DOHC
To determine if your 50cc moped is a 2-stroke or a 4-stroke, check the engine design and oiling system. A 2-stroke engine typically has fewer components, no separate oil reservoir, and requires mixing oil with fuel. In contrast, a 4-stroke engine has a separate oil system and usually features a valve train with camshafts and timing mechanisms. Additionally, you can consult the owner's manual or look for identifying marks on the engine.
The engine on a train is behind the driver.
The engine of an old train would be a steam engine.
The "Engine".
The engine or locomotive.
In swedish 'lok' means 'train engine"
In most cases the car at the front of a train is the engine or the locomotive. However, sometimes the train is pushed from behind and then the engine is the car at the end.
The weight of a train engine varies depending on the type of engine. A diesel engine can weigh as much as 250 tons while a steam engine would be about 100 tons.
