Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you probably value the inherent qualities of this type of engine. More torque, better fuel economy, much easier maintenance are a few of the characteristics of owning a diesel-powered automobile. Still, some motorists grumble about the engine’s weak power, particularly when accelerating from a full stop. What you might not know is that a diesel motor can be modified to produce more energy without harming 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 primary way most vehicles 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 significant role in powering buses and trucks throughout the country. Some passenger vehicles, mainly pickups, 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 produce combustion versus the air/fuel mixture required by Petroleum powered automobiles. This quality means that diesel motor do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum leading to fuel economy increases of 20-30% over similar petroleum-powered models.
• 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 significantly longer.
If it is torque you need, particularly for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, especially when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered automobile can deal with the challenge.
So, why aren’t more vehicles in Willoughby East 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 environmentally friendly engine. However, several upcoming engines might change all of that.
Inadequate power. Yes, a common problem, even with turbo-diesel, is that the engines are not powerful enough. Most drivers 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 assisting motorists squeeze out more power from their diesel engines. Efficiency developers, are helping motorists in seeing a good spike in horsepower in addition to increases in torque. The beauty of a few of these aftermarket parts is that they don’t harm fuel economy. In fact, some claim to help improve it.
Yes, the number of diesel-powered passenger vehicles presently on Australian highways is minimal; nevertheless, with more recent, cleaner, and stronger engines on the way, you might soon find yourself choosing a diesel-powered automobile too.

Diesel Engine Principles for Newbies
Diesel engine principles are quite direct for the experienced mechanic but what about routine everyday people who have never made the effort to find out 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 know is a petrol engine and a diesel engine are totally different. A Petrol engine is built much lighter than the heavier built 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 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 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 4 strokes or 4 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 permitting pressurized air to get in 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 offering the diesel engine an increase of air to stay up to date with an immediate 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 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 precise time.
3. Power Stroke:
After injection takes place an explosion takes place 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 horsepower required from a normal diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the previously ignited gases to escape to the atmosphere out the exhaust system.
As discussed before, each cylinder goes through this precise 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 goes through, following the 4 strokes discussed above. This sequence has been crafted to enable the diesel engine to run efficiently with no imbalance.
There is much to find out about diesel engines and a lots 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 advantage, so it is recommended that you find out more about diesel engines before you choose which one to pick.
