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, easier maintenance are some of the attributes of owning a diesel-powered car. Still, some motorists 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 tweaked to produce more energy without damaging fuel economy. Let’s have a look at diesel motors and what you can do to eject 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 considerable role in powering buses and trucks throughout the nation. Some passenger cars, mainly pickup trucks, are also diesel-powered, providing motorists an option to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mix required by Petroleum powered cars. This characteristic means that diesel motor 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 equivalent petroleum-powered designs.
• Diesel engines are cheaper to maintain as they have less parts vs. a petroleum engine. The life expectancy of a diesel engine is also substantially 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, particularly 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 Paddington diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines pollute more, so few makers have improved upon the innovation to produce an environmentally friendly engine. However, numerous upcoming engines might change all of that.
Inadequate power. Yes, a typical problem, even with turbo-diesel, is that the engines are not powerful enough. Most 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 designers are assisting motorists eject more power from their diesel engines. Performance developers, are assisting motorists in seeing a good spike in horsepower in addition to increases in torque. The beauty of some of these aftermarket parts is that they don’t damage fuel economy. In fact, some claim to assist improve it.
Yes, the variety of diesel-powered passenger vehicles presently on Australian highways is very little; however, with newer, cleaner, and more powerful engines on the way, you might soon find yourself opting for a diesel-powered car too.

Diesel Engine Principles for Newbies
Diesel engine principles are pretty simple 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 article, we are going to explain in layman’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 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 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 very little area inside each cylinder causing extreme heat! This is called ‘Heat of Compression’ which ignites a very 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 uses ‘Heat of Compression’
The four-stroke principle
Every engine today runs on 4 strokes or 4 cycles- both these terms mean the very 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 pushes 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 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 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 horsepower required from a typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open allowing the formerly fired up gases to escape to the environment out the exhaust system.
As discussed 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 discussed above. This sequence has been engineered to enable the diesel engine to run efficiently without any imbalance.
There is much to learn about diesel engines and a lots of details online. If you have ever considered purchasing a vehicle with a diesel engine you have made a prudent decision! The additional cost will be to your benefit, so it is recommended that you find out more about diesel motors before you decide which one to pick.
