Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you most likely appreciate the inherent qualities of this kind of engine. More torque, much better fuel economy, easier maintenance are a few of the characteristics of owning a diesel-powered automobile. 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 hurting 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 concerns driving. Besides hybrid or rotary engines, the main way most cars 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 across the nation. Some passenger vehicles, mainly pickups, are also diesel-powered, giving motorists an alternative to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to produce combustion versus the air/fuel mix required by Petroleum powered vehicles. This attribute means that diesel motor do not need spark plugs and therefore do not need 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 models.
• Diesel engines are less expensive 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 automobile can deal with the obstacle.
So, why aren’t more vehicles in Normanhurst diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so few manufacturers have improved upon the technology to produce an eco-friendly engine. However, several upcoming engines may change all of that.
Not enough power. Yes, a typical complaint, even with turbo-diesel, is that the engines are not powerful enough. Many 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 developers are helping motorists squeeze out more power from their diesel engines. Performance developers, are helping motorists in seeing a nice spike in horsepower 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 number of diesel-powered passenger cars currently on Australian highways is very little; however, with newer, cleaner, and more powerful engines on the way, you may soon find yourself selecting a diesel-powered automobile too.

Diesel Engine Principles for Newbies
Diesel engine principles are pretty straightforward for the experienced mechanic but what about routine everyday people who have never taken the time to discover more about a diesel engine and how it works?
In this article, we are going to discuss in layperson’s terms the standard 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 much heavier constructed diesel engine and runs on an air/fuel mix integrated with a high energy spark that is timed to ignite the air/fuel mix inside each engine cylinder at the accurate time developing power and torque [turning force] which drives your automobile.
A diesel engine utilizes high compression [intake air that is compressed/squished] into a really little area inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which sparks a really great 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 runs on 4 strokes or 4 cycles- both these terms mean the same. Here is how the four-stroke diesel engine runs.
1. Intake Stroke:
Intake valves in the cylinder head open permitting 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 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 enables 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 happens a surge takes place 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 horsepower required from a typical diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the formerly sparked 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 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 discussed above. This sequence has been engineered to permit the diesel engine to run efficiently without any imbalance.
There is much to find out about diesel engines and a ton of info online. If you have ever thought about buying a vehicle 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 engines before you decide which one to select.
