It is acknowledged that diesel engine vehicles are fewer in number than petrol engines, Garage Friends. Diesel cars are known for their large power and strong pulling characteristics, making them capable of driving on many terrains. The strong engine pull also makes diesel cars reliable to carry more weight.
In the past, diesel engine cars were synonymous with trucks or large commercial vehicles. However, as technology develops, this engine designed by Rudolf Diesel has become more modern and more efficient. Likewise with its performance, which is increasingly responsive and comfortable for everyday use.
What are the advantages of diesel engine vehicles? Here’s the explanation:
1. More efficient and fuel efficient
One of the characteristics of diesel which is its advantage is efficiency and fuel economy. The way a diesel engine works is by using very high compression, causing the fuel to burn more completely in the combustion chamber. The effect, apart from better performance, is also fuel efficient.
2. Large torque at engine speed
Another advantage of diesel is the large torque characteristic obtained at low engine speeds. The effect is that the engine character becomes more responsive. When used in dense urban traffic, this character is useful for making stop & go acceleration easier. Meanwhile, if used for driving out of town, it makes the engine more responsive when driving on terrain with steep inclines.
3. Easy Maintenance
Unlike petrol engines, the way diesel engines work is simpler and does not require ignition components such as spark plugs, spark plug cables and coils. For this reason, diesel engine maintenance is relatively easier. However, some components still need attention, such as the diesel filter. The quality of diesel fuel is often poor in Indonesia, making the diesel filter often dirty and needs to be replaced more quickly. If left unchecked, it will cause damage to other engine components.
4. Environmentally Friendly Exhaust Gas Emissions
Because the combustion of a diesel engine is more complete compared to a petrol engine, the resulting exhaust emissions are also much lower. These advantages are what make diesel engines a favorite in various countries in Europe which are known for having strict emission regulations.
However, Garage Friends should not immediately decide to buy a diesel engine car. Because, this diesel engine also has disadvantages that you should know about. The following are the disadvantages of diesel engines that you must pay attention to:
1. Slower Acceleration
Referring to the shortcomings of cars with diesel engines, it is claimed that they have slower acceleration. So don’t be surprised if the engine speed below feels slow. However, when moving to top speed, press the gas pedal deeply. The new large torque makes the diesel engine more powerful and the driver can feel it.
This phenomenon actually has quite a positive impact on drivers, especially beginners. Because when you press the gas pedal, the engine will not immediately ‘gas’.
2. Greater Emissions
Furthermore, the disadvantage of diesel engine cars is that they produce greater emissions. When compared with petrol engine cars, of course the exhaust emissions produced by diesel engines are much greater. This is revealed through the appearance of exhaust smoke which often occurs in diesel cars.
Especially if the maintenance is not carried out properly. It is not uncommon for diesel car exhausts to emit huge amounts of black smoke.
3. Rougher engine sound
The weakness of diesel-powered cars is that engine vibration tends to be rougher than petrol-powered cars. In fact, vibrations and engine noise often enter the cabin. Of course, this can interfere with comfort when driving.
Especially when the car is used to travel long distances. If there is lack of maintenance, noise can certainly disturb the comfort of the driver and passengers.
4. The price is expensive
The financial factor is one of the reasons why many Indonesians do not choose diesel cars. Diesel engine vehicles are expensive because they are built with thick and sturdy walls. The reason is so that the car can withstand high pressure.
Diesel Engine Vehicle Maintenance
There are two main keys to maintaining a diesel engine car, namely oil and fuel. First, about the condition of the engine oil. The workload of a diesel engine is considered extreme because the high compression ratio and the presence of a turbo produce very high temperatures and pressure in the engine room. For this reason, diesel engines need the right oil according to recommendations.
Then, it is highly recommended to use the latest diesel engine fuel (BBM) of high quality. This is because the application of the common rail system sprays fuel into the combustion chamber with an extra high pressure injector that is controlled electronically. On the other hand, if the quality of diesel fuel is low, dirt can damage the very precise injectors.
Here are some tips that must be followed so that the diesel engine remains durable and works optimally:
· Use Appropriate Fuel
Diesel fuel with low sulfur content and high cetane content allows the engine to work optimally with minimal disruption. Meanwhile, high sulfur content will disrupt the fuel distribution system, reduce engine performance and reduce engine life. Adjust the fuel used with the recommendations in the vehicle manual.
· Check the Fuel Filter
Optimal diesel fuel filter performance ensures that dirt will not escape into the fuel injection system. There is a warning light on the car’s instrument panel that lights up when the diesel filter is dirty. Immediately clean or replace with a new diesel filter.
· Clean the Air Filter and Monitor Water Sedimentary
The component that must also be checked is the air filter which filters the air entered into the combustion chamber. Clean air can maintain engine performance and use fuel more efficiently. Apart from that, of course it reduces the appearance of scale on moving components.
The function of the water sedimenter is to capture the water content in the fuel lines so that it does not flow into the fuel system, so that it does not interfere with engine performance and protects against the risk of rust. Immediately drain the water sedimenter when the indicator light on the instrument panel lights up because the water is full.
· Warm up the machine before use
Basically, all vehicle engines need to be warmed up before use. However, unlike petrol engines, diesel engines require a longer period of time before they are ready to operate and travel. This is because diesel engines are not equipped with spark plugs, so the engine temperature must be truly optimal to burn the fuel.
· Never Leave the Fuel Tank Empty
Although rare, there is a possibility that you forget to refuel and the tank becomes empty. In cars with diesel engines, you need to keep the fuel tank filled to prevent condensation from occurring and causing moisture in the engine. It’s even better if you install ventilation on the machine to remove steam that can appear at any time.
· Mandatory engine oil change and regular servicing
Check the oil level via the dipstick to make sure it doesn’t decrease before it’s time to replace it. Change diesel engine oil regularly every six months. That way, the oil is always maintained in good condition and can carry out its task of protecting diesel engine components properly.
