The economies in operation must be set over against the original cost. The Diesel engine ship is in many ways a much cheaper carrier than the steam boiler ship, which is a glutton for oil fuel.
It is worthy of note that larger internal combustion oil ships are taking the sea every month. The tremendous economy it is possible in the marine consumption of fuel-oil demands the immediate adoption of Diesel engine if the world wants to make the largest use of its oils resources for the longest time. The Declaration of Diesel Engine motor ships were used in merchant marine. To accomplish something with the Diesel Engine ship at least in the latter part of service when the demand for shipping had given way to entirely merchant marine program. Diesel engine ship has its advantages greater cargo capacity; reduction of labor in engine room; increased cruising radius. Diesel Engine Ships can go round the world with the oil in their tanks. Using a very old idea that has already proven itself in locomotives. In essence, a diesel electric power plant includes a diesel engine connected to an electrical generator, creating electricity that powers electric motors. Traditional electric propulsion systems have been heavy, and cumbersome. Diesel electric systems are now lighter, and less expensive. Due to the ongoing effects of pollution, environmentally friendly propulsion systems are being heavily evaluated. This type of power plant is the remedy for highly polluting traditional forms of yacht propulsion. This is one of the reasons why Lagoon has chosen to incorporate this system into one of their latest yachts. Diesel Engines have much more to evolve to this coming year.

In the transportation industry there are two major types of engines. These are the diesel engine and the gasoline engine. The diesel engine can be found more commonly in the larger vehicles such as buses and trucks but the gasoline engine has remained the most popular engine in cars. There reason for this may not be clearly apparent at a first glance as it seems that the only difference in the engines is the fuel type. This is however a large misconception as the inner workings of the engines also differs.

There are however some overlapping areas. These include areas that can be used by manufacturers to produce the best vehicle engine in terms of efficiency and power. The two types of engines are similar in terms of the fact that they both contain cylinders. The number of cylinders however may vary from engine to engine and is largely determined by the make of the vehicle they are designed for.

There are three main configurations that the cylinders are arranged in. These are the inline, the V or the flat. The inline design has the cylinders arranged in a line in one bank. The V design sets the cylinders at opposing angles and they form the V shape to one another. The flat design also called the boxer or horizontal design sets the cylinders horizontally opposed. The configuration chosen is dependent on the car as the advantages and disadvantages can vary.

Another similarity is the combustion cycle. There are four stroke combustion cycles that are very much similar in the two engine designs. These strokes are the intake, compression, combustion and the exhaust strokes. These strokes are almost identical in the two engine types and can be seen to be the cycle by which the engines operate to produce power. The two engines also have a crankshaft that is used to open and close the valves in the combustion cycle.

While the fuel type remains the largest difference between the diesel and gasoline engines it is not the only difference. The fuel differences however are based on the combustion ratios at which the fuels will combust or explode. The gasoline will not self-ignite as there is not enough heat generated for combustion to occur. This is why there is the need for a spark plug that causes the explosion that is necessary. The diesel however requires no spark plug and will ignite when compressed.

Diesel engines therefore have much higher compression pressures than the gasoline engines. This difference is due to the fact that air alone is compressed in the diesel engine and therefore the fuel goes directly into the cylinder and allows the compression ratio to be much higher.

It is seen that the fuels also differ in the amount of carbon and hydrogen atoms. The diesel fuel has more carbon and hydrogen atoms than the gasoline making it more energy dense than the gasoline and therefore providing more energy per gallon when compared to gasoline.

In terms of efficiency it can be seen that the two engine types vary significantly from one another. It can be argued that the diesel engine is the more efficient of the two engine types. There are however some drawbacks to the diesel engine in terms of environmental issues as well as noise.

It has been 114 years since Rudolph Diesel applied for a patent for his new improved engine. It was hoped to replace the gasoline engine but as we can all see that this has not happened. The gasoline engine having just been invented in 1876 was still considered inefficient in fuel consumption and power. An evaluation of each engine’s performance tells a story that is difficult to reconcile with the way things have shaken out in the beginning of the 21st Century. The invention of the Diesel offered the world a far more efficient and effective fuel based engine. It actually provides more horsepower per gallon or liter than a gasoline. This is why diesel engines power our large earth moving equipment, trucks, marine engines, low mileage cars and now aircraft.

The diesel is a combustion injection engine. Unlike the gasoline engine, air is compressed first and then the fuel is injected into it. The compressed air is hot enough to ignite the diesel fuel without the use of a sparkplug. Diesel engines developed out of the earlier work surrounding two engines; the original diesel design and the solid injection system of Herbert Akroyd Stuart created in his hot bulb engine. This means that the upward stroke of the diesel engine compresses the air to where its’ temperature is between 1300-1650° F. When the piston has reached the top of its’ upward stroke, diesel fuel is then injected, combustion occurs, pressure increases and pushes the cylinder downwards. This motion is transmitted by means of the connecting rods to the crankshaft which itself turns thus transmitting rotating power to a drive shaft which powers ships, cars, generators, aircraft and even motorcycles.

During cold weather, diesel fuel thickens when the wax crystallizes. It becomes a gel and the fuel injection will not easily work. Technological advances have made this a problem of the past. The fuel lines and fuel filter can be pre-warmed, others use a glow plug in the combustion chamber to pre-heat its’ walls, some use resistive heaters in the intake manifold to warm air taken into the combustion chambers and engine block heaters are used in areas like Kansas or Nebraska when automobiles are left in the cold overnight.

