We live in an era where marine fuel prices are constantly increasing because of the soaring demand and weakening supply. This is why it is important you think carefully about which fuel to use so you can benefit from it in terms of cost and provision. Fortunately, the solution is not too far away.

We owe it to Rudolf Diesel, the inventor of diesel engines that has proven itself to be an extremely efficient machine. You can save on fuel without compromising the quality of service it can provide to your vehicle.

The price of diesel fuel is comparatively higher than that of the gasoline but has more energy density. This means that more energy can be sourced from diesel fuel compared to the same amount of gasoline. Ultimately, this enables heavy-duty equipment and transportation to experience efficiency at its finest.

Moreover, diesel is oilier and heavier with a boiling point that is higher than water. All these make the fuel super-efficient and cost-effective.

How Diesel Engines Work?

Identifying how a diesel engine works is all in its type of ignition. Spark ignition is what enables gasoline engines to operate while compression-ignition is what powers up diesel engines. In compression-ignition, heat is formed by drawing air to the engine and then subjecting it to a high level of compression.

As a result, there is an extremely high temperature in the engine. In fact, it is far higher than what is produced with gasoline engines. After that, diesel is then released to the engine and is ignited to mix with the air. Both the air and the fuel are then infused into the engine. This combination is vital so there is a limit to the compression of fuel to provide better efficiency.

Additionally, diesel engines can either come in two-cycle or four-cycle. The type of engine you choose will be based on how your machine will operate. There are also two variants to choose from; air-cooled engines and liquid-cooled engines. Note that it is suggested to use liquid-cooled engines as they are quieter and can even out the temperature.

Benefits of Using a Diesel Engine

We cannot stress how much of a better performer diesel is compared to gasoline engines. Here are a few reasons why:
