Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you probably appreciate the fundamental qualities of this type of engine. More torque, better fuel economy, much easier maintenance are some of the characteristics of owning a diesel-powered automobile. Still, some motorists complain about the engine’s weak power, particularly when accelerating from a full stop. What you may not know is that a diesel engine can be fine-tuned 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 pertains to driving. Besides hybrid or rotary engines, the main way most automobiles run is via 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 throughout the nation. Some passenger cars, mainly pickups, are also diesel-powered, offering motorists an alternative to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mix required by Petroleum powered automobiles. This characteristic means that diesel motor do not need spark plugs and therefore do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy increases of 20-30% over similar petroleum-powered models.
• Diesel engines are more affordable to maintain as they have fewer 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 engine 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 automobile can deal with the challenge.
So, why aren’t more cars in Pennant Hills diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines pollute more, so not many manufacturers have improved upon the technology to produce an eco-friendly engine. However, numerous upcoming engines may change all of that.
Insufficient power. Yes, a common problem, 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 two times as long to get up to full speed.
Thankfully, numerous aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Efficiency developers, are assisting motorists in seeing a good spike in horse power as well as increases in torque. The beauty of some of these aftermarket parts is that they don’t hurt fuel economy. In fact, some claim to assist improve it.
Yes, the number of diesel-powered passenger automobiles currently on Australian highways is very little; nevertheless, with more recent, cleaner, and stronger engines on the way, you may soon find yourself choosing a diesel-powered automobile too.

Diesel Engine Principles for Beginners
Diesel engine principles are pretty easy for the experienced mechanic but what about regular everyday individuals who have never put in the time to discover more about a diesel engine and how it works?
In this post, we are going to discuss in layperson’s terms the basic 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 know is a petrol engine and a diesel engine are absolutely different. A Petrol engine is built much lighter than the heavier developed diesel engine and works 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 creating power and torque [turning force] which drives your automobile.
A diesel engine uses high compression [intake air that is compressed/squished] into a very little space inside each cylinder causing severe heat! This is called ‘Heat of Compression’ which fires up a very 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 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 runs.
1. Intake Stroke:
Intake valves in the cylinder head open allowing pressurized air to enter each cylinder while the piston is traveling downward.the the pressurized air supply is enabled by the TURBOCHARGER which presses air into the intake system offering the diesel engine a boost of air to keep up 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 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 occurs 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 horse power required 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 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 allow the diesel engine to run efficiently without any imbalance.
There is much to discover diesel engines and a ton of info online. If you have ever considered purchasing a vehicle with a diesel engine you have made a prudent decision! The extra cost will be to your advantage, so it is recommended that you discover more about diesel motors before you decide which one to pick.
