A diesel engine has several other name variations, and a compression ignition engine is one of them. This can also be shortened to CI engine.

1. True
2. False

Rudolf Diesel did invent the diesel engine during the late 1800s. The diesel engine also came after the steam engine.

1. True
2. False

True. A medium-sized diesel engine can produce up to 1,006 horsepower. You can find these engines on many types of trucks.

1. True
2. False

False. Diesel engines actually run on two OR four-stroke cycles. Depending on which type of engine you have, certain nozzles and valves may be found in the cylinder head.

1. True
2. False

False. Large diesel engines are not available for cars, but they are used for big machines like trains and ships. They can also produce well over 1,000 horsepower.

1. True
2. False

True. While diesel engines are considered to be an efficient type of engine, they do release many pollutants into the air. This includes compounds that contain nitrogen and soot.

1. True
2. False

True. Both of these words refer to the same type of engine, which contains 4 cylinders. These cylinders are also built next to each other, hence the name "straight-four."

1. True
2. False

False. This engine actually has 4 cylinders, which is an ode to its name "inline-four." You can also find this type of engine in many economy cars.

1. True
2. False

True. You'll find many types of tractors using a large inline-four engine. This engine has also been utilized in past racing vehicles.

1. True
2. False

True. You'll find many types of cars using a four-cylinder engine. The V6 engine is another popular type of engine that can be found on many vehicles.

1. True
2. False

True. There are 6 cylinders in a V6 engine, which can be found on the crankshaft. These are very versatile engines, built for speed, power or even economy.

1. True
2. False

False. You'll find most cylinders manufactured at a 90-degree angle, with some at 60 or 120 degrees. This number never drops to 30, but has been as low as 45 degrees.

1. True
2. False

True. Since V8 engines can be expensive, some people swap to a V6 engine since it will fit in the same compartment. This is due to the size and standard 90-degree angles.

1. True
2. False

False. The displacement range of most V6 engines is actually 2-4.3 L. Although this is considered to be the standard, some engines have also been manufactured with a higher displacement range.

1. True
2. False

False. The cylinders of a V engine are shaped like the letter "V," hence the name V engine. This allows for a smaller and more efficient type of engine compared to many others.

1. True
2. False

True. In 1888, the V engine was invented thanks to the great minds of Gottlieb Daimler and Wilhelm Maybach. There are currently many types of V engines on the market, including V8 and V12 engines.

1. True
2. False

False. V engines are actually considered to be a compact type of engine, especially when compared to a straight-four engine. This is because a straight-four has all of the cylinders lined up together, while a V engine has its cylinders placed in a V-shape.

1. True
2. False

True. The number of cylinders in the engine depends on the number you see after the "V." For example, a V12 engine will have 12 cylinders.

1. True
2. False

False. These are two very different types of engines. The V4 engine has 4 cylinders that are in the shape of a "V," while an inline-four engine has its 4 engines in a single row.

1. True
2. False

True. A V4 engine can be utilized with an outboard motor, which is used by boats. This type of engine can also generate well over 140 horsepower.

1. True
2. False

False. V8 engines actually have a very large displacement, with some as high as 8.5 L, or more. Some do have less than 4 L, but it's very rare.

1. True
2. False

True. Léon Levavasseur is responsible for creating the V8 engine. He also nicknamed the engine "Antoinette."

1. True
2. False

True. A V10 engine is used in many sports cars and Formula One vehicles, due to its 10 cylinders and large horsepower output. It can also be found in a Dodge Viper and a Lexus LFA.

1. True
2. False

True. No balance shafts are needed for a V12 engine since it features two sets of 6 cylinders on each side. This is also similar to an inline-six engine.

1. True
2. False

True. An inline-six engine consists of 6 cylinders in a single file row. This is also called a straight-six engine.

1. True
2. False

False. These are two different types of engines. The Wankel engine is actually known as a rotary engine, and rotates using transferred pressure.

1. True
2. False

True. A Wankel engine is much smaller than a piston engine, but is just as (if not more) powerful. However, these engines are not great for fuel economy cars.

1. True
2. False

False. An inline-four engine consists of four cylinders that sit next to each other in a single file row. A flat-four engine does have four cylinders, but each set of 2 cylinders are on the opposite sides of each other.

1. True
2. False

True. The size of the petrol engine varies depending on the industrial or commercial application at hand, but there are certainly many uses of the petrol engine. These are also found in motorcycles and cars.

1. True
2. False

True. There are 4 stages of an engine stroke, which are intake, compression, combustion and exhaust. This method is for four-stroke engines.

1. True
2. False

True. You'll find air-cooled engines in many motorcycles and aircraft. Hot air is usually circulated via a fan or cooling device to cool down the air for re-use.

1. True
2. False

False. A radial engine is actually known as a star engine due to its star-shaped aesthetics. It can be found in many types of aircraft and tanks.

1. True
2. False

False. Radial engines actually consist of short crankshafts, which enhances durability and longevity. This type of crankshaft is also much quieter, and won't vibrate as much.

1. True
2. False

False. A flat-twin engine only has 2 cylinders and is considered to be a type of internal combustion engine. It has also been found in boats, motorcycles and airplanes.

1. True
2. False

True. A flywheel is used to move a piston to the "top dead center" of an engine. Other parts of a reciprocating engine includes spark plugs, an exhaust camshaft and the connecting rod.

1. True
2. False

True. Many small industrial appliances, such as generators and pressure washers, utilize a V-twin engine. This also consists of two cylinders.

1. True
2. False

True. Russell Bourke did "invent" the Bourke engine, but unfortunately, it never hit the shelves. The design was left unfinished due to a multitude of factors, including WWII.

1. True
2. False

True. Tanks and trains utilize gas turbine engines, which are also known as combustion turbine engines. These engines can also be found on airplanes and large boats.

1. True
2. False

False. These are two different types of engines. A steam engine utilizes steam pressure to make its moving parts work. It was also invented by Thomas Savery.

1. True
2. False

True. These were two very important parts of a steam engine. The boiler was used to heat up the water, while the cold sink was used to get rid of the steam.
