Also referred to as a compression ignition engine, a diesel engine is an internal combustion engine that makes use of heat of compression in order to initiate ignition and then burn fuel. This type of an engine is quite different from a spark-ignition engine, which uses a spark plug in order to ignite a mixture of air and fuel.
One thing that is for sure is that a diesel engine has a higher thermal efficiency than any other standard internal/external combustion engine. This is mainly as a result of its high compression ratio.
Keep reading to find out how to make sure your diesel engine is the right size to do the job.
What versions are available for diesel engines?
Diesel engines are manufactured in two main variations: two stroke and four stroke versions. In the first case, these engines were mainly used as an efficient replacement for the stationary steam engines. Ever since the year 1910, these types of engines have been in widespread use across the world mainly in ships and submarines. Their use of heavy equipment, trucks and locomotives in general has since grown immensely.
Size groups for diesel engines
There are three main size groups for these types of engines today. These are:
- Small Engines
- Medium Engines
- Large Engines
The small size engines deliver less than 188 KW of power. There are therefore not suited for large commercial applications. Medium size power torque engines are a great choice for commercial applications today. However, they might not be great if consistent power and use is required of them. Nevertheless, you have the option of settling for the larger power torque engines that are mostly used in ships, submarines and even aircrafts. These are the largest engines on the planet and have the ability to power machines that need high energy levels to operate.
So, why does sizing matter?
When choosing power torque engines, size is a major consideration that you will have to make. Many people hold the perception that smaller engines can be used for standby power requirements since they do not have to run all the time. This myth is not only a myth as such but it can be quite detrimental as well to the industry you need to utilise the engines in. Unfortunately, getting the wrong engine size is a common mistake that is committed by thousands of buyers all over the world regularly.
Not only does a small size power torque engine involve the risks of damaging your assets but can also affect other appliances that are connected to it. It can go further to create hazardous situations and even limit productivity of the unit as a whole. If anything, when you are choosing a diesel engine, you need to appreciate the fact that more is always better than less.
How to choose the right size of a diesel engine
When you are buying a diesel engine and you are searching for the ideal size for the job you want to do with it, it is vital to deal with a certified mechanic or expert who knows what they are talking about. Someone who understands how these engines work will be in the best position to calculate the right details for you and give you all the guidelines you want. When they give you recommendations, you ought to abide by them since they understand such types of engines and have likely gone through extensive training to ensure that the engines they use are the best fit for the job. Most importantly, make sure you know your requirements and go for a diesel engine that does the job right.
