Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably appreciate the intrinsic qualities of this type of engine. More torque, much better fuel economy, simpler maintenance are some of the attributes of owning a diesel-powered car. Still, some drivers complain about the engine’s weak power, especially when accelerating from a full stop. What you may not know is that a diesel motor can be fine-tuned to produce more energy without damaging 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 comes to driving. Besides hybrid or rotary engines, the main way most cars run is through a petroleum-powered internal combustion engine. Nevertheless, 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 drivers an option to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to create combustion versus the air/fuel mix needed by Petroleum powered vehicles. This quality means that diesel engines do not need spark plugs and thus do not need to be tuned up.
• Diesel fuel has a greater fuel density than petroleum leading to 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 likewise substantially longer.
If it is torque you need, especially for pulling a boat, camper, or equipment, then a diesel motor has the advantage. It is slower, particularly when starting from a dead stop, but when climbing hills or going over bridges, your diesel-powered car can handle the obstacle.
So, why aren’t more vehicles in Warrawee diesel-powered?
Some of the reasons include:
Stricter emissions control standards: Diesel engines contaminate more, so not many makers have improved upon the innovation to produce an environmentally friendly engine. Nevertheless, numerous upcoming engines may change all of that.
Not enough power. Yes, a typical grievance, even with turbo-diesel, is that the engines are not powerful enough. Many chauffeurs 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.
Luckily, numerous aftermarket product developers are helping drivers squeeze out more power from their diesel engines. Efficiency developers, are helping 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 don’t hurt fuel economy. In fact, some claim to help improve it.
Yes, the number of diesel-powered passenger cars presently on Australian highways is very little; nevertheless, with more recent, 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 pretty straightforward 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 short article, we are going to explain in layperson’s terms the standard 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 constructed diesel engine and works on an air/fuel mix combined with a high energy spark that is timed to ignite 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 severe 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 four strokes or four cycles- both these terms mean the exact same. Here is how the four-stroke diesel engine operates.
1. Intake Stroke:
Intake valves in the cylinder head open permitting pressurized air to enter 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 keep up with an instantaneous injection of fuel
2. Compression Stroke:
When the piston begins 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 takes place an explosion occurs in the cylinder because of the mix of heat and atomized diesel fuel. This triggers 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 permitting the previously ignited gases to escape to the atmosphere out the exhaust system.
As discussed before, each cylinder goes through this specific 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 discussed above. This sequence has been engineered to permit the diesel engine to run efficiently without any imbalance.
There is much to find out about diesel engines and a ton of information online. If you have ever considered purchasing a vehicle with a diesel engine you have made a prudent decision! The additional cost will be to your advantage, so it is recommended that you discover more about diesel motors before you choose which one to choose.
