Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you most likely appreciate the fundamental qualities of this kind of engine. More torque, much better fuel economy, simpler maintenance are a few of the qualities of owning a diesel-powered vehicle. Still, some drivers grumble 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 fine-tuned to produce more energy without hurting 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 concerns driving. Besides hybrid or rotary engines, the main way most vehicles run is through 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 across the nation. Some passenger vehicles, primarily pickup trucks, are also diesel-powered, offering drivers a choice to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mix required by Petroleum powered cars. This characteristic means that diesel engines do not need spark plugs and thus do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy increases of 20-30% over similar petroleum-powered models.
• Diesel engines are less expensive to maintain as they have less parts vs. a petroleum engine. The life expectancy of a diesel engine is also 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 hills or going over bridges, your diesel-powered vehicle can deal with the challenge.
So, why aren’t more vehicles in Northbridge diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so few manufacturers have improved upon the innovation to produce an environmentally friendly engine. Nevertheless, numerous upcoming engines might change all of that.
Inadequate power. Yes, a typical problem, 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 two times as long to get up to full speed.
Thankfully, numerous aftermarket product designers are helping drivers squeeze out more power from their diesel engines. Efficiency programmers, are helping motorists in seeing a good 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 help improve it.
Yes, the variety of diesel-powered passenger vehicles currently on Australian highways is very little; however, with newer, cleaner, and more powerful engines on the way, you might soon find yourself selecting a diesel-powered vehicle too.

Diesel Engine Principles for Newbies
Diesel engine principles are quite easy for the experienced mechanic but what about regular everyday people who have never put in the time to learn more about a diesel engine and how it works?
In this article, we are going to explain in layman’s terms the basic 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 much heavier developed diesel engine and works 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 exact time creating power and torque [turning force] which drives your vehicle.
A diesel engine uses high compression [intake air that is compressed/squished] into a really little area inside each cylinder triggering 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 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 works on four strokes or four cycles- both these terms mean the very same. Here is how the four-stroke diesel engine runs.
1. Intake Stroke:
Intake valves in the cylinder head open enabling pressurized air to get in 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 offering the diesel engine an increase of air to stay up to date 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 happens an explosion occurs 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 required from a typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open enabling the formerly ignited gases to escape to the atmosphere out the exhaust system.
As pointed out before, each cylinder goes through this precise series 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 pointed out above. This series has been engineered to enable the diesel engine to run efficiently with no imbalance.
There is much to discover diesel engines and a ton of info online. If you have ever thought about 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 learn more about diesel engines before you choose which one to select.
