Is a 1.5t engine a 3-cylinder or 4-cylinder?

[BeauFitz]

1.5t engines come in both 3-cylinder and 4-cylinder configurations. Below is how an engine works: 1. Intake stroke: The piston is driven by the crankshaft to move from top dead center to bottom dead center, while the intake valve opens and the exhaust valve closes; 2. Compression stroke: The piston moves from bottom dead center to top dead center, with both intake and exhaust valves closed; 3. Combustion expansion stroke: Both intake and exhaust valves remain closed, the spark plug ignites, and the air-fuel mixture burns intensely; Additional information: An engine is a machine that converts other forms of energy into mechanical energy. Based on working principles, engines are categorized into: external combustion engines, internal combustion engines, gas turbines, and jet engines.
