Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably value the fundamental qualities of this kind of engine. More torque, much better fuel economy, easier maintenance are some of the attributes of owning a diesel-powered vehicle. Still, some motorists 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 damaging 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 significant role in powering buses and trucks throughout the nation. Some passenger cars, generally pickups, are also diesel-powered, providing motorists an option to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mix needed by Petroleum powered automobiles. This characteristic means that diesel engines do not need spark plugs and thus 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 similar petroleum-powered models.
• Diesel engines are less expensive to maintain as they have fewer parts vs. a petroleum engine. The lifespan 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, particularly when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered vehicle can handle the difficulty.
So, why aren’t more cars in Peakhurst Heights diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so not many producers have improved upon the innovation to produce an environmentally friendly engine. However, numerous upcoming engines may change all of that.
Insufficient power. Yes, a typical complaint, even with turbo-diesel, is that the engines are not powerful enough. Most chauffeurs 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, numerous aftermarket product designers are assisting motorists 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 harm fuel economy. In fact, some claim to assist improve it.
Yes, the variety of diesel-powered passenger vehicles currently on Australian highways is very little; however, with more recent, cleaner, and stronger engines on the way, you may soon find yourself selecting a diesel-powered vehicle too.

Diesel Engine Principles for Newbies
Diesel engine principles are pretty direct for the experienced mechanic but what about regular everyday people who have never taken the time to discover more about a diesel engine and how it works?
In this post, we are going to describe 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 constructed much lighter than the heavier developed 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 vehicle.
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 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 runs on four strokes or four cycles- both these terms mean the exact same. Here is how the four-stroke diesel engine runs.
1. Intake Stroke:
Intake valves in the cylinder head open allowing pressurized air to get in 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 providing the diesel engine an increase of air to keep up with a rapid 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 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 takes place a surge takes place in the cylinder because of the combination of heat and atomized diesel fuel. This triggers 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 sparked gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this exact series 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 mentioned above. This series has been crafted to enable the diesel engine to run smoothly without any imbalance.
There is much to find out about diesel engines and a ton of information online. If you have ever thought about purchasing an automobile with a diesel engine you have made a prudent decision! The extra cost will be to your benefit, so it is recommended that you discover more about diesel engines before you choose which one to select.
