What does a warm up regulator do?
Warm-up regulator ensures that the engine runs smoothly when looking for one cold start slowly getting warm. It is directly connected to the motor so that it can measure the motor temperature directly as a controlled variable. The Bimetal spring is heated in the process.
What is the difference between K Jetronic and KE Jetronic?
KE-Jetronic (1985–1993) The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
How do you adjust K Jetronic fuel injection?
For early model cars using the K-jet (mechanical fuel injection) system, mixture adjustment is quite simple. A 3mm allen wrench is necessary to access the adjusting screw. Turning this screw to the right richens the mixture while turning it left leans it.
How does Bosch K Jetronic work?
The injection valves of the K-Jetronic work purely mechanically from an opening pressure of 3.3 bar. The amount supplied by the control piston pushes the valve needle open more or less and leads to a rattling noise. The valve needle vibrates in its seat due to the fuel flowing past.
How does K-Jetronic work?
An air enters to the air filter, then it enters into the engine cylinders through the air flow sensor and throttle valve. Therefore, the rotary-type fuel pump with electric drive supplies fuel from the tank. The fuel enters to the fuel accumulator through the filter.
How does LH Jetronic work?
Overview of L/LH-Jetronic Fuel Injection Systems In pulsed injection, all air entering the engine first flows through an air-mass meter. The air-mass meter measures the air, which indicates engine load, and converts that measurement into an electrical signal to the control unit (ECU).
How does K Jetronic work?
How does Bosch motronic work?
The Motronic units have 2 injection outputs, and the injectors are arranged in 2 “banks” which fire once every two engine revolutions. In an example 4-cylinder engine, one output controls the injectors for cylinders 1 and 3, and the other controls 2 and 4.
What is common rail fuel injection system?
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
What is the main difference between motronic and Jetronic engine?
As far as I can tell, the L-Jet and Motronic systems in the 75/164 (respectively) are very similar; air flap for measuring airflow, throttle position sensor, coolant temperature sensor, rpm, etc. It seems the only difference on the fuel side is the L-Jet is analog and the Motronic is digital.
How much pressure should a common rail injector have?
2,000 BAR – 29,000 PSI
Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.
What does common rail turbo diesel mean?
Common rail is a fuel injection system found in modern diesel engines. Common rail systems provide a level of flexibility which can be exploited for class leading emission control, power and fuel consumption.
Do they still make warm up regulators for Porsche 911s?
Bosch has discontinued most if not all of the original warm up regulators used in the CIS fuel injection system. This is an aftermarket electronic warm up regulator for the Porsche 911 CIS models, 1973.5 to 1983. It replaces the original mechanical style regulator and is a direct fit into the same location.
What kind of regulator does a Porsche 911 CIS have?
This is an aftermarket electronic warm up regulator for the Porsche 911 CIS models, 1973.5 to 1983. It replaces the original mechanical style regulator and is a direct fit into the same location.
What is the purpose of the warm up regulator?
The warm up regulator is crucial to the correct operation of the CIS Fuel system. Bosch has discontinued most if not all of the original warm up regulators used in the CIS fuel injection system.
