Bottom-End |
Engine block assembly
including crankshaft and pistons, but not the cylinder head. |
| Cam Shaft |
Opens the valve to each
cylinder. |
| Cat-Back |
Exhaust system from the
catalytic converter back, includes B-pipe, resonator and muffler. |
| Catalyst
Converter |
Emission device in exhaust
system used to convert hydrocarbons into harmless substances. |
| Crank Shaft |
Connecting rods attach to
this. Uses piston linear motion + converts it to reciprocal motion. |
| Differential |
Transmits engine reciprocal
motion to wheels via ring + piston gears. |
| Down Pipe |
Pipe from exhaust manifold to
catalytic converter. |
| Exhaust Valve |
Tulip shaped metal component
that opens via camshaft to let exhaust gases escape combustion chamber. |
| Exhaust/Muffler |
Usually a sheet metal series
of baffles used to quiet the exhaust system. |
| Header |
A free flowing replacement for
the exhaust manifold. |
| Intake Valve |
(see exhaust valve) Opens to
intake manifold. |
| Intake/Air
Filter Sys. |
System that lets air into the
engine for the combustion process, cleaning the airstream with a filter. |
| Intercooler |
Radiator-like device used to
cool the intake air by exchanging heat to the surrounding area. |
| Oilcooler |
Radiator-like device used to
cool oil (see above). |
| Supercharger |
Forced induction, usually
using a belt driven pump to compress intake air above normal atmospheric pressure. |
| Throttle Body |
In fuel injected motors, the
component that controls air flow into the motor usually with a throttle plate. |
| Top-End |
Part of the engine from the
block-up, includes cylinder heads and cams. |
| Turbocharge |
Forced induction using an
exhaust-heat driven turbine and compressors. |
| Valve-Spring |
The spring that returns the
valve to its static position. |
