Oil Company has grown up really fast today. Oil Company promises a big chance for opportunity and in the same time providing the fuel that people need in their daily life and also the work opportunity for many people. The entire oil work such as in rig or in other processing oil field need the right equipment to make the process work and give the best result.

Oil Company has wide connection with other companies such as oilfield equipment companies, oil country tubular goods companies, and also oil service companies. People can look for the information about all of those companies in the internet since there are many companies that provide those product and services. For oilfield equipment the product that was provide in the market such as accumulator, chokes, lumber, mud pumps, stabilizer, testing equipment and many others.

For the oil country tubular goods, the product that was available are casing tubing, Coiled Tubing, drill collars, drill pipe, hevi-wates, kellys, pipe, miscellanous tubulars, pipe racks, and also pipe joints. Make sure choose the right company that was trusted and has a good track record in order to make the product or the goods will come safely in good conditions to the work place.

The Euro 6/VI regulations concerning greenhouse gas emissions from vehicles present manufacturers with the challenge of reducing several different gases using several different technologies incorporated into the same exhaust system. The reduction of NOX emissions alongside the reduction of CO2 has been a particular challenge for diesel engine manufacturers, and this has accelerated the advances in selective catalytic reduction (SCR) technology to meet NOX emission standards.

The Euro VI legislation due to take effect in 2014 requires an 80% reduction in NOX emissions compared with the Euro V standard. It is also expected that there will be a limit set for ammonia slip to control the amount of ammonia released from an SCR system. Several manufacturers are developing systems and components that aim to achieve such high levels of efficiency.

Delphi SCR dosing system

Delphi Automotive has developed an SCR system that improves performance and reliability of the system, as well as reducing NOX and CO2 emissions. The new system, due to be introduced in 2012, injects aqueous urea solution into the SCR system at up to four times the pressure of previous systems, and reduces CO2 by up to 1g/km when compared with similar systems.

The system is made up of three components. The SCR doser, which is an injector with high pressure pump, injects the urea solution directly into the exhaust at a pressure of 20 bar. The urea solution is fed to the doser by a low pressure pump situated in the Urea Delivery module (UDM). The whole process is controlled by the electronics and software used to manage the system.

Rather than use a timed injector opening, the Delphi system uses a positive displacement solenoid pump, which delivers accurate measured quantities of urea solution regardless of the supply pressure.

The stringent standards that are set out in Euro 6/VI legislation for NOX emissions reduction will be followed by even stricter targets for 2020 when details of the EU’s Euro 7/VII regulations are announced. Manufacturers of vehicles, engines, and SCR systems are researching and developing systems and components which can improve performance and efficiency, to enable them to meet these standards.

New innovations in components are being designed continually as the industry gathers pace, and two of the most recent advances are detailed below.

Delphi SCR ammonia (NH3) sensor technology

Due for initial production in 2012, Delphi has developed an ammonia sensor for the automotive industry, which enables more efficient emissions control. The system allows the SCR to work at optimized NOX conversion rates, which in turn improves fuel efficiency.

The sensor dynamically measures the content of ammonia in emissions and the system can adapt the urea dosage accordingly. Some existing SCR technology use a timed urea dosing process; without accurate means of measurement and control excess and residual ammonia can escape via the exhaust stream. It is anticipated that part of the EU directives will relate to the control of ammonia slip from SCR systems, so the monitoring of ammonia levels will soon be an essential requirement.

The ammonia sensor is placed downstream of the SCR catalyst and NOX sensor; it detects the levels of ammonia in the exhaust stream over a range of 0-100ppm. The sensor converts the ammonia into an electrical signal that the electronic control system uses to control the urea solution dosage.
The ammonia sensor is the first technology that enables an SCR system to have a direct closed loop control system; allowing the optimisation of the urea dosage to be controlled by measurement of the emissions.

Future innovation and design

SCR systems have been developed and improved upon very quickly since the EU implemented their emissions strategy and the standards for the industry to comply with. To develop SCR systems to meet requirements of Euro 6/VI regulations, and systems that can be used beyond 2020, manufacturers will require more innovative designs to provide even greater efficiency.

The brakes are the single most important thing on our vehicles. While all of the parts are required to get us moving, these are the parts that are truly designed to keep us safe. We often need to go in to have our brakes checked and have our brakes repaired because of the strong wear and tear that they will see over the course of the life of the car. Quick repair is important to get you back on the road and to keep you as safe on the road as possible.

While brake repair is important, it has a few important qualities that all drivers should understand. Knowing the importance of having your brakes done quickly will encourage you to be vigilant about brake maintenance.

• Catching Small Issues and Problems

It is generally most important for those who notice that they have small issues with their brakes. These people generally need their pads replaced but do not have any other problems with their brakes.

This is important for car owners in the sense that it keeps them from dealing with larger brake issues down the road. If you look for quick repair now, you can avoid bigger problems that will require more expensive repairs later on in the life of the vehicle.

• Keeping You Safe on the Road

It is important in the sense that it keeps you, and others, safe on the road. It works to make sure that your brakes work properly, which will allow you to avoid accidents on the road. It can give you this safety and do it quickly and efficiently.

• Getting You On the Road Quickly

While you may think about fixing your brakes yourself, you should give serious consideration to quick brake repair. This repair is going to happen at lightning speed, and will get you back on the road as quickly as possible. Most shops are going to be able to handle quick brake repair in an hour or less (assuming they have a time slot opening).

If you notice that you are having some trouble with your brakes, take your vehicle in to a shop as soon as possible. The shop will be able to show you exactly what is wrong with your brakes and what type of brake repair you will need to get them in perfect working condition.
