What is ic engines11/9/2022 ![]() Swept volume= Volume of piston traversed as it completes one full stroke from the TDC to BDCĬlearance volume= Volume of the combustion chamber, when piston is at TDC Also, a higher compression engine tends to have less clearance between the piston at top dead center(TDC) and the valves fully opened, and running at a high rpm can lead to valve float which can leads to contact between the valves and piston.Ĭompression Ratio= (Swept volume + Clearance volume)/Clearance volume One of the limiting factors in increasing the compression ratio is called detonation (known as engine knocking or pinging) where instead of burning in a controlled fashion, the air/fuel mixture explodes, potentially damaging the engine. ![]() The more air that is squeezed into the combustion chamber the more energy is produced per engine capacity on the expansion stroke. An engine with a compression ratio of 12:1 means that for every 12 unit volume of air that is sucked in, the piston squeezes that air to a 1 unit volume. The compression ratio basically tells how much the engine squeezes a certain volume of air that it intakes. This is the bottom most part the piston can reach in an vertical engine.Īn internal combustion engine is basically a pump which squeezes an air/fuel mixture (or just 'air' in the case of direct injection engines) and then ignites it so that it expands back and produces the mechanical energy. This is the top most part the piston can reach in a vertical engine.īDC: Bottom Dead Centre. In the two stroke, there are just two cycles and each of them having two cycles running concurrently. ![]() Also the engines can also be classified on what cycles they follow, given belowįour stroke engines, as the name suggests, have totally four different cycles, namely ![]()
