The modern designs of engines have cut off most of the factors that usually cause engines to develop faults regularly, such includes automatic fault detecting systems, diagnosis suggestions, digital indicators, etc.

All of these have made the engine repair and maintenance appear simple to some individuals, but the fact still remains that most mechanical engineers still find it difficult in carrying out repairs on these modern engines.

Though the attached mechanisms are good and will aid in fault detection what of the situation where the fault detector is the one having the fault alongside some parts of the engine?

How can the engineer know the source of the fault in such a condition?

These and many more questions have made it necessary to have a thorough knowledge of modern engines before working on any of them.

Engines: All You Need to Know About Them

Recently, a man complained to me about how his new jeep developed a vibration fault such that anytime his speed exceeds 80km/hr.

The motor will start vibrating while in motion, he took the vehicle to a mechanic who listed some items for him to buy because they need to be replaced.

At the end of everything, he spent more than N200,000 on the repair.

Though the sign stopped he realized after a few days that the sensors attached to the bumpers to automatically stop the vehicle from hitting nearby objects during turning had stopped working after the mechanic worked on the car.

Taking the car back to the mechanic he recommended buying new sensors and after their installations, the problem persisted till date, it is a very sad story I would say.

Modern engines use a pulley drive system which is mostly used with belts in their functions, and these belts do get weak over a period of time depending on the usage and quality.

Though this is a minor issue in engine maintenance its negligence had caused a lot of the wrong diagnoses in engine fault detection and repair.

When a weak belt develops its signals it may be wrongly detected by any digital devices to mean another thing which may lead to buying and changing parts that are not actually the real cause of the problem.

One way to avoid such an incident is to check for the specified period of time any belt in your engine is supposed to stay before changing it.

Some common faults weak belt could cause are;

IGNITION PROBLEM

This is one of the reasons you need to change your engine belts. The weak belt can cause a serious ignition problem because the pulley from the ignition motor needs to transmit a rotating motion to the engine flywheel or shaft at a high and instantaneous speed within a short time.

So if the belt had gone weak it will make the motor transmission speed be reduced such that if the engine ignition system is not in good condition the engine may find it difficult to start.

INCREASED OPERATING TEMPERATURE

Most engines use pumps to circulate the water from the radiator to the internal parts of the engine, the action is usually a continuous one provided the engine is in its operational state. This is one of the reasons you need to change your engine belts.

When the belt that drives the pump which is usually connected to the major engine shaft had gone weak or loosed, the pumping speed will reduce thereby affecting the rate of water circulation and causing the engine temperature to be higher than normal.

SPEED REDUCTION

Another sign of weak or loosed belts could be a slight reduction of the engine power output which is a result of its reduced speed.

As you can see in the above diagram if the engine has many belts connected to it and some or all of them have gone weak it will cause its dragging force to increase thereby reducing the overall engine speed which is clearly indicated by its work output or speedometer.

POSSIBLE BELT SLIPPING OFF THE PULLEY OR TEARING APART

Another problem a weak and loose belt could cause is to slip off or tear apart from the pulley if extra force is applied to try to force its speed, this usually occurs when an engine is operating at a very high speed with weak belts.

And incidents like that will lead to other serious faults to the main engine and other components.

  1. I love to share experiences with my fellow Drivers, operators & owners of motor vehicles and Industrial engines why they should checked & change their Engines Belts in a timely manner and avoid unexpected breakdown in the WRONG PLACES and TIME.
    IT`S LIKE HELP SAVE A LIFE.
