Internal Combustion Engines
Original Message   Mar 20, 2005 6:09 pm
A few of you may know that I'm a leader in 4-H for the small engines project in our club.  Here's some of the questions I'm asking the 12-18 year old this year.  There are 3 girls and 2 boys this year.  Let's see how you guys/gals stack up.

1.     T or F     An engine is a machine that converts a form of energy into mechanical force.

2.     Small engines are generally rated up to _______ HP.  A) 20     B) 25     C) 30     D) neither A, B or C

3.     Approximately ______% of the energy relaesed when fuel is oxidized in a typical small engine is converted into useful work.

4.     T or F     Heat is the resource that provides the capicity to do work.

5.     T or F     A substance can be in solid, liquid or gas state.

6.     Three methods of heat transfer are ______.     A) conduction, convection and locomotion     B) conduction, radiation and locomotion     C) conduction, convection and radiation     D) neither A, B or C

7.     Horsepower is a unit of power equal to _____.     A) 746W     B) 33,000 lb-ft/min     C) neither A or B     D) either A or B

8.     T or F     Both 4 stroke and 2 stroke engines complete 4 distinctive events during each cycle.

9.     T or F     Small engines are either air-cooled or liquid-cooled.

10.     When heat is added to water, it changes to ________.

11.     T or F     Generators and snow throwers commonly use a verticla shaft, horizontal cylinder engine.

12.     The first successful gasoline engine was developed by _______.     A) Thomas Savery     B) Eugene Lebon     C) James Watt     D) Neither A, B or C

13.     T or F     Kinetic energy is energy of motion.

14.     T or F     Small engines are either spark ignited or compression ignition based on how the fuel is ignited.

15.     When heat it added to ice, it changes to ________>

16.     T or F     The size of lawn tractor engines commonly range from 11 to 18 HP.

Let's see how you do and I'll post the answers later this week.

Hey Marshall,

Good find.  The Briggs book isn't exactly laid out like that, but it's close.  Do they have more of those pages?

I'll have to post some of the MST (master service technician) questions.  They baffle me, but Chris is a Master Tech, one of the few around here.  Go figure.

Rob,

You did very well.  12 out of 16. 

2.     2) 25HP

3)     30%

7)     D) either A or B

12.)     B) Eugene Lebon

Those seem to be the ones that trip up everyone.  It's still early here or I'd post all the asnwers together - but they can just read yours and then read this one.

Congrats on being brave.

Miss SS,

Just some thing to think about on your questions.

When you have enough BTU"s you will change water to steam, otherwise just hot water!!! I hope you don't get burned  when you take a shower. Rember you have added heat to the water in your water heater, but no steam!! Question should be rewritten. Same with #15. go from a temp of 30 below to 10 below, you have added heat, but you still have ICE!

Fred you are right about adding heat to water, but if I go from 30 below to 10 above, I'm gonna have water (Canada = celcius).
