Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely appreciate the fundamental qualities of this type of engine. More torque, better fuel economy, easier maintenance are a few of the attributes of owning a diesel-powered car. Still, some vehicle drivers grumble about the engine’s weak power, especially when accelerating from a full stop. What you may not know is that a diesel engine can be modified to produce more energy without hurting fuel economy. Let’s take a look at diesel engines 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 concerns driving. Besides hybrid or rotary engines, the primary way most vehicles 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 considerable role in powering buses and trucks throughout the country. Some passenger vehicles, primarily pickup trucks, are also diesel-powered, providing vehicle drivers an alternative to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mixture needed by Petroleum powered automobiles. This quality means that diesel engines do not need spark plugs and thus do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum leading to fuel economy boosts of 20-30% over comparable petroleum-powered designs.
• Diesel engines are more affordable to maintain as they have fewer parts vs. a petroleum engine. The life-span 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 engine has the advantage. It is slower, specifically when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered car can manage the difficulty.
So, why aren’t more vehicles in Watsons Bay diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines contaminate more, so few manufacturers have improved upon the technology to produce an environmentally friendly engine. However, several upcoming engines may change all of that.
Not enough power. Yes, a typical grievance, even with turbo-diesel, is that the engines are not powerful enough. Many drivers 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, several aftermarket product designers are helping vehicle drivers squeeze out more power from their diesel engines. Performance programmers, are assisting motorists in seeing a good spike in horsepower as well as increases in torque. The beauty of a few of these aftermarket parts is that they don’t harm fuel economy. In fact, some claim to assist improve it.
Yes, the number of diesel-powered passenger vehicles presently on Australian highways is minimal; however, with more recent, cleaner, and more powerful engines on the way, you may soon find yourself choosing a diesel-powered car too.

Diesel Engine Principles for Beginners
Diesel engine principles are pretty simple for the experienced mechanic but what about regular everyday people who have never taken the time to find out more about a diesel engine and how it works?
In this post, we are going to discuss in layperson’s terms the basic 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 understand 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 runs on an air/fuel mixture integrated with a high energy spark that is timed to ignite the air/fuel mixture inside each engine cylinder at the precise time producing power and torque [turning force] which drives your car.
A diesel engine uses high compression [intake air that is compressed/squished] into a very small area inside each cylinder triggering severe heat! This is called ‘Heat of Compression’ which ignites a very great 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 exact same. Here is how the four-stroke diesel engine operates.
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 pushes air into the intake system providing 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 upward the valves close which traps the intake air in the cylinder which permits compression to take place, 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 precise time.
3. Power Stroke:
After injection happens a surge happens in the cylinder because of the combination of heat and atomized diesel fuel. This causes 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 permitting the formerly fired up gases to escape to the environment out the exhaust system.
As discussed before, each cylinder goes through this exact sequence over and over in a set firing order. For instance, 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 discussed above. This sequence has been crafted to allow the diesel engine to run smoothly with no imbalance.
There is much to find out 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 benefit, so it is recommended that you find out more about diesel engines before you decide which one to choose.
