Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you most likely value the inherent qualities of this kind of engine. More torque, better fuel economy, simpler maintenance are some of the qualities of owning a diesel-powered vehicle. 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 tweaked 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 comes to driving. Besides hybrid or rotary engines, the main 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 throughout the country. Some passenger cars, primarily pickups, are also diesel-powered, giving motorists a choice to petroleum.
Diesel engines have the following benefits over their petroleum equivalents:
• Diesel use air compression to develop combustion versus the air/fuel mixture required by Petroleum powered vehicles. This attribute means that diesel motor do not need spark plugs and thus 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 similar petroleum-powered designs.
• Diesel engines are more affordable to maintain as they have less parts vs. a petroleum engine. The life-span 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 hills or going over bridges, your diesel-powered vehicle can manage the difficulty.
So, why aren’t more cars in Wahroonga diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines pollute more, so very few makers have improved upon the innovation to produce an eco-friendly engine. Nevertheless, several upcoming engines may change all of that.
Not enough power. Yes, a typical grievance, even with turbo-diesel, is that the engines are not powerful enough. The majority of 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, several aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Performance programmers, are assisting motorists in seeing a nice spike in horse power along with increases in torque. The beauty of some of these aftermarket parts is that they don’t hurt fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger cars presently on Australian highways is minimal; however, with more recent, cleaner, and more powerful engines on the way, you may soon find yourself choosing a diesel-powered vehicle too.

Diesel Engine Principles for Novices
Diesel engine principles are quite straightforward for the experienced mechanic but what about regular everyday individuals who have never taken the time to discover more about a diesel engine and how it works?
In this short article, we are going to describe in layperson’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 know is a petrol engine and a diesel engine are totally different. A Petrol engine is built much lighter than the much heavier constructed diesel engine and operates on an air/fuel mixture integrated with a high energy spark that is timed to fire up the air/fuel mixture inside each engine cylinder at the precise time producing 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 space inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which ignites 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 operates 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 enter 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 a boost 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 allows compression to happen, 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 precise time.
3. Power Stroke:
After injection occurs a surge occurs 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 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 fired up gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this exact 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 mentioned above. This series has been crafted to allow the diesel engine to run efficiently without any imbalance.
There is much to learn about diesel engines and a lots of info online. If you have ever thought about purchasing a car with a diesel engine you have made a prudent decision! The additional cost will be to your benefit, so it is recommended that you discover more about diesel motors before you choose which one to choose.
