Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:
ball joints |
|
bushings |
|
pins |
|
knuckles |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
The catalytic converter output consists primarily of:
oxygen |
|
water and carbon dioxide |
|
carbon monoxide |
|
gasoline |
The catalytic converter converts pollutants in exhaust gas into less pollutant substances like carbon dioxide and water.
The vehicle's computer system gets data from:
sensors |
|
regulators |
|
inhibitors |
|
actuators |
Sensors provide the data necessary for the vehicle's computer to make decisions and monitor everything from simple vehicle information like tire pressure to complexities like the chemical content of an engine's exhaust.
The fuel injectors are fed fuel by the:
electric fuel pump |
|
powertrain control module |
|
fuel pressure regulator |
|
fuel return line |
The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.
