Dr. Robert Gaspar is one of the geniuses behind today’s vehicles. Let’s take a close look at automotive engines to understand how cars function.
The Automotive Engine
Dr. Robert Gaspar explained that an automotive engine is also known as internal combustion engine that is designed to use small, controlled explosions and create the required power to move the vehicle. Internal combustion engine is being used in lawnmowers, motorcycles and other motorized devices.
Throughout the years, improvements on the design have been made to improve efficiency and power making sure that the needs of vehicle users is met.
Automotive engines use a four stroke combustion cycle namely the intake, the compression, the combustion, and the exhaust. According to Dr. Robert Gaspar, these 4-stroke combustion cycles are used repeatedly in quick succession to generate power and all of their parts take place within an enclosed car engine.
To give a more defined idea of how car engines work, Dr. Robert Gaspar used a windmill as an example. The arms of the windmill use the force of the wind to be moved and as the wind moves the arms, the windmill is able to generate power that can be used to move heavy grinding stones or create electricity.
The automotive engine works in the same manner. It uses small, controlled explosion that enables the piston of the engine to move. Once the energy from the explosion dies down, another explosion happens, forcing the pistons to create movement once more. This recurring cycle generates the power needed to create movement.
Dr. Robert Gaspar further noted that the piston is a metal rod connected by a crankshaft to a connecting rod. During the intake cycle, the intake valve opens causing the piston to move down, thus starting the cycle. The motion of the piston causes air-filled cylinder and a small amount of gas to enter the engine.
In the compression cycle, the piston moves up and decreases the space of the air and fuel. The smaller the space, the more powerful the explosion so it is important to make sure that the seal on this space is airtight to avoid energy loss.
On top of the cycle, the spark plug produces a spark that ignites the gasoline. Dr. Robert Gaspar explained that the power of the explosion forces the piston down and if the spark does not occur at the proper timing, the explosion will not take place.
At the last stage of the stroke, Dr. Robert Gaspar said that an exhaust valve opens up so that gas wasted from the explosion can leave the engine. Through the pressure of the recurring explosions to the catalytic converter and muffler gas is moved downwards. The air is freed of larger pollutants and the exhaust leaves the vehicle through the tailpipe.
Dr. Robert Gaspar also noted the important role of the speed of the cycle because it also determines the speed of the vehicle. He explained that as the driver puts more amount of gas into the engine, there is also increased movement on the engine pistons resulting in a faster pace that causes increase in the speed of the combustion cycle.
Lastly, the spark plug is another important component that plays a critical role in the automotive engine. As to what its name suggests, it creates a spark that initiates the explosion and designers of spark plug with the help of researches done by majestic automotive engineers like Dr. Robert Gaspar continues to try to create valuable improvements. By creating more sparks within a short period of time, the engine is also able to achieve greater speeds.
