Diesel Engines: What You Need To Know
If you own a diesel-powered car, you probably appreciate the inherent qualities of this type of engine. More torque, better fuel economy, much easier maintenance are a few of the characteristics 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 tweaked to produce more energy without harming fuel economy. Let’s have a look at diesel motors and what you can do to eject 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 primary way most vehicles 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 throughout the country. Some passenger cars, mainly pickups, are likewise diesel-powered, offering drivers a choice to petroleum.
Diesel engines have the following advantages over their petroleum equivalents:
• Diesel use air compression to produce combustion versus the air/fuel mixture required by Petroleum powered cars. This quality means that diesel motor do not need spark plugs and hence do not need to be tuned up.
• Diesel fuel has a higher fuel density than petroleum resulting in fuel economy increases of 20-30% over comparable petroleum-powered designs.
• Diesel engines are less expensive to maintain as they have fewer parts vs. a petroleum engine. The life expectancy 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, especially when starting from a dead stop, but when climbing up hills or going over bridges, your diesel-powered car can deal with the challenge.
So, why aren’t more cars in Greenwich 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. Nevertheless, several 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. The majority of chauffeurs 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 developers are helping drivers eject more power from their diesel engines. Performance developers, are helping motorists in seeing a nice spike in horse power in addition to 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 assist improve it.
Yes, the number of diesel-powered passenger vehicles presently on Australian highways is very little; however, with newer, cleaner, and more powerful engines on the way, you may soon find yourself going with a diesel-powered car too.

Diesel Engine Principles for Beginners
Diesel engine principles are pretty easy for the experienced mechanic but what about routine everyday people who have never made the effort to find out more about a diesel engine and how it works?
In this article, we are going to explain in layperson’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 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 operates on an air/fuel mixture combined with a high energy spark that is timed to ignite the air/fuel mixture 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 an extremely small area inside each cylinder triggering extreme heat! This is called ‘Heat of Compression’ which sparks an extremely great 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 operates on four strokes or four cycles- both these terms mean the very same. Here is how the four-stroke diesel engine operates.
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 pushes air into the intake system offering the diesel engine an increase of air to keep up with a rapid 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 enables 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 triggers 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 allowing the formerly 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 enable the diesel engine to run smoothly without any imbalance.
There is much to find out about diesel engines and a ton of info online. If you have ever thought about purchasing a car with a diesel engine you have made a prudent decision! The additional cost will be to your benefit, so it is recommended that you find out more about diesel motors before you choose which one to choose.
