Automotive Engines
Unlike the basic one-cylinder engine just discussed,
automotive engines are multi-cylinder engines, which
means they have more than one piston and cylinder.
Vehicles commonly have 4-, 6-, 8-, or 10-cylinder
engines. The additional cylinders smooth engine operation
because there is less time (degrees of crankshaft rotation)
between power strokes. Additional cylinders also
increase power output.
An actual automotive engine is pictured in
Figure 1-10. Study the shape, location, and relationship
of the major parts.
