How Engine Pistons and Connecting Rods Work: Converting Combustion to Motion
Pistons are the fundamental workhorses of every internal combustion engine, converting the explosive force of combustion into the mechanical energy that powers your vehicle. These cylindrical components work in perfect harmony with connecting rods to transform linear motion into the rotational force that drives your wheels. Whether you’re troubleshooting engine performance issues or planning a […]
How Combustion Cycles Work: Otto vs Diesel Cycles Explained
Combustion cycles are the fundamental thermodynamic processes that convert chemical energy in fuel into mechanical energy in your engine. The two primary cycles – Otto (gasoline) and Diesel – operate through distinctly different compression, ignition, and expansion phases that determine engine characteristics, efficiency, and performance. Understanding these cycles reveals why gasoline engines require spark plugs […]
How Cylinder Heads Work: The Engine’s Upper Architecture
The cylinder head is the critical upper component of your engine that houses the combustion chamber, valves, and valve train components. This precisely engineered casting forms the top of each engine cylinder and plays a vital role in controlling airflow, fuel delivery, and exhaust gas removal. Modern cylinder heads integrate complex port designs, cooling passages, […]
