Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably appreciate the intrinsic qualities of this type of engine. More torque, better fuel economy, simpler maintenance are some of the characteristics of owning a diesel-powered vehicle. Still, some vehicle drivers complain about the engine’s weak power, especially when accelerating from a full stop. What you might not know is that a diesel motor can be fine-tuned to produce more energy without hurting fuel economy. Let’s take a look at diesel motors and what you can do to eject more power.
Thanks to the work of one man, Rudolf Diesel, we have a choice when it comes to driving. Besides hybrid or rotary engines, the main way most vehicles run is by means of a petroleum-powered internal combustion engine. However, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a significant role in powering buses and trucks across the nation. Some passenger vehicles, primarily pickup trucks, are also diesel-powered, giving vehicle drivers an alternative to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to develop combustion versus the air/fuel mixture needed by Petroleum powered cars and trucks. This characteristic means that diesel motor do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to fuel economy boosts of 20-30% over equivalent petroleum-powered models.
• Diesel engines are cheaper to maintain as they have less parts vs. a petroleum engine. The life expectancy of a diesel engine is also considerably longer.
If it is torque you need, especially for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, particularly when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered vehicle can manage the difficulty.
So, why aren’t more vehicles in Naremburn diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so few producers have improved upon the technology to produce an environmentally friendly engine. However, a number of upcoming engines might change all of that.
Inadequate power. Yes, a common complaint, even with turbo-diesel, is that the engines are not powerful enough. Most motorists are accustomed to getting on the highway with a minimum amount of effort. With a diesel engine, it can take as much as two times as long to get up to full speed.
Thankfully, a number of aftermarket product developers are helping vehicle drivers eject more power from their diesel engines. Performance developers, are helping motorists in seeing a nice spike in horse power as well as increases in torque. The beauty of some of these aftermarket parts is that they don’t hurt fuel economy. In fact, some claim to assist improve it.
Yes, the variety of diesel-powered passenger vehicles presently on Australian highways is minimal; nevertheless, with more recent, cleaner, and more powerful engines on the way, you might soon find yourself opting for a diesel-powered vehicle too.

Diesel Engine Principles for Newbies
Diesel engine principles are pretty straightforward for the experienced mechanic but what about regular everyday people who have never put in the time to learn more about a diesel engine and how it works?
In this short article, we are going to discuss in layman’s terms the fundamental principles of a diesel engine. Let’s start, shall we?
What’s the difference between the petrol engine and a diesel engine?
The first thing you should know is a petrol engine and a diesel engine are absolutely different. A Petrol engine is built much lighter than the heavier built diesel engine and operates on an air/fuel mixture combined with a high energy spark that is timed to fire up the air/fuel mixture inside each engine cylinder at the exact time producing power and torque [turning force] which drives your vehicle.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a really little space inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up a really fine high-pressure mist of diesel fuel that is injected into the cylinder at the exact time.
So you now know that a gpetrol engine needs a high energy spark to run while a diesel utilizes ‘Heat of Compression’
The four-stroke principle
Every engine today operates on 4 strokes or 4 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 permitting pressurized air to enter 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 giving the diesel engine a boost of air to stay up to date with an instantaneous injection of fuel
2. Compression Stroke:
When the piston starts 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 exact time.
3. Power Stroke:
After injection occurs an explosion occurs in the cylinder because of the mix of heat and atomized diesel fuel. This causes the piston to be forced downward which produces torque and the horse power needed from a common diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the formerly sparked gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this specific 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 goes through, 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 details online. If you have ever thought about purchasing a vehicle with a diesel engine you have made a prudent decision! The extra cost will be to your advantage, so it is recommended that you learn more about diesel motors before you choose which one to select.
