Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably value the intrinsic qualities of this type of engine. More torque, much better fuel economy, much easier maintenance are a few of the characteristics of owning a diesel-powered vehicle. Still, some motorists complain about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel motor can be tweaked to produce more energy without harming fuel economy. Let’s take a look at diesel motors and what you can do to squeeze out more power.
Thanks to the work of one man, Rudolf Diesel, we have a choice when it pertains to driving. Besides hybrid or rotary engines, the main way most automobiles run is via a petroleum-powered internal combustion engine. However, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a substantial role in powering buses and trucks throughout the country. Some passenger cars, generally pickups, are likewise diesel-powered, offering motorists an option to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to develop combustion versus the air/fuel mix needed by Petroleum powered vehicles. This characteristic means that diesel motor do not need spark plugs and therefore do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy boosts of 20-30% over comparable petroleum-powered designs.
• Diesel engines are less expensive to maintain as they have less parts vs. a petroleum engine. The life expectancy of a diesel engine is likewise considerably longer.
If it is torque you need, particularly for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, especially when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered vehicle can deal with the difficulty.
So, why aren’t more cars in Crows Nest diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so very few makers have improved upon the innovation to produce an environmentally friendly engine. However, several upcoming engines may change all of that.
Not enough power. Yes, a common complaint, even with turbo-diesel, is that the engines are not powerful enough. Most drivers are accustomed to getting on the highway with a minimum amount of effort. With a diesel engine, it can take as much as twice as long to get up to full speed.
Thankfully, several aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Performance developers, are helping motorists in seeing a good spike in horsepower along with increases in torque. The beauty of a few of these aftermarket parts is that they do not damage fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger automobiles presently on Australian highways is minimal; however, with newer, cleaner, and stronger engines on the way, you may soon find yourself opting for a diesel-powered vehicle too.

Diesel Engine Principles for Beginners
Diesel engine principles are pretty direct for the experienced mechanic but what about routine everyday people who have never taken the time to find out more about a diesel engine and how it works?
In this article, we are going to discuss in layman’s terms the basic principles of a diesel engine. Let’s begin, shall we?
What’s the distinction between the petrol engine and a diesel engine?
The first thing you should understand is a petrol engine and a diesel engine are absolutely different. A Petrol engine is constructed much lighter than the much heavier constructed diesel engine and runs on an air/fuel mix combined with a high energy spark that is timed to ignite the air/fuel mix inside each engine cylinder at the accurate time developing power and torque [turning force] which drives your vehicle.
A diesel engine uses high compression [intake air that is compressed/squished] into an extremely small area inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which fires up an extremely fine high-pressure mist of diesel fuel that is injected into the cylinder at the exact time.
So you now understand that a gpetrol engine needs a high energy spark to run while a diesel uses ‘Heat of Compression’
The four-stroke principle
Every engine today runs on four strokes or four cycles- both these terms mean the very same. Here is how the four-stroke diesel engine runs.
1. Intake Stroke:
Intake valves in the cylinder head open allowing pressurized air to go into each cylinder while the piston is traveling downward.the the pressurized air supply is enabled by the TURBOCHARGER which presses air into the intake system offering the diesel engine an increase of air to keep up with an immediate injection of fuel
2. Compression Stroke:
When the piston begins to make its way back up the valves close which traps the intake air in the cylinder which enables compression to occur, the HEAT OF COMPRESSION is reached when the piston reaches the top of the cylinder, the diesel fuel is then injected into the cylinder at the accurate time.
3. Power Stroke:
After injection occurs a surge takes place in the cylinder because of the combination of heat and atomized diesel fuel. This triggers the piston to be forced downward which produces torque and the horsepower needed from a normal diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open allowing the previously sparked gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this exact series over and over in a set firing order. For example, a 6 cylinder diesel engine has a firing order of 1- 5- 3- 6- 2- 4 which is the order that each cylinder passes, following the 4 strokes mentioned above. This series has been engineered to enable the diesel engine to run smoothly with no imbalance.
There is much to learn about diesel engines and a lots of information online. If you have ever considered purchasing an automobile with a diesel engine you have made a prudent decision! The additional cost will be to your benefit, so it is recommended that you find out more about diesel motors before you decide which one to select.
