Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably value the inherent qualities of this kind of engine. More torque, much better fuel economy, easier maintenance are a few of the attributes of owning a diesel-powered car. Still, some motorists complain 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 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 pertains to driving. Besides hybrid or rotary engines, the main way most vehicles run is by means of a petroleum-powered internal combustion engine. Nevertheless, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a substantial role in powering buses and trucks throughout the country. Some passenger vehicles, mainly pickups, are also diesel-powered, offering motorists an alternative to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mixture needed by Petroleum powered automobiles. This quality means that diesel engines do not need spark plugs and hence do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to fuel economy increases of 20-30% over equivalent petroleum-powered designs.
• Diesel engines are less expensive 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, especially for pulling a boat, camper, or equipment, then a diesel engine has the advantage. It is slower, especially when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered car can handle the obstacle.
So, why aren’t more vehicles in Neutral Bay 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. Nevertheless, several upcoming engines may change all of that.
Not enough power. Yes, a common problem, even with turbo-diesel, is that the engines are not powerful enough. A lot 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 two times as long to get up to full speed.
Fortunately, several 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 a few of these aftermarket parts is that they do not hurt fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger vehicles presently on Australian highways is very little; however, with newer, cleaner, and stronger engines on the way, you may soon find yourself selecting a diesel-powered car too.

Diesel Engine Principles for Beginners
Diesel engine principles are quite easy for the experienced mechanic but what about routine everyday individuals who have never taken the time to find out more about a diesel engine and how it works?
In this short article, we are going to discuss in layman’s terms the standard 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 completely different. A Petrol engine is constructed 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 exact time producing power and torque [turning force] which drives your car.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a very little area inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which sparks a very fine 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 utilizes ‘Heat of Compression’
The four-stroke principle
Every engine today operates on four strokes or four 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 enabling pressurized air to go into 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 offering the diesel engine an increase of air to keep up with an instantaneous 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 exact 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 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 enabling the formerly sparked 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 instance, 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 discussed above. This sequence has been crafted to allow the diesel engine to run smoothly with no imbalance.
There is much to learn about diesel engines and a lots of information online. If you have ever considered purchasing 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 find out more about diesel motors before you choose which one to choose.
