One of the more crucial elements of a car is the exhaust system. It contains various parts, playing a vital role in reducing emissions and environmental damage. The EGR valve is an essential component, but what
The next fix you can try is to shut off the engine and let it rest for at least 5 minutes. During this time you can check the engine oil level, as well as the level of all the other fluids under the hood. Sometimes, this brief rest will allow the computer to reset itself and bri...
What to expect from EGR: later this year, most new diesel engines will begin using exhaust gas recirculation to curb emissions. Learn how EGR works and how it will affect you on the road and in the shop.(Cover Story)(Brief Article)...
3. Blocked EGR valve The exhaust gas recirculation (EGR) valve helps to lower emissions. In diesel cars, it is prone to blockages due to built up carbon deposits, which are created when the vehicle does too many short journeys. The valve needs cleaning or replacing, after which you can ...
The EGR vacuum will not operate if the power control module does not signal the solenoid to switch it on. Also, faulty wiring of the solenoid can cause over-stimulation of the vacuum, creating a stronger suction than needed. As a result, the EGR valve may become clogged or open too widel...
gasoline combustion (LTGC) engine [23], [24], [25], [26], a gasoline direct injection spark-ignition (DISI) engine [27], an EGR-diluted DISI engine [28,29], a Cooperative Fuel Research engine [30], several light-duty diesel engines [30], and a heavy-duty diesel engine [31]. The...
Not only does this last stage help the engine’s overall efficiency, it also allows the engine to provide the cat with enough oxygen to effectively complete the oxidisation process with the second catalyst. So what is a sports cat? A sports cat manages to do everything a standard cat can...
If it does NOT start, it probably has NO SPARK. TIP: Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a...
But dry fuels such as propane and natural gas don't cool or lubricate the valves like gasoline does, which means valve burning, wear and recession can be a problem if the engine doesn't have hard seats. Any engine that's designed to burn unleaded gasoline can handle propane without ...
Generally, the more your press the gas, the larger the opening of the air valve becomes. Allowing more amount of air in the engine. Velocity of the incoming air is just as important as the volume of air, and a throttle body allows the air to flow more easily into the cylinder. ...
