Emission Control Systems

Emission Control Systems, limit the release of harmful gases from your engine into the atmosphere. This includes hydrocarbons, carbon monoxide, and oxides of nitrogen.

The 3 main sources are, Crankcase, Evaporative (EVAP) and Exhaust. These are in place to track and control the emissions, and air/fuel ratio in a vehicle’s engine.

The parts of the system include the catalytic converter, positive crankcase ventilation (PCV) system, exhaust gas recirculation (EGR) valve, evaporative controls, and air injection.

Common reasons your Check Engine Light (CEL) might come on is for an Emission Control Systems Fault. This is when the engine is burning too much fuel, increasing your carbon footprint. The (CEL) could also come on, because your not burning enough fuel, or if the sensor is broken.

PCV Valve System: This Is Where Crankcase Gases Get Recycled

08/27/2024

So, the PCV valve system, is one of the oldest and most used emission control devices, in today’s engines. And, although its name might sound very complicated, it is a very simple device. The PCV Valve […]

PCV Valve: How Does It Work, Failure Signs, How To Test It

08/26/2024

Knowing how the PCV valve actually works, is the first step in diagnosing a bad or failing one. When your engine is running, thousands of powerful explosions take place, to release the fuel energy. But, […]

Positive Crankcase Ventilation (PCV) System: What Does It Do

08/25/2024

First of all, the (PCV) System is the short form or common name, for the Positive Crankcase Ventilation (PCV) System. So, the Positive Crankcase Ventilation (PCV) system, is basically a one way passage. And, is […]

(PCV) Valve: Major Problems From Lack Of Regular Maintenance

08/23/2024

Replacing a (PCV) valve, isn’t difficult. But, sometimes accessing it can be a struggle, depending on your vehicle. So, most people don’t realize how important regular maintenance is, on your (PCV) system. And, then only […]

(PCV) System: One Of The Biggest Causes, Of Engine Oil Sludge

08/22/2024

Did you know the most common problem, in the (PCV) system, is a plugged up (PCV) valve. Another problem, is a lack of air flow, to carry vapors, away from the crankcase. Because, without air […]

Exhaust Gas Recirculation: Types, Failure, Cleaning, Replacement

08/21/2024

The exhaust gas recirculation (EGR) valve, does exactly what the name implies. It circulates, exhaust gas, for a second time. So, exhaust gas recirculation (EGR) valves, do not normally require maintenance. But, they can become […]

(EGR) Valve: Common Problems And Troubleshooting Procedures

08/20/2024

The (EGR) valve system, is designed to help minimize, harmful oxides of nitrogen in the air we breath. To help do this, the (EGR) valve allows, a calibrated amount of exhaust gas, to reenter the […]

Loose Gas Cap: Most Common Cause For A Check Engine Light

08/14/2024

So, a loose gas cap is among the many causes, for a (CEL) check engine light to come on. In fact, a loose gas cap, is actually the most common cause, of a (CEL) check […]
