General Information On Diesel Engines
of any other large internal combustion engine. The
fact remains, two-stroke diesels with high pressure
forced induction, particularly turbo charging, make
up a large percentage of the largest diesel engines.
Throughout North America, diesel engines are generally
used in larger trucks, where the low stress, high
efficiency cycle will lead to a much longer engine
life and lower costs to operate. These advantages
also help to make the diesel engine ideal for use in
the heavy haul industry.
Cars however, continue to use gasoline, primarily
due to the consumer desire for a wider range of
RPM. In Europe, the use of diesel engines with cars
is far more common.
Even though diesel engines are more efficient when
throttled down, they aren't suitable for most types
of aircraft. The higher compression ratios of the
diesel cycle demand a much stronger block, head,
and almost all moving parts in general. These
stronger parts add a lot of weight, or a lot of
expense, especially if lighter alloys are being used.
The Otto cycle engines are much cheaper to build for
these reasons, although they have long been overtaken
by the turbine engines. For the same displacement
of the engine, Otto cycles will produce more actual
power than a Diesel cycle can, because the fuel
will burn at a much faster rate, allowing more power
strokes per minute than a standard diesel can offer.
What this means, is that less fuel has to be carried.
Additionally, commercial aircraft is normally run
at preset limits, so that Otto cycle engines used
in aircraft don't suffer anywhere near the efficiency
penalties that land vehicles do. Heavy equipment,
such as those used in mining and construction,
almost always uses diesel engines.
Diesel engines are also used with submarines. In
these types of submarines, the diesel engine is run
when the submarine is on the surface, which charges
the batteries that power the submarine once it is
All across the world, diesel engines serve many
different purposes. They are used with almost all
types of heavy machinery, and other vehicles. Gas
isn't the way to go with heavy machinery, as the
engines simply can't withstand the beating.
Diesel has been popular for many years with machinery
and submarines, simply because the engines can
last for years and years. Although they won't offer
as much speed as gasoline, the torque and power is

Diesel Engines Forgotten Treasures
Diesel Or Not
Diesel is often looked at as being smelly, noisy, and many think the only place for it is in a tractor. The truth to diesel vehicles is that they are slow, noisy, smelly, although they are cheaper to run than gas. Diesel engines aren't...
As you probably already know, diesel engines get better fuel economy than gas, simply because they don't need to burn as much fuel as gasoline engines to get the same amount of power. Diesel engines are built heavier than gas engines, to...
Gas Versus Diesel
Cost Due to the high compression ratios and resulting high cylinder pressure in diesel engines, they must be built to withstand a lot more punishment than gas engines. The parts that are spruced up include a thicker block and cylinder...
Gas VS Diesel Boats
As you may know, diesel engines aren't something you should take lightly. There are good reasons why the rush to put them in cars back in the 70s flopped. Diesel isn't the ideal power source for all applications. Engine speed ...
General Information On Diesel Engines
Diesel engines offer the lowest specific fuel usage of any other large internal combustion engine. The fact remains, two-stroke diesels with high pressure forced induction, particularly turbo charging, make up a large percentage of the...
How Diesel Engines Work
When gas is compressed, the temperature of it will rise, with diesel engines using this very property to ignite the fuel. Air is then drawn into the cylinder and compressed by the rising piston at a much high compression ratio than gas...
Hydrogen Boosted Gas Engines
With the ever increasing cost of gasoline prices, auto makers are having to work overtime to cost effictively improve the fuel economy, while still meeting the strict emission requirements of today with gasoline engines. One ideal and...
Most Fuel Efficient Vehicles
Most efficient overall - Honda Insight hybrid With 60 mpg city and 66 mpg highway, the Honda hybrid has top honors as most fuel efficient in the United States. With a 1.0 gas engine mated to an electric motor, the insight was designed to...
Why People Use Diesel
With diesel engines, the compression ratio is higher and there is more power. From a technical point, the compression ratio of an engine is the comparison of the total volume of the cylinder at the bottom of the piston's stroke divided by...
Why You Should Choose Diesel
The major distinction between diesel and gas lies in the type of ignition. While gas engines operate on spark ignition, diesel engines employ compression ignition for igniting the fuel. With compression, the air is drawn into the engine...
