      We need a book on how the modern automobile engine works. It is easy to understand how the engine of the 50’s work They are totally mechanical. But today’s engines substitute electronic fuel injection for a mechanical carburetor, installed catalog convertor and O2 sensors that affect engine performance Implement a host of sensors that never before existed. Eric Cook could write a tutorial on how a modern engine works and it would sell because of his following.

        A car’s internal combustion engine is a complex system that converts fuel into mechanical energy to propel the vehicle. The most common type of internal combustion engine in cars is the four-stroke piston engine. Here’s a simplified explanation of how it works:

        Intake Stroke:

        The process begins with the intake stroke. The engine’s intake valve opens, and the piston moves down the cylinder. As it does so, a mixture of air and fuel is drawn into the combustion chamber from the carburetor or fuel injection system.
        Compression Stroke:

        The intake valve closes, and the piston moves back up the cylinder. This compresses the air-fuel mixture, making it more combustible. The compression stroke is crucial for the efficiency of the combustion process.
        Power Stroke:

        Once the air-fuel mixture is compressed, a spark plug ignites it. The ignited mixture rapidly expands, producing a high-pressure force that pushes the piston down the cylinder. This is the power stroke, and it’s the phase where the engine generates mechanical energy.
        Exhaust Stroke:

        After the power stroke, the exhaust valve opens, and the piston moves back up the cylinder. This expels the burned gases from the combustion chamber through the exhaust system.
        These four strokes (intake, compression, power, and exhaust) together make up one complete cycle. Most car engines are designed with multiple cylinders, and each cylinder undergoes these four strokes in a specific sequence, with the power strokes occurring at different times for each cylinder.

        Additionally, modern cars often use a variety of technologies to improve efficiency and reduce emissions. These include fuel injection systems, electronic ignition systems, and variable valve timing mechanisms. These technologies help optimize the combustion process and enhance overall engine performance.

        It’s important to note that there are different types of internal combustion engines, such as diesel engines and rotary engines, each with its own set of characteristics. However, the four-stroke piston engine is the most common in passenger vehicles.IF you want to name your engine i have a best suggestion for you must click here
