DENSO Develops a New Diesel Common Rail System With the World's Highest Injection Pressure

Farooqi, B. Snyder, S. This paper presents the development, experimentation, and validation of a reliable and robust system to monitor the injector pulse generated by an engine control module ECM which can easily be calibrated for different engine platforms and then feedback the corresponding fueling quantity to the real-time computer in a closed-loop controller in the loop CIL bench in order to achieve optimal fueling. This research utilizes field programmable gate arrays FPGA and direct memory access DMA transfer capability to achieve high speed data acquisition and delivery. This work is conducted in two stages: the first stage is to study the variability involved in the injected fueling quantity from pulse to pulse, from injector to injector, between real injector stators and inductor load cells, and over different operating conditions.

The first generation system offers manufacturers a cost-effective, robust solution to help them achieve optimal fuel efficiency and meet stringent emissions standards, such as Euro 4. Delphi is developing a second generation system to help manufacturers meet emissions standards for Euro 5, Euro 6 and beyond. Key features of the Delphi Diesel UPCR System include fast solenoid diesel injectors and a common rail, a program-tailored engine control module ECM , robust unit fuel pump with an inlet metering valve , as well as an efficient, low cost fuel filter. Low cost engine management system designed to provide the necessary high value essential to the market success of entrylevel market products and economy segment vehicle programs. Compact package size enables relative ease of application in very small engine programs.

The electronically controlled fuel injection system of the diesel engine has multi-disciplinary characteristics and strong coupling. The programming method based on a mathematical model cannot be applied to the fuel system with a diversified structure arrangement. With the rapid development of hydrodynamics, more and more simulation software is applied in the actual research. Hydsim simulation platform is one of the best software for the simulation of the electronic control injection system. In this paper, the Hydsim simulation platform is used to simulate the electronic control injection system, and a test-bed for verification is built. Based on the experimental results, the injection characteristics of high-pressure common rail are studied. The validity and accuracy of the simulation model are verified by comparing the simulation value with the test value and the standard value.

Common Rail Fuel Injection: Key technology for clean and ... - MTU

Common Rail Fuel Injection: Key technology for clean and Common Rail Fuel Injection :. Key technology for clean and economical combustion. Fuel is injected into the combustion. In , with the Series engine, MTU was the first manufacturer of large. The per for mance and flexibility of the CR system create the prerequisites for clean and efficient combustion. MTU divides the fuel injection sequence into as many as three separate phases.

Fuel injection is the introduction of fuel in an internal combustion engine , most commonly automotive engines , by the means of an injector. This article focuses on fuel injection in reciprocating piston and rotary piston engines. All Diesel compression-ignition engines use fuel injection, and many Otto spark-ignition engines use fuel injection of one kind or another. Mass-produced Diesel engines for passenger cars such as the Mercedes-Benz OM became available in the late s and early s, [1] being the first fuel injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early s, and gradually gained prevalence until it had largely replaced carburetors by the early s. The term "fuel injection" is vague and comprises various distinct systems with fundamentally different functional principles. Typically, the only thing in common all fuel injection systems have is the lack of carburetion.

High-pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, [ citation needed ] by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. This provides improved vaporization from the surface of the fuel droplets, and so more efficient combining of atmospheric oxygen with vaporized fuel delivering more complete combustion.

Diagnostics and Identification of Injection Duration of Common Rail Diesel Injectors

 Надо вырубить все электроснабжение, и как можно скорее! - потребовала Сьюзан. Она знала, что, если они не будут терять времени, им удастся спасти эту великую дешифровальную машину параллельной обработки. Каждый компьютер в мире, от обычных ПК, продающихся в магазинах торговой сети Радиошэк, и до систем спутникового управления и контроля НАСА, имеет встроенное страховочное приспособление как раз на случай таких ситуаций, называемое отключение из розетки. Полностью отключив электроснабжение, они могли бы остановить работу ТРАНСТЕКСТА, а вирус удалить позже, просто заново отформатировав жесткие диски компьютера. В процессе форматирования стирается память машины - информация, программное обеспечение, вирусы, одним словом - все, и в большинстве случаев переформатирование означает потерю тысяч файлов, многих лет труда. Но ТРАНСТЕКСТ не был обычным компьютером - его можно было отформатировать практически без потерь.

 - Прости меня, Мидж. Я понимаю, что ты приняла всю эту историю близко к сердцу. Стратмор потерпел неудачу. Я знаю, что ты о нем думаешь. - Это не имеет никакого отношения к Попрыгунчику, - резко парировала. Вот это чистая правда, - подумал Джабба.

 А вдруг Танкадо умнее. - Может.  - Сьюзан пожала плечами, демонстрируя равнодушие.

 Вы хотите дать взятку представителю закона? - зарычал. - Нет, конечно. Я просто подумал… - Толстяк быстро убрал бумажник.

Этот волшебный вечер был шесть месяцев назад, до того как Дэвида неожиданно назначили главой факультета современных языков. С тех пор их отношения развивались с быстротой скольжения по склону горы. ГЛАВА 4 Потайная дверь издала сигнал, выведя Сьюзан из состояния печальной задумчивости. Дверь повернулась до положения полного открытия.
