30/30, pretty weak quiz...

Yep,1 of the 3 answers are so bad even an idiotwouldn't use them. On the others one of the remaining two is a very poor choice.

29/30 for me. I never herd of Otto.

29/30 here, and Like Coby I dispute the spark plug question. Ignition noises are pings and clatter, usually induced by higher manifold pressure caused by going uphill; knocking is a bearing about to pack it up, usually a rod bearing. It will sound while idling in neutral and really get your attention under load.

29/30, I also missed the spark plug/low oil knock question...

30/30...very basic questions :dance1:

Basic for some folks.......I got 29/30 but my wife got 9/30........she knows all engines have tires and come with a key to start them........she also knows that if the engine doesn't work........you either call me or AAA.

Same score, same reason and although I got it right I thought power for radio etc etc came from the battery not the alternator, the alternator only charges the battery and my radio etc works without the engine running.

28/30. I missed the cylinder orientation and the cause of engine knocking. Despite owning a flat 4 engine on my wood splitter that term didn't register with me. I still think low enough oil is a way bigger problem than the wrong spark plug.

It probably does. The alternator isn't very clean power and goes through the battery to regulate it.

Yep,just a matter of simple deduction,30/30.
When I went through for the third time I deduced which answers they wanted even if they are wrong.:laughing:

Ever drive those old tractors that had an amp gauge instead of a voltmeter. When running you could see current go into (charge) the battery. Extra electrons from the alternator run other loads.
When turned off, you could see current leave battery for loads.
But don’t alternators creat AC power which is rectified by the voltage regulator? So in actuality the voltage regulator supples power?

I thought Otto was a transmission without a gear stick and Manuel was with a gearstick

29/30 Missed on the Otto

You're close,Otto has four on the floor and a fifth under the seat.

I correctly guessed the Otto one. I don't have a clue who he is and I've never heard that before.

From Wiki:

Nikolaus August Otto: 1832-1891. As a young man, Otto was a traveling salesman for a grocery concern. In his travels he encountered the internal combustion engine built in Paris by Belgian expatriate Jean Joseph Etienne Lenoir. In 1860 Lenoir succeeded in creating a double-acting (think: 2 cycle) engine which ran on illuminating gas at 4% efficiency. The 18 liter Lenoir engine was able to produce only 2 horsepower.

In testing a replica of the Lenoir engine in 1861 Otto became aware of the effects of compression on the fuel charge. In 1862 Otto attempted to produce an engine to improve on the poor efficiency and reliability of the Lenoir engine. He tried to create an engine which would compress the fuel mixture prior to ignition, but failed, as that engine would run no more than a few minutes prior to its destruction. Many engineers were also trying to solve the problem with no success.

By 1876 Otto (and Langen) succeeded in creating the first internal combustion engine that compressed the fuel mixture prior to combustion for far higher efficiency than any engine created to this time.

The "Otto cycle" is another name for, or rather describes the idealized thermodynamic properties (pressure, volume, temperature, entropy, etc..) of, the 4 cycles of a 4 cycle internal combustion engine.

It seems few Americans know the history of something as world changing as the gasoline engine. Could it be because it wasn't invented in America? But ask them who invented the car or the light bulb and they'd probably tell you Henry Ford and Thomas Edison!

Maybe Closer to- mass produced and Patented

Humphry Davy in 1800 ( light Bulb) ? And more than 1 american name referenced for the inventor of the car

Davy invented the Davy lamp which was a naked flame (wick) behind a gauze used in coal mines to reduce the chance of explosion from coal gas.
Henry Ford endeared himself to PD's with APB's, be on the lookout for a black Ford....
