Simple Engine Info Quiz

Explanation
The correct answer is every 3,000 miles. It is recommended to change the oil in your car every 3,000 miles to maintain the engine's performance and longevity. Over time, the oil in the engine gets dirty and loses its effectiveness in lubricating and protecting the engine parts. Regular oil changes help remove contaminants and ensure proper engine function. This interval may vary depending on the vehicle's make, model, and driving conditions, but 3,000 miles is a general guideline for most cars.

Explanation
The website describes two reasons that can contribute to engine overheating: not enough engine coolant and dust, bugs, or rocks jammed in the radiator.

Explanation
The opposed format and radial engine are the engine formats listed on the site that can be used for aviation. The opposed format refers to an engine design where the cylinders are arranged in two banks on opposite sides of the crankshaft. This design provides good balance and smooth operation, making it suitable for aviation applications. The radial engine, on the other hand, has cylinders arranged in a circular pattern around the crankshaft. This design offers high power-to-weight ratio and is commonly used in aircraft due to its reliability and ability to provide consistent performance at high altitudes.

Explanation
Nicholas Otto is the correct answer because he is the man who created an engine known as the "Otto Cycle". The Otto Cycle is a four-stroke combustion engine that is widely used in automobiles and other internal combustion engines. Otto's invention revolutionized the automotive industry and laid the foundation for modern engine technology.

Explanation
If the corrosion built up on the terminals of the battery is not taken care of, it can lead to poor electrical connections. This can cause the instrument lights to blink, indicating an unstable electrical current. Additionally, the corrosion can hinder the flow of electricity, resulting in a low charge in the battery. Eventually, this can lead to the inability of the battery to start the engine, resulting in a "no start" situation.

Explanation
The correct answer is Every 35,000 miles. Spark plugs play a crucial role in the ignition system of a car, providing the necessary spark to ignite the air-fuel mixture in the engine. Over time, spark plugs can become worn or fouled, resulting in reduced performance and fuel efficiency. By changing the spark plugs every 35,000 miles, the car's engine will continue to run smoothly and efficiently.

Explanation
The correct answer is Crank Shaft. The crank shaft is the component in the engine that keeps all of the pistons in line and connected as one. It converts the reciprocating motion of the pistons into rotational motion, which ultimately drives the wheels of the vehicle. The cam shaft, on the other hand, is responsible for controlling the opening and closing of the engine's valves, while the timing belt helps synchronize the rotation of the cam shaft and crank shaft. However, in this context, the crank shaft is specifically mentioned as the shaft that keeps the pistons in line and connected.

Explanation
The cam shaft is responsible for opening and closing the valves within a four-stroke format. It contains a series of lobes or cams that push against the valves, causing them to open and close at the appropriate times in the engine's cycle. This synchronized movement is crucial for the engine to function properly and for the intake and exhaust valves to operate efficiently. The crank shaft, on the other hand, is responsible for converting the reciprocating motion of the pistons into rotational motion, while the rocker arm helps transmit the motion from the cam shaft to the valves.

Explanation
The part that connects the piston head to the crankshaft is called the piston rod. This rod plays a crucial role in converting the reciprocating motion of the piston into rotational motion of the crankshaft. As the piston moves up and down, the piston rod transmits this motion to the crankshaft, which then converts it into rotary motion to power the engine.

Explanation
The general shape of the rotor within a rotary engine is a triangle. This is because a rotary engine, also known as a Wankel engine, uses a triangular rotor that rotates within an oval-shaped housing. As the rotor turns, it creates three separate combustion chambers, allowing for continuous combustion and power output. The triangular shape of the rotor is crucial for the engine's operation and efficiency.

Explanation
In a two-stroke cycle, the exhaust exiting and intake strokes happen simultaneously, meaning that as the exhaust gases are being expelled from the cylinder, fresh air/fuel mixture is being drawn in. This is different from a four-stroke cycle, where the exhaust and intake strokes occur separately. Additionally, in both the two-stroke and four-stroke cycles, compression and intake strokes happen, but in a two-stroke cycle, they happen simultaneously as well.
