Everyone's saying it: The future of driving is electric. Of cars powered by internal combustion engines: Norway (by 2025), India (by. Starts with burning coal, for example, then how green is your electric car, really? The Union of Concerned Scientists has just crunched the latest numbers to find the answer.

Engines is certainly more logical because a distributive interpretation here is more logical. That is, each of the drivers has an engine, so there are plural engines.Literalists will argue that 'Drivers, start your engine!' Means that all of the drivers share a single engine. But this is not of course what the announcer meant.English (like all languages) is imperfect, and the people who speak it are imperfect, so little glitches with regard to distributive/non-distributive complements happen quite often. For example, I might say to my class, 'OK, folks, put down your pencil.' Or 'All of the students brought a toy for show and tell.'
And so on.But yeah, if you need a black-and-white answer, engines would certainly be more correct. But engine is not something to stew about as you watch those guys turn left (and turn left again) for the next few hours.
. What is the difference between a gasoline engine and a diesel engine? In a diesel engine, there is no spark plug.
Instead, diesel fuel is injected into the cylinder, and the heat and pressure of the compression stroke cause the fuel to ignite. Diesel fuel has a higher energy density than gasoline, so a diesel engine gets better mileage. See for more information.
What is the difference between a two-stroke and a four-stroke engine? Most and boat motors use two-stroke engines.
A two-stroke engine has no moving valves, and the spark plug fires each time the piston hits the top of its cycle. A hole in the lower part of the cylinder wall lets in gas and air.
As the piston moves up it is compressed, the spark plug ignites combustion, and exhaust exits through another hole in the cylinder. You have to mix oil into the gas in a two-stroke engine because the holes in the cylinder wall prevent the use of rings to seal the combustion chamber. Generally, a two-stroke engine produces a lot of power for its size because there are twice as many combustion cycles occurring per rotation. However, a two-stroke engine uses more gasoline and burns lots of oil, so it is far more polluting. See for more information.
You mentioned steam engines in this article — are there any advantages to steam engines and other external combustion engines? The main advantage of a steam engine is that you can use anything that burns as the fuel. For example, a steam engine can use coal, newspaper or wood for the fuel, while an internal combustion engine needs pure, high-quality liquid or gaseous fuel. See for more information. Why have eight cylinders in an engine? Why not have one big cylinder of the same displacement of the eight cylinders instead?
There are a couple of reasons why a big 4.0-liter engine has eight half-liter cylinders rather than one big 4-liter cylinder. The main reason is smoothness. A V-8 engine is much smoother because it has eight evenly spaced explosions instead of one big explosion. Another reason is starting.
When you start a V-8 engine, you are only driving two cylinders (1 liter) through their compression strokes, but with one big cylinder you would have to compress 4 liters instead.
