Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely appreciate the inherent qualities of this kind of engine. More torque, better fuel economy, much easier maintenance are some of the attributes of owning a diesel-powered car. Still, some drivers complain about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel motor can be tweaked to produce more energy without damaging fuel economy. Let’s take 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 concerns driving. Besides hybrid or rotary engines, the primary way most vehicles 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 significant role in powering buses and trucks throughout the nation. Some passenger cars, generally 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 develop combustion versus the air/fuel mix required by Petroleum powered vehicles. This characteristic means that diesel motor do not need spark plugs and thus do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum resulting in fuel economy boosts of 20-30% over equivalent petroleum-powered models.
• Diesel engines are more affordable to maintain as they have fewer 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 motor has the advantage. It is slower, especially when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered car can handle the challenge.
So, why aren’t more cars in Cheltenham diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so few makers have improved upon the technology to produce an environmentally friendly engine. However, several upcoming engines may change all of that.
Inadequate power. Yes, a common problem, even with turbo-diesel, is that the engines are not powerful enough. Most motorists 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, several aftermarket product designers are assisting drivers squeeze out more power from their diesel engines. Performance programmers, are assisting motorists in seeing a good spike in horse power along with increases in torque. The beauty of some of these aftermarket parts is that they do not harm fuel economy. In fact, some claim to assist improve it.
Yes, the number of diesel-powered passenger vehicles presently on Australian highways is very little; however, with newer, cleaner, and stronger engines on the way, you may soon find yourself going with a diesel-powered car too.

Diesel Engine Principles for Newbies
Diesel engine principles are quite direct for the experienced mechanic but what about routine everyday individuals who have never taken the time to learn more about a diesel engine and how it works?
In this post, we are going to discuss in layman’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 absolutely different. A Petrol engine is constructed much lighter than the heavier constructed 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 precise time producing power and torque [turning force] which drives your car.
A diesel engine utilizes high compression [intake air that is compressed/squished] into an extremely small area inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which fires up an extremely 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 works on four strokes or four 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 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 a boost of air to keep up with an instantaneous 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 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 a surge 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 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 permitting the formerly sparked gases to escape to the environment out the exhaust system.
As mentioned before, each cylinder goes through this precise 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 mentioned above. This series has been engineered to permit the diesel engine to run efficiently with no imbalance.
There is much to learn about diesel engines and a lots of information online. If you have ever considered buying an automobile 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 choose.
