Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely appreciate the intrinsic qualities of this type of engine. More torque, better fuel economy, simpler maintenance are some of the attributes of owning a diesel-powered car. Still, some drivers complain about the engine’s weak power, particularly when accelerating from a full stop. What you might not know is that a diesel engine can be modified to produce more energy without damaging fuel economy. Let’s have 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 comes to driving. Besides hybrid or rotary engines, the main way most cars run is via a petroleum-powered internal combustion engine. However, 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 nation. Some passenger vehicles, mainly pickups, are likewise diesel-powered, providing drivers an option to petroleum.
Diesel engines have the following benefits over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mix required by Petroleum powered cars and trucks. This quality means that diesel motor do not need spark plugs and thus do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy boosts of 20-30% over comparable 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 likewise substantially longer.
If it is torque you need, particularly 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 deal with the obstacle.
So, why aren’t more vehicles in Bronte diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines contaminate more, so few producers have improved upon the technology to produce an eco-friendly engine. However, numerous upcoming engines might change all of that.
Not enough power. Yes, a common complaint, even with turbo-diesel, is that the engines are not powerful enough. The majority 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.
Thankfully, numerous aftermarket product designers are assisting drivers squeeze out more power from their diesel engines. Efficiency developers, 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 do not damage fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger cars currently on Australian highways is very little; however, with newer, cleaner, and stronger engines on the way, you might soon find yourself going with a diesel-powered car too.

Diesel Engine Principles for Novices
Diesel engine principles are pretty straightforward 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 article, we are going to explain in layperson’s terms the basic principles of a diesel engine. Let’s start, shall we?
What’s the difference between the petrol engine and a diesel engine?
The first thing you should understand is a petrol engine and a diesel engine are totally different. A Petrol engine is constructed much lighter than the heavier developed diesel engine and runs on an air/fuel mix integrated with a high energy spark that is timed to fire up the air/fuel mix inside each engine cylinder at the accurate 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 space inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up 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 uses ‘Heat of Compression’
The four-stroke principle
Every engine today runs 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 pushes air into the intake system providing the diesel engine an increase of air to stay up to date 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 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 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 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 enabling the previously sparked gases to escape to the environment out the exhaust system.
As pointed out before, each cylinder goes through this precise 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 passes, following the 4 strokes pointed out above. This sequence has been crafted to enable the diesel engine to run efficiently with no imbalance.
There is much to discover diesel engines and a ton of details online. If you have ever thought about buying 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 find out more about diesel engines before you decide which one to choose.
