Diesel vs Gas Engines


Whether you're thinking about buying a diesel car or truck or becoming a diesel mechanic or simply would like to compare a diesel powered vehicle to a more conventional unleaded gasoline powered vehicle, there are a few things you need to bear in mind and understand. Each type of engine has its own advantages and drawbacks, so knowing what you need and how you need it for your personalized lifestyle is really important.

Today's diesel engines are certainly not what they have been 10 or even five years back. Gone are the days of pungent exhaust and unacceptably obnoxious engine sound. Diesel engines have become much cleaner, have more power and are considerably more dependable. These are some of the reasons that we are seeing more and more ordinary automobiles with diesel engines rather than the traditional gasoline engine.

Let's take a look at various differences between these two engine types.

Are the Engines of Diesel Trucks and Cars Better?

Theoretically, a diesel truck engine is quite similar to the engine of a truck powered by gas. They are both internal combustion engines that are designed to transform one type of energy to another type of energy. This energy then results in linear motion, which then causes forward motion to take place. The major difference is how the combustion takes place. A gas truck engine has fuel combustion come about thanks to sparks from spark plugs. A diesel truck engine has the fuel combustion take place from the heat of the pressurized air within the engine.

Safety of the Engine

As any diesel mechanic will tell you, although you can flame diesel fuel in the open air using merely a wick, it is significantly less explosive than gas and does not develop a flammable vapor. That means a diesel engine won't ever vapor lock. Moreover, a diesel mechanic will tell you that the engines in diesel trucks will be more efficient because of their fuel efficiency, which is practically constant as compared to the sporadic nature of a gasoline engine which often can use more fuel to get less power.

Engine Performance

As any diesel mechanic will explain, what makes a car so appealing is its ability to accelerate swiftly. For that reason, we need to evaluate the performance difference between both engine types. Because engines in diesel trucks and cars are focused on torque as opposed to horsepower, they'll run more efficiently but accelerate fairly slowly in comparison. For many automobile owners, that lack of acceleration is unsatisfactory. For motorists who are looking to use their car or truck for pulling heavy loads such as campers or boats, a diesel engine makes more sense.

Efficiency of the Engine

When you compare a diesel engine to a gasoline engine, we cannot overlook the efficiency between both engines. If you are looking for an engine that's going to be used long-term, then a diesel engine is going to be best for your needs because you will save money over the lifespan of the engine. With 20 - 30% less fuel consumption, the savings really can add up. Diesel engines also have a longer lifespan than their gasoline counterparts. A typical diesel engine lasts around 350,000 miles before needing an overhaul, the gasoline counterpart is good for about 120,000 miles. Should you be looking for short term benefits, however, then a gasoline engine will likely be for you since it will take a few years for a gasoline engine to be less cost effective overall than a diesel engine.

Ultimately the environmental advantage of using a diesel engine is what shifts the debate in favor of using it primarily. The engines of diesel trucks and automobiles produce only a minimal quantity of carbon monoxide, so minimal, actually, that they can be used underground. Less carbon monoxide impact on our atmosphere means a healthier planet, and that's something we should all be striving toward.

6 Simple Car Maintenance Tips That Will Help Your Car Last Longer

Cars are not designed to run indefinitely without periodic car maintenance. If you wait until problems occur, you'll probably end up damaging your car and paying a lot more than if you take care of your car on a regular basis. By doing these simple maintenance tasks, you can expect to get years of service out of your car.
1. Change the oil according to the manufacturer's recommended car maintenance schedule. For most vehicles, this is every 3,750 miles or every three months, whichever comes first. Changing the oil ensures that your engine oil is clean and at the right levels, which helps the engine keep running smoothly.
2. Check the radiator to ensure it is full and have a professional check the level of anti-freeze in your cooling system. If it overheats, this can cause significant damage that you could have avoided with some basic cooling system maintenance.
3. Inspect your car on a regular basis, and take the time to learn what to look for. The gauges can clue you in that there's a problem your mechanic should look at. Repairing a chipped window before it turns into a huge crack is a lot less expensive than replacing the entire windshield and a lot less hassle as well.
4. Go to the same mechanic for all of your work, even if it's the most basic things. By going to a single mechanic, he'll notice things you may not about your car and can give you car maintenance advice that a mechanic seeing it for the first time may miss.
5. Clean your car, inside and out, on a regular basis. Allowing dirt and grime to sit on your vehicle can damage it, causing the upholstery to wear out faster or the paint to start chipping. If possible, park your car in a garage or under a carport to keep it dry and help prevent rust.
6. Check your tire pressure with a pressure gauge and use a pump to fill them to the correct levels. This will help them to wear more evenly, and it also helps with increasing your gas mileage. When the weather changes is an important time to check the air pressure since temperature does affect air pressure.
Although you have to pay for car maintenance, these small costs are much easier on your budget than the big ones you'll have to pay if you neglect your car. Replacing major systems is expensive, as is getting an entirely new car if yours breaks down beyond reasonable repair sooner than it would have if you had taken care of it.

