Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you probably appreciate the intrinsic qualities of this type of engine. More torque, better fuel economy, easier maintenance are some of the qualities of owning a diesel-powered automobile. Still, some 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 tweaked to produce more energy without hurting fuel economy. Let’s have 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 comes to driving. Besides hybrid or rotary engines, the primary way most vehicles run is via a petroleum-powered internal combustion engine. Nevertheless, 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 country. Some passenger cars, generally pickups, are also diesel-powered, giving drivers an alternative to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to create combustion versus the air/fuel mix needed by Petroleum powered cars and trucks. This quality means that diesel engines do not need spark plugs and therefore do not have to be tuned up.
• Diesel fuel has a higher fuel density than petroleum leading to fuel economy increases of 20-30% over equivalent petroleum-powered models.
• Diesel engines are more affordable to maintain as they have less 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, especially when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered automobile can manage the challenge.
So, why aren’t more cars in Pymble diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so not many manufacturers have improved upon the innovation to produce an environmentally friendly engine. Nevertheless, a number of upcoming engines may change all of that.
Not enough power. Yes, a common 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.
Fortunately, a number of aftermarket product designers are helping drivers squeeze out more power from their diesel engines. Efficiency developers, are assisting motorists in seeing a great spike in horsepower as well as increases in torque. The beauty of some of these aftermarket parts is that they do not harm 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 stronger engines on the way, you may soon find yourself selecting a diesel-powered automobile 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 made the effort to find out more about a diesel engine and how it works?
In this short article, we are going to describe in layman’s terms the basic principles of a diesel engine. Let’s begin, 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 totally different. A Petrol engine is built much lighter than the much heavier built diesel engine and works on an air/fuel mix combined with a high energy spark that is timed to fire up the air/fuel mix inside each engine cylinder at the exact time developing power and torque [turning force] which drives your automobile.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a really small space inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which ignites a really 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 utilizes ‘Heat of Compression’
The four-stroke principle
Every engine today works on 4 strokes or 4 cycles- both these terms mean the very same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open enabling pressurized air to enter each cylinder while the piston is traveling downward.the the pressurized air supply is made possible by the TURBOCHARGER which presses air into the intake system giving the diesel engine an increase of air to keep up with an instant injection of fuel
2. Compression Stroke:
When the piston starts to make its way back upward the valves close which traps the intake air in the cylinder which enables compression to happen, 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 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 enabling the formerly ignited gases to escape to the environment out the exhaust system.
As pointed out before, each cylinder goes through this exact sequence 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 pointed out above. This sequence has been engineered to permit the diesel engine to run smoothly with no imbalance.
There is much to discover diesel engines and a lots of information online. If you have ever thought about purchasing a car 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 motors before you decide which one to select.
