Petrol engine
Petrol engine. Computer artwork of an internal combustion engine cylinder. The piston (lower right) is moved up and down by the combustion (burning) of fuel. At the beginning of the cycle, the intake valve (left) opens, allowing fuel into the chamber. The piston moves down, drawing in air and fuel vapour. As the piston returns, this is compressed and ignited by the spark plug (upper left). The resulting explosion drives the piston back down for another cycle. The exhaust valve (upper right) opens to vent waste gases as the piston returns again. Diesel engines use compression, rather than a spark plug, to trigger combustion

EDITORS COMMENTS
This print showcases the intricate workings of a petrol engine, beautifully depicted through computer artwork. At its core, an internal combustion engine cylinder takes center stage, with the piston positioned in the lower right corner. The rhythmic up and down motion of this piston is driven by the powerful combustion process that occurs when fuel ignites within the chamber. The cycle begins as the intake valve on the left side opens, allowing a precise mixture of fuel and air to enter. As the piston descends, it draws in this potent combination of elements. With each subsequent stroke, compression occurs as the piston returns upwards while being ignited by a spark plug located in the upper left corner. The resulting explosion propels the piston downwards once more, initiating another cycle. Waste gases are then expelled through an exhaust valve situated on top-right as part of this continuous process. It's important to note that diesel engines differ from their petrol counterparts by utilizing compression rather than spark plugs to trigger combustion. This stunning illustration not only highlights key components such as cylinders and valves but also emphasizes how engineering marvels like these power our vehicles and contribute to advancements in transportation technology. It serves as a testament to human ingenuity and innovation within both mechanical and energy sectors.
