Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably appreciate the inherent qualities of this kind of engine. More torque, better fuel economy, easier maintenance are some of the qualities of owning a diesel-powered vehicle. Still, some motorists complain about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel motor can be fine-tuned to produce more energy without hurting fuel economy. Let’s take 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 cars run is via 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 across the country. Some passenger vehicles, mainly pickup trucks, are also diesel-powered, giving motorists an option to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to create combustion versus the air/fuel mixture needed by Petroleum powered cars. This attribute means that diesel engines do not need spark plugs and hence do not have to be tuned up.
• Diesel fuel has a higher 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 life-span 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 vehicle can deal with the challenge.
So, why aren’t more vehicles in Sydney diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so few producers have improved upon the innovation to produce an eco-friendly engine. Nevertheless, numerous 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. A lot of 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.
Thankfully, numerous aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Efficiency programmers, are assisting motorists in seeing a great spike in horsepower in addition to increases in torque. The beauty of some 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 cars presently on Australian highways is very little; however, with more recent, cleaner, and more powerful engines on the way, you may soon find yourself going with a diesel-powered vehicle too.

Diesel Engine Principles for Novices
Diesel engine principles are quite direct for the experienced mechanic but what about regular everyday individuals who have never put in the time to discover more about a diesel engine and how it works?
In this short article, we are going to explain in layman’s terms the basic 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 know is a petrol engine and a diesel engine are totally different. A Petrol engine is built much lighter than the much heavier developed diesel engine and works 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 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 area inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up 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 works on 4 strokes or 4 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 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 pushes 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 upward the valves close which traps the intake air in the cylinder which enables 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 a surge happens in the cylinder because of the mix of heat and atomized diesel fuel. This causes the piston to be forced downward which produces torque and the horsepower needed from a normal diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the previously sparked gases to escape to the atmosphere out the exhaust system.
As discussed before, each cylinder goes through this specific 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 discussed above. This series has been engineered to enable the diesel engine to run efficiently with no 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 advantage, so it is recommended that you discover more about diesel motors before you decide which one to select.
