Diesel Engines: What You Need To Know
If you own a diesel-powered car, you most likely value 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 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 tweaked to produce more energy without hurting 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 considerable role in powering buses and trucks across the nation. Some passenger vehicles, mainly pickup trucks, are likewise diesel-powered, offering motorists an option to petroleum.
Diesel engines have the following benefits over their petroleum counterparts:
• Diesel use air compression to create combustion versus the air/fuel mix needed by Petroleum powered automobiles. This quality means that diesel engines do not need spark plugs and hence do not have to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to fuel economy boosts 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 lifespan of a diesel engine is likewise 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 car can manage the challenge.
So, why aren’t more vehicles in Huntleys Cove diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines contaminate more, so very few manufacturers have improved upon the innovation to produce an eco-friendly engine. However, a number of upcoming engines might change all of that.
Inadequate power. Yes, a common complaint, even with turbo-diesel, is that the engines are not powerful enough. A lot of motorists 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.
Fortunately, 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 great spike in horsepower in addition to increases in torque. The beauty of some of these aftermarket parts is that they do not damage fuel economy. In fact, some claim to help improve it.
Yes, the number of diesel-powered passenger automobiles currently 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 car too.

Diesel Engine Principles for Beginners
Diesel engine principles are quite direct for the experienced mechanic but what about routine everyday people 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 explain in layman’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 understand is a petrol engine and a diesel engine are absolutely different. A Petrol engine is constructed much lighter than the much heavier built 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 developing power and torque [turning force] which drives your car.
A diesel engine uses high compression [intake air that is compressed/squished] into a very little space inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which sparks a very 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 same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open enabling 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 instant 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 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 happens a surge occurs 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 enabling the formerly 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 example, 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 series has been engineered to allow 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 thought about buying a car with a diesel engine you have made a prudent decision! The extra cost will be to your benefit, so it is recommended that you discover more about diesel motors before you choose which one to select.
