Emission Control Systems in Automobiles

When we think of car emission control systems in automobiles work, we usually think of dark smoke or fumes coming out of our exhaust pipes. While we drive, internal combustion processes create noxious chemicals (like CO2 and nitrogen oxides) and get released into the air. But tailpipe emissions are now controlled using a number of systems like catalytic converters...

ECU Components in Automobiles

Before today's emission laws, you could build a car engine with no microprocessors. However, we now have stricter emissions laws, so sophisticated controlling mechanisms (ECU Components and Engine Controls) were necessary to control the air/fuel mixture in order for the catalytic converter to reduce the pollution from our exhaust. (Look at How Catalytic Converters Work for further explanation.)

Automotive Electrical Design

All the different modules send this information onto the communications bus and, several times a second, the ECU sends out information containing a header and the data. The header is simply a number that identifies the data as either a speed or temperature reading while the data is the actual speed or temperature. Another module on the instrument panel...

Wheel Alignment Basics FWD RWD and 4X4

“Alignment” is not just one part of your car. The alignment is actually a complex subject that includes a variety of terms and interrelated parts. When your tires are out of alignment, it means the wheels and the parts controlling them aren’t facing the correct angle to work properly. This affects steering, suspension, and can rapidly wear down tires....
