Can a car engine be replaced with another engine?

[LilaRose]

It is possible to replace a car engine. Here are the relevant details: Registration: A car engine can be replaced as long as the new engine has a certification of compliance. You can then register the change with the vehicle management office. Once the registration is completed, the car can still undergo annual inspections and be driven legally. Four-stroke cycle: During the intake stroke, the piston moves downward to draw in the combustible air-fuel mixture. During the compression stroke, the piston moves upward to compress the mixture. In the power stroke, the ignited mixture pushes the piston downward. During the exhaust stroke, the piston moves upward to expel the exhaust gases produced by combustion. Required documents: "Motor Vehicle Modification/Registration Application Form," signed by the authorized person for company vehicles or by the owner for personal vehicles.
