Determining the Engine Type in Your Car

Posted on

Identifying the engine type in your car is crucial for various reasons, including maintenance, repairs, and performance upgrades. Knowing the specific engine model allows you to access detailed technical information, locate compatible parts, and make informed decisions about modifications. This comprehensive guide will provide you with a step-by-step approach to identifying the engine in your car.

1. Check the Vehicle Identification Number (VIN)

The VIN, a unique 17-character code, contains valuable information about your car, including the engine type. It can be found on the driver’s side dashboard, the door jamb, or the vehicle’s title.

  • Decode the Eighth Character: The eighth character in the VIN represents the vehicle’s engine code. It usually indicates the type of engine, such as V8, I4, or Diesel.

2. Consult the Vehicle’s Service Manual

The service manual, which is typically available online or from your dealership, contains detailed specifications about your car, including the engine type. It provides a comprehensive overview of the engine’s components, dimensions, and performance characteristics.

3. Look under the Hood

Open the hood and examine the engine compartment. You may find a badge or label indicating the engine type. It could be located on the engine cover, the air intake manifold, or the side of the engine block.

4. Check the Engine Code on the Engine Block

Every engine has a unique engine code cast or engraved on the engine block. It is usually located on the side or top of the engine. The code consists of numbers and letters that identify the engine model. You can use this code to cross-reference with online databases or service manuals to determine the exact engine type.

5. Contact Your Dealership or Manufacturer

If you are unable to locate the engine type using the above methods, you can contact your dealership or the car manufacturer. They will be able to provide you with the specific engine information based on your vehicle’s make, model, and year.

6. Use an OBD-II Scanner

If your car is equipped with an On-Board Diagnostics (OBD-II) port, you can use an OBD-II scanner to retrieve information about the engine. Connect the scanner to the OBD-II port, which is usually located under the dashboard, and access the engine data.

Understanding Engine Types

Once you have identified the engine type in your car, you can delve into its specific characteristics. Here are some common engine types:

  • Inline (I) Engine: Cylinders are arranged in a straight line, with one cylinder head at each end.
  • V-Engine: Cylinders are arranged in two banks, forming a V-shape.
  • Flat (H) Engine: Cylinders are arranged horizontally, with two banks opposing each other.
  • Rotary Engine: A triangular rotor spins within a figure-eight-shaped housing, creating combustion chambers.
  • Diesel Engine: Uses compression ignition instead of spark plugs to ignite the fuel.

Additional Considerations

In addition to the engine type, there are other factors that influence the performance and characteristics of an engine, such as:

  • Displacement (Volume): Measured in liters or cubic inches, it represents the total volume swept by the pistons during one combustion cycle.
  • Number of Valves: The number of intake and exhaust valves per cylinder affects the engine’s efficiency and airflow.
  • Fuel System: The type of fuel system (e.g., fuel injection, carburetor) determines how fuel is delivered to the engine.
  • Aspiration: The way in which air is introduced into the engine (e.g., naturally aspirated, turbocharged, supercharged).


Identifying the engine type in your car is essential for proper maintenance, repairs, and performance modifications. By using the methods described in this guide, you can easily determine the specific engine model and access detailed information to keep your car running smoothly and efficiently. Remember to consult the vehicle’s service manual or contact your dealership if you encounter any difficulties in identifying the engine type.
