With 35 horsepower, the 1901 Mercedes was able to reach 53 miles per hour.

1. time required to heat the boiler
   not competitively priced
2. frequent stops to refill the water tank
   all of the above

Once in favor over gasoline-powered internal combustion engines, steam lost popularity because it was high maintenance.

   coal dust
2. kerosene
   steam

Oliver Evans filed the patent on the first steam-powered land vehicle.

Richard Trevithick's steam-powered "road carriage" was built in the U.K. (Great Britain).

   1904
2. 1919
   they never did

The Studebaker brothers entered the automobile business in 1902, when they began manufacturing electric-powered automobiles. It wouldn't be until 1904, though, that they'd make their move into gasoline engine-powered cars.

1. butanol
   dimethyl ether
2. gasoline
   synthetic diesel

Hock's engine was gasoline powered.

1. injector
   spark plugs
2. turbocharger
   water jacket

Oliver Lodge patented the spark plug; an electric spark ignition for the internal combustion engine.

1. Carl Benz
   Gottlieb Daimler
2. Nicolaus Otto
   Ferdinand Porsche

Carl Benz received German patent DRP No. 37435 for a "vehicle with gas engine operation."

1. Eugenio Barsanti
   Karl Benz
2. Rudolf Diesel
   Jonathan Hornblower

Carl Benz invented a three-wheeled vehicle powered by an internal combustion engine.

1. Gottlieb Daimler
   Duryea Brothers
2. August Horch
   Nikola Tesla

Just a few short years after Carl Benz made the first three-wheeled vehicle with an internal combustion engine, Gottlieb Daimler built the first with four wheels, adapted from a stagecoach. Today this is considered the first modern car.

1. wax fuel
   jet fuel
2. fuel oil
   coal oil

Delamare-Deboutteville invented an engine that ran on fuel oil rather than gasoline, and the wick carburetor needed to use it.

America's first gasoline-powered automobile was the three-wheeled Lambert car, invented by John W. Lambert.

1. cars with diesel-fueled internal combustion engines
   cars with mineral spirit-powered internal combustion engines
2. cars with fusion-powered internal combustion engines
   cars with gasoline-powered internal combustion engines

The Duryea brothers began manufacturing commercial cars with gasoline-powered internal combustion engines in the late 19th century.

1. a diesel-powered internal combustion engine
   an electric-powered internal combustion engine
2. a gasoline-powered internal combustion engine
   a kerosene-powered internal combustion engine

In 1899, Olds opened the Olds Motor Works in Detroit, Michigan, where he started manufacturing the popular Curved Dash Oldsmobile, with a gasoline-powered internal combustion engine, in 1901.

1. boxer engine
   opposed-piston engine
2. V-type engine
   W-type engine

Carl Benz invented the boxer engine, also known as a flat engine. What makes the boxer engine different are its horizontally-opposed cylinders.

1. a battery
   charcoal
2. coal gas
   wood pellets

Étienne Lenoir's engine was powered by coal gas.

1. connecting rods could be shut down
   cylinders could be shut down
2. spark plugs could be shut down
   valvetrain could be shut down

The 1917 Enger wasn't the first to do it. Nor was the 1981 Cadillac V8-6-4 engine. But in the Sturtevant 38-to-45 horsepower six-cylinder engine, three of the six cylinders could be shut down.

1. gasoline was injected through a carburetor
   it could run on more than one fuel
2. it had a high chassis
   it was the lightest weight engine available

The Model T's internal combustion engine was a "multifuel" engine (which today we know as a flex-fuel engine), and it could run on gasoline, kerosene, benzene, ethanol and others -- but it wasn't, as it's often believed, designed to do so.

1. the Newcomen steam engine
   a steam beam engine
2. a turbine engine
   a two-cylinder high-pressure steam engine

Lenoir's gasoline-powered internal combustion engine closely resembled a steam beam engine, but with the cylinders, connecting-rods, fly wheel and pistons of the internal combustion engine.

1. a four-stroke compressed charge engine that didn't work
   a four-stroke compressed charge engine that did work
2. the first successful atmospheric engine

1. Buick Auto-Vim and Power Company
   Dodge Brothers Company
2. Ford Motor Company
   Packard Motor Car Company

The Packard Motor Car Company produced a "Twin Six" model, which was a 12-cylinder engine. It was the first to use what today we call a vibration dampener.

1. clogged fuel injectors
   cracked engine block
2. engine knocking
   stalling

Engines would knock and vibrate when engineers increased compression ratios because the fuel octane at that time couldn't handle the high heat and pressure.

1. one-quarter
   one-third
2. one-half
   almost all of them

About 1,050 (one-quarter) of the almost 4,200 U.S.-built cars on the roads in 1900 ran on electric motors.

1. aluminum-block engines
   iron-block engines
2. magnesium-block engines
   titanium-block engines

Haynes is responsible for the development of several alloys, including chromium, cobalt and tungsten. He also discovered stainless steel. But his work also led to aluminum's use in automobile engines.

1. 5 percent
   25 percent
2. 50 percent

Rudolf Diesel's internal combustion engine was 75 percent more efficient than its contemporary steam engines, which could boast just 10 percent efficiency.

1. 127 mph

2. Knox Automobile Company
   F. B. Stearns & Company

When Henry Ford, founder of Ford Motor Company, refused to pay licensing fees, he and Selden went to court. In the end, Selden was forced to build his "road machine," which was a failure, and the patent was null.

2. petrodiesel
   synthetic diesel

Rudolf Diesel demonstrated his diesel engine with peanut oil as fuel.
