The myths of diesel

5 Myths about Having Diesel engines

Heavy trucks are mainly used for handling and hauling heavy weight which means they need heavy torque. These exceptionally high torques can easily be achieved by diesel engines. The reason most trucks use diesel instead of petrol engines is because diesel engines produce lower speeds but high torque.

There are certain myths that are persistently bandied onto the diesel engines regarding their durability, performance and versatility.  Given the increasing popularly of diesel engines in recent years let me address a few of these myths.

I. Diesel Price is higher than gasoline price. Diesel production is not more expensive that gasoline production. In the instance that diesel is more expensive than gasoline the difference can be attributed to taxation and pump owners. The availability also shapes the prices. Higher diesel demands shoot the prices up which accounts for the places where diesel cost more than gasoline at the pump.

II. Diesel is dirty. The thick black fumes emitted by diesel trucks is because of particulate matter from the car exhaust system as well as accumulated soot. Diesel Particulate Filter (DPF) can easily rectify this huge smoke production by cutting down the smoke fumes to a mere 5%. This works by having the fuel burn into the combustion engines producing heat that activates the DPF to burn out the accumulating soot.

III. Diesel Fuel Freezes in winter. Cold-starting, modern day engines technologies is a very simple and efficient inclusion in most trucks. When the temperature hits 5 degrees Celsius some diesel hydrocarbons turn gelatinous causing the fuel to jell. Vehicles with glow plugs can easily warm up and aerosolize the fuel and the car starts without any difficulty.

IV. Diesel Engines Are Sluggish. Because trucks are the most common users of diesel and because most of them drive slowly, it is often falsely concluded that diesel engines are therefore slow. The truth is most trucks always carry or tow heavy loads, that’s why they need the high torque.  Diesel engines are very efficient at the 65 miles per hour and below speeds which is where most driving happens anyway. You will find diesel engines are faster, more efficient with great acceleration and consumption.

V. Most Pumps Don’t Sell Diesel. Given the popularity of diesel engine cars, the neighbourhood pumps all have diesel. Anyone who has driven diesel trucks for long will tell you that there are a countable number of pumps that do not have diesel. You probably have the same number of pumps that have gasoline as those that have diesel. Point to note is that diesel engines have become popular owing to their fuel efficiency and lower carbon dioxide emissions relative to gasoline truck engines.
