Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely appreciate the fundamental qualities of this kind of engine. More torque, better fuel economy, easier maintenance are a few of the attributes of owning a diesel-powered car. 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 fine-tuned 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 pertains to driving. Besides hybrid or rotary engines, the main way most automobiles run is through a petroleum-powered internal combustion engine. However, 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 nation. Some passenger vehicles, mainly pickup trucks, are also diesel-powered, offering motorists an option to petroleum.
Diesel engines have the following benefits over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mix required by Petroleum powered cars. This attribute 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 resulting in fuel economy increases of 20-30% over similar petroleum-powered designs.
• Diesel engines are cheaper to maintain as they have less 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, specifically when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered car can handle the obstacle.
So, why aren’t more vehicles in Bondi diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so few producers have improved upon the technology to produce an environmentally friendly engine. However, a number of 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. 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 twice as long to get up to full speed.
Thankfully, a number of 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 horse power along with increases in torque. The beauty of a few 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 automobiles currently on Australian highways is minimal; nevertheless, with newer, cleaner, and more powerful engines on the way, you may soon find yourself selecting a diesel-powered car too.

Diesel Engine Principles for Novices
Diesel engine principles are pretty simple for the experienced mechanic but what about routine everyday individuals who have never taken the time to discover more about a diesel engine and how it works?
In this article, we are going to describe in layperson’s terms the standard principles of a diesel engine. Let’s start, 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 heavier constructed 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 creating power and torque [turning force] which drives your car.
A diesel engine uses high compression [intake air that is compressed/squished] into a really small space inside each cylinder causing extreme heat! This is called ‘Heat of Compression’ which sparks a really 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 uses ‘Heat of Compression’
The four-stroke principle
Every engine today runs on four strokes or four 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 allowing pressurized air to get in 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 offering the diesel engine a boost of air to keep up with an immediate 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 allows 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 exact time.
3. Power Stroke:
After injection occurs a surge occurs 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 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 previously ignited gases to escape to the atmosphere 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 engineered to allow the diesel engine to run efficiently without any imbalance.
There is much to find out 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 extra cost will be to your advantage, so it is recommended that you discover more about diesel engines before you choose which one to choose.
