Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably value the inherent qualities of this type of engine. More torque, better fuel economy, easier maintenance are a few of the qualities of owning a diesel-powered car. Still, some drivers grumble about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel engine can be tweaked to produce more energy without harming 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 comes to driving. Besides hybrid or rotary engines, the main way most automobiles run is through 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 across the country. Some passenger vehicles, mainly pickup trucks, are also diesel-powered, giving drivers a choice to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to produce combustion versus the air/fuel mix needed by Petroleum powered cars and trucks. This attribute means that diesel motor do not need spark plugs and therefore do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum leading to fuel economy increases of 20-30% over comparable petroleum-powered models.
• Diesel engines are cheaper to maintain as they have less parts vs. a petroleum engine. The lifespan of a diesel engine is also considerably longer.
If it is torque you need, particularly 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 up hills or going over bridges, your diesel-powered car can deal with the difficulty.
So, why aren’t more vehicles in Hornsby Heights diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines pollute 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 common grievance, even with turbo-diesel, is that the engines are not powerful enough. The majority of motorists 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.
Luckily, several aftermarket product designers are assisting drivers squeeze out more power from their diesel engines. Efficiency developers, are helping motorists in seeing a good spike in horse power 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 number of diesel-powered passenger automobiles presently on Australian highways is minimal; nevertheless, with newer, cleaner, and stronger engines on the way, you may soon find yourself choosing a diesel-powered car too.

Diesel Engine Principles for Newbies
Diesel engine principles are quite easy for the experienced mechanic but what about regular everyday people who have never taken the time to learn more about a diesel engine and how it works?
In this post, we are going to discuss in layperson’s terms the fundamental 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 totally different. A Petrol engine is constructed much lighter than the heavier constructed diesel engine and operates on an air/fuel mix integrated with a high energy spark that is timed to fire up the air/fuel mix inside each engine cylinder at the exact 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 really little area inside each cylinder triggering severe heat! This is called ‘Heat of Compression’ which fires up a really 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 operates on four strokes or four 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 allowing 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 an increase of air to keep up 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 allows 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 a surge occurs 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 horse power 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 ignited gases to escape to the atmosphere out the exhaust system.
As mentioned before, each cylinder goes through this specific 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 passes, following the 4 strokes mentioned above. This sequence has been crafted to permit the diesel engine to run efficiently without any imbalance.
There is much to learn more about diesel engines and a ton of information online. If you have ever considered buying an automobile with a diesel engine you have made a prudent decision! The additional cost will be to your advantage, so it is recommended that you learn more about diesel engines before you decide which one to select.
