Although modern Diesel fuel injection systems have less moving parts than traditional mechanical systems they are more prone to damage due to the much smaller manufacturing tolerances.
Since Diesel fuel injection systems were first invented and used to control engine operation, water in the Diesel fuel has been the biggest contributor to the failure of such systems. Repairs are generally expensive due to the hi-tech nature of components and the amount of parts that can be affected by the contamination.
When cars are brought in for repairs, the type of replacement parts you get can depend on the service department you visit. Local dealerships use Original Equipment Manufacturer (OEM) parts, whilst you may get a choice between OEM and aftermarket parts from independent shops. OEM parts are built by the original car manufacturers, meaning they are generally the same part as that found in your vehicle. Aftermarket products, on the other hand, are ones generally produced by a company other than the original manufacturer. Typically, aftermarket is cheaper than OEM.
Diesel fuel has been the main choice of transportation and industry transport services, as well as regular consumers for decades. This is due to fact diesel engines last longer than spark-ignition engines in demanding applications and the diesel fuel offers a greater power density than other fuels, therefore packing more power per volume. The farming and construction industries benefit greatly from the efficiency and high power. Refined from crude oil, diesel fuels tend to produce many harmful emissions when burned. The cost for more power has been harmful pollutants to the environment and as such, Australians had taken more interest in alternative fuels in recent times. Among the most popular has been biodiesel.
Diesel fuel is the number one means of transportation across Australia. From trains, agricultural equipment, to trucks, diesel fuel is used for long distance journeys. Although consumers may find diesel to be relatively expensive, it provides its regular users with a range of benefits. It also has environmental benefits that makes it superior to petrol and gas used in everyday vehicles.
Diesel cars offer better mileage
Although you may be paying a couple extra dollars to fuel your tank, you will gain extra mileage compared to gas and petrol powered vehicles as diesel fuel produces and provides motorist more kilometres per litre than petrol or gas. Diesel powered vehicles can provide 25 – 30 % better fuel economy compared to petrol and gas which translates to an overall saving.
Diesel is an efficient and dense fuel
The compression of air to fuel ratio of a diesel engine produces fewer emissions, the lowest emissions of any oil based fluids. Vehicles run on gas have an emission rate that is 10 times greater than a modern diesel engine, meaning there are more harmful chemical products releasing pollutants into our air. Diesel power also releases minimal amounts of carbon monoxide, making it safer than both petrol and gas.
Diesel vehicles utilise more usable energy compared to other fuelled vehicles. They can generate 30% better fuel economy. While eliminating all emissions and pollutants would require the removal of all fuelled vehicles, diesel powered engines are essential to transportation and business purposes and are still required on our roads.
While you may say all fuel consumption is bad for the environment full stop, we are now in a society where transportation is a critical part of life. By changing over to diesel fuelled cars we have the opportunity to decrease the amount of emissions and carbon dioxide released into the atmosphere which helps to reduce the impact of vehicle emissions on the environment.
How much has the diesel industry changed within Australia? Have prices continued to rise or have they fallen? Are their more consumers now using diesel powered vehicles or has the industry started to decline?Over the past few years, diesel powered vehicles have become extremely popular in Australia with registered diesel vehicles accounting for 19.7% of all cars compared to to 13.8% in 2010. Also, the number of registered diesel vehicles increased by more than 60% between 2007 to 2012.
A key reason why diesel vehicles have become popular amongst the Australian public is due to the cost effectiveness of diesel power. It has become apparent amongst Australian consumers that diesel engines offer great fuel economy savings compared to petrol and gas, as savings have been seen to reach from 5-20%.
To gain a greater understanding of how the industry has changed over the past 10 years, here are some key facts about the diesel industry:
- Previously Diesel engines were designed to empower, heavy equipment and machinery, however this has translated into everyday work vehicles and standard passenger vehicles due to its cost benefits as well as vastly improved driveability and performance.
- Diesel fuel prices are now competing with regular unleaded prices.
- Out of the 18 million registered vehicles in Australia, 20.9% are now diesel vehicles.
- Due to innovations in research and development of diesel technology it is now possible to drastically reduce noise and emissions that were associated with early diesel engines.
- Australia has the fifth lowest diesel prices, amongst the OECD group.
- In Victoria diesel prices have decreased from $1.53 per litre (2014) to $1.16 per litre (end of 2016)
With this in mind having a diesel vehicle provides some great added value and features that is appealing to a large majority of the Australian public. Not only are their great savings for motorists but the relatively higher torque of a diesel powered car improves the overall driving experience.
When it comes to most diesel vehicles, the recommended service period is every 5,000 km or 6 months, whichever comes first. However, this service interval can differ quite significantly depending on the make and model of your car, as well as how much you drive on a regular basis. More of a city driver? Driving short distances on a regular basis can cause the oil in diesel cars to accumulate gunk or other contaminants. This means you may need more frequent oil changes than your highway and long journey driving counterparts. It can be tricky to determine when to bring your car in for servicing. So to make that thought process a little simpler; here are 5 key signs that your diesel car needs to be serviced.
