Best Diesel Exhaust Fluids

What are the most common causes of engine failure?

The cause of engine failure is a combination of several factors. Engine failures are usually caused by one or more of these reasons:

Improper maintenance practices – Improperly maintained engines tend to fail sooner than properly maintained ones. For example, improper oil changes may lead to premature wear out and possible catastrophic engine damage.

Poor fuel quality – Poorly refined fuels such as kerosene and unleaded gasoline may not provide sufficient lubrication to prevent engine damage.

Excessive use of catalytic converters – Overuse of catalytic converter (CC) systems can result in poor combustion efficiency, resulting in higher emissions of harmful pollutants. CC systems are designed to reduce the amount of harmful pollutants released into the atmosphere when a vehicle’s tailpipe is ignited with regular fuel. However, they can become clogged with debris and deposits from road grime, dirt, dust and other contaminants. If left unchecked, this buildup can eventually block the system completely.

When this happens, it will no longer function properly and the vehicle may emit excessive amounts of harmful pollutants.

Engine overheating – Heat builds up inside an engine due to various factors including engine running at high speeds under load conditions or idling for extended periods of time. Also, the use of bad quality coolant can increase the chances of engine overheating.

Worn out gaskets and seals – Gaskets and seals are designed to prevent the escape of compressed gases. As these gaskets and seals age, they lose their ability to perform their intended purpose. Once this happens, the escaping gases may no longer be contained within the combustion chamber. These escaping gases carry heat away from the combustion chamber.

As a result, more fuel is required to be injected into the chamber in order to produce the necessary heat to ignite the fuel-air mixture.

How should I handle my diesel’s exhaust system?

The exhaust system plays an important role in the overall efficiency of your vehicle’s engine.