Diesel engine speed used to be controlled by governing the rate of fuel through a gear system. Today the use of electronically controlled engines ECM (electronic control module) allows diesel engines to adjust their timing to start according to the environmental conditions of heat and cold, regulate the engine speed in terms of RPM (revolutions per minute) and maintain fuel economy.

Diesel engines may not have beaten its’ chief contender, the gasoline engine, but it has kept ahead in terms of heavy machine and naval engines. It has recently performed outstandingly in the area of remotely piloted vehicle engines, set amazing land speed records for racecars and motorcycles. The diesel engine has improved amazingly in the past 114 years. The use of electronics has given all engines abilities of fuel conservation unheard of in past years. This makes the diesel engine a real budget-winning contender. This year the new 2006, Volkswagen diesel won fourth place in the best mileage evaluation according to http://www.fueleconomy.gov. Diesels may prove to be the green vehicle engine of choice in the future since they have very little carbon monoxide emissions. Catalytic converters and diesel particulate air filters have made diesel engines free from particulate, nitrogen and sulfur oxides. Diesel engines may prove to be the easiest solution to greenhouse gases.

Traditionally the diesel engine was both slow and noisy, suitable only for tractors, trucks and ships, but the trend in recent years has been for high performance diesels to take a large proportion of the car market away from the petrol engine car. Part of this change was the evolution of the high performance turbo diesel, and the popularity of these vehicles has been further improved by a healthy market for performance parts available to the Diesel performance tuning enthusiast.

One popular option has been the remapping of the fuel injection and ignition system using a variety of techniques to get the best performance out an engine without resorting to the cost of physically tuning the engine of the car.  A factor behind this appears to be the deliberate de-tuning of many cars by the manufacturers, supposedly for reasons of economy, but some say more cynically to leave a niche in the market for higher performance petrol models.

Here we take a quick look at how the remapping system works, and the general effects on a typical diesel engine.

A modern diesel engine’s functioning is almost completely controlled by the electronic system that manages the fuel injection and ignition functions.  These systems have a number of sensors which are controlled by the vehicles ECU.  These signals are processed many thousands of times each second to keep the vehicle running at its optimum efficiency, and also to keep the engine’s emissions at acceptable levels.

The idea behind a diesel tuning box is to intercept the signal between the ECU and the injection system, and basically allows it to inject a more optimal amount of fuel into the cylinders thus producing more torque and power.  Because of this the engine runs more efficiently.  Fuel economy is also improved because you would have to use less throttle to achieve the same performance level, and because the engine is tuned to burn its fuel more efficiently.

To understand how the tuning box works it is important to understand the workings of a diesel engine.  

In a diesel engine it is only air that is drawn into the compression cylinder.  This is then compressed and reaches a very high temperature. When the piston is nearing the top of its stroke fuel is injected into the combustion chamber and ignites due to the high temperature of the air.  This creates the power to drive the piston down, turning the crankshaft and wheels.

Often there is unused air left in the cylinder after the combustion completes:   sometimes as much as 50% of what was drawn in to the engine.  Simply speaking when the correct amount of extra fuel is injected into the chamber more torque and power and is created. 

The ìcommon railî is the central container which delivers the individual injectors with the fuel.  The three essential components of a fuel injection system:  Pressure, injection and generation are separated, and fuel can be stored at high pressure in the ëcommon railí container.  This allows high injection pressure even at slow speeds and provides a fine atomisation of the fuel, which gives a cleaner combustion.  The supply of fuel is not related to the engine speed as it is controlled independently at every point along the way improving efficiency.  

So in the modern common rail system engine there is greater opportunity to control fuel injection at the pre-injection stage. The main vehicle’s engine control unit  (ECU) is the brain of the system, which opens each injector electronically, these signals are processed many thousands of times in one second to maintain that the vehicle is running at its optimum efficiency and keeping the emissions and economy at acceptable levels.  The ECU contains a ìmapî which tells the fuel injection system, for every engine speed and setting, how much fuel to inject into the engine.

A similar unit is usually used to tune a large number of diesel vehicles but different settings are uploaded into the unit.  

When the box is plugged into your vehicle it will analyse the ECU signals and alter them.  This allows changes in injector opening times which increase or decrease the fuel rate to exactly the right amount, thus producing more torque and power. 

Using latest digital diesel tuning technology an electronic control unit can give a driving performance so individual that it as though the original control unit software has been completely changed.  Four to eight ignition maps are placed in the memory for the first time that then go into action according to your required driving performance. This means the optimal matching of all control parameters at every level of performance. 

A further novelty is the ability of the systems to adapt to the individual characteristics of your vehicle.  

Over a short running-in period, the memory function detects the individual data for the differing fuel injection cycles. The information gained in this way provides the basis for the optimization. The tolerances are then balanced and an optimal result is achieved with every vehicle without having to make any time consuming adjustments by hand. 

An enhanced ignition map leads to raised levels of efficiency, which in turn leads to reduced fuel consumption. The increase in torque facilitates a driving performance that requires fewer revs per minute and less accelerator pressure to achieve a given acceleration, therefore significantly lowering levels of fuel consumption.   Thus efficient diesel tuning can be seen to improve both the performance and the economy of a modern diesel engine.
