles use electrical energy in traction motors.
What are common signs of an engine problem?
Possible signs include unusual noises, loss of power, excessive smoke, overheating, fluid leaks, difficult starting or an engine warning light. These symptoms can have many different causes and should be investigated when necessary.
Why is regular engine maintenance important?
Maintenance helps keep lubrication, cooling, fuel, ignition and emissions systems working correctly. Following the manufacturer's service requirements can improve reliability and help prevent serious mechanical damage.
