What are the components of a semi truck?
Well, depends on how broad you're being. The most basic components are the power unit (tractor) and the trailer. If it's pulling double or triple trailers, there'll also be the converter dolly, which is used to link multiple trailers together.
Other than that, it's like any other road vehicle.. you have your drivetrain, you have your braking system, you have your electrical system, etc.
What is a good following distance if you are behind a tractor trailer?
You always want to ensure that you are far enough back that you can see the mirrors of that tractor - this also ensures that the driver can see you.
What newer model semi tractors get the best fuel mileage?
Either a Volvo with the D16 engine, or a shortnose conventional with a Cummins ISX engine. What gets you the best economy is having enough engine to deal with the problem. Trucking companies that put 400hp engines in their trucks force their drivers to turn 1500rpm to go fast enough to meet their schedules. Trucking companies that put 500hp engines in their trucks enable their drivers to run a few hundred RPM lower, which saves fuel. My company has a video starring an owner-operator who routinely gets 10.5mpg in his tractor-trailer. Needless to say, it's all about getting better fuel economy. He has great tips, but he isn't really admitting he's got a truck with a 600hp Cat in it. He just barely has to crack the throttle on that truck to turn 1200rpm, and he specified the rear end gearing so he can do 55mph at 1200. This still doesn't change the fact the guy's the king of fuel economy and a hero to one and all. It does show that your trucking company can do a lot to help you get good fuel economy, and good companies are starting to realize this-it doesn't cost much more to get a big-enough engine, and it doesn't cost ANY more to put the right gear in it.
What size engines do lorrys have?
11 - 16 litres. From what I've seen of HGVs in the EU and UK, company fleets seem to stay in the 12 - 13 litre displacement range, while owner/operators gravitate more to the 14 - 16 litre motors.
You can. There's a provision in the hazmat regulations that allows you to carry a small amount of hazardous material necessary for the operation of the truck without filling out a hazmat bill of lading for it. I wouldn't carry the cylinder in your sidebox, though; if it leaks the propane will go right into your cab. (You would need to provide a box for the cylinder. You are not actually allowed to carry ANYTHING on your catwalk per DOT regulation.)
When should the locking pin on an articulated loader be utilized and why?

Does a recovery vehicle with a full air brake system require a tractor protection valve?
If it's an on-road vehicle manufactured during or after 1975, then yes, it must. It must also have a dual circuit air system, in accordance with FMVSS 121.
On a related note, a lot of drivers seem to think the tractor protection valve is the valve which releases the spring brakes on the power unit, and pokes through the dash with a (usually) yellow knob - it is not; that is the brake control valve, which must also be present.
yes
adjust them so there is a half inch of free travel when not applied i wouldn't go by the travel when they are applied because you have 120psi pushing them out, you could adjust them to tight
What type of oil international tractor?
That's going to depend on what kind of climate you're operating in. 15W-30 or 15W-40 is what's typically used as a general purpose, all-around oil type. Some people swear by Shell Rotella T. Personally, I'm more partial to Mobil Delvac.

They are the adjusters on the rear drum brakes.

'After adjusting that way and after you remount the tires, , back the car up , in a straight line a few times to set them automatically and to the correct tension.
