Diesel engines are one of the earliest kinds of internal combustion engines used in a wide range of vehicles. Known for their efficiency and durability, diesel engines have a significant position in the automobile industry. However, despite their widespread usage, several myths and misconceptions continue to surround these powerhouse machines.

For your convenience, here we have debunked some common myths about diesel engines.

Following is the list of diesel engine myths and misconceptions.  

Diesel engines are generally considered a greater contributor to pollution and greenhouse gases. This is mainly due to the visible clouds of black smoke from the exhaust. 

Modern diesel engines are designed with advanced exhaust after-treatment systems like Selective Catalytic Reduction (SCR) or Diesel Particulate Filters (DPF), which aid in reducing the carbon footprint of diesel engines.

Besides engine design, here are some more ways to reduce the carbon footprint of a car. 

Older diesel engines were indeed noisy, contrary to their petrol counterparts. However, technological advancements enable automobile manufacturers to come up with a quiet engine design.

Upgraded intake manifold covering, sound dampers and efficient fuel injection systems have contributed significantly to making modern diesel engines quiet.

Next on the list of common myths about diesel engines is their lifespan. It is a misconception that diesel engines have a shorter lifespan. On the contrary, with proper maintenance, diesel engines can run smoothly for around 805k km.

However, you must create a monthly car maintenance checklist to ensure timely maintenance of your diesel engine car. 

It is commonly believed that diesel engines produce less output, as they are generally used in heavy-duty vehicles. On the contrary, diesel engines are known for their low-end torque creating enough output needed for a heavy-duty vehicle. 

Contrary to popular belief, diesel engines are not expensive to maintain in comparison to petrol engines. Although the maintenance routine and requirements are slightly different from petrol engines, it doesn’t affect the budget. 

Routine maintenance including changing oil and air filters, timely oil change and fuel system maintenance is required. That said, You must keep a check on these common maintenance mistakes that shorten a car’s lifespan. 

Diesel engines offer better fuel economy in comparison to petrol engines. This is because diesel engines have a higher compression stroke which helps in creating more torque. Aside from that, the diesel also has a higher energy-producing capacity. That said, if your diesel engine is consuming more fuel, here are some fuel-efficient driving habits that can aid in reducing fuel consumption.

Modern diesel engines feature a block heater and battery warmer which makes them suitable for all kinds of weather. Furthermore, diesel engines are exempted from fixed air-to-fuel ratio, making them ideal for higher altitudes. 

Some of the most common problems associated with diesel engines are oil oxidation, hard starting and glow plug failure. 

Diesel is free from lead and has lower emission levels than that of petrol. 

The prices of diesel change every month. For April 2024, diesel cost AED 3.09/litre. To know the cost of other fuels, read through our blog on petrol prices in the UAE. 

These were all the myths about diesel engines. Diesel engines are reputed for their higher durability and efficiency. Moreover, the lower-end torque and easy maintenance also make it ideal for vehicles.
