Criteria On Diesel Engine And Emissions System Diagnostics

By Joshua Stevens


The emission system of a vehicle greatly reduces the harmful gases that are created by cars. It works together with the exhaust system so as to minimize pollutants and to ensure that the operations of the engines are efficient, quiet and clean. There are a number of problems that indicate problems in the system. The diesel engine and emissions system diagnostics allow you to know the faults to be looked into.

Look out for a number of signs that indicate the system is facing problems. For example, a lot of smoke being emitted from the exhaust indicates that there is a problem. It is suggested that you need to get off the road as soon as you see a lot of smoke, ask for assistance. This prevents the vehicle from being destroyed. Such an occurrence means that your engine has issues.

Reduced power is also another problem you should look into. A majority of the modern vehicles will automatically limit the engine speed when there is an issue. However, you can still drive the automobile as there will be no further damage done. The limp-home mode will be activated and is designed for you to get off the road or to your home safely. Components like Diesel Particulate Filter and catalyst converter are the major causes for this. In this case, your automobile requires immediate attention.

White powder coming from the exhaust is also another issue you should look into. It shows that the catalytic converter is has broken. Even though the damage will not be done if you drive a shorter distance, it has to be replaced as quickly as possible to avoid further problems. A catalyst converter is mostly constructed from ceramic material and the whitish powder seen means that the converter has been fractured.

Be keen on emission warning light displayed on your dashboard. The warning notifies you that the sensor is facing issues. Since the engine is facing problems, the warning will be displayed. Do not ignore this warning so that you avoid paying expensively for repair. The new exhausts include two sensors that can measure the current state of the exhaust gas. Any unusual signs experienced will be immediately displayed.

A rattling exhaust must also be examined. Since it will cause a lot of noise as you drive, the perforated metal piece, which is the most common cause of too much rattling and is due to corrosion. The immediate action you need to take is changing its back pressure. A catalyst converter or particulate filter converter failure can increase rattling. The failing device, therefore, needs to be replaced.

Poor engine performance is another issue that should be looked into. If it is not running optimally and there is a fuel smell from the exhausts, it indicates that the air-fuel mixture is not at optimum. Black smoke being emitted is not a good indication as the condition can cause damage to critical emission parts.

Ensure you do maintenance as required by your manufacturer. By doing this, you will not experience very serious issues. If you are attentive to important parts, repair done from time to time will not be expensive. This also ensures that one does not go through the reasons for failed emissions.
