Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably appreciate the fundamental qualities of this type of engine. More torque, much better fuel economy, much easier maintenance are a few of the characteristics of owning a diesel-powered car. Still, some motorists grumble 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 tweaked 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 comes to driving. Besides hybrid or rotary engines, the primary way most vehicles run is by means of 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 across 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 develop combustion versus the air/fuel mixture required 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 resulting in fuel economy boosts of 20-30% over equivalent petroleum-powered designs.
• Diesel engines are less expensive 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, 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 obstacle.
So, why aren’t more cars in Haberfield diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so not many producers have improved upon the technology to produce an eco-friendly engine. However, numerous upcoming engines might 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.
Luckily, numerous aftermarket product designers are helping motorists squeeze out more power from their diesel engines. Efficiency programmers, are assisting motorists in seeing a great spike in horse power along with increases in torque. The beauty of a few of these aftermarket parts is that they do not hurt fuel economy. In fact, some claim to assist improve it.
Yes, the variety 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 choosing a diesel-powered car too.

Diesel Engine Principles for Novices
Diesel engine principles are quite 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 article, we are going to discuss in layman’s terms the fundamental 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 operates on an air/fuel mixture combined with a high energy spark that is timed to ignite the air/fuel mixture inside each engine cylinder at the accurate time creating 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 space inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which sparks 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 operates on 4 strokes or 4 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 allowing 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 providing the diesel engine a boost of air to keep up with an instant 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 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 accurate time.
3. Power Stroke:
After injection happens an explosion happens 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 required 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 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 mentioned above. This sequence has been crafted to enable the diesel engine to run efficiently without any imbalance.
There is much to learn about diesel engines and a ton of details online. If you have ever considered buying 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 find out more about diesel engines before you decide which one to pick.
