What is engine and its types?

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. Most of these are six - stroke cycle engines, meaning six piston strokes are needed to complete a cycle.

What are the engine characteristics?

Basic design and performance parameters in internal combustion engines include compression ratio, swept volume, clearance volume, power output, indicated power, thermal efficiency, indicated mean effective pressure, brake mean effective pressure, specific fuel consumption, and more.

Engine performance

Engine performance is often characterized by the engine operating behavior in the speed–load domain, for example, the behavior of emissions, fuel consumption, noise, mechanical and thermal loading. Engine performance maps refer to the constant value contour plots of a given performance parameter in the speed–torque domain. A good understanding of engine performance maps is important to a system design engineer.

For an engine equipped with fixed-geometry hardware without flexible controls, such as,  fixed-geometry turbine, mechanical camshaft, mechanical water pump, optimum system performance is a large compromise between high-speed and low-speed operations, or between high-load and low-load operations. The trade-off effect is especially prominent when the range of the engine speed or load is wide. Mapping the operating characteristics of engine customer applications, for example, vehicle driving cycles, marine engine load cycles to the engine speed–load map and mapping the engine speed–load characteristics to the component characteristic map are two important design techniques for a system engineer in conducting system integration. 

What is the most important part of an engine?

Flywheel: Flywheel is one of the most important engine components. It is a large and heavy metal wheel. Flywheel is attached to the back of the crankshaft to smooth out the firing impulses.
