Diesel Engines: What You Need To Know
If you own a diesel-powered vehicle, you probably appreciate the inherent qualities of this kind of engine. More torque, much better fuel economy, much easier maintenance are some of the qualities of owning a diesel-powered vehicle. 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 engine can be modified to produce more energy without damaging 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 pertains to driving. Besides hybrid or rotary engines, the primary way most automobiles run is by means of a petroleum-powered internal combustion engine. However, with Diesel’s 1892 patent of the engine that bears his name, diesel power has played a considerable role in powering buses and trucks across the country. Some passenger vehicles, primarily pickup trucks, are also diesel-powered, offering motorists an option to petroleum.
Diesel engines have the following benefits over their petroleum equivalents:
• Diesel use air compression to develop combustion versus the air/fuel mixture needed by Petroleum powered cars. This attribute means that diesel engines do not need spark plugs and therefore do not have to be tuned up.
• Diesel fuel has a higher fuel density than petroleum resulting in fuel economy increases of 20-30% over similar petroleum-powered designs.
• Diesel engines are more affordable to maintain as they have fewer parts vs. a petroleum engine. The lifespan of a diesel engine is also considerably 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 handle the challenge.
So, why aren’t more vehicles in Collaroy diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so very few manufacturers have improved upon the technology to produce an environmentally friendly engine. However, a number of 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. Many 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, a number of aftermarket product designers are helping motorists squeeze out more power from their diesel engines. Efficiency programmers, are assisting motorists in seeing a nice spike in horsepower as well as increases in torque. The beauty of some of these aftermarket parts is that they do not hurt fuel economy. In fact, some claim to help improve it.
Yes, the variety of diesel-powered passenger automobiles presently on Australian highways is very little; nevertheless, with newer, cleaner, and stronger engines on the way, you might soon find yourself going with a diesel-powered vehicle too.

Diesel Engine Principles for Newbies
Diesel engine principles are pretty direct for the experienced mechanic but what about regular everyday individuals who have never put in the time to learn more about a diesel engine and how it works?
In this short article, we are going to describe in layman’s terms the fundamental principles of a diesel engine. Let’s begin, shall we?
What’s the distinction between the petrol engine and a diesel engine?
The first thing you should know 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 runs on an air/fuel mixture integrated with a high energy spark that is timed to ignite the air/fuel mixture inside each engine cylinder at the exact 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 very little area inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which sparks a very great 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 uses ‘Heat of Compression’
The four-stroke principle
Every engine today runs on four strokes or four cycles- both these terms mean the exact same. Here is how the four-stroke diesel engine runs.
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 offering the diesel engine a boost of air to stay up to date with a rapid 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 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 occurs a surge happens 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 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 fired up gases to escape to the environment out the exhaust system.
As discussed before, each cylinder goes through this exact 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 discussed above. This series has been engineered to enable the diesel engine to run efficiently without any imbalance.
There is much to learn about diesel engines and a ton of info online. If you have ever considered 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 learn more about diesel engines before you choose which one to pick.
