Engine FAQs:

Q: Was an engine invented?

A: Yes, and the term motor was initially used to distinguish it from the steam engine—which was in wide use at the time, powering locomotives and other vehicles such as steam rollers.

Q: Are engines also 40% more fuel efficient than comparable gasoline engines?

A: Yes.

Q: Are engines heat engines driven by the heat of a combustion process?

A: Yes.

Q: Are engines still often used in trucks and heavy machinery?

A: Yes, although they require special machining not available in most factories.

Q: Is an engine used for trucks and buses?

A: Yes.

Q: Was an engine unable to deliver sustained power?

A: Yes, but was useful for propelling weaponry at high speeds towards enemies in battle and for fireworks.

Q: Was an engine the first type of steam engine to make use of steam at a pressure just above atmospheric to drive the piston helped by a partial vacuum?

A: Yes.

Q: Is an engine often engineered much the same as an internal or external combustion engine?

A: Yes.

Q: Is an engine a device that burns or otherwise consumes fuel?

A: Yes, and changing its chemical composition, whereas a motor is a device driven by electricity, air, or hydraulic pressure, which does not change the chemical composition of its energy source.

Q: Is an engine the term used to define engines that are not used by vehicles on roadways?

A: Yes.

Q: Were engines commonly air-cooled and located at the rear of the vehicle?

A: Yes, compression ratios were relatively low.

Q: Are engines combustion engines that use the oxygen in atmospheric air to oxidise the fuel?

A: Yes, and rather than carrying an oxidiser, as in a rocket.

Q: Are engines fitted with mufflers?

A: Yes, newer turbofans often have outsized fans in order to reduce the proportion of noisy, hot exhaust from the integrated turboshaft in the exhaust stream, and hushkits exist for older, low-bypass turbofans.

Q: Is an engine an engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber?

A: Yes.
