It will also take longer for your windows to defrost as your airflow system will be blowing out cold air for longer before it gets warm if you have a diesel engine than a gas engine. This is because you have to wait for the glow plugs to get hot enough to ignite the diesel, so starting a diesel vehicle often requires a two-step ignition process.
The very latest modern diesels are much more technologically advanced, however, and my last Mercedes C-Class started just like a gas-powered version would with a single press of the start button. In general, diesel engines work and perform better in warm climates than they do in cold climates, although diesel powerplants tend to be tougher, more durable and more reliable than gas engines in most environments.
Diesel freezes quicker than gasoline as gasoline has a lower freezing point than diesel, and the paraffin in diesel fuel begins to thicken at 32 degrees Fahrenheit leaving the fuel looking cloudy. Glow plugs are heating devices used to assist in the starting of diesel engines. As it can be hard to start high-speed diesel engines in very cold weather due to the mass of the cylinder block and the cylinder head absorbing the heat of compression and preventing ignition, pre-chambered engines have for a long time use small glow plugs inside the pre-chambers.
More modern diesel engines are now direct-injected, and these engines have their glow plugs located in the combustion chamber itself. Many older diesel vehicles have a two-stage ignition system where the first part is initiating the glow plugs and the second part is where the pressurized fuel is injected into the cold cylinder and ignited by the glow plug. Modern diesels do not require glow plugs or any additional starting aid, but those older units that do operate using glow plugs can need as much as 20 seconds to elapse after the first turn of the ignition before the glow plug light on the dash goes out to signal that you can now fire up the engine.
As well as telling you where to go to get the very lowest prices on new and used vehicles, I also cover finance, insurance, parts, detailing and other stuff too. Diesel engines are an impressive show of engineering capability. They are regarded as some of the most reliable and durable mechanical creations.
So naturally, they are used by some of the largest and most innovative motorized vehicles in the world. But what makes a diesel engine so much better than its gasoline counterpart?
And how does a diesel engine have such a long performance life? But diesel engines can continuously run for an impressive 1,,,, miles before needing any major work. In fact, a well-maintained diesel engine can be on the road for 30 years or more.
The design of a diesel engine is gear-driven. Unlike other parts that can be broken or damaged, gears can be easily fixed and never lose timing. Most diesel vehicles may also make use of gear-driven water and oil pumps. This decreases the risk of parts and components failing. Vehicles that use diesel engines are generally built with heavy-duty components that can withstand the power of the vehicle, which means less wear and tear on every part of the engine. Properly maintained, most mechanics agree you can expect to keep a diesel vehicle on the road for a solid 30 years.
They do, however, require some special care. For example, you can't expect a diesel to sit all day in sub-zero temperatures and start easily. In an Edmonton winter, you'll likely need starting fluid to get the engine running.
Diesel engines generally last longer, but they can be costly to repair. For starters, diesels have an intricate and expensive fuel pump. In addition, any water inadvertently passing through a diesel's injectors or distribution pump will cause major damage, so the engine oil filters are also unique. These extra filters must be changed regularly, and they're not cheap. Fuel availability is also a consideration as not all service stations offer diesel, so you'll need to make sure you have a reasonably convenient supply.
Let's move on to the environmental impact. Which vehicle type is better? According to Dr.