Signs That Your Car Needs A Tune-Up

Hard Starting: This is the most common form of car trouble. It's usually due to some unperformed maintenance. If the starter cranks the engine, the electrical system is probably okay. The culprit could be a starting sensor (on fuel injected models) or the choke mechanism (on engines with carburetors). Frequently, starting failure can be traced to an electronic component or a computer controlling the ignition system.
Knocking: The noise generally is heard when the engine is under load, such as when accelerating or climbing a hill. While it often may be caused by a thankful of interior gas, ignition knock frequently is a sign your engine needs attention. It also can be caused by a buildup of carbon inside the engine. Lake-model cars are equipped with a knock sensor which 'hears' the sound and makes corrective adjustments. But it cannot compensate for a severe malfunction, a condition that can affect engine performance and even damage the engine.
Stalling: This can be caused by incorrect speed adjustments, a malfunctioning sensor or switch, dirty fuel-system parts, worn spark plugs, or other engine deficiencies. Does it stall when hot? Cold? With air conditioning on? To make diagnosis easier, make note of when it happens and advise your technician.
Power Loss: How long since the fuel filter was changed? A dirty filter is a common cause of power loss. As noted under "poor gas mileage", there can be many causes of this condition, most of which can be located with a diagnostic procedure.
Poor Gas Mileage: By keeping a regular check of gas mileage (miles driven divided by gallons used); you can tell if your engine is losing efficiency. Increased gas consumption may be accompanied by other symptoms listed in this section. Note that poor gas mileage also may be due to: under inflated tires, engine running too cold, transmission malfunction, dragging brakes, misaligned wheels.
Dieseling: This also is known as "after-run". The engine keeps chugging and coughing for several seconds after the ignition is shut off. Causes can range from inferior gas to excessive idle speed. Carbon in the combustion chamber also may cause dieseling.
Exhaust Odor: The smell of rotten eggs comes from the catalytic converter, part of your car's emissions-control system. The odor can be due to an engine problem or it can be a sign that your car's catalytic converter is malfunctioning.
Rough Running: A malfunction in either the fuel or ignition system can cause an engine to run rough. It also can be due to an internal engine condition, such as a bad valve or piston. Does it occur when idling? When accelerating? At all speeds? Your best bet: have a qualified technician perform diagnostic and tune-up services as needed.

Springtime! Time For A Tune-up!


Hang the snow shovel in the back corner, put the ice scraper on the shelf. Check out the daffodils and get ready for Spring. Old man winter has buried his head for this season. It is time for convertibles, picnics, and the beach.
Before you go too far down that Spring road, remember to get your car ready for Spring as well. You do not want to find yourself along the road with the hood up waiting for a tow.
Go to your nearest auto shop and get a spring preventative maintenance review.
Gas prices are going to continue to go up so anything we can do to keep the auto in top working order will save money in the long run. Check and replace the air filter. A dirty air filter will cause a decrease in mileage and is an easy item to forget.
Replace the oil and filter. Check the fuel injectors and fuel filter. Check all the hoses and belts. If any wear replace now rather than waiting until they break down.
Top all fluids. Check cooling system fluid and replace if necessary or add if low. Check the battery. Are the terminals making good contact?
How are the tires? Notice any unusual wear. Are the tires properly inflated? Did you use a special winter tire. If so time to change back.
What about the outside of the car. Check for any dings that should be repaired. Give your vehicle a thorough cleaning inside and out. Clean the mats of all the road salt and vacuum the seats of all the accumulated debris.
Give your car some special care with a car wax or a car sealant to recover the showroom luster lost from the winter months.
With a little attention now, your car will be ready for the good times.

Getting a Tune-Up: An Absolute Must in Auto Repair

Over time, our beloved vehicles take a tremendous amount of wear and tear. They are asked to do so many things: pick up the kids on time, get us to and from the grocery store, and even take us on a cross country vacation. Auto repair is something that is inevitable because of all the trust that is put into a car. Getting regular tune-ups helps to show a car, and an auto mechanic, that not only is a car trusted, but it's cared for. When getting a tune-up there is a process that most auto mechanics follow, checking for certain things that tend to wear out or break down on a car easily.
One of the first things than any auto mechanic will check during a tune-up is the spark plugs and wire connections. A loose or burnt up spark plug is one of the most common reasons for electrical malfunction, and, coincidentally, it is one of the easiest to fix. Loose wire connections are also relatively easy to fix. During a tune-up the connections of wires are checked to make sure each wire fits in securely, minimizing the probability of electrical problems within the vehicle.
Air filters are key in any internal combustion engine. Without oxygen, the fuels are not able to burn and provide the large spark that is needed to start the car. However, regular old air will not do. The air needs to be cleaned before it enters the engine, which is where the air filter comes in. The filter is essential in providing the necessary clean air to the engine. When an air filter becomes dirty (which is a normal side-effect), extra fuel is needed to provide the "spark" and run the vehicle. This can cause added strain on the engine and on someone's purse.
Replacing the carburetor is the fuel injector. Fuel injectors essentially are valves that allow fuel to pass through them at the right speed to help move the car. If a fuel injector is broken, then there can be a delay between when the gas pedal is pushed and when the car actually moves. This can be disastrous if someone is trying to get from a stop to go position, especially if they are trying to go across a busy highway. Because of this it is necessary to always seek auto repair if there is a delay between the gas pedal and the movement of the car.
Auto repair is something that is unable to be avoided whenever someone owns a vehicle. And, getting a tune-up is essential to making sure a car is able to stay in good working performance. They can help spot small problems before they escalate into something much larger. There may be a cost for a tune-up, but the peace of mind they provide a car owner with is priceless, especially if an issue is found and corrected in a timely manner.
