Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely value the intrinsic qualities of this type of engine. More torque, much better fuel economy, much easier maintenance are some of the attributes of owning a diesel-powered car. Still, some vehicle drivers complain about the engine’s weak power, particularly 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 harming 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 concerns driving. Besides hybrid or rotary engines, the primary way most vehicles run is by means of 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 throughout the nation. Some passenger vehicles, primarily pickups, are also diesel-powered, offering vehicle 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 vehicles. This attribute means that diesel motor do not need spark plugs and hence do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy increases of 20-30% over equivalent petroleum-powered designs.
• Diesel engines are cheaper to maintain as they have less parts vs. a petroleum engine. The lifespan of a diesel engine is also significantly 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, specifically when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered car can manage the difficulty.
So, why aren’t more vehicles in Hurlstone Park diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so not many manufacturers have improved upon the technology to produce an environmentally friendly engine. Nevertheless, numerous upcoming engines might change all of that.
Inadequate 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.
Fortunately, numerous aftermarket product developers are helping vehicle drivers squeeze out more power from their diesel engines. Efficiency developers, are assisting motorists in seeing a good 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 number of diesel-powered passenger vehicles currently on Australian highways is minimal; however, with more recent, cleaner, and more powerful engines on the way, you might soon find yourself opting for a diesel-powered car too.

Diesel Engine Principles for Beginners
Diesel engine principles are quite straightforward for the experienced mechanic but what about routine everyday people who have never taken the time to learn 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 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 totally different. A Petrol engine is constructed much lighter than the 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 precise time developing power and torque [turning force] which drives your car.
A diesel engine uses high compression [intake air that is compressed/squished] into an extremely small space inside each cylinder causing 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 same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open permitting 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 a rapid 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 permits 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 precise time.
3. Power Stroke:
After injection occurs an explosion takes place in the cylinder because of the mix of heat and atomized diesel fuel. This triggers the piston to be forced downward which produces torque and the horse power needed from a typical 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 mentioned before, each cylinder goes through this precise 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 crafted to enable the diesel engine to run efficiently with no imbalance.
There is much to find out about diesel engines and a ton of details online. If you have ever thought about 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 learn more about diesel motors before you decide which one to choose.
