What are the advantages of project unigauge?

Project Uni gauge is an ongoing exercise by Indian Railways to standardize most of the rail gauges in India at 1676 mm (5 ft 6 in) broad gauge. Project Uni gauge seeks to standardize the rail gauges in India by converting most of the Meter gauge and Narrow Gauge tracks to Broad Gauge track.ADVANTAGES1) Indian Railways have become more efficient,2) the current break of gauges can now be avoided3) the freight-carrying capacity has increased4) shortening of the routes with many regauged links has taken place5) A standard system has been established and there is uniformity when it comes to rail gauge.

What is logistics crossdocking?

Cross-docking is a practice in logistics of unloading materials from an incoming semi-trailer truck or rail car and loading these materials directly into outbound trucks, trailers, or rail cars, with little or no storage in between. This may be done to change type of conveyance, to sort material intended for different destinations, or to combine material from different origins into transport vehicles (or containers) with the same, or similar destination.

Where are solenoids used?

Solenoids are used in Car Starters, Rail road as electric switch. They are also used as valves to control the flow of fluid in appliance like washing machine.

Why injection pressure is high for diesel engines in common rail direct injection?

In common rail direct injection (DICOR) engine used in multicylender & main function is to provided the fuel in equal amount of in all cylender & the pressure of the fuel is high for atomised (Vaporized) the fuel & these atomised the fuel is reduces the knoking problem.Regarding this high pressure is use.

What is Common Rail Engine?

This a type of injection system that all the injectors are run off one high pressure source. Most current diesels are Common rail direct injection engines.

What are the constructional differences between an electronically controlled diesel system and a common rail diesel fuel system?

This question is kind of vague. Common rail diesel fuel systems are electronically controlled. A common rail fuel system has a high pressure pump that supplies the fuel at very high pressure to a single or common volume that all of the injectors are connected to. The injectors are then electronically signaled to operate, and draw their pressurized fuel from the common rail. The amount of fuel delivered is controlled by the injector. This system is somewhat similar to your port injection gasoline engine, but at much higher pressures. An electronically controled diesel that isn't common rail will have an injection pump that supplies high pressure fuel to each injector individually. The amount of fuel delivered is controlled electronically by the high pressure injector pump.

How does common rail diesel engines work?

A common rail diesel engine is similar to a conventional diesel engine, only difference being the fuel injection system(FIS).The common rail direct injection system uses electronic circuits to control the amount of fuel that is injected in to the cylinder. Also the time of injection(TI), Start of injection (SOI), Injection quantity (Q), and the injection pressure (P) are all accurately controlled with ecu in this technology. A high pressure pump(HPP), driven from Engine shaft, is used to pump in high pressure fuel from the tank and deliver it to the common rail. A common rail is nothing but a hollow shaft to which the fuel is delivered and maintained at a very high pressure of about 2000 bar.during the firing sequence of that particular cylinder, the high pressure electronically operated injector will be opened and fuel with a pressure of about 2000 bar is injected in to the cylinder. This high pressure fuel cloud will be automised completely and leads to complete combustion of the fuel, thus avoiding emission.

Would a faulty injector stop a BMW 3 series diesel from starting can it start on 3 injectors?

The 3 series BMW uses a common rail diesel injection system. This means a high pressure pump provides diesel to a common rail feeding all 4 injectors. If one injector goes down there can be insufficient pressure to start the car. The 3 series BMW uses a common rail diesel injection system.

What size engine is your 2003 dodge ram 2500 diesel?

What is the meaning of system common rail?

The new technology for diesel and some gasolene injection is Common Rail Injection In the old days each injector was pressured individually, on most units by a single pump with the same number of pump pistons ans the engine had cylinders. Each with there own high pressure fuel line. The new way is to have one very high pressure pump and control the injectors electronically. All the injectors are fed by one high pressure "common rail" or line This allows higher fuel pressures, better and more accurate fuel control making for lower emissions and higher fuel economy.

Why rail pressure goes high when engine is on?

Engines need higher fuel pressure to start than they do to run.

What does dci mean in cars?

dCi mean "direct common-rail injection". The Renault user manuals also state "high pressure" in brackets as clarification. So, often combined with a turbo, its a way of getting fuel into the engine under high pressure to increase efficiency and therefore economy. The injection method is "common" in that all cylinders share this same chamber of consistant, pressurised fuel. This is also refered to as HDi and CDR. It's the high pressure fuel rail and the computer controlled electronic injectors that make all the difference. In the common rail system, the fuel pump charges the fuel rail at a pressure of up to 25,000 psi--but unlike old indirect injection pumps--it is not involved in fuel discharge. The computer controls the release of tiny jets of compressed gas directly into the cylinders.If you mean in Roman numerals then it is equivalent to 601
