Exhaust and Emission system
Hanger and clamps
Exhaust clamps and hangers are used to connect and suspend the exhaust system components under the body of the vehicle
Exhaust components
Exhaust manifolds, Exhaust pipes, Muffler, resonator, Exhaust gaskets and seals, Hangers and clamps
Exhaust gas recirculation
When open it reroutes a small amount of inert (chemically inactive) exhaust gas to the intake manifold
electricity design
(CV) engine
Gas design
(ICE) engine
Catalytic converter
A TWC contains a catalyst that when very hot accelerates the chemical change of CO, HO and NOx into vapor(H2O), CO2 and nitrogen
Exhaust gaskets and seals
A gasket or seal ring ( also known as a donut) may be used where exhaust parts are joined to prevent exhaust leaks
Resonator
A resonator helps absorb additional sound vibrations in critical areas of the exhaust system
EVAP/charcoal canister
An evaporation emission control canister also known as a charcoal or carbon canister is used in the emission system to store hydrocarbons fuel vapors from the fuel tank
Muffler
It is basically a silencer to aid in the reduction of noise pollution and is located after the catalytic converter, but before the tailpipe
powertrain control module
The PCM receives input from sensors and then provides accurate and immediate commands
Positive crankcase ventilation
The PCV valve commonly located in the valve cover with a hose connecting it to the intake manifold, reduces HC and CO (blow by crankcase emissions)
Exhaust and emission purpose
The exhaust and emission system is designed to deal with the inefficient by products of the internal combustion process
Exhaust pipes
The intermediate exhaust pipe, connects the catalytic converter to the muffler
biodiesel and propane fuel are not alike
biodiesel vehicles cost more than a propane vehicle
biodiesel and propane fuel are alike
both biodiesel and propane vehicles are on the road
electricity advantages
can fit into small spaces,
electricity disadvantages
can not go as for with out changer for a long time
hybrid advantages
can use gas or electricity, can go very fare
hybrid design
gas and electricity engine
gas advantages
it can go fare, it is fast to put in
Exhaust manifolds
it harnesses the hot exhaust gases from combustion and guides them to the exhaust pipes.
Oxygen sensors
it send signals to the PCM to maintain a 14.7 to 1 (stoichiometric ratio) air-fuel ratio
gas disadvantages
kills the plant
hybrid disadvantages
to much money
