Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you most likely appreciate the inherent qualities of this type of engine. More torque, better fuel economy, simpler maintenance are a few of the characteristics 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 might not know is that a diesel motor can be tweaked to produce more energy without harming fuel economy. Let’s have 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 automobiles 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 significant role in powering buses and trucks across the country. Some passenger vehicles, primarily pickups, are likewise diesel-powered, giving motorists an option to petroleum.
Diesel engines have the following benefits over their petroleum equivalents:
• Diesel use air compression to produce combustion versus the air/fuel mixture needed by Petroleum powered cars. This characteristic means that diesel engines do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to fuel economy boosts of 20-30% over comparable petroleum-powered models.
• Diesel engines are cheaper to maintain as they have fewer parts vs. a petroleum engine. The life-span of a diesel engine is likewise substantially longer.
If it is torque you need, especially for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, particularly when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered vehicle can manage the obstacle.
So, why aren’t more vehicles in Rushcutters Bay diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so very few manufacturers have improved upon the innovation to produce an environmentally friendly engine. Nevertheless, numerous upcoming engines might change all of that.
Not enough power. Yes, a typical complaint, even with turbo-diesel, is that the engines are not powerful enough. A lot of 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.
Luckily, numerous aftermarket product developers are assisting motorists squeeze out more power from their diesel engines. Performance programmers, are assisting motorists in seeing a nice 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 automobiles presently on Australian highways is very little; nevertheless, with more recent, cleaner, and more powerful engines on the way, you might soon find yourself going with a diesel-powered vehicle too.

Diesel Engine Principles for Novices
Diesel engine principles are quite simple for the experienced mechanic but what about regular everyday people who have never made the effort to learn more about a diesel engine and how it works?
In this post, 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 understand is a petrol engine and a diesel engine are absolutely different. A Petrol engine is built much lighter than the heavier built diesel engine and works on an air/fuel mixture combined with a high energy spark that is timed to ignite 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 uses high compression [intake air that is compressed/squished] into a really small space inside each cylinder triggering 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 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 4 strokes or 4 cycles- both these terms mean the exact same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open allowing 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 giving 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 up the valves close which traps the intake air in the cylinder which enables 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 occurs an explosion occurs in the cylinder because of the combination of heat and atomized diesel fuel. This triggers the piston to be forced downward which produces torque and the horsepower needed from a common diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open allowing the previously ignited gases to escape to the environment out the exhaust system.
As discussed before, each cylinder goes through this specific 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 passes, following the 4 strokes discussed above. This series has been engineered to permit the diesel engine to run smoothly with no imbalance.
There is much to learn more about diesel engines and a ton of info online. If you have ever thought about purchasing 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 learn more about diesel motors before you decide which one to select.
