Injector leads and boots make it as easy as soldering and heat shrinking. The 2009 Nissan Sentra refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank, through the evaporator, and back to the compressor. It's a little more complicated that it seems and I'm not 100% sure about the components on the circuit board. As luck would have it, he forgot to list the cable with the auction and sold it to me. Fortunately he gave me the part number and I contacted Bosch and eventually located someone familiar with the unit. These days, if we can find a factory fuel injection harness in any condition it is a miracle.
There's also , who built a neat breakout box to test his wiring harnesses. Any help would be appreciated. This schematic shows typical diagram of Motronic engine system. He was selling the same tester on eBay and wanted to provide a copy of the manual to the winning bidder. Integrated ignition coil on distributor and remote ignition coil designs are used depending on model. It seems there are several versions of the Bosch Manual. Variable displacement compressor increases or decreases pressure as necessary to maintain evaporator temperature near 32°F 0°C.
Condenser with liquid tank 5. Later we'll list some common questions and links to the answers. The seminar will open in a new window. Outside air The Motronic is the trade name given to a range of digital engine-management systems developed by Robert Bosch GmbH, commonly known as Bosch. The Bosch manual is pretty bad but it gives you an idea of what accessories are available. Leaking fuel under high pressure can make one heck of a fire, so replacing these hoses should be the highest priority.
If you have a 530i, the vacuum hose routing can be confusing. The fuel system consists of: 1. Here's the English version which is much more complete than the sales literature. An important difference from D Jetronic was that no attempt was made to time injector pulses to individual cylinders or groups of cylinders. Bosch L-Jetronic Tester Bosch L-Jetronic Tester by Richard Atwell c Copyright 2003-2011 I've been looking for an L-Jetronic tester ever since I discovered excellent webpage documenting all the various testers he's located and collected.
Below schematic and wiring diagram shows Typical Toyota Ignition System for 1994 Celica. Switch closes when pressure increases to more than 34. Available for both d jetronic mpc and ljetronic afc , these boots and leads make an undetectable repair. That company is absolutely fabulous: not only did they tell me that they stopped producing that tester in 1989 but they mailed me an operating manual and some sales literature. The Fiat 127 is a supermini produced by the Italian automaker Fiat between 1971 and 1983.
Unlike D Jetronic with its complex throttle switch, for L Jetronic the switching functions associated with throttle movement are very simple - the system only senses closed throttle and full load conditions. However, in 1977 a new model range was introduced which included the option of a larger engine of 1049 cc capacity with a single overhead camshaft. The following schematic shows Honda Civic Hatchback 2002 — 2003 model years Fan and Radiator Parts Diagram. This has a clear advantage that compensation for individual engine differences due to build tolerances, wear and so on, is provided automatically, thereby solving a problem which can afflict manifold pressure sensing systems. It seems that Bosch, fearing that some potential customers might be suspicious of electronic control systems, wanted to hedge their bets and pursue both mechanical and electronic routes.
I've yet to identify the exact diodes used and the black object. The pressure drop across the injector nozzle was therefore maintained constant for better operating consistency. The authoritative manual on Bosch fuel injection. I've kept these images large so they are easier to read online. .
This system was designed to fully integrate and regulate all major engine system parameters, thereby enabling fuel delivery and spark timing control functions to be controlled by the same unit, in an attempt to achieve optimum efficiency, driveability and power output potential. If pressure decreases to less than 17. You will find specific information on the newest ke-motronic and lh-motronic systems that is not available from any other source. You can locate the battery clamps easily I bet. Speaking of age related problems, the fuel hoses crack with age.
An Alfa Romeo mechanic sent me a portion of a test manual that covers testing an L-Jet Alfa using our Bosch tester. Available for both d jetronic mpc and ljetronic afc , these boots and leads make an undetectable repair. I have expended a great deal of time and expense researching and collecting it. Injector leads and boots make it as easy as soldering and heat shrinking. The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion valve, located inside the evaporator case. I gladly duplicated it and sent it along to him and for a lark wondering if he'd seen the supplementary cable that tests the fuel injector firing frequency. Some less endearing features of D Jetronic, the trigger switches and inductive manifold pressure sensor, were dispensed with and, instead of running at constant gauge pressure, fuel pressure was referenced to manifold pressure via a vacuum connection.
A much improved system of connectors, which with only detail alterations has become widely used on most later systems, was also introduced with L Jetronic. Then calculates opening duration of injectors. An auxiliary shaft, driven by the toothed camshaft belt, is used to drive the distributor and the fuel pump. The sales sheet gives you a basic idea of what the unit does but it's not very descriptive. Another first for L Jetronic was the use of Lambda feedback from an exhaust oxygen sensor to achieve accurate stoichiometric fueling in conjunction with a 3 way catalyst. Heated front screen, Radiator fans speed control, Fuel injection, Canister purge valve, Airflow meter, Automatic transmission control module, Traction control system, Anti-lock bracking system, Right Hand Beam, Front Fog Light, Master Light Switch, Inlet manifold turning valve, Canister close valve, Windscreen washer pump, Wiper motor, Ignition coil, Vacuum module, Battery backed sounder, Dip beam, Master light switch, Head light leveling, instrument panel, Engine control module, throttle motor relay, Oxygen sensor heater, Power wash pump. Instead two pulses per cycle one per revolution were provided which experience had shown to give quite acceptable response and drivability without being referenced to any particular part of the cycle.
