Diesel Engines: What You Need To Know
If you own a diesel-powered automobile, you most likely appreciate the fundamental qualities of this type of engine. More torque, much better fuel economy, much easier maintenance are a few of the qualities 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 motor 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 concerns driving. Besides hybrid or rotary engines, the main way most vehicles run is by means of a petroleum-powered internal combustion engine. Nevertheless, 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 pickup trucks, are also diesel-powered, providing motorists a choice to petroleum.
Diesel engines have the following advantages over their petroleum counterparts:
• Diesel use air compression to develop combustion versus the air/fuel mixture needed by Petroleum powered cars and trucks. This attribute means that diesel engines do not need spark plugs and therefore do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum resulting in fuel economy increases 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 lifespan 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 automobile can deal with the difficulty.
So, why aren’t more cars in Prestons diesel-powered?
Some of the reasons include:
More stringent emissions control standards: Diesel engines contaminate more, so very few producers have improved upon the innovation to produce an eco-friendly engine. Nevertheless, numerous 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. The majority 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.
Luckily, numerous aftermarket product designers are assisting motorists squeeze out more power from their diesel engines. Performance developers, are helping motorists in seeing a great spike in horsepower along with 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 variety of diesel-powered passenger vehicles currently on Australian highways is minimal; nevertheless, with more recent, cleaner, and more powerful engines on the way, you may soon find yourself choosing a diesel-powered automobile too.

Diesel Engine Principles for Novices
Diesel engine principles are quite straightforward for the experienced mechanic but what about regular everyday people who have never made the effort to discover more about a diesel engine and how it works?
In this post, we are going to explain in layperson’s terms the basic 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 understand is a petrol engine and a diesel engine are totally different. A Petrol engine is constructed much lighter than the heavier built diesel engine and runs on an air/fuel mixture integrated with a high energy spark that is timed to fire up the air/fuel mixture inside each engine cylinder at the exact time creating power and torque [turning force] which drives your automobile.
A diesel engine uses high compression [intake air that is compressed/squished] into an extremely small space inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which sparks an extremely 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 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 permitting pressurized air to go into 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 providing 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 upward the valves close which traps the intake air in the cylinder which allows compression to happen, 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 happens an explosion happens 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 normal diesel engine.
4. Exhaust Stroke:
After the power stroke, the piston moves upward once again while the exhaust valves open permitting the previously ignited gases to escape to the environment out the exhaust system.
As pointed out before, each cylinder goes through this exact sequence 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 pointed out above. This sequence has been crafted to allow the diesel engine to run efficiently without any imbalance.
There is much to find out about diesel engines and a lots of info online. If you have ever thought about 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 discover more about diesel motors before you decide which one to choose.
