The Difference Between MFI & MPI

Cars and acronyms may go together like peas and carrots, but the resulting alphabet soup could drive Buddha to fits. So you're excused for feeling a bit like a monkey at the prom, and wanting to ram a sock down your own throat in frustration when trying to tell the difference between terms like MPI and MFI. Especially these terms, which, like so many others, since they can often refer to the same kind of system using slightly different nomenclature.

TBI vs Multipoint Injection

  • The old throttle body injection system, or TBI, is something of an evolution of the carburetor, a stop-gap engineered to help manufacturers transition from carburetors to the electronic fuel-injection systems used today. The TBI unit bolts in place of the carburetor and sprays fuel under pressure into the engine. A multipoint system uses one injector for each one of the engine's cylinders. These individual injectors spray fuel directly onto the back of the intake valve, ensuring perfect fuel distribution to each cylinder.

MPI vs. MFI

  • In the common parlance, MPI and MFI are actually two different ways of referring to the same system. MPI breaks down as "multipoint injection," and MFI stands for "multipoint fuel injection." You could also abbreviate the latter as MPFI, MI or Fi. BMW originally dropped all but the last letter when referring to the same system and still uses the old "-i" suffix in spite of the fact that the company no longer manufactures a car without fuel injection.

MFI — Definition 2

  • The acronym MFI can also refer to mechanical fuel injection, a system in use since the earliest days of internal combustion. The primary difference between carburetion and fuel injection is that the former uses engine vacuum to suck fuel into the cylinders, while the latter sprays fuel into the engine under high pressure. A mechanical system is just that: it uses no electronic controls whatsoever, relying either on a fuel pump — as many diesels do — or a fuel distribution system to time fuel injection to crankshaft position.

EFI

  • Electronic fuel Injection differs from mechanical fuel injection in that it uses some sort of electronic controls to time the fuel injection cycle. The most basic type of EFI system consists of an oxygen sensor and a small control box that controls an auxiliary air valve. The fuel injection system is essentially mechanical, and the engine controls the air-to-fuel ratio by making minute adjustments the the amount of air going in. The modern EFI system uses a legion of sensors and electronic injectors to control how much fuel goes in and when.

BUYNOW-BUTTON2 $90.00

Optoelectronic isolated RS232/MPI,Siemens S7-300/400 PLC Programming adapter cable,with communication indicator,can replace Siemens 6ES7 972-0CA23-0XA0,automatically adjust the communication speed from 19.2Kbps to 115.2Kbps for the PC port,automatically adjust the communication speed from 19.2Kbps to 187.5Kbps for the MPI interface.Can connect PLC and the touch panel of third party factory to communicate.It doesn't support profibus function.

PC/MPI+ adapter, or named PC adapter, could achieve the level conversion of RS232 to RS485 and the protocal conversion of RS232 to MPI(MultiPoint Interface).PC/MPI+ is the adapter of photoelectric isolation type towards industrial design. Between RS232 port and RS485 port exist the surge protection and anti-lightning protection circuit, adaptable to the full PLC series of Siemens S7-300/400 and those devices with MPI port, especially the industrial fields with greater interference and easily damaged communication port. All kinds of protection measures in the circuit give promission to the safe operation of the system.

PC/MPI+ can make touch-screen communications with the third party under the link of S7-300/400PLC, such as eView, Wei-lun and kun-lun state.

Characteristics and main technical parametres:

★ Power: It is supplied by the 24VDC MPI port of PLC, power consumption of about 1w, with overcurrent protection and surge protection.
★ Isolation Voltage: 1000VDC(Maximun to 3000 VDC, orders require statement.)
★ RS232 port has anti-surge protection, RS485 port has anti-lightning protection and overcurrent protection with the consumption of 500w.
★ RS232 port baud rate: 19.2Kbps—115.2Kbps, automatically adaptable to the standard baud rate.
★ MPI port baud rate: 187.5Kbps—19.2Kbps, automatically adaptable.
★ Supporting the connection of PLC to touch-screen communication with the third party.
★ With a power indicater light, on-line and data transmission indicater light.
★ Working temperature: -20~75'C
★ Dimension: 103×50×26; After connecting the RS232 cables: 5.5m.

Software settings of STEP7:
Entering the main interface of STEP7 programming software(SIMATIC Manager), clicking on “Options” menu under the “Set PG/PC Interface…” option into the PG/PC interface settings.
1. Double clicking on “PC Adapter(MPI)” into the RS232 interfaces and MPI set of parameters. The adapter does not support “PC Adapter(PROFIBUS)” option.
2. Clicking on “Local Connection” option set RS232 interface parameters, choosing PC/MPI to connect on the port of COM correctly, and it will adapt to the chosen baud rate automatically, both 19200bps and 38400bps of RS232 communication.
3. Clicking “MPI” to set port parameters of adapter MPI, acceptable at both 187.5Kbps and 19.2Kbps, and the adapter will adapt to its baud rate automatically. Others have already been set.
4. On-line test accessing point: Using PC/MPI to connect to MPI port and RS232 port of the computer. And then click on the button in the red circle as follow, if appearing the data inside the red line, the test has passed. Then one could operate on it.

The long-distance communication of PC/MPI+ adapter:

1. To extend the distance of RS485 port

2. To extend the distance of RS232 port

RS232 Cable:When you buy PC/MPI+,we will give you the free RS232 Cable.

ABCD

A cable is most often two or more wires running side by side and bonded, twisted, or braided together to form a single assembly, but can also refer to a heavy strong rope. In mechanics, cables, otherwise known as wire ropes, are used for lifting, hauling, and towing or conveying force through tension. In electrical engineering cables are used to carry electric currents. An optical cable contains one or more optical fibers in a protective jacket that supports the fibers.

Electric cables discussed here are mainly meant for installation in buildings and industrial sites. For power transmission at distances greater than a few kilometres see high-voltage cable, power cables, and HVDC.
