Mainly, yes, but there are minor differences, and of cource the bus engine is usually largest :)
Car engines way back work the same as they do now with very minor changes.
the engine powers a car,bus or a truck
Same as a regular car engine but to give it the extra power it has some more cylinders
Any of your examples will work the same.
can a 302omc engine work for a car
The car would need to have more velocity than the school bus.
they both have wheels and engines and seatbelts
No.
A car engine has many moving parts hundreds of them and they all have to work or the engine won't work, but it is very simple to explain how it works. When you ride a bike you are the engine.your legs go up and down and round and round. The pistons do the same thing, as you push down on the pedals the bike moves. The pistons do the same thing, they push on a part called a crankshaft and the force is transferred to the transmission and then the wheels and the car moves. An engine that uses gas was once called an internal combustion engine. In simple terms it has fire and pressure inside the cylinders where the pistons are. A car engine is like a steam engine they work the same way. But the pressure is made inside the cylinder and not in a boiler as a steam engine does .It's the pressure that makes it go.
probably, the car is safer because you know who the driver is, and it is lighter. the bus, you cant really trust the driver, and it is heavier, plus there is no engine in the front to protect you. thanx.
A car engine is a heat engine, but there are various types of heat engines outside the realm of car and truck engines.
Because without it the computer would not work. It is pretty much the same as having an engine in a car.
