Mostly refers to the engine of cars, motorcycles, etc. The engine head of a motorcycle refers to the engine. Introduction to motorcycle engines: A motorcycle engine is a machine that ignites the fuel mixture entering the cylinder, converts the thermal energy generated by combustion into mechanical energy, and transmits the power through the crankshaft to the rear wheel of the motorcycle via the transmission mechanism, thereby providing the driving force for the vehicle. Basic knowledge: Literally, "engine" can be understood as a machine that generates power. Depending on the method of energy conversion, it can be classified into electric engines, hydraulic engines, wind engines, nuclear engines, thermal engines, etc.
I've been riding motorcycles for many years and often hear people talk about big engines and small engines. The meaning is quite simple. In the motorcycle community, 'engine' refers to the motor. A big engine usually means one with a large displacement, like those above 250cc. They offer strong power, fast acceleration, and are suitable for high-speed riding or long-distance trips—some off-road bikes are equipped with these. The downside is higher fuel consumption, and they might feel a bit heavy for daily use. Small engines, on the other hand, have smaller displacements, around 125cc, and are lightweight, fuel-efficient, and very agile for city commuting. When I was younger, I used a small-engine scooter—easy to park and effortless to ride. Choosing between them depends on your needs: big engines are stable for long trips, while small engines are sufficient for city riding. Remember, regular oil changes are crucial—don’t let carbon build up in your engine.
