Most commonly used commercial engine simulation packages generate detailed estimation of the combustion and gas flow parameters. These parameters are required for advanced research on fluid flow and heat transfer and development of geometries of engine components. However, engine control involves different operating parameters.

A diesel particulate filter DPF is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Some filters are single-use, intended for disposal and replacement once full of accumulated ash.

Its traditional strengths are economy, reliability and high-torque output. That is why it became established as the engine of choice for commercial vehicles a long time ago. The continuing development of the diesel engine — and particularly of the direct-injection design — coupled with the rapid advances made in high-pressure fuel-injection systems have consistently brought about further improvements in performance and consumption.

Furthermore, modern diesel engines with high-pressure fuel injection have made substantial progress in respect of driving smoothness and pollutant emission. They need no longer fear comparison with any other type of internal-combustion engine. This has led to the diesel engine becoming a much more popular choice for cars — including sports cars and luxury-performance cars.

With the increasingly widespread use of the diesel engine, the desire to understand more about it has also grown. It also describes the various Bosch fuel-injection systems. Consequently, it provides a comprehensive view of components in dieselengine management systems. This series of publications also includes other titles that examine in more detail the diesel fuel-injection systems and the electronic diesel-control system EDC outlined in this manual. Robert Bosch GmbH 4 Areas of use for diesel engines Suitability criteria, Applications Areas of use for diesel engines No other internal-combustion engine is as widely used as the diesel engine 1.

This is due primarily to its high degree of efficiency and resulting fuel economy. Diesel engines are produced as inline or V-configuration units. A lot more development work was required, however, before the first functional diesel engine was produced at MAN in Augsburg in An engine governor adjusts the quantity of fuel injected dependent on engine load.

For this type of application, mechanically governed fuelinjection systems are still used. Cars use fast-running diesel engines capable of speeds up to 5, rpm. The range of sizes extends from cylinder 5-liter units used in large saloons to 3-cylinder cc models for small subcompacts. Car and commercial-vehicle engines can also be used as fixed-installation engines. However, the engine-control system may have to be modified to suit the different conditions. Such engines, now almost exclusively fitted with turbochargers, offer considerably better torque characteristics than comparable gasoline engines.

The maximum torque available to a vehicle is generally determined not by the engine but by the power-transmission system. Cars and light commercial vehicles Car engines Figure 1 in particular are expected to produce high torque and run smoothly. Great progress has been made in these areas by refinements in engine design and the development of new fuel-injection with Electronic Diesel Control EDC.

Those advances have paved the way for substantial improvements in the power output and torque characteristics of diesel engines since the early s. And as a result, the diesel engine has forced its way into the executive and luxury-car markets. The ever more stringent emission limits imposed and continually increasing power demands require fuel-injection systems with extremely high injection pressures. Improving emission characteristics will continue to be a major challenge for diesel-engine developers in the future.

Consequently, further innovations can be expected in the area of exhaust-gas treatment in years to come.

That is why diesel engines for this type of application are exclusively direct-injection DI designs. They are generally medium-fast engines that run at speeds of up to 3, rpm. For large commercial vehicles too, the emission limits are continually being lowered. That means exacting demands on the fuelinjection system used and a need to develop new emission-control systems.

Construction and agricultural machinery Construction and agricultural machinery is the traditional domain of the diesel engine. The design of engines for such applications places particular emphasis not only on economy but also on durability, reliability and ease of maintenance. Maximizing power utilization and minimizing noise output are less important considerations than they would be for car engines, for example.

For this type of use, power outputs can range from around 3 kW to the equivalent of HGV engines. In contrast with all other areas of application, where water-cooled engines are the norm, the ruggedness and simplicity of the aircooled engine remain important factors in the building and farming industries.

Railway locomotives Locomotive engines, like heavy-duty marine diesel engines, are designed primarily with continuous-duty considerations in mind. In addition, they often have to cope with poorer quality diesel fuel.

