E4 4CYL Injectors Emulator

E4 4CYL Injectors Emulator 

Injector's emulator "E4" is destined to cut-off a petrol by turning off injectors in four-cylinder engines equipped with LPG fuel supply installation of motor vehicles.

Disconnection of injectors takes place in the moment of power supply switching over from petrol to LPG with fixed delay from 0 to 5 sec. settled with potentiometer, accessible after stopper removal placed in bottom parts of device.

During the fixed delay both kind of fuel are loaded to prevent engine stops or jerks during fuel switchover. After disconnection the injectors are emulated to prevent error messages from on-board computer showing damage or lack of work status of injectors.

Application of E4 emulator:

"E4" emulator is designed for disconnection of petrol injectors in a vehicle that is equipped with a petrol injection engine and a “propane – butane” gas feed system.

Emulator tuning:

After the emulator is installed according to the installation diagram, set the injectors switch off delay time during switching over from petrol to gas. For that purpose, a potentiometer is installed at the connection on the device wall. The time of injectors disconnection is signaled by red LED that is visible on the other side of the connection.
