Engine Problems In Modern Cars Common

Engine is a device that converts energy into mechanical work. There are many different types of motors, each operating on a separate principle and used in different fields.

As cars become a popular means of transportation, it is important to understand common engine-related problems. The engine is considered the “heart” of the car, and timely maintenance and repair will help the car operate more efficiently. Below is a summary of 6 common engine problems, their causes, and solutions.

Engine misfire phenomenon

When an engine won't start, it can cause a lot of trouble for the driver. Some of the main causes include:

• Weak or dead battery: This is the most common cause; the battery should be checked periodically.
• Dirty or faulty spark plugs: Spark plugs that do not spark will cause the engine to not start.
• Clogged fuel system: The fuel filter or fuel line may be clogged.
• Ignition coil or fuel pump failure: If the ignition coil fails, the engine will not receive the electricity it needs to start.

To fix this, users should clean the related parts and check the battery and fuel system.

According to research by Dr. James Anderson, Director of Research at the Michigan Automotive Technology Institute (2023) in 'Modern Automotive Engineering Challenges': 35% of engine no-starts are related to battery problems, 25% are due to spark plugs, and 20% are due to the fuel system.

Engine error not reaching high rpm

If the engine does not reach high rpm and is unstable, it could be due to:

• Carburetor system problems: Damaged or oily gaskets can reduce performance.
• Oily spark plugs: This can cause unstable ignition.

To solve this problem, you need to take your car to a service center to check and replace damaged components.

Engine error with stalling phenomenon

A stalled engine on the road is a dangerous situation. Possible causes include:

• Not enough fuel: Could be out of gas or a clogged fuel system.
• Camshaft gear failure: This reduces pressure in the combustion chamber.

Drivers should check fuel levels and fuel systems regularly to avoid this situation.

Engine power is not operating optimally

If your car feels like it's not as powerful as it used to be, the cause could be:

• Carburetor failure: Improper adjustment or inefficient economizer.
• Piston ring wear: This wear reduces the pressure in the combustion chamber.

Regular inspection and replacement of worn parts will help improve engine performance.

Car engine overheating

Engine overheating can cause serious damage. Causes include:

• Low coolant or contaminated coolant: Coolant level should be checked regularly.
• Water pump failure or radiator blockage: This prevents efficient circulation of coolant.

When this happens, stop the vehicle and have it checked immediately to avoid further damage to the engine.

The Society of Automotive Engineers (SAE International) in its report 'Engine Cooling System Analysis 2024' indicates that 42% of engine overheating cases are caused by lack of regular cooling system maintenance.

Engine knocking error

Knocking noises from the engine can come from:

• Using poor quality fuel: Low octane fuel can cause knocking.
• Valve clearance is too large or other parts are worn: This needs to be checked and adjusted promptly.

Early detection of knocking will help protect your engine from more serious damage in the future.

Understanding common problems in modern car engines not only helps drivers identify early signs of abnormalities but also helps save on repair and maintenance costs. Always maintain the habit of regular inspection and maintenance of the car to ensure safety when participating in traffic. If you encounter any problems, take the car to reputable repair centers for timely support.

FAQ – Frequently Asked Questions

1. What are the signs that your car engine needs maintenance?

Your car's engine needs maintenance if it shows signs such as: strange knocking noises, strong vibrations, smoke coming from the exhaust pipe, or a warning light on the dashboard. If your car is consuming more than 10% more fuel than average, it should also be checked.

2. What are the common engine repair costs?

Repair costs can range from $500.000 for a spark plug replacement to $15 million for a coil or fuel system replacement. Some major repairs, such as engine replacement, can cost up to $50 million.

3. How to check the coolant level in the engine?

Check the level engine coolant by opening the coolant reservoir cap when the engine is cold. The water level should be between the “MAX” and “MIN” marks. If lower, add appropriate coolant.

4. How long is the regular maintenance period for car engines?

Regular maintenance is usually every 5.000 km or 6 months, depending on driving conditions and vehicle type. This helps to detect potential problems early before they become major damage.

5. What measures can help prevent engine damage?

To prevent damage, drivers should take measures such as: periodically checking the oil system, ensuring adequate coolant levels, using high-quality fuel and replacing air filters regularly.
