L-Jetronic ECU in breaker-triggered ignition systems by the contact-breaker points in the ignition distributor, and, in breakerless ignition systems, by terminal 1 of the ignition coil (Fig. 9). Measuring the air flow The amount of air drawn in by the en-gine is a measure of its loading condition. The air-flow measurement system allows, 6/17/2014 · 3. L – Jetronic Kode L berasal dari bahasa Jerman “Luft” yang berarti udara. Pada EFI L – Jetronic , kontrol injeksi dilakukan secara elektronik oleh Electronic Control Unit ( ECU ) berdasarkan jumlah udara yang masuk. Sensor untuk mengukur jumlah udara yang masuk ke dalam silinder adalah Air Flow Meter. C. Tujuan, L – Jetronic System – Fuel Injectors n Open when energized by ECU – not continuous as K – Jetronic . n Current through windings causes magnetism pulling armature and attached needle valve up and way from valve seat allowing fuel to flow. Can test with magnet on a stick. n All injectors are wired together and fire simultaneously,, 3/24/2016 · The L-Jetronic is an electronically controlled fuel injection system which has the advantage of direct air flow sensing. It injects intermittently into the intake ports. The task of a fuel injection system is to supply precise amount of fuel to the combustion chamber at that particular moment. … ( ECU ). The solenoid valve is provided with a …
How Car Parts Work: L-Jetronic Fuel Injection System, Jetronic – Wikipedia, Jetronic – Wikipedia, 7/4/2020 · Electronic Control Unit ( ECU } The most important unit in the ECGI system is the Electronic Control Unit ( ECU ) which is re sponsible for metering the fuel quantity. The items of information needed for this are collected by transducers (pressure sensors, temperature sen sors, etc.) and are fed as electrical quantities to the ECU .
7/1/2020 · Bosch D- Jetronic and L-Jetronic (ECGI ) Both of these Electronically Controlled Gasoline Injection systems ( ECGI) are almost identical ex cept for one feature. On the earlier D- Jetronic system, fuel delivery was regulated by an intake manifold pressure sensor. On the newest L – Jetronic system, the fuel delivery is regulated by the amount of air flow into…, 3.1 ECU connector. Not much is standardized in D- Jetronic connectors, but all of them have a 25 pin AMP connector with a spacing of 5.0 mm ( not 0.1 oder 0.2 inch), that connects them to engine wiring harness. Looking on that ECU connector, pin 25 is on the right side where wiring harness exits ECU , pin 1.
ultimately used in the Porsche 912E during the 1976 model year. The L – Jetronic was a further development of the D- Jetronic found in the Porsche 914 1.7L and 2.0L engines. The original L – Jetronic found in the 914 1.8L engine was further refined which resulted in the system installed in the 912E. The L – Jetronic
