What is engine structure?

Structure Of The Internal Combustion Engine. … The most basic components of the internal combustion engine are the cylinder, the piston, and the crankshaft. To these are attached other components that increase the efficiency of the reciprocating motion and convert that motion to the rotary motion of the crankshaft.

Is the engine block the main structure of the engine?

The engine block is the main structural component of an engine. It supports and helps maintain alignment of internal and external components. The engine block consists of a cylinder block and a crankcase. An engine block can be produced as a one-piece or two-piece unit.

What is the most important part of an engine?

What is the basic principle of engine?

In a spark ignition engine, the fuel is mixed with air and then inducted into the cylinder during the intake process. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
