Internal Combustion Engine - Assignment Example Hence the internal combustion engine is the core component of any aircraft or car. The two-stroke and four-stroke engine are the most popular types of the internal combustion engine. It would be more feasible to first discuss the working of a four-stroke engine and then the working of a two-stroke engine, followed by its advantages and disadvantages. The cylinder is the core of the engine. The piston is a cylindrical piece of metal that moves up and down within the cylinder. There may be more than one cylinder present in different alignments based on the nature of the vehicle. The spark plug supplies the spark at regular intervals which is required to ignite the air/fuel mixture present inside the cylinder [2]. Two valves are present. The inlet valve allows the flow of air and fuel into the cylinder. The outlet valve allows the exhaust to flow out of the cylinder. The most important point is that both the valves must be closed during the process of compression and combustion so that the cylindrical chamber remains sealed [3]. The connecting rod is a piece of metal that connects the piston and crankshaft. Both the ends of the connecting rod can rotate so that its angle can be adjusted according to the motion of the piston and crankshaft. The up and down motion of the piston is converted into circular motion with the help of the crankshaft. The crankshaft is surrounded by a sump and engine oil gets collected in the sump.The four strokes include intake stroke, compression stroke, combustion stroke, and exhaust stroke [4]. Initially, the piston is at the top of the combustion chamber. First, the intake valve opens and this allows the piston to move down the cylindrical chamber. The descending motion of the piston allows the engine to take fuel (gasoline) and air inside the cylinder and the cylinder is gets filled with air and fuel. Air serves as an oxidizer for combustion. These events constitute the intake stroke.