In terms of size, they range from the equivalent of a large truck engine to that of a medium-sized marine engine. Ships The demands placed on marine engines vary considerably according to the particular type of application. There are out-and-out highperformance engines for fast naval vessels or speedboats, for example.

These tend to be 4-stroke medium-fast engines that run at speeds of It developed 20 horsepower at rpm. Compared with the conventional power units of the time steam engines and gasoline engines , this engine had a number of advantages: It used substantially less fuel which itself was cheaper to begin with and could be dimensioned for much higher power outputs. However, there were problems in achieving higher engine speeds. The more widespread the diesel engine became, and the more widely known its advantages were, the more insistent were the demands for a smaller, faster-running version.

The biggest obstacle to the development of a fast-revving diesel engine was the fuel supply system. In addition, the compressor required was very large so that size and weight could not be significantly reduced. In the latter part of , Robert Bosch decided to direct its attention to the development of a fuel-injection system for diesel engines. By the beginning of , around a dozen different designs for fuel-injection pumps had been produced.

The first tests of the system fitted to the engine started in the middle of that year. By the summer of , the design of the injection pump was complete. The first series-production units left the Stuttgart factory in Those Bosch fuel-injection pumps were the breakthrough in achieving higher running speeds in diesel engines. Since that time it has conquered ever wider areas of application. The first volume-production car to be fitted with a diesel engine was the MercedesBenz D in 2, cc, 50 hp.

One of the first series-production Bosch Type PE.. The engine had a capacity of 2, cc and produced 27 horsepower about 20 kW. At the other end of the scale there are 2-stroke heavy-duty engines designed for maximum economy in continuous duty. Such slow-running engines Engine characteristic data Table 1 shows the most important comparison data for various types of diesel and gasoline engine.

The compression ratio of such engines can be as much as At present they are of virtually no significance whatsoever within the overall picture, as they are incapable of meeting the current demands in respect of emissions and performance characteristics. Thanks to its turbocharger aspiration, aircraft with the new engine could reach altitudes of up to 14, metres.

In the s and s numerous two and four-stroke diesel engines were developed for use as aircraft engines. Apart from their economical consumption and the lower price of diesel fuel, diesels had a number of other features in their favor such as a lower fire risk and simpler maintenance due to the absence of carburetor, spark plugs and magneto.

Engineers also hoped that the compression-ignition engine would provide good performance at high altitudes. In those days, spark-ignition engines were liable to misfire because the ignition system was subject to atmospheric pressure. The most successful production aircraft diesel engine was the Jumo 6-cylinder two-stroke opposed-piston heavy-oil engine see illustration.

Following its introduction in it was fitted in numerous planes. It had a take-off power output of up to kW hp. Its strengths primarily lay in its suitability for long-distance flights at constant speeds, e. Around units of this reliable engine were built.

Diesel particulate filter

This contrasts with spark-ignition engines such as a petrol engine gasoline engine or gas engine using a gaseous fuel as opposed to gasoline , which use a spark plug to ignite an air-fuel mixture. The diesel engine has the highest thermal efficiency of any standard internal or external combustion engine due to its very high compression ratio and inherent lean burn which enables heat dissipation by the excess air. Diesel engines are manufactured in two-stroke and four-stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the s they have been used in submarines and ships.

Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту. Она вглядывалась в группы из четырех знаков, допуская, что Танкадо играет с ними в кошки-мышки. - Туннельный блок наполовину уничтожен! - крикнул техник. На ВР туча из черных нитей все глубже вгрызалась в оставшиеся щиты. Дэвид сидел в мини-автобусе, тихо наблюдая за драмой, разыгрывавшейся перед ним на мониторе. - Сьюзан! - позвал.  - Меня осенило.

Хоть и не очень охотно, она все же улыбнулась: - Что будем делать. Стратмор просиял и, протянув руку, коснулся ее плеча. - Спасибо.  - Он улыбнулся и сразу перешел к делу.  - Мы вместе спустимся.  - Он поднял беретту.  - Ты найдешь терминал Хейла, а я тебя прикрою.
