Why is it more efficient for car engines to have more cylinders?

That's not always the case.
For efficiency - to get the most useful energy out of every drop of fuel - there's an ideal size of the combustion chamber. Make it smaller, it tends to go a bit cold and combustion gets poorer, make it bigger it's harder to get all of the gases in and out.and combustion ALSO gets poorer.
So for efficiency, you want to use cylinders in an appropriate size, and as few as possible needed to give you the power you want.
If you need more power, you pretty soon run into the fact that a bigger cylinder isn't working as well, and it becomes more efficient to add more cylinders instead.
Keep in mind that adding cylinders isn't "free". The Engine gets bigger and heavier. Some of the Power goes into dragging the bigger Engine around. You need more parts. More parts cost more to make and create more friction.

Why do automotive engines have multiple cylinders?
A car having multiple cylinders makes the power evenly dispoursed so the engine runs more smoothly compared to 1 cylinder
What do cylinders mean for the amount of gas?
If you mean in a car, more cylinders=more pistons so uses more fuel. The larger the car the larger the engine must be to proper it so if fuel efficiency is what you want, you need the smallest car you can get away with that passes your drive test. many of these are so efficient now, they are underpowered-a common complaint.
What are two ways car manufactures air using to reduce air pollution?
More fuel efficient engines. Catalytic converters in the exhaust.
What were planes powered by before jet engines?
Propeller driven piston internal combustion engines. Similar to the one in your car, except planes usually used either radial or rotary engines, both of which have the cylinders arranged in a circle and typically have a multiple of 9 cylinders.
Which automobile car engine has three cylinders?
The Smart cars have three cylinder engines, as did some Geo cars.
What is more efficient diesel or petrol car?
diesel is more efficient
What happens to a car when when there are more cylinders?
A car that has more cylinders, unltimatley has more pistons inside of the cylinders so the create more energy in a shorter period of time, but they also would have a lower mpg because they use more gas as well.
How many cylinders does the Jaguar XK8 convertible have?
The Jaguar XK8 convertible model car comes with an 8 cylinder engine. Some car enthusiasts like to upgrade the XK8 with stronger engines but 8 cylinders is always what the car ships with directly from the dealership.
Hybrid Car Performance?
The key to hybrid car performance is the duel engine capacity. This make the gasoline engine smaller, allowing it to be much more efficient. Most cars rely on a large gasoline engine as their only power source, and the larger the gasoline engine the more problems arise. In the smaller gasoline engines found in hybrid cars, the engine requires smaller and lighter parts which reduces the number of cylinders needed to move the car.
What does 1.5 mean in vehicle engine specification?
The engines cylinders displace 1.5 liter. i.e. if petrol is the fuel for the car and not diesel
What car is more fuel efficient a Camaro or firebird?
What a ridiculous question. They are the same car!!!!! From 81 and up they have the same engines, weights, etc. Not to mention the cars have been built since 1967. What year are you wanting to know about?????????
